The factor in the graph that supports the idea that the greater the rainfall in June through August, the fewer acres are burned by wildfires is the negative correlation between rainfall and acres burned.

The graph shows a negative correlation between the amount of rainfall in June through August and the number of acres burned by wildfires. As the amount of rainfall increases, the number of acres burned decreases. This suggests that wetter weather can help reduce the risk of wildfires.

The graph provides a visual representation of the relationship between rainfall and wildfires. It shows that there is a clear negative correlation between the two variables. This means that as one variable increases, the other decreases. In this case, the variable of interest is the number of acres burned by wildfires. The graph shows that when there is less rainfall in June through August, more acres are burned by wildfires. Conversely, when there is more rainfall during these months, fewer acres are burned. This makes sense because rainfall can help reduce the risk of wildfires by making vegetation less dry and therefore less susceptible to catching fire. Additionally, wetter weather can help firefighters contain and extinguish fires more quickly and effectively.

a. The probability that none will pass inspection is

P(x = 0) = \(^{10}C_{0}(0.05)^{0}(0.95)^{10}\)

P(x = 0) = 0.5987

b. The probability that all will pass inspection is

P(x = 10) = \(^{10}C_{0}(0.05)^{10}(0.95)^{0}\)

P(x = 10) = 0.5987

c. The probability that exactly two will not pass inspection is

P(x = 2) = \(^{10}C_{2}(0.05)^{2}(0.95)^{8}\)

P(x = 2) = 0.0746

a. The probability that none will pass inspection is 0.001%.

b. The probability that all will pass inspection is 59.87%.

c. The probability that exactly two will not pass inspection is 0.27%.

d. The probability that more than three will not pass inspection is 0.0102.

e. The probability that fewer than two will not pass inspection is 6.48%.

In statistics, probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 means that the event is impossible, and 1 means that the event is certain.

In a particular county of our state, it was revealed that 5% of all automobiles did not pass inspection. This means that the probability of an automobile not passing inspection is 0.05, and the probability of an automobile passing inspection is 0.95.

To find the probability of none of the ten automobiles passing inspection, we need to multiply the probability of an automobile not passing inspection by itself ten times since the events are independent. Therefore, the probability of none of the ten automobiles passing inspection is 0.05¹⁰, which is approximately 0.00001 or 0.001%.

To find the probability of all ten automobiles passing inspection, we need to multiply the probability of an automobile passing inspection by itself ten times since the events are independent. Therefore, the probability of all ten automobiles passing inspection is 0.95¹⁰, which is approximately 0.5987 or 59.87%.

To find the probability of exactly two of the ten automobiles not passing inspection, we need to use the binomial distribution formula. The formula is P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, p is the probability of success, and (n choose k) is the binomial coefficient. Therefore, the probability of exactly two of the ten automobiles not passing inspection is P(X=2) = (10 choose 2) * 0.05² * 0.95⁸, which is approximately 0.0027 or 0.27%.

The complement rule states that the probability of an event occurring is equal to one minus the probability of the event not occurring. Therefore, the probability of more than three of the ten automobiles not passing inspection is 1 - P(X<=3), where P(X<=3) is the probability of three or fewer automobiles not passing inspection.

To find P(X<=3), we can use the binomial distribution formula with k=0,1,2, and 3. Therefore,

P(X<=3) = P(X=0) + P(X=1) + P(X=2) + P(X=3)

=> (10 choose 0) * 0.05⁰ * 0.95¹⁰ + (10 choose 1) * 0.05¹ * 0.95⁹ + (10 choose 2) * 0.05² * 0.95⁸ + (10 choose 3) * 0.05³ * 0.95⁷, which is approximately 0.9898 or 98.98%.

Therefore, the probability of more than three of the ten automobiles not passing inspection is 1 - 0.9898, which is approximately 0.0102.

To find the probability of fewer than two of the ten automobiles not passing inspection, we need to use the complement rule again. The probability of fewer than two automobiles not passing inspection is the same as the probability of one or zero automobiles not passing inspection.

To find the probability of more than two automobiles not passing inspection, we can use the complement rule again:

=> P(X>2) = 1 - P(X<=2) = 1 - (P(X=0) + P(X=1) + P(X=2)) = 1 - [((10 choose 0) * 0.05⁰ * 0.95¹⁰ + (10 choose 1) * 0.05¹ * 0.95⁹ + (10 choose 2) * 0.05² * 0.95⁸]

Answer:

Step-by-step explanation:

450-100=350

350/50=7

7 months

Leanna has been saving for 7 months to have the balance of $450.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as linear equation in one variable.

