A group of people in an art class and a crafts class were surveyed whether they exercise more than 5 hours a week or less than 5

hours a week. In the art class, 5 people exercise more than 5 hours a week and 8 people exercise less than 5 hours a week. In the crafts class, 10 people exercise more than 5 hours a week and 4 people exercise less than 5 hours a week.
What is the relative frequency of people who exercise more than 5 hours a week in the art class to the total number of people surveyed?

The Relative Frequency is how often something happens out of all possible outcomes. Here you have numbers -- Arts - 5 more, 8 less Crafts- 10 more, 4 less ------------------- What is the relative frequency of people who exercise more than 5 hours a week in Arts class? There are 5 people in arts that exercise more than 5 hours/week. The total number of people all together surveyed is 5 + 8 + 10 + 4 = 27 people There are 5 out of 27 people that are in this catagory Relative Frequency = 5/27 = 0.19

Find the x-values that are solutions of the equation 5cot^2x-15=0
julia-pushkina [17]
First solve for the trig function 'cot'
cot^2 x = \frac{15}{5} = 3

Next take the sqrt of both sides (include plus/minus)
cot x = \pm \sqrt{3}

Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)

tan x = \pm \frac{1}{\sqrt{3}} = \pm \frac{\sqrt{3}}{3}

Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.

x = \frac{\pi}{6}, \frac{5\pi}{6}, \frac{7\pi}{6}, \frac{11\pi}{6}

Wouldn’t it just be 94 degrees? please help
nataly862011 [7]

We know that the m<RTV = 65°.

If we know that the m<UTV = 29°, we can simply

subtract the m<UTV from the m<RTV to get the answer.

So we have 65 - 29 or 36°.
