The graph represents the line x = 3.

Since there is more than one y-value for the one x-value provided, this graph is not a function.

The range is infinite, as there are no limits shown on the graph, and the slope is undefined.

The domain is only 3, since the only x-value on the graph is 3.

Based on this information, the statements that are true will be:

C. This graph is not a function because the value x = 3 is assigned to more than one y-value.

E. The equation of this line is x = 3.

(Note that D says the graph <em>is a function</em>. The graph isn't a function, as there is more than one y-value for x = 3.)

In a randomly selected sample of 1169 men ages 35–44, the mean total cholesterol level was 210 milligrams per deciliter with a s

Aneli [31]

Answer:

The highest total cholesterol level a man in this 35–44 age group can have and be in the lowest 10% is 160.59 milligrams per deciliter.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 210, \sigma = 38.6$

Find the highest total cholesterol level a man in this 35–44 age group can have and be in the lowest 10%.

This is the 10th percentile, which is X when Z has a pvalue of 0.1. So X when Z = -1.28.

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

$-1.28 = \frac{X - 210}{38.6}$

$X - 210 = -1.28*38.6$

$X = 160.59$

The highest total cholesterol level a man in this 35–44 age group can have and be in the lowest 10% is 160.59 milligrams per deciliter.

Alexis is making cookies. The recipe says that she has to mix 192 grams of sugar into the flour. Alexis knows that 1 cup of this

Dmitrij [34]

For this case we can make the following rule of three:
1 cup ----------------> 128 grams
x ----------------------> 192 grams
From here, we clear the value of x.
We have then:
x = (192/128) * (1)
x = 1.5
x = 1 1/2
Answer:
She needs about 1 1/2 cups.
