Answer:
0.180144 < p < 0.339856
Step-by-step explanation:
According to the Question,
- Given That, Out of 200 people sampled, 52 had kids, Thus the proportion of the mean is 52/200 = 0.26
⇒
standard error of the sample is square root(0.26 * (1-0.26) / 200) = 0.031
⇒alpha(a) = 1 - 99/100 = 0.01
⇒critical probability(p*) = 1 - a/2 = 0.995
⇒assuming a normal distribution, look for the z-score associated with 0.995 cumulative probability
, z-score = 2.576
⇒margin of error(ME) = 2.576 * 0.031 = 0.079856
-
the confidence interval is 0.26 + or - 0.079856
0.180144 < p < 0.339856
Answer: 4 cm and 11 cm.
Step-by-step explanation:
1. You can calculate the perimeter of a parallelogram as following:
Where a+b+c+d are the lenghts of the sides.
By definition the parallelogram has two pairs of parallel sides, therefore:
a=c and b=d
Then, you can calculate the perimeter as following:
2. Let's call the adjacent side 
, then the other side is 2x+3.
3. Substitute values and solve for x:
4. Then the lenghts of the sides are:
Answer:
B
Explanations
in this case the hypotenuse is 10,x is the adjacent side of the angle 37
therefore you have to use cos
cos37=x/10
x=7.9
=8
