We are given a triangle on the graph.
The vertices of the given triangle are (1,3), (-3,4) and (5,5).
The shown triangle is being transformed by the following rule
(x, y)→(x+3, y−2).
Let us apply same rule in each of the above coordinate
(1,3) →(1+3, 3 -2) → ( 4,1)
(-3,4) →(-3+3, 4 -2) → ( 0, 2)
(5,5) →(5+3, 5 -2) → ( 8, 3).
<h3>Therefore, coordinates of the transformed triangle are (4,1), (0,2) and (8,3).</h3>

Answer:
A. n = 22
Step-by-step explanation:
Hello!
The researcher conducted a one-sample t-tas with the following hypotheses:
H₀: μ = μ₀
H₁: μ ≠ μ₀
α:0.05
The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail. ±
If α:0.05 then α/2:0.025 and 1-α/2= 0.975
Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975
For n = 22
For n= 21
For n= 20
The correct answer is a) n= 22
