Answer:
438.3 ft^2
Step-by-step explanation:
find the fraction of the sector that you are finding the area of
360/165 simplify it instead of solving it leaving you with 24/11
use the equation: fraction of sector = pir^2
24/11 times pi(8)^2 = A of sector
24/11 times pi64 =
2.18 times 201.06 = 438.3 ft^2
3x-24=-6 . Add 24 to both sides, so that leaves you with 3x=18. Divide by 3 on both sides, and x=6
Answer is D.
Calculate the amount she earns per weak (32x20.29), then multiply by 52 to get what she earns in a year (649,28x52=33 762.56$). Then do a cross product (if that’s what it’s called in English) to determine how much of 33 762,36$ is 29,42%. It’ll give you 9 932, 95$ in taxes per year. Just substract that amount from the total of 33 762, 56$ and you get 23 829, 61$
Answer:
Step-by-step explanation:
For this case we have a sample of n =10 and we have the following statistics:
And we want to estimate the population variance. We need to remember that the population variance is given by this formula:
And the sample variance is given by:
And we can find a formula for the population variance in terms of the sample deviation like this:
And replacing we got:
Answer:
Stats. for a basketball game and the graph could be a bar graph or could be a line graph. And yes the data would look good on a graph.
