At one point in a Girl Scout cookie sales drive, region C had sold 1500 boxes of cookies, and region D had sold 1200 boxes of co

juin [17]

Answer:

a)After 6 days region D will catch region C

b) Region C will sell 13500 cookies and region D will sell 13600 cookies

Step-by-step explanation:

a) Cookies sold by region C more than region D= 1500-1200=300

But region D can sells 50 cookies every day i-e

50 cookies = 1 day

==> 1 cookie= 1÷50

==> 300cookies = 300÷50=6 days

So, after 6 days region D will catch up region C's

b) If sale stopped after 8 days;

Then sale of region C for 8 days = 1500×8=12000 cookies

so , total cookies sold = 1500 +12000=13500

For region D;

Before catching up region C cookies sold by region D = 1200

Till catching up region C - region D had also sold 1500 cookies,

and for 50 extra cookies than region C

next 8 days region D will sale =(1500+50)×8=1550×8=12400 cookies

So, total number of cookies sold by region D = 1200+12400=13600

Use a graphing calculator to find the value of the correlation coefficient r and determine if there is a strong correlation amon

Natali [406]

The value of the correlation is -0.0721 and it is a weak negative correlation

<h3>How to determine the correlation coefficient?</h3>

The points are given as:

(12, 28), (15, 50), (18, 14), (21, 28), (24, 36)

Enter the above points in a graphing calculator.

From the graphing calculator, we have the following summary:

<u>X Values</u>

Sum X = 90
Mean = 18
∑(X - Mx)^2 = SSx = 90

<u>Y Values</u>

Sum Y = 156
Mean = 31.2
∑(Y - My)^2 = SSy = 692.8

<u>X and Y Combined</u>

N = 5
∑(X - Mx)(Y - My) = -18

<u>R Calculation</u>

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

This gives

r = -18 / √((90)(692.8)) = -0.0721

So, the correlation coefficient is -0.0721

The above is a negative correlation because it is less than 0 and it is a weak correlation because it is closer to 0 than -1

Hence, the correlation is a weak negative correlation

Mr. Gaster has $5 in his piggy bank and wants to put $45 every week into the piggy bank. Make you equation showing how much mone

Romashka-Z-Leto [24]

So your starting amount is 5. Your equation will start like this:
5+
Now 45 dollars a week. So no matter how many weeks you are going to multiply it by 45. So you add that in and you have an equation that looks like this:
5+45x
X stands for the weeks. Then finish it off with your equals:
5+45x=y
Y is the total amount of money.
The Equation will be.
5+45x=y

Part 2:

The equation is set up on weeks so you need to find out how many weeks 28 days is.
28/7=4

Now that you know that you can substitute 4 for x.

5+45*4=y
5+180=y
185=y
He will have 185 dollars in his bank. <span />
