Answer:

$\% Below\ 50 = 88 \%$

$\% 43\ or\ more = 17 \%$

Step-by-step explanation:

Given

$Total = 200$

<em>The attachment presents the table properly</em>

Solving (a): Percentage of those who play for less than 50 hours weekly

To do this, we simply consider the frequency of students that fall within:

1.0 - 7.9, 8.0 - 14.9,......,43.0 - 49.9

Their frequency is:

$Frequency = 21 + 37 + 40 + 27 + 23 + 18 + 10$

$Frequency = 176$

The percentage is then calculated as:

$\% Below\ 50 = \frac{Frequency}{Total} * 100\%$

$\% Below\ 50 = \frac{176}{200} * 100\%$

$\% Below\ 50 = \frac{176* 100}{200} \%$

$\% Below\ 50 = \frac{176* 1}{2} \%$

$\% Below\ 50 = \frac{176}{2} \%$

$\% Below\ 50 = 88 \%$

Solving (b): Percentage of those who play for 43 or more hours weekly

To do this, we simply consider the frequency of students that fall within:

43.0 - 49.9,......,64.0 - 70.9

Their frequency is:

$Frequency = 10 + 7 + 5+12$

$Frequency = 34$

The percentage is then calculated as:

$\% 43\ or\ more = \frac{Frequency}{Total} * 100\%$

$\% 43\ or\ more = \frac{34}{200} * 100\%$

$\% 43\ or\ more = \frac{34* 100}{200} \%$

$\% 43\ or\ more = \frac{34* 1}{2} \%$

$\% 43\ or\ more = \frac{34}{2} \%$

$\% 43\ or\ more = 17 \%$

Sarah is solving the equation -7/8x=24

ExtremeBDS [4]

the answer would be -21 because you would have to multiply the 24 by -7 because it is dividing on the other side. and then you would have to divide the number you get by 8

so basically, it will look like this step by step:

-7/8x=24

8x=24*-7

8x=-168

x=-168/8

x= -21
