Answer:
c. the biology test
Step-by-step explanation:
To answer this problem we need to calculate the z-score of both tests, using the formula:
z = (x - μ) / σ
Where x is Sue's score, μ is the mean, and σ is the standard deviation.
- For the <u>biology test</u>, the z-score is:
z = (76 - 70) / 7 = 6/7 = 0.857
- For the <u>math test</u>, the z-score is:
z = (76 - 75) / 10 = 1/10 = 0.100
Because the z-score for the biology test is greater than the z-score for the math test, Sue did better in the biology test, in comparison to the rest of the class.

Answer:
<h3>5 feet</h3>
Step-by-step explanation:
The set up will give a right angles triangle with:
length of the ladder as the hypotenuse h = 13 foot
The distance from the base of the house to the top of the ladder is the opposite side (y) = 12 feet
The distance of the base of the ladder from the base of the house wil be the adjacent side (x)
Using the pythagoras theorem to get x:
h² = x²+y²
13² = x²+12²
x² = 13²-12²
x² = 169 -144
x² = 25
x = √25
x = 5 feet
Hence the distance of the base of the ladder from the base of the house is 5 feet long
