Answer:
The 90% CI for p is (0.53, 0.83)
Step-by-step explanation:
We have to develop a 90% confidence interval for the proportion of all students at the college that have met with a counselor to develop an educational plan.
We have a sample of size 25, where the sample proportion is:
The critical value of z for a 90% CI is z=1.645.
The margin of error is then:
Then, the lower and upper bound of the confidence interval are:
The 90% CI for p is (0.53, 0.83)
Answer:
2x^2
Step-by-step explanation:
hope this helps :)
When the 10 is to a negative power you move the decimal to the left. in this case its 5 spots. i believe your answer is .00005003
The picture in the attached figure
Part 1) <span>
What is the total area of the swimming pool?</span>
we know that
<span>area of the swimming pool=area rectangle-area semi circle
area rectangle=20*36-----> 720 ft</span>²
area semicircle=pi*r²/2
r=18/2----> 9 ft
area semicircle=pi*9²/2----> 127.17 ft²
area of the swimming pool=720 ft²-127.17 ft²----> 592.83 ft²
the answer Part 1) isThe area of the swimming pool is 592.83 ft²Part 2) <span>What is the perimeter of the swimming pool?
</span>
perimeter of the swimming pool=perimeter of rectangle-18 ft+perimeter semi circle
perimeter of rectangle=2*[20+36]---> 112 ft
perimeter semi circle=2*pi*r/2----> pi*r
r=9 ft
perimeter semi circle=pi*9----> 28.26 ft
so
perimeter of the swimming pool=112 ft-18 ft+28.26 ft----> 122.26 ft
the answer Part 2) is122.26 ft
