Answer:

Lower quartile: 72

Upper quartile: 84

Step-by-step explanation:

Follow the instructions in the hint to solve the problem.

First, divide the data set into halves:

70, 70, 72, 75, 79

80, 80, 84, 89, 95

Now, find the median of the two sets. The median of set #1 is 72, as that is the number in the middle of the data.

The median of set #2 is 84 for the same reason.

Upper and lower quartiles are just different words for upper and lower medians. The upper quartile is the higher number, and the lower quartile is the lower number.

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site

tatiyna

Answer:

54.6 hours

Step-by-step explanation:

65x2 is 130 130-950 is 820 then 820 divided by 15 is 54.6 therefore meaning you have to work 54.6 hours to get 950$ you can check this by doing 54.6x15+130, might not be exact because i rounded to the nearest tenth.

Hope this helps!

Consider angle θ in Quadrant II, where sinθ = 4/5 . What is the value of cosθ?

Kay [80]

Answer:

3/5

Step-by-step explanation:

sin theta=opposite/hypotenuse

4/5=opposite/hypotenuse

therefore opposite=4 and hypotenuse=5

for adjacent

using pythagoras theorem

a^2+b^2=c^2

opposite^2 + adjacent^2 =hypotenuse^2

4^2 + adjacent^2 =5^2

16 + adjacent^2 =25

adjacent^2 =25-16

adjacent = $\sqrt{9$

adjacent=3

cos theta=adjacent/hypotenuse

=3/5

therefore the value of cos theta is 3/5
