divide each side by -5
-5m/-5 = -40/-5
m = 5
Answer:
3.8
Step-by-step explanation:
Hey! Let's start by assuming that these are all normal courses, and that <u>GPA is given by the following scale:</u>
A - 4.0
B - 3.0
C - 2.0
D - 1.0
F - 0.0
That said, this question really just involves calculating the averages.
To find the average, we add all the values together and divide the sum by the total number of values.
<u>Therefore, our expression would look like:</u>
(4.0 + 4.0 + 4.0 + 4.0 + 3.0)/5
This is because there are 5 total values.
Simplify:
19/5
3.8
This means your GPA would be 3.8
We are looking to find P(X>60 students)
X is normally distributed with mean 50 and standard deviation 5
We need to find the z-score of 60 students
To find the probability of P(Z>2), we can do 1 - P(Z<2)
So we read the probability when Z<2 which is 0.9772, then subtract from one we get 0.0228
The number of students that has score more than 60 is 0.0228 x 1000 = 228 students
96° i think
correct me if im wrong 。^‿^。
