Answer:
$192
Step-by-step explanation:
Bill: $160.00
Tip: 20%
To figure out 10%, you need to move the decimal point over to the left one place: $16.00
10%: $16.00
16 times 2= $32.00
160.00+32.00= $192.00

the equation is in x-terms, meaning is a vertical parabola, and therefore the axis of symmetry will be the x-coordinate of the vertex, namely x = -1.
<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>
