A sample of 200 college freshmen was asked how many hours per week they spent playing video games. The following frequency distr

JulsSmile [24]

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:

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

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

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

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

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

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

1. What does the mark of the angles and sides of the triangle indicate?

RideAnS [48]

2. You see them in your face:

$\displaystyle m∠F ≅ m∠C;$ $\overline{FD}$ ≅ $\overline{CA}$

$m∠E ≅ m∠B;$ $\overline{FE}$ ≅ $\overline{CB}$

$m∠D ≅ m∠A;$ $\overline{ED}$ ≅ $\overline{BA}$

To sum up, <em>corresponding parts of congruent triangles are always congruent</em> [<em>CPCTC</em>].

1. The edge and angle markings of both triangles represent all corresponding parts. Each angle and edge corresponds with another angle and edge.

I am joyous to assist you at any time.
