Answer:

£21

Step-by-step explanation:

We know

Three women earned a total of £36. They shared the £36 in a ratio of 7:3:2. Meaning for every £12, one receives £7, one receives £3, and one receives £2.

Donna receives the largest amount working out the amount Donna receives.​ Meaning Donna receives £7.

To get from 12 to 36, we time 3.

We take

7 x 3 =  £21

So, Donna receives £21

Consider the cubic equation,

x³ - x² = 9 (x - 1)

We can solve this by factoring:

x³ - x² - 9x + 9 = 0

x² (x - 1) - 9 (x - 1) = 0

(x² - 9) (x - 1) = 0

(x - 3) (x + 3) (x - 1) = 0

So the cubic has roots at x = 3, x = -3, and x = 1. Split the real line into the open intervals (-∞, -3), (-3, 1), (1, 3), and (3, ∞). Check if the inequality holds for some test point taken from each interval:

• in (-∞, -3), take x = -4. Then

(-4)³ - (-4)² = -80

9 (-4 - 1) = -45

but -80 > -45 is not true. So this interval is not in the solution set.

• in (-3, -1), take x = -2. Then

(-2)³ - (-2)² = -12

9 (-2 - 1) = -27

and -12 > -27 is true. So x in (-3, -1) satisfies the inequality.

• in (1, 3), take x = 2. Then

2³ - 2² = 4

9 (2 - 1) = 9

but 4 > 9 is not true.

• in (3, ∞), take x = 4. Then

4³ - 4² = 48

9 (4 - 1) = 27

and 48 > 27 is true.

So, the complete solution set is

(-3, -1) U (3, ∞)

Confounding variables can affect the relationship between caffeine consumption and heart disease in a correlational study of police officers. Controlling for these variables is necessary to accurately assess the relationship.

The fact that the officers in the study could not be randomly assigned to high and low caffeine groups suggests that the results of the study may be due to confounding variables. A confounding variable is a third variable that is correlated with both the independent variable (in this case, caffeine consumption) and the dependent variable (in this case, heart disease). If a confounding variable is present, it can make it difficult to determine the true relationship between the independent and dependent variables.

For example, if the officers who consume more caffeine also have other unhealthy habits (such as smoking or eating unhealthy diets) that increase their risk of heart disease, it may be difficult to determine the true effect of caffeine on heart disease. In this case, the unhealthy habits would be the confounding variable, and controlling for these variables would be necessary to accurately assess the relationship between caffeine consumption and heart disease.

Year 2030 there will be 50g

Year 2035 there will be 35g

Year 2040 there will be 20g

But we want to get 25g in how many years

1 year takes 3g

If a football team gained \(2\frac{3}{4}\) yards and then lost \(4\frac{3}{5}\) yards on the next play, then their total loss is  \(1\frac{17}{20}\) yards

The total yards they gained in first match =  \(2\frac{3}{4}\) yards

Convert the mixed fraction to the simple fraction

\(2\frac{3}{4}\) yards = 11/4 yards

The total yards they loss in second match = \(4\frac{3}{5}\) yards

Convert the mixed fraction to the simple fraction

\(4\frac{3}{5}\) yards = 23/5 yards

Total loss = The total yards they loss in second match- The total yards they gained in first match

Substitute the values in the equation

Total loss = 23/5 - 11/4

= 37/20 yards

Convert the simple fraction to the mixed fraction

37/20 yards = \(1\frac{17}{20}\) yards

Hence, If a football team gained \(2\frac{3}{4}\) yards and then lost \(4\frac{3}{5}\) yards on the next play, then their total loss is  \(1\frac{17}{20}\) yards

Answer:

x = -175

Step-by-step explanation:

Given:

⇒ \(-\frac{x}{7}-8=17\)

Solution:

Work:

\(-\frac{x}{7}-8=17\)

\(-\frac{x}{7}-8+8=17+8\)    ⇒ Add 8 to both sides

\(-\frac{x}{7}=25\)

\(7\left(-\frac{x}{7}\right)=25\cdot \:7\) ⇒ Multiply both sides by 7

-x = 175

\(\frac{-x}{-1}=\frac{175}{-1}\) ⇒ Divide both sides by -1

x = -175

Check:

Since, x = -175. We can substitute into the equation to check.

\(-\frac{-175}{7}-8=17\)

\(-\frac{-175}{7}=25\)

\(25-8=17\) ⇒ Statement = True (25 minus 8 is 17.

Hence, x = -175

The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.

Then time taken for the first trip will be

t₁ = 867 / 612

t₁ = 1.4167 hours

Then time taken for the second trip will be

t₂ = 1984 / 744

t₂ = 2.6667 hours

Then the average speed is the ratio of the total distance to the total time.

The total distance will be

Total distance = 867 + 1984

Total distance = 2851 miles

The total time will be

Total distance = 1.4167 + 2.6667

Total distance = 4.0834 hours

Then the average speed will be

Average speed = 2851 / 4.0834

Average speed = 698.19 mi/h

Answer:

Se necesitan 810 baldosas de \( \\ 400cm^{2}\) (baldosas cuadradas de 20cm de lado) para cubrir un patio igual rectangular que se cubren con 540 baldosas de \( \\ 600cm^{2}\).

