Triangle abc is translated according to the rule (x, y) - (x + 2, y-8). if the coordinates of the pre-image of point b are
(4,-5), what are the coordinates of b'?
(2,3)
(1,-9)
(-3,-4)
(6.-13)

6,-13

Step-by-step explanation:

(4.-5)

4-2=6

-5-8=-13

Using the hypothesis test for one sample mean, There is NO SIGNIFICANT EVIDENCE to support the typist's claim

The test statistic :

T = (x - μ) ÷ (s/√(n))

T = (43 - 45) ÷ (15/√70)

T = - 2 ÷ 1.7928429

T = -1.12

At α = 0.05

Pvalue :

Degree of freedom, df = 70 - 1 = 69

Pvalue = 0.1333

Decision region :

Reject if Pvalue < α

0.1333 > 0.05

Since Pvalue > α We fail to reject the Null
