Answer:

17 degrees

Step-by-step explanation:

So to find the answer you need to subtract. If the temp went down 22.1 degrees and it is -5.1 degrees you will subtract 22.1 - 5.1. This equals 17 degrees. You know the answer is correct because you can check your answer by adding: 5.1 + 17 = 22.1. We are disregarding the negative sign.

Kobotan [32]

He has $90 in total to spend

He spent (31/45) of this money on ticket

so money spent on ticket =(31/45) *90 =2790/45 =62

Now money left with him is 90-62 =28 $

Now it says that he spent (3/7) of this remaining money at concession stand

so money spent on concession stand =(3/7)*28 =84/7 =12

Answer:

A multiple regression equation for this model can be expressed as:

$y=b_0+b_1x_1+b_2x_2+b_3x_3$

Step-by-step explanation:

To model this problem as a multiple regression equation, we need to define which are the independent and dependent variables.

The dependent variable is the one which we want to predict for any set of independent variables values. This is the case of the driver's automotive insurance monthly premiums.

The driver's automotive insurance monthly premiums is the dependent variable "y".

The independent variables are the ones that explain the dependent variable variation. In this case there are: number of miles driven per week (x1); the age of the car, in years (x2); and the number of accidents in which the driver has been involved in the past 5 years (x3).

Then, a multiple regression equation for this model can be expressed as:

$y=b_0+b_1x_1+b_2x_2+b_3x_3$