Step-by-step explanation:

Estrategia para resolver el problema

Para este problema es necesario saber el área de las baldosas de 20cm de lado. Luego debemos determinar, por regla de tres simple proporcional inversa, la cantidad de baldosas necesarias para cubrir un patio igual al que se cubrió con 540 baldosas de \( \\ 600cm^{2}\). Es una manera de resolver este problema.

Determinación del área de las baldosas de 20cm de lado

El área de un cuadrado es igual al lado de éste elevado al cuadrado:

\( \\ A_{cuadrado} = l * l = l^{2}\)

Si la baldosa es cuadrada y tiene 20cm de lado, entonces su área es:

\( \\ A = 20cm * 20cm = {(20cm)}^2\)

\( \\ A = 400cm^{2}\)

Por lo tanto, el área de la baldosa es de \( \\ A = 400cm^{2}\).

Uso de proporciones para resolver una regla de tres simple inversa

Recordemos también que una razón es la relación que guarda un cantidad con otra y se expresa:

\( \\ \frac{a}{b}\)

Una proporción es el resultado de igualar dos razones:

\( \\ \frac{a}{b} = \frac{c}{d}\)

Ahora debemos resolver el siguiente problema: si se usaron 540 baldosas de \( \\ A = 600cm^{2}\) para cubrir un patio rectangular: ¿cuántas baldosas de \( \\ A = 400cm^{2}\) se necesitarán para cubrir un patio de igual tamaño?

Hay que considerar que a mayor área de la baldosa, menor número de baldosas se utilizarán. A menor área de la baldosa, mayor será el número de éstas que se utilizarán. Por lo tanto, es una relación inversamente proporcional.

Entonces, usando proporciones, el problema se puede plantear de la siguiente manera:

\( \\ \frac{540\;baldosas}{X\;baldosas} = \frac{400cm^{2}}{600cm^{2}}\)

Que es equivalente a

\( \\ \frac{X\;baldosas}{540\;baldosas} = \frac{600cm^{2}}{400cm^{2}}\) [1]

Nótese que la razón entre baldosas es distinta a la razón entre las áreas, por ser cantidades inversamente proporcionales: la razón entre el número de baldosas es inversa a la razón entre las áreas de éstas.

Es importante también considerar que se debe establecer estas razones entre la misma especie de objeto a comparar (baldosas-baldosas y área-area).

Entonces, resolviendo la ecuación [1], tenemos que:

\( \\ \frac{X\;baldosas}{540\;baldosas} = \frac{600cm^{2}}{400cm^{2}}\)

Para despejar X, multiplicamos a cada lado de la igualdad por 540 baldosas.  

\( \\ \frac{X\;baldosas}{540\;baldosas} * 540\;baldosas = \frac{600cm^{2}}{400cm^{2}} * 540\;baldosas\)

\( \\ X\;baldosas * \frac{540\;baldosas}{540\;baldosas} = \frac{600cm^{2}}{400cm^{2}} * 540\;baldosas\)

\( \\ X\;baldosas * 1 = \frac{600cm^{2}}{400cm^{2}} * 540\;baldosas\)

\( \\ X\;baldosas = \frac{600cm^{2}}{400cm^{2}} * 540\;baldosas\)

Simplificando:

\( \\ X\;baldosas = \frac{6}{4} * 540\;baldosas\)

\( \\ X\;baldosas = \frac{3}{2} * 540\;baldosas\)

\( \\ X\;baldosas = \frac{3 * 540}{2}\;baldosas\)

Podemos proceder de la siguiente manera, sabiendo que 540 es para y es divisible por 2.

\( \\ X\;baldosas = 3 * \frac{540}{2}\;baldosas\)

\( \\ X\;baldosas = 3 * 270\;baldosas\)

\( \\ X\;baldosas = 810\;baldosas\)

Es decir, se necesitan 810 baldosas de \( \\ 400cm^{2}\) (baldosas cuadradas de 20cm de lado) para cubrir un patio rectangular que se cubren con 540 baldosas de \( \\ 600cm^{2}\).

The vector space that has exactly one basis is the trivial vector space, which is the vector space containing only the zero vector.

A basis for a vector space is a set of linearly independent vectors that span the entire space. In a non-trivial vector space (a space that contains more than just the zero vector), there are infinitely many possible bases. This is because any set of linearly independent vectors that span the space can be used as a basis.

However, in the trivial vector space, there is only one vector (the zero vector), and it is linearly independent of itself. Therefore, the trivial vector space has exactly one basis, which is the set containing only the zero vector. Any other set of vectors in the trivial vector space is linearly dependent, and therefore cannot be used as a basis.

The random variable x in this case is a binomial random variable, representing the number of cars that need to be inspected until a car fails an inspection. A binomial random variable is defined as the number of successes, “s”, in “n” independent trials. In this case, “s” would be 1 (the single failure) and “n” would be the number of cars that John inspects until a car fails inspection.

