Answer:  15.59 or 9√3

Step-by-step explanation:

We can use the Pythagorean Theorem to calculate the third side.

c² = a² + b²   In a 30 60 90 Triangle, the hypotenuse is twice the length of the short leg of the right angle.

c is the hypotenuse. a is the short leg

18² = 9² + b²

324 = 81 + b²  Subtract 81 from both sides.

324 - 81 = b²  becomes b² = 243   Take the square root of both sides

b = 15.5884 . This can  be rounded to 15.59 or 15.6 depending on significant digits or amount of precision required.

The proportions of the sides of the 30 60 90 triangle can also be used:

2² = 1² + b²

4 = 1 + b²

3 = b²

√3 = b

You can always multiply the length of the short leg by √3 to get the length of the side opposite the 60° angle

A function rule that relates the total distance a car can travel d as a function of the number of gallons of gas in its tank g is given by: d = 20g

A proportion can be defined as an equation which is typically used to represent the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

Mathematically, a rule that relates the total distance (d) which a car can travel as a function of the number of gallons (g) of gas in its tank:

d = 20g

Where:

In conclusion, the total distance (d) traveled by most cars is directly proportional to the number of gallons (g) of gas in their tank at a constant rate of 20 miles per gallon of gas.

Based on the results of the sleep study, we can determine that the participant is most likely an infant or a newborn. Since a newborn sleeps 50% of their time in REM sleep as it helps in their growth and brain development.

REM sleep is one of the phases of sleep. In this phase, your brain waves are high-frequency and low-amplitude, and it is the time when your brain is most active. The sleep study in which the participant began the sleep cycle with REM sleep and spent 50 percent of the time in REM sleep suggests that the participant is a newborn or an infant. The newborns sleep 50% of their time in REM sleep as it helps in their growth and brain development.

As a person ages, the time spent in REM sleep decreases, and they spend more time in the deeper stages of non-REM sleep. In adults, REM sleep makes up 20-25% of the total sleep time, while in newborns, it can be as high as 50%. Therefore, based on the results of the sleep study, we can determine that the participant is most likely an infant or a newborn.

-2x + 2x - 6 < 0 + 2x

- 6 < 2x                         We did so we would be dividing by a number greater than 0.                         Divide by + 2

4)For answer of no 4

the third side can be gotten by pythagoras theorem;

It says,

hyp^2=opp^2 + adj^2

hyp= ?

opp=30

adj=40

so,

hyp^2=30^2 + 40^2

hyp^2=900+1600

hyp^2=2500

square rooting both sides,

hyp=50ft

Therefore the missing side is 50ft

5) for number 5

opp is missing

remember,

hyp^2=opp^2+adj^2

opp^2= hyp^2-adj^2

opp^2=41^2-40^2

opp^2=1681-1600

opp^2=81

The binomial probability model is useful in situations with discrete-valued numerical variables. Hence, the answer is option (a) discrete-valued numerical variables.

The binomial distribution is a probability model that describes the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes (e.g., success or failure, heads or tails, etc.).

The binomial distribution can be used to model a wide range of real-world scenarios, such as the number of defective products in a batch of goods, the number of heads in a series of coin flips, or the number of people who respond positively to a survey question.

Therefore, the correct option is (a)  discrete-valued numerical variables.

Step-by-step explanation:

If the null hypothesis is rejected, it suggests that there is evidence to support the claim that the mean weight of Take-a-Bite snack food is less than 175 grams.

What is the standard deviation?

The standard deviation is a measure of the dispersion or variability of a set of data points. It quantifies how much the individual data points deviate from the mean of the data set.

To test the claim that the mean weight of Take-a-Bite snack food is less than 175 grams, we can conduct a one-sample t-test. Here's how we can perform the test at a significance level of 0.05:

Step 1: State the null and alternative hypotheses:

Null Hypothesis (H0): The mean weight of Take-a-Bite snack food is equal to 175 grams.

Alternative Hypothesis (H1):

The mean weight of Take-a-Bite snack food is less than 175 grams.

Step 2: Determine the test statistic:

Since the population standard deviation is unknown, we use the t-test statistic. The test statistic for a one-sample t-test is calculated as: t = (sample mean - hypothesized mean) / (sample standard deviation / √n)

In this case, the sample mean is 172 grams, the hypothesized mean is 175 grams, the sample standard deviation is 8 grams, and the sample size is 70.

Step 3: Set the significance level: The significance level (alpha) is given as 0.05.

Step 4: Calculate the test statistic:

t = (172 - 175) / (8 / √70) ≈ -1.158

Step 5: Determine the critical value and p-value:

Since we are conducting a one-tailed test to check if the mean weight is less than 175 grams, we need to find the critical value or p-value for the lower tail.

Using a t-distribution table or statistical software, we can find the critical value or p-value associated with a t-statistic of -1.158 and degrees of freedom (df) equal to n - 1 (70 - 1 = 69) at a significance level of 0.05.

Step 6: Make a decision:

If the p-value is less than the significance level (0.05), we reject the null hypothesis. If the critical value is greater than the test statistic, we reject the null hypothesis.

Step 7: Interpret the results:

Based on the calculated test statistic and critical value or p-value, make a conclusion about the null hypothesis. If the null hypothesis is rejected, it suggests that there is evidence to support the claim that the mean weight of Take-a-Bite snack food is less than 175 grams. If the null hypothesis is not rejected, there is insufficient evidence to support the claim.

A share in the ratio of 2:3:1 respectively Dan received $132.

To determine how much money Dan received, we need to calculate his share based on the given ratio. The total ratio is 2 + 3 + 1 = 6. To find the fraction that represents Dan's share, we divide his ratio by the total ratio: 3 / 6 = 1/2.

Next, we need to find the amount of money that corresponds to 1/2 of the total sum. We can do this by dividing the total amount of money by the total ratio and multiplying it by Dan's ratio: ($264 / 6) * 3 = $132.

Therefore, Dan received $132 out of the $264 that were shared among the three brothers. The ratio of 2:3:1 implies that Dan's share is three times the value of the smallest ratio, which is 2.

Using x, y, and z for price per bushel of wheat, corn, and rye, respectively, the given sales tell us ...

The easiest way to solve a system of equations like this is to make use of the matrix manipulation capabilities of a calculator. The attached calculator display shows the reduction of the augmented matrix of coefficients to "reduced row-echelon form". That puts the solution in the last column:

  x = y = 3.61, z = 1.91

The price per bushel for wheat and corn is the same: $3.61; the price per bushel for rye is $1.91.

Additional comment

The second attachment shows a solution using a graphing calculator. In this solution, an expression for z based on the first equation is used in the remaining two equations, which then tell us the values of x and y.

If you add all of the equations, you get 10x +10y +10z = 91.30, which gives you ...

  x + y + z = 9.13

This can be solved for any variable you may want to substitute into any pair of the equations. This approach avoids any messy fractions.

The probability that on exactly one of these three occasions the voter approves of the mayor's work is given as follows:

0.189 = 18.9%.

The mass probability formula, giving the probability of x successes, is of:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are given by:

The values of these parameters in the context of this problem are given as follows:

n = 3, p = 0.7.

Then the probability of exactly one success is calculated as follows:

P(X = 1) = 3!/(1!2!) x 0.7 x (0.3)² = 0.189 = 18.9%.