Let's suppose the Leanna has been saving the money for 'x' months

It means total months = x

Intial balance = $100

Each month she deposit = $50

After x months she will have  = $450 (with initial balance)

We can frame a linear equation in one variable such that:

50x = 450 - 100  (without initial balance)

50x = 350 (divide by 50 on both sides)

x = 7 months

Thus, Leanna has been saving for 7 months to have the balance of $450.

The probability that a pupil uses neither pool nor gym is 11/70

Probability is the likelihood that an event will happen. This can range from an event being impossible to some likelihood to being absolutely certain. In math terms, probability is on a scale from 0 to 1. Zero means the event is impossible, like rolling a seven on a die that only has digits from 1 to 6.

Number of pupil that can use pool and gym = 28

Number of people that can use pool = 48

Number of people that can use gym = 39

Number of people that can use pool only = 48 - 28 which is 20

Number of people that can use gym only = 39 - 28 = 11

Total number of persons that can use either pool, gym or both = 20 + 11 + 28 which is 59

Number of people that cannot use either or both of the facilities = 70 - 59 which is 11.

Probability = required outcome / possible outcome

Required outcome = 11

possible outcome = 70

Probability = 11/70

In conclusion, the probability that a pupil uses neither swimming pool nor gym is 11/70

A Magic Square is a square grid of numbers in which the sum of every row, column, and diagonal is equal.

One way to approach this is to start with the center number and work outwards.

Since every row, column, and diagonal adds up to 0, the center number must be 0.

From there, we can fill in the rest of the numbers systematically.
For example, in the top row, we need to find two numbers that add up to 0.

We could choose 1 and -1, or 2 and -2, or any other pair of opposite numbers.

Let's choose 1 and -1 for the top row.

Then, we can fill in the bottom row with the same numbers in reverse order.
Next, we can fill in the left and right columns.

Since every column must add up to 0, we need to choose numbers that add up to 0 in each column.

Let's choose 3 and -3 for the left column, and 2 and -2 for the right column.

Finally, we can fill in the diagonals with the remaining numbers.

In this particular Magic Square, every row, column, and diagonal adds up to 0.

We can choose 4 and -4 for one diagonal, and 5 and -5 for the other diagonal.
By following this systematic approach, we can complete the Magic Square with the following numbers:
           3  2 -1
           0  0  0
          -3 -2  1
This Magic Square is a great example of the fascinating patterns and mathematical properties that can be found in numbers. It is also a fun puzzle to solve and can provide hours of entertainment for people of all ages.

The measures of the corresponding inscribed angles, and then add those angles together to find the measure of angle L. Therefore, the measure of angle L is 64 degrees.

The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc. In other words, if we have an angle whose vertex is on the circumference of a circle, and whose sides intersect two points on the circumference, then the measure of the angle is half the measure of the arc between those two points.

In this problem, we are given the measures of two arcs, DR and SV, and we want to find the measure of angle L. We can start by using the Inscribed Angle Theorem to find the measures of the corresponding inscribed angles. Let's call these angles A and B, where A is the inscribed angle that intercepts arc DR, and B is the inscribed angle that intercepts arc SV.

Using the Inscribed Angle Theorem, we can find that m∠A=12m⌢DR=12(34∘)=17∘m∠B=12m⌢SV=12(94∘)=47∘

To find the measure of angle L, we simply add angles A and B together: m∠L=m∠A+m∠B=17∘+47∘=64∘

Therefore, the measure of angle L is 64 degrees.

Answer:

Step-by-step explanation:

If the resulting F-statistic is less than the critical value, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the variances are significantly different.

The F-test is a statistical test used to compare the variances of two groups.

In this problem, we will use it to compare the variance of the value added by the manufacturer and the variance of the cost of materials in manufacturing. The F-test is performed by dividing the larger variance by the smaller variance. The resulting F-statistic is then compared to the critical value of an F-distribution with degrees of freedom equal to the sample size minus one for each group.

Before we can perform the F-test, we need to determine which variable will be group 1. Typically, the variable with the smaller mean is designated as group 1. This is because we want to minimize the chance of making a type II error, which is failing to reject the null hypothesis when it is false. If we designated the variable with the larger mean as group 1, we might not detect a significant difference between the groups, even if one exists.

Once we have designated which variable will be group 1, we can perform the F-test. If the resulting F-statistic is greater than the critical value of the F-distribution, we reject the null hypothesis and conclude that the variances are significantly different.

Answer:

Step-by-step explanation:

Para determinar las dimensiones del piso, debemos considerar la cantidad de baldosas y las dimensiones de cada una. Sabemos que hay 50 baldosas disponibles y que cada una tiene un tamaño de 20x25 cm.

Si multiplicamos el número de baldosas por las dimensiones de cada baldosa, obtendremos el área total que cubren las baldosas en el piso.

50 baldosas * (20 cm * 25 cm) = 50 * 500 cm² = 25000 cm²

El área total que cubren las baldosas es de 25000 cm². Para encontrar las dimensiones del piso, necesitamos determinar las dimensiones de un rectángulo cuyo área sea igual a 25000 cm².

Podemos factorizar 25000 para encontrar sus dimensiones de manera más sencilla. La factorización puede variar, pero en este caso, se puede descomponer en:

25000 = 250 * 100 = 25 * 10 * 100 = 5 * 5 * 2 * 10 * 100

Podemos agrupar estos factores para obtener un rectángulo con dimensiones proporcionales:

5 * 5 = 25

2 * 10 = 20

100 = 100

Por lo tanto, las dimensiones del piso son 25 cm de ancho por 20 cm de largo.

Para visualizar esto en una gráfica, podemos representar el piso como un rectángulo con las dimensiones calculadas de 25 cm x 20 cm.

Answer:

- \(\frac{1}{2}\)

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

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

Here [ a, b ] = [ - 8, 2 ] , thus

f(b) = f(2) = - 4 ← read from graph

f(a) = f(- 8) = 1 ← read from graph, thus

average rate of change = \(\frac{-4-1}{2-(-8)}\) = \(\frac{-5}{10}\) = - \(\frac{1}{2}\)

The amount of photosynthesis will increase as the intensity of light increases up to a certain point, after which it will level off or decrease due to factors such as heat and damage to the plant.

The amount of photosynthesis that takes place in a certain plant depends on the intensity of light x according to the equation f(x) = 180x² − 40x³.

There are a few ways to find the maximum value of this quadratic function, but one common method is to use calculus.

To find the maximum value of a function, we need to find its critical points, which are the values of x where the derivative is zero or undefined.

We can then test these critical points to see which one gives the maximum value.

Let's find the derivative of the function f(x):f(x) = 180x² − 40x³f'(x) = 360x − 120x²

Now we need to find the critical points by solving the equation 360x − 120x² = 0.

Factoring out 120x, we get:120x(3 − x) = 0So the critical points are x = 0 and x = 3.

We can now test these points to see which one gives the maximum value of f(x).

Testing x = 0:f(0) = 180(0)² − 40(0)³ = 0Testing x = 3: f(3) = 180(3)² − 40(3)³ = −540

So the maximum value of f(x) is 0, which occurs at x = 0.

Therefore, the maximum amount of photosynthesis occurs when the intensity of light is zero.

However, this is not a practical situation because plants need light to survive.

Step-by-step explanation:

The random sample of \(24\) students has a mean of \(1.9149\), and the data suggests that the mean is \(20^{0}\).

x = (xi) / n is the general solution for computing the sample mean. Thus, xi refers to all X sample values, xi represents the sampling distribution, and n is the total number of specimen terms inside the data collection.

The statistic known as the sampling distribution is created by arithmetically averaging the values of the variables in a group. The sample mean is an estimate of the anticipated value if the sample is taken from probabilistic with a common expected value.

(a) Sample mean \(= (17 + 21 + 20 + 19 + 23 + 22 + 20 + 20 + 18 + 21 + 19 + 24 + 22 + 20 + 19 + 20 + 19 + 20 + 21 + 22 + 23 + 21 + 18 + 22)/24 = 20.5\)Sample standard deviation \(= 1.9149\)

Next, we can use a t-distribution with \(23\) degrees of freedom

Confidence interval \(= (20.5 - 0.8277, 20.5 + 0.8277) = (19.6723, 21.3277)\)

Answer:

the critical value for r at \(r_{0.05, 23}\) = 0.396

Step-by-step explanation:

Given that:

the linear correlation coefficient r = 0.767

the sample size n = 25

the level of significance ∝ = 0.05

The degree of freedom is expressed with the formula df = n - 2

 df = 25 - 2

 df = 23

the critical value for r at \(r_{0.05, 23}\) = 0.396

The linear correlation coefficient r = 0.767 is not in the region between the critical values of -0.396 and +0.396. We can therefore conclude that the linear correlation coefficient is significant.
