Answer:
The coordinates are
A(-4,-3) →A'(-1, -1)
B(-1, 1) → B'(2, 3)
C(3, 5) → C'(6, 7)
D(2,-5) → D'(5,-3)
Step-by-step explanation:
Given the graph of figure whose coordinates are
A(-4, -3), B(-1, 1), C(3, 5), D(2, -5)
We have to find the coordinates of the image after a translation using T(x, y) → (x + 3, y + 2).
Coordinates after translation are
A(-4,-3) → A'(-4+3, -3+2)=A'(-1, -1)
B(-1, 1) → B'(-1+3, 1+2)=B'(2, 3)
C(3, 5) → C'(3+3, 5+2)=C'(6, 7)
D(2,-5) → D'(2+3, -5+2)=D'(5,-3)
which are required coordinates of the image after a translation of the figure below using (x, y) → (x + 3, y + 2).

Answer:
z = -1.645
Step-by-step explanation:
b) n =25, M = 4.01 , \mu = 4.22 , \sigma = 0.60 , \alpha= 0.05
The hypothesis are given by,
H0 : \mu\geq 4.22 v/s H1 : \mu < 4.22
The test statistic is given by,
Check attachment for the formula that should br here.
z = \frac{4.01- 4.22 }{0.60 /\sqrt{25}}
= -1.75
The critical value of z = -1.645
The calculated value z > The critical value of z
Hence we reject null hypothesis.
