Answer:

Regression equations can help you figure out if your data can be fit to an equation.This is extremely useful if you want to make predictions from your data- either future predictions or indications of past behavior.For example,you might want to know what your savings are going to be worth in the future.There are several types of regression equations,some of the more common include exponential and simoke linear regression.In elementary statistics,the regression equation you are most likely to come across is the linear form.

A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2 what is A’
Leviafan [203]

Answer:

point A' is (5, 9)

Step-by-step explanation:

A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2

A is (-2,-5)

a glide reflection wear the translation is (x,y) is (x+7,y)

7 is added with x, so add 7 with x  value -2 on A(-2,-5)

(-2+7, -5)

(5,-5)

Reflection is y=2

So we need to find the difference of y values of point (5,-5) and y = 2

2-(-5) = 7

So we move 7 units up from y = 2. y=2+7 = 9

x value remains the same x=5

Hence point A' is (5, 9)

The following problem describes procedures that are to be applied to numbers. Repeat the procedure for four numbers of your choi
mart [117]

Answer:

Conjecture: For every number x, the result of the is 2x

Step-by-step explanation:

First Number: 8

Multiply by 88: 88 * 8 = 704

Add 88: 704 + 88 = 792

Divide by 44: 792/44 = 18

Subtract 2: 18 - 2 = 16

Second: 10

Multiply by 88: 88 * 10 = 880

Add 88: 880+88=968

Divide by 44: 968/44=22

Subtract 2: 22-2=20

Third: 5

Multiply by 88: 88*5 = 440

Add 88: 440+88=528

Divide by 44: 528/44=12

Subtract 2: 12-2=10

Fourth: 2

Multiply by 88: 88*2=176

Add 88: 176+88=264

Divide by 44: 264/44=6

Subtract 2: 6-2=4

On a general terms:

Let the number be x.

Multiply by 88: 88x

Add 88: 88x + 88

Divide by 44: \frac{88x + 88}{44} = \frac{88x}{44} + \frac{88}{44} = 2x+2

Subtract 2: 2x + 2 - 2 = 2x

Notice that for every input x, the result is 2x

a number rounded to the nearest hundred thousand is 400,000. The same number rounded to the nearest ten thousand is 350,000. Wha
spayn [35]

Answer:

360000

Step-by-step explanation:

Well, we know the number must be above 350,000 because it was rounded up to 400,000. In order for the number to round down to 350,000 the number would have to be between 350,000-354999. So, the number could be any number in between those two numbers.

For example: The number COULD be 351,000 but, that is not the only possible answer.

but the answer would be 360000.
