Answer: (0.8115, 0.8645)
Step-by-step explanation:
Let p be the proportion of people who leave one space after a period.
Given: Sample size : n= 525
Number of people responded that they leave one space. =440
i.e. sample proportion: 
z-score for 90% confidence level : 1.645
Formula to find the confidence interval :


Hence, a 90% confidence interval for the proportion of people who leave one space after a period: (0.8115, 0.8645)
Parallelogram so
CD = AB
18x - 5 = 15x + 4
3x = 9
x = 3
answer
x = 3
Answer:
the answer is 3 raised ro the third power
the exact value of 0.428x2.75 is 1.177, in order to get this you multiply both number with each other.
Answer: 99 square cm
Step-by-step explanation:
you cut the height in half, so 6 divided by 2 = 3, if you do that you have to do the same to the width, so again 6 divided by 2 = 3, the length stays the same, so the equation would be 3 X 3 X 11 = 99
