The central angles are formed at point O, which is the center of the circle.

All the central angles are marked in the attachment.

The central angles are

: $m\angle AOC$ . This is a right angle and it is 180 degrees.

: $m\angle AOB$

A high school student took two college entrance exams, scoring 1070 on the SAT and 25 on the ACT. Suppose that SAT scores have a

antoniya [11.8K]

Answer:

Due to the higher z-score, he did better on the SAT.

Step-by-step explanation:

When the distribution is normal, we use 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.

Determine which test the student did better on.

He did better on whichever test he had the higher z-score.

SAT:

Scored 1070, so $X = 1070$

SAT scores have a mean of 950 and a standard deviation of 155. This means that $\mu = 950, \sigma = 155$ .

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

$Z = \frac{1070 - 950}{155}$

$Z = 0.77$

ACT:

Scored 25, so $X = 25$

ACT scores have a mean of 22 and a standard deviation of 4. This means that $\mu = 22, \sigma = 4$

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

$Z = \frac{25 - 22}{4}$

$Z = 0.75$

Due to the higher z-score, he did better on the SAT.

17=p-3-3p i need to show my work but i dont know how

nikklg [1K]

17 = p - 3 - 3p
17 = -2p - 3
17 + 3 = -2p
20 = -2p
-20/2 = p
-10 = p <==

the book is 300 pages david can read 1.8 pages per minute he only ha sone hour per day to read hom many days will it take him to

irina1246 [14]

Answer:

1 day

Step-by-step explanation:

i don't know hot to explain it, but technically i multiplied 1.8 time 60 (because there is 60 minutes in an hour, which will equal 108. now i multiplied 108 times 24 to see how many pages he can read in a day and it gave me 2592 and he only has to read 300 pages. So technically he can read 8 or more books of 300 pages in a day.
