Answer:

1,000 feet

Step-by-step explanation:

From point Q to point R, the x values change by 20 units while the y values stay the same. This side of the polygon has a length of 20

From point R to point S, the y values change by 30 units while the x values stay the same. This side of the polygon has a length of 30

From point S to point T, the x values change by 20 units while the y values stay the same. This side of the polygon has a length of 20

From point T to point Q, the y values change by 30 units while the x values stay the same. This side of the polygon has a length of 30

The total perimeter is 20 + 30 + 20 + 30 = 100 units, each unit represents 10 feet, so the total perimeter is 100(10) = 1,000 feet

Answer:

100 feet

Step-by-step explanation:

side lengths:

y2-y1 = /-10-10/ = 20 units

x2-x1= /20-(-10)/ = 30 units

20+20+30+30 = 100

Monica uses 3 tablespoons of milk in her custard recipe. The ratio of tablespoons to fluid ounces is 2 : 1. How many fluid ounce

Gwar [14]

Answer:” use

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal

Let x be the fluid ounces of milk does Monica use.

As per the statement:

Monica uses 3 tablespoons of milk in her custard recipe.

It is also given that:

The ratio of tablespoons to fluid ounces is 2 : 1.

by proportion definition we have;

by cross multiply we have;

3 = 2x

Divide both sides by 2 we have;

therefore, fluid ounces of milk does Monica use.”

A breakfast cereal producer makes its most popular product by combining just raisins and flakes in each box of cereal. The amoun

Using the normal distribution, it is found that there is a 0.9192 = 91.92% probability that the total amount of product is less than 575 g.

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

When two normal variables are added, the mean is the sum of the means while the standard deviation is the square root of the sum of the variances.

In this problem, the product is composed by flakes and raisins, and we have that:

$\mu_F = 370, \sigma_F = 24, \mu_R = 170, \sigma_R = 7$

Hence, the distribution for the total amount of product has <u>mean and standard deviation</u> given by:

$\mu = \mu_F + \mu_R = 370 + 170 = 540$

$\sigma = \sqrt{\sigma_F^2 + \sigma_R^2} = \sqrt{24^2 + 7^2} = 25$

The probability that the total amount of product is less than 575 g is the <u>p-value of Z when X = 575</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{575 - 540}{25}$

$Z = 1.4$

$Z = 1.4$ has a p-value of 0.9192.

0.9192 = 91.92% probability that the total amount of product is less than 575 g.
