Your answer is ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

We know that ∠7 and ∠8 are supplementary because they form a straight line, and straight lines have a total of 180 degrees.

Since the two angles are supplementary, we can eliminate the 2nd and 3rd choices.

∠7 and ∠8 are not corresponding angles, which leaves us with option 4.

Best of luck!

The last statement. they are supplementary angles because they make 180 degrees. and they aren't corresponding, they're adjacent, meaning side by side sharing an arm. and they form a straight line

The blood cholesterol levels of men aged 55 to 64 are approximately normally distributed with mean 222 mg/dl and standard deviat

Answer:

It is provided that 10% of the men aged 55 to 64 have cholesterol level 270 mg/dl or higher.

Step-by-step explanation:

Let X = blood cholesterol levels of men aged 55 to 64 years.

The random variable X follows a Normal distribution with mean μ = 222 mg/dl and standard deviation σ = 37 mg/dl.

It is provided that 10% of the men aged 55 to 64 have cholesterol level x mg/dl or higher.

Compute the value of x as follows:

$P(X\geq x)=0.10\\P(\frac{X-\mu}{\sigma}\geq \frac{x-222}{37})=0.10\\P(Z\geq z)=0.10\\1-P(Z$

Use the z-table to compute the value z for the probability 0.90.

The value of z is 1.29.

Compute the value of x as follows:

$z=\frac{x-\mu}{\sigma}\\1.29=\frac{x-222}{37} \\x=222+(1.29\times37)\\=269.73\approx270$

Thus, 10% of the men aged 55 to 64 have cholesterol level 270 mg/dl or higher.
