<h2><u>Answer:</u></h2>

Goal = 45 (expected mean per week)

Ice creams sold each day = 54,45,33,39,48,40,21

Total Ice creams sold = 54+45+33+39+48+40+21 = 280

Total number of observations = 7

Mean = Total sum/total number of observation

= 280/7 (on simplification) = 40

Expected goal = 45

Mean of ice creams actually sold = 40

More ice creams to sell = Expected goal - Mean of ice creams actually sold

(on substituting the values)

= 45-40

Thus , the answer is option D , which is <em><u>5</u></em><em><u>.</u></em>

Patricia, Luca and Dauda shared an amount of money such that, Patricia had twice as much

inn [45]

Answer:

GH 1533

Step-by-step explanation:

Let Dauda's share of the money=x

Patricia had twice as much as Dauda, therefore:

Patricia's share=2x

Luca had GH 600.00 more than Dauda, therefore:

Luca's Share =x+600

If Patricia had GH 2,000.00

Then: 2x=2000

x=1000

Therefore:

Dauda's Share=GH 1000
Patricia's share=GH 2000
Luca's Share =1000+600=GH 1,600

Next, we determine the average share.

$\text{Average Share=}\dfrac{1000+2000+1600}{3}\\=\dfrac{4600}{3}\\\\=$GH 1533.33\\\text{Average Share} \approx $GH 1533 (to the nearest GH)$

Write the equation of a line that passes through the point (-1,5) and has a slope of -7 PLEASE ANSWER

DerKrebs [107]

Answer: Y = -7X-2

Step-by-step explanation:

if there are two co-ordinates (x1,y1) and (x2,y2).

If the line is passing through these co-ordinates

Then Slopw of the line = (y2-y1)/(x2-x1)

We have one co-ordinate (-1,5) let it be (X1,Y1)

Let second co-ordinate be (X,Y)

Slope = -7 = (Y-5) / (X-(-1))

-7 = (Y-5)/(X+1)

Y-5 = -7 (x+1)

Y-5 = -7x-7

ADDING 5 ON BOTH SIDES OF THE EQUATION

Y-5+5 = -7X-7+5

Y = -7x-2
