Option A is correct.

For testing, if x is a significant predictor of y in simple linear regression, we need to determine if the <u>slope </u><u>is </u><u>significantly different </u><u>from</u><u> zero</u>.

What is linear regression?

A statistical technique known as linear regression is used to represent the connection between a scalar answer and one or more explanatory factors. When there is just one explanatory variable, simple linear regression is employed; when there are numerous explanatory variables, multiple linear regression is utilized.

Based on the value of another variable, linear regression analysis makes predictions about the value of the first variable. The dependent variable is the one you're trying to forecast. The independent variable is the one you are utilizing to make a prediction about the value of the other variable.

Find the LCM and HCF of 64 and 72 using prime factors​
Nadya [2.5K]

What is the LCM of 64 and 72?

Find the prime factorization of 64.

Find the prime factorization of 72. 72 = 2 × 2 × 2 × 3 × 3.

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3.

LCM = 576.

What is the GCF of 64 and 72?

Find the prime factorization of 64. 64 = 2 × 2 × 2 × 2 × 2 × 2.

Find the prime factorization of 72. 72 = 2 × 2 × 2 × 3 × 3.

To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 2 × 2 × 2.

GCF = 8.

What multiplication fact Can be found by using the Arrays for 2 times 9 and 5 times 9
serg [7]
An array is a visual drawing to be used in multiplication problems. For example; 1 × 2 is 2 and you draw it or visualize it like; 00
So the answer to your question would be...
000000000
000000000

000000000
000000000
000000000
000000000
000000000
000000000
000000000

The top is the array of how it would look like to your answer tour question. Also, another way to do this is (2 + 5) × 9 = 63 
And yasss your answer is 63.... ALSO

***!!! PLEASE give this a THANKS! ALSO the BRAINIEST ANSWER/QUESTION! :) :D =P =) =D

If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'
Sever21 [200]

Answer:

Step-by-step explanation:

Reflection across the y axis changes the x value.

Reflection across the x axis changes the y value.

This is counterintuitive, but it is correct.

A'

(-1,6)

B'

(-2,1)

C'

(-5,2)

Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction
