Answer:
Step-by-step explanation:
N(106,14²)
(calculated using excel, let me know if you were supposed to use a normal table) = 0.4715
85.34
Q1:96.56
Q3:115.44
IQR (which is Q3-Q1)= 115.44-96.56= 18.88
The dilation factor Sophia is using appears to be
(image coordinate)/(original coordinate) = -9/-3 = 15/5 = 3
Then the problem tells us
(pre-image point)×3 = (3, 1)
so we conclude
(pre-image point) = (3, 1)/3 = (1, 1/3)
Answer:
76
Step-by-step explanation:
4(-4(-9)-17)
4(36-17)
4(19)
Answer:
Its the second one
Step-by-step explanation
the reason why is because
<= less than- so it goes to the left and since its not less than or equal to its an open circle instead of a closed circle.
