Answer:
option number 2 should be the answer if I'm wrong I'm mega sorry not that great at math. :>
Answer:
4.27%
Step-by-step explanation:
We have been given that college students average 8.6 hours of sleep per night with a standard deviation of 35 minutes. We are asked to find the probability of college students that sleep for more than 9.6 hours.
We will use z-score formula to solve our given problem.
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Before substituting our given values in z-score formula, we need to convert 35 minutes to hours.
Now, we need to find .
Using formula , we will get:
Using normal distribution table, we will get:
Therefore, 4.27% of college students sleep for more than 9.6 hours.
#1 m=7/4 the whole equation would be y=7/4x + 3/2
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
The slope of the line passing through two points can be found by using the formula
<h3>
</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question
The points are (-2,5) and (3/2, 2)
The slope is
<h3>
</h3>
We have the final answer as
<h3>
</h3>
