Answer:
D. 7.29.
Step-by-step explanation:
For a Normal Distribution:
Q1 = mean - (0.675) * standard deviation
= 8.5 - 0.675*1.8
= 7.285.
Answer:
y = -x
Step-by-step explanation:
it because the reflection change the value of x become -y
so the reflection we can use is the line y = -x
Y = mx + c
gradient = -6-9/-8-4
= -15/-12
= 1.2
when x = 4 and y = 9,
9 = 1.2(4) + c
c = 9 - 4.8
= 4.2
The slope of the line is y = 1.2x + 4.2 .
