we are given
radius is 1
we have angle as
now, we can use arc length formula
where
l is arc length
theta is angle
now, we can plug value
so,

You can surely do this! First, find the mean of the 8 given scores. Add up these scores and then divide the result (sum) by 8 to obtain the mean.
raw score - mean
The formula for "z-score" is z = -------------------------
std. deviation
You'll need to calculate the standard deviation of these 8 scores.
73 - mean
Then, as an example: raw score 73 translates into z-score z = ---------------
std. dev.
Answer:
Problem 4: x = -11
Problem 5: x = -7
Step-by-step explanation:
<u>Problem 4:</u>
x + 51 + 60 + 80 = 180
x + 51 + 60 + 80 - 51 - 60 - 80 = 180 - 51 - 60 - 80
x = -11
Answer: x = -11
<u>Problem 5: </u>
45 + 52 + x + 90 - 90 - 52 - 45 = 180 - 90 - 52 - 45
x = -7
Answer: x = -7
