Answer:
<u>The correct answer is D. 69</u>
Step-by-step explanation:
Let's recall that if an exterior angle has its vertex where two rays share an endpoint outside a circle, the measure of that exterior angle is found by dividing the difference between the measures of the intercepted arcs by two.
Therefore, we have:
x = (Measure of arch CD - Measure of arch BD)/2
Replacing with the real values:
x = (210 - 72)/2
x = 138/2 = 69°
<u>The correct answer is D. 69</u>
False.
To determine the standard deviation (and the same is true for the mean) you need to know how many times each number was repeated.
It is the first one for sure! Hope this helps
9/25=
25*4=100 so,9*4=36
9/25=36%
Y = kx
Y is the total cost
The number of dvds is x
The cost of each one ($12) is k
y = $12x
Or instead of Y you can but T for total cost
t = $12x
