Answer:
A) The applicant's SAT z-score has to be positive and large.
Step-by-step explanation:
The zscore measures how much above or below the mean a value is in a normally distributed sample. The value can be a grade, for example.
In a set with mean and standard deviation
, the zscore of a measure X is given by
.
When the zscore of X is negative and large, this means that the grade is on the very low side(very below the mean).
When the zscore of X is negative and small, this means that the grade is on the low side(a bit below the mean).
When the zscore of X is close to 0, the grade is close to the mean.
When the zscore of X is positive and small, this means that the grade is on the high side(a bit above the mean).
When the zscore of X is positive and large(Z > 1), this means that the test score is on a very high side.
The problem states that:
To get admitted to top universities, the applicant's SAT (Scholastic Aptitude Test) score must be on a very high side. So, the correct answer is:
A) The applicant's SAT z-score has to be positive and large.
Answer:
<u>10 sundaes</u> will be vanilla.
Step-by-step explanation:
Given:
Fernando is making 30 sundaes with mint, chocolate,and vanilla ice cream.
1/3 of the Sunday's are mint ice-cream.
And 1/2 of the remaining sundaes are chocolate.
The rest are vanilla.
Now, to find the number of sundaes that will be vanilla.
Fernando is making sundaes total = 30.
So, the quantity of sundaes that are mint ice-cream:
<em>Thus, 10 sundaes are mint ice-cream.</em>
So, the remaining sundaes are:
<em>Thus, the remaining sundaes are = 20.</em>
Now, to get the quantity of chocolate sundaes of the remaining sundaes:
<em>Hence, 10 sundaes are chocolate of the remaining 20 sundaes.</em>
<em>As, given the rest are vanilla.</em>
Now, to get the vanilla sundaes we subtract the 10 chocolate ice-cream from the 20 remaining sundaes:
Therefore, 10 sundaes will be vanilla.
