Answer:
a = -3
Step-by-step explanation:
You're correct.
The form of the equation you need is

Filling in our h, k, y, and x:
which simplifies to
which simplifies further to

Very good!!!! These can be tricky, but you got it!!
The first option,
both have to be negative, because they were originally both part of the one fraction, which was all negative.
Since each pack has 8 hot dogs and have 56 in total you use the equation p(8)=56 and just divide by 8 getting 7. They bought 7 packs of hot dogs.
The correct choice is 64 feet
Option a is correct. The calculated answer is 0.150
<h3>How to get the value using the cdf</h3>
In order to get P(0.5 ≤ X ≤ 1.5).
This can be rewritten as
p = 0.5
and P = 1.5
We have the equation as

This would be written as
1.5²/16 - 0.5²/16
= 0.1406 - 0.015625
= 0.124975
This is approximately 0.1250
