Answer:
I am 90% sure that the answer is M'N'O' is 90*
Step-by-step explanation:
A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?

<h3>What is statistical inference?</h3>
statistical inference uses sample data to make estimates of or draw conclusions about one or more characteristics of a population.
The purpose of statistical inference is to estimate this sample to sample variation or uncertainty. Understanding how much our results may differ if we did the study again, or how uncertain our findings are, allows us to take this uncertainty into account when drawing conclusions. It allows us to provide a plausible range of values for the true value of something in the population, such as the mean, or size of an effect, and it allows us to make statements about whether our study provides evidence to reject a hypothesis.
We have four ideas for using the statistical inference.
1. Estimating uncertainty.
2. Confidence intervals.
3. Hypothesis tests.
4. Connections with other material.

Answer:
37) m∠x = 5.25
39) m∠x = 0.5236 and m∠x = 2.62
Step-by-step explanation:
37)
∵ cotx = -0.6 and 3π/2 ≤ x ≤ 2π
∴ tanx = -1/0.6
∵ ∠ x in the fourth quadrant ⇒ ∴ m∠x = 2π - α where α is an acute angle
∵ tanα = 1/0.6 ⇒ α =
∴ α = 1.03038
∴ m∠x = 2π - 1.03038 = 5.25
39)
∵ cscx = 2 and 0 ≤ x ≤ 2π
∴ sinx = 1/2 ⇒ +ve value
∴ ∠x is in the first quadrant or the second quadrant
∴ m∠x = α or m∠x = π - α
∵ sinα = 1/2 ⇒ ∴ α =
∴ α = 0.5236
∴ m∠x = 0.5236
∴ m∠x = π - 0.5236 = 2.6216 ≅ 2.62
