How many fewer models made by himself were donated than those he bought is 72

First step is to calculate the models that was made by Jack

Jack Models =360 × 40%

Jack Models= 144

Second step is to calculate the models that was bought by Jack

Models  bought= 360 – 144

Models  bought= 216

Third step is to calculate the amount of models made donated by  of Jack

Models donated=144 × 25%

Models donated = 36

Fourth step is to calculate the amount of models bought by Jack  donated

Models donated=216 × 50%

Models donated= 108

Now let determine the how many fewer models made by himself were donated than those he bought

Fewer models made=108 – 36

Fewer models made= 72

Inconclusion How many fewer models made by himself were donated than those he bought is 72

To investigate the relationship between amount of sales y (in thousands of dollars) and the amount x (in hundreds of dollars) sp
riadik2000 [5.3K]

Answer:

(A) For each additional hundred dollars spent on advertising, sales are predicted to increase by $2,380.

Step-by-step explanation:

Regression isa statistical equation, denoting relationship between independent (causal) variable(s) & dependent (effected) variable.

y = a <u>+</u> bx

where y = dependent variable, x = dependent variable, a (intercept) = autonomous value of y, b (slope) = change in y due to change in x

Regression equation of independent variable (x) as advertising expenditure & dependent variable (y) sales : y = 24.45 + 2.38x

Sales are in thousands of dollars, advertising expenditure is in hundreds of dollars. So, the interpretations are :

  • Intercept interpretation : When there is zero advertising expenditure, sales are 24.45 thousands i.e $24450
  • Slope Interpretation :<u> When advertisement expenditure change (rise) by 1 hundred, sales change (rise) by 2.38 thousand i.e</u><u> </u><u>$2380</u>

What is the slope of the line passing through(-7, 8) (-8, 8) is?
Hunter-Best [27]

Answer:

Step-by-step explanation:

(-7, 8) (-8, 8)

(y2 - y1) / (x2 - x1)

(8 - 8) / (-8 + 7)

0 / -1

the slope is 0

you could also see this because the y value doesn't change

if the y value doesn't change the slope is 0, if the x value doesn't change the slope is undefined

What is quartile 1 (Q1)quartile 3 (Q3) and the IQR? Answer all three parts . 13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50
Fittoniya [83]

Answer:

Quartile 1 (Q1) = 24

Quartile 2 (Q2) = 47

IQR = 23

Step-by-step explanation:

Given:

The set of data are:

13, 23, 24, 25, 26, <u>26</u>, 37, 47, 47, 48, 50

The data are in increasing order. The number terms are, n = 11.

Therefore, the middle term = \frac{n+1}{2}=\frac{11+1}{2}=6^{th}\ term

So, the median = 26

Now, the median divides the set of data into two parts. The median of first part is the quartile 1 and the median of second part is quartile 2.

So, the first part has the following terms:

13, 23, <u>24</u>, 25, 26

Here also, n=5. So, the third term is the median.

∴ Q1 = 24

The second part has the following terms:

37, 47, <u>47</u>, 48, 50

Here also, n=5. So, the third term is the median.

∴ Q2 = 47.

Now, IQR = Q2 - Q1 = 47 - 24 = 23.
