Find the percentage of students that scored higher than 95.5. Round your answer to the nearest percent.

My name is Ann [436]

Answer:

$\% Change = \frac{9}{64} *100 = 14.0625\% \approx 14\%$

So then we have approximately 14% of the values higher than 95.5

Step-by-step explanation:

For this case we assume that the info is given on the figure attached.

From this figure we have the following frequencies for each class

Class Frequency

___________________________

70.5-75.5 13

75.5-80.5 7

80.5-85.5 6

85.5-90.5 10

90.5-95.5 19

95.5-100.5 9

____________________________

Total 64

So we have a total of 64 values and we want to find the percentage of students that scored higher than 95.5 so we can use the formula of relative change and we got:

$\% Change = \frac{9}{64} *100 = 14.0625\% \approx 14\%$

So then we have approximately 14% of the values higher than 95.5

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

$y=0.5x+125$