The probability of success, “p”, in this case is 0.06 since 6% of cars fail inspection. The probability of failure is “q”, which would be 0.94 in this case (1 - 0.06). The mean, “μ”, of the random variable x is equal to n * p, or the total number of trials times the probability of success. In this case, the mean would be equal to n * 0.06, or 6%.

The variance, “σ2”, of the random variable x is equal to n * p * q, or the total number of trials times the probability of success times the probability of failure. In this case, the variance would be equal to n * 0.06 * 0.94, or 5.64%.

The binomial random variable x can be used to calculate the expected number of inspections it will take John until a car fails an inspection, as well as the probability of a car failing an inspection. By knowing the probability of success, the number of trials, and the probability of failure, we can calculate the mean, variance, and expected value of the binomial random variable x.

The person who drink more water is Troy and he drinks 0.3 L more than Whitney

It is the transformation of a value expressed in one unit of measurement into an equivalent value expressed in another unit of measurement of the same nature.

To solve this problem, we have to do the conversion of units with the given information:

Information about the problem:

By converting the unit from mL to L, we have:

1500 mL * (1 L / 1000 mL ) = 1.5 L

Comparing the volume of water that Whitney and Troy drink we have:

1.8 L > 1.5 L

Troy > Whitney

Troy drinks more water than Whitney

Calculating how much water Troy drinks more, we get:

Volume difference = Troy - Whitney

Volume difference = 1.8 L - 1.5 L

Volume difference = 0.3 L

Answer:

1. there were 24 chocolates in the box at first.

2. the boy with the smallest share received 6 chocolates.

Explanation:

let's represent the number of chocolates in the box with 8x.

the first boy got ⅜ × 8x  = 3x chocolates. now, there are 8x - 3x = 5x chocolates remaining.

the second boy got ⅖ × 5x = 2x chocolates. now, there are 5x - 2x = 3x chocolates remaining.

3x = 9 chocolates

x = 3 chocolates

since the original number of chocolates was represented by 8x, we now know that there were 8 × 3 = 24 chocolates in the box at first.

the first boy got 9 chocolates, the second boy got 6 chocolates and the last boy got 9 chocolates. thus, the boy with the smallest share got 6 chocolates.

Each paintbrush costs the same amount, so x represents the number of gallons of paint that Ben purchased, and 6x represents the cost of that paint plus the cost of six paintbrushes.

The equation y = 6x + 30 models the total cost of Ben's purchases.Each paintbrush costs the same amount.

We need to  determine what the value of x = 0 represents in the situation?

The value of x  represents the number of gallons of paint Ben purchased. When x=0, there is no gallon of paint purchased by Ben, and hence the total cost is just the cost of buying the paintbrushes which is given by 30 dollars.

Similarly,When x = 1, it represents the number of gallons of paint purchased. Hence the total cost of purchasing 1 gallon of paint and some paintbrushes is given byy = 6(1) + 30 = $36

This means that the total cost of purchasing 1 gallon of paint and some paintbrushes is $36.

a. The critical value for a one-tailed test at a 0.05 significance level with 16 degrees of freedom is approximately 1.745. b. The critical values for a two-tailed test at a 0.01 significance level with 16 degrees of freedom are approximately -2.921 and 2.921 (symmetrical about zero).

For smaller samples, t distributions are flatter and more spread out than the standard normal (z) distribution because the t distribution takes into account the additional uncertainty introduced by estimating the population standard deviation from the sample standard deviation. In smaller samples, the sample standard deviation may not accurately represent the true population standard deviation, resulting in greater variability in the t distribution.

As the sample size increases, the t distributions start to resemble the standard normal (z) distribution more closely. This is because as the sample size increases, the sample standard deviation becomes a more reliable estimate of the population standard deviation. Consequently, the t distribution converges towards the z distribution, which assumes a known population standard deviation.

Degrees of freedom (df) in statistics refer to the number of independent pieces of information available to estimate a parameter. In the context of the t distribution, degrees of freedom represent the number of observations in the sample that are free to vary. When calculating the sample mean and sample standard deviation, one degree of freedom is lost because the mean is used to estimate the population mean.

An example that explains why you subtract 1 from the sample size for degrees of freedom is as follows: Suppose you have a sample of 10 individuals and you want to estimate the population mean. If you know the sample mean, you can calculate the values of the first 9 individuals, but the value of the 10th individual is no longer free to vary since it is determined by the other 9 values. Therefore, you have 9 degrees of freedom (10 - 1).

For question #4:

a) For a one-tailed t-test with n - 16 degrees of freedom and a significance level of 0.05, you can find the critical value from the t-distribution table. The critical value for a one-tailed test at a 0.05 significance level with 16 degrees of freedom is approximately 1.745.

b) For a two-tailed t-test with n = 16 and a significance level of 0.01, the critical values are found by dividing the significance level by 2 and finding the corresponding values from the t-distribution table. The critical values for a two-tailed test at a 0.01 significance level with 16 degrees of freedom are approximately -2.921 and 2.921 (symmetrical about zero).
