Answer:

A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. In this case we use multiplication and division.

Step-by-step explanation:

Multiplication: 9 x 5 is 45

Same as 5 x 9 is 45

Division: 45 ÷5 is 9

Same as 45÷9 is 5

Hope this helps :)

Suppose you performed a regression analysis. The mse for this scenario is 0.105

Regression is a statistical method used in finance, making an investment, and different disciplines that attempt to determine the electricity and man or woman of the relationship between one established variable (commonly denoted through Y) and a sequence of different variables (called independent variables).

We are able to say that age and peak can be described through the usage of a linear regression version. because someone's peak will increase as age will increase, they have got a linear courting. Regression fashions are commonly used as statistical proof of claims regarding regular statistics.

"Regression" comes from "regress" which in turn comes from Latin "regresses" - to head returned (to something). In that feel, regression is the approach that permits "to head again" from messy, hard-to-interpret data, to a clearer and more significant version.

1 1.1 0.01

1.5 1.3 0.04

2.8 3.2 0.16

3.7 3.7 0

The error sum of the square is given by

ESS = (y- )

ESS=0.21

The mean square error is given by

ESS MSE = ESS/dfe

MSE = \frac{0.21}{2}

MSE = 0.105

Can someone please help me with this question ASAP
Lana71 [14]

Answer:

  • x - 7.31 ≤ 10
  • x ≤ 17.31

Step-by-step explanation:

let x = the amount of money in the second piggy back

We assume that the second piggy bank has MORE than the piggy bank with $7.31 in it:

x - 7.31 ≤ 10

<u>Solution</u>

Add 7.31 to both sides:  x - 7.31 + 7.31 ≤ 10 + 7.31

                                                       ⇒ x ≤ 17.31

Frieda worked 26 hours 13 minutes last week. She earns $18.75 per hour. What is Frieda's pay for this work period? Round your an
Leya [2.2K]

Answer:

$491.56

Step-by-step explanation:

Total number of hours worked by Frieda = 26 hours 13 minutes

lets convert 13 minutes to hour

60 minutes = 1 hour\

1 minutes = 1/60 hours

13 minutes = 13/60 hours

Thus,

Total number of hours worked by Frieda = (26 + 13/60) hours

In 1 hours Freida earns =  $18.75

in  (26 + 13/60) hours Frieda earns =  $18.75((26 + 13/60)) = 487.5 + 4.06

in  (26 + 13/60) hours Frieda earns = $491.56  (Answer)
