Answer:
In Math, she scored in the 93rd percentile, which is higher than the French percentile. So she did better on the Math exam as compared with the other incoming college students
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation , the zscore of a measure X is given by:
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.
On which exam did she do better as compared with the other incoming college students?
On the exam for which she had the higher z-score.
Franch:
Scored 85.
Mean 72, SD = 12. So
has a pvalue of 0.8810, so her French score is in the 88th percentile.
Math:
Scored 80
Mean 68, SD = 8. So
has a pvalue of 0.9332.
In Math, she scored in the 93rd percentile, which is higher than the French percentile. So she did better on the Math exam as compared with the other incoming college students
<u>Given:</u>
A square pyramid with a base edge length of 8 m and a slant height of 12 m.
<u>To find:</u>
The height of the pyramid.
<u>Solution:</u>
A right-angled triangle can be formed with the slant height, the height, and half the length of the base edge.
The slant height of the pyramid is 12 m long and is the hypotenuse of the right-angled triangle.
Assume the height of the pyramid is x and half the length of the base edge is m.
According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.
The hypotenuse measures 12 m while the other two sides measure 4 m and x m each.
m.
The height of the square-based pyramid is 11.313 m.

Answer:
Step-by-step explanation:
If this is in terms of angles, 4x+6 must be equal to 90 since it is half of the angle produced by a line (180°) So solving for 4x+6=90, x=21
