The ACT score was better since the z-score of the ACT is greater than the z-score of the SAT. Then the correct option is B.
<h3>What is a normal distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The z-score is given as

In 1985, the average ACT score was 18 with a standard deviation of 6.
Also in 1985, the average SAT score was 500 with a standard deviation of 100.
Dr. Robertson took both tests in 1985 and scored a 26 on the ACT and a 620 on the SAT.
Then the z-score of the ACT will be

Then the z-score of the SAT will be

Then the ACT score was better since the z-score of the ACT is greater than the z-score of the SAT.

The triangle is a right triangle so use the Pythagorean theorem.
a² + b² = c²
15² + b² = 17²
225 + b² = 289
b² = 64
b = √64
b = 8

Answer: Elisa
Step-by-step explanation:
Since Elisa withdrew $23 at a time from her bank account and withdrew a total of $207, the number of times that Elisa withdrew will be:
= $207/$23
= 9 times
Since Frances withdrew $43 at a time from his bank account and withdrew a total of $172, the number of times that Frances withdrew will be:
= $172/$43
= 4 times.
Based on the calculations, we can see that Elisa made the greater number of withdrawal.
