A manager wishes to determine the relationship between the number of miles traveled (in hundreds of miles) by her sales repres

kati45 [8]

Answer:

$y=3.53 x +37.92$

And for 0 miles if we use the model we got:

$y(0)= 3.53*0 +37.92 = 37.92$

But for this case. No is not reasonable for a representative to travel o miles and have a positive amount of sales.

Step-by-step explanation:

For this case we assume the following data:

Miles traveled (X): 2,3,10,7,8,15,3,1,11

Sales (Y): 31,33,78,62,65,61,48,55,120

We want to found a linear model like this one : $y = mx+b$ . Where:

$m=\frac{S_{xy}}{S_{xx}}$

Where:

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}$

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}$

With these we can find the sums:

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}=582-\frac{60^2}{9}=182$

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}=4329-\frac{60*553}{9}=642.33$

And the slope would be:

$m=\frac{642.33}{182}=3.529$

Nowe we can find the means for x and y like this:

$\bar x= \frac{\sum x_i}{n}=\frac{60}{9}=6.667$

$\bar y= \frac{\sum y_i}{n}=\frac{553}{9}=61.444$

And we can find the intercept using this:

$b=\bar y -m \bar x=61.444-(3.529*6.667)=37.917$

So the line would be given by:

$y=3.53 x +37.92$

And for 0 miles if we use the model we got:

$y(0)= 3.53*0 +37.92 = 37.92$

But for this case. No is not reasonable for a representative to travel o miles and have a positive amount of sales.

D = 6 when v = 20 Work out an equation connecting d and v work out the value of d when v =30

Grace [21]

The value of d is 27/2 when v =30

<h3>What is equation?</h3>

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal

Suppose that d is directly proportional to the square of v.

So the equation is, d ∝ v² equals to d = kv², where k is a constant.

So in order to find the value of k,

d = k v²

d = 6, v = 20,

Substitue the value of d and v into the equation :

6 = k(20)²

k = 6/400

k = 3/200

Substitue the value of k and v =30 into the equation,

d = 3/200(30)²

d = 2700/200

d = 27/2

Hence, the value of d is 27/2 when v =30

Ms. Turner drove 825 miles in March. She drove 3 times as many miles in March as she did in January. She drove 4 times as many m

Papessa [141]

1100 miles
this is because u first have to find the miles she drove in january. since she drove 3 times as much in march than in january, u divide or 825 divided by 3 to get 275. since she drove 4 times as much in february of january, u multiply 275 by 4 to get 1100.

hope this helps! :)

Convert:4 gal= qt what is it

fgiga [73]

Answer:

4 gallon = 16 quarts

Step-by-step explanation:

Consider the provided information.

We need to convert gal into qt

We know that 1 gallon = 4 quarts

Now in the given question, we have 4 gal.

Multiply both the sides by 4

1×4 gallon = 4×4 quarts

4 gallon = 16 quarts

Hence, 4 gallon is equal to 16 quarts.
