It’s 4 3/2! Divide and then simplify! :)
Answer:
Step-by-step explanation:
look, area = length x width
so that means that the area of this rectangle is
= 11 1/2 * 8
= 23/2 * 8
= 23 * 4 (simplified)
= 92 in^2
B! because X can represent any number, and your number(unknown) will be shown as X and for it to be in between both -3 and 3 it has to be less than (shown as >) 3 or greater than (shown as <) -3.
The interior angles of a hexagon should be equal to 720°. So, to find x, add up all of the other angles and subtract them from 720.
The other angles = 596°
720 - 596 = 124
So, x = 124°.
Answer: (54.13%, 53.83%)
Step-by-step explanation:
Confidence interval for population proportion is given by :-

= sample proportion
n= sample size.
z* = critical z-value.
Let p be the proportion of individuals supportive of a new public works project.
As per given , we have
n= 258

For 99.9% confidence , significance level α= 0.001
Critical z-value for 99.9% confidence interval =
[By z-table]
Then, the 99.9% confidence interval for the support level percentage in the entire city will be :

Hence, the 99.9% confidence interval for the support level percentage in the entire city is (54.13%, 53.83%) .
