Answer:
a) Option C) The score was 2.49 standard deviations higher than the mean score in the class.
b) 2.3%
Step-by-step explanation:
a) We are given that the distribution of test grades is a bell shaped distribution that is a normal distribution.
Formula:
Option C) The score was 2.49 standard deviations higher than the mean score in the class.
b) The z-score for a particular score is -2.
We have to evaluate
P(z < -2)
Calculating the value from normal z-table.
Thus, 2.3% of of the class scored lower than my friend.
Answer:
Step-by-step explanation:
if she uses 16, you divide that by 4 which is 4/1. therefore, when you remove 4 (3)= 12 out of the 16, you are left with 4 gallons of gas

Step-by-step explanation:
(p.s this is just what I got from this so im not 100 percent sure)
Answer:
3, -1
6,-4
IDK about the third vertices, you didn't give the original coordinates!
Step-by-step explanation:
180 degree rotation= (x,y) to (-x,-y)
3,1 goes to -3,-1
6,4 goes to -6, -4
IDK about the third vertice, you didn't mention it.
Reflection over y-axis= (x,y) to (-x,y)
-3, -1 goes to 3, -1
-6,-4 goes to 6,-4
hope this helps!
