E are given with two functions: h(x) = x – 7 and g(x) = x2. In this problem, we are asked to determine the value of g(h(5)). first we get g(h(x)) which is equal to (x-7)2, when x is substituted by 5, then g(h(5)) = (5-7)^2 equal to 4
Answer:
<u>The correct answer is A. 109</u>
Step-by-step explanation:
1. Let's review all the information given to answer the question correctly:
Mean of candies in bags = 145
Standard deviation = 3
Number of bags of candies on a shelf = 160
2. About how many bags of candies are expected to have between 142 candies and 148 candies?
Let's recall that in a normal distribution, the 68.2% of the sample or the population is between minus one and plus one time the standard deviation.
For our case, the 68.2% of the bags of candies are expected to have between minus one time the standard deviation (145 - 3) and plus one time the standard deviation (145 + 3).
<u>It means that 109 bags (0.682 * 160) are expected to have between 142 and 148 candies. The correct answer is A. 109.</u>
If you flipped the picture, it would be 60 degrees. But since its not flipped, it could possibly be 120 degrees since all sides are equal as the sides are parallel to each other.
Hope this helps.
