Hello here is a solution :
<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
<h2>= 5</h2>
Thus , the answer is option D , which is <em><u>5</u></em><em><u>.</u></em>
If we are given function f(x) vertical translation is done by adding number to end of formula for translation to up or substracting number for translation to down.
f(x) + a OR f(x) - a
Horizontal translation is done by adding number next to x variable for translation to left or substracting number for translation to right.
f(x+a) OR f(x-a)
We need to translate function <span>5 units to the left and 4 units up. That means that we need to add 5 next to x and add 4 to end of function. The result is:
