Answer:
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Step-by-step explanation:
Given;
Confidence interval CI = (a,b) = (0.036, 0.086)
Lower bound a = 0.036
Upper bound b = 0.086
To express in the form;
p-e< p < p+e
Where;
p = mean Proportion
and
e = margin of error
The mean p =( lower bound + higher bound)/2
p = (a+b)/2
Substituting the values;
p = (0.036+0.086)/2
Mean Proportion p = 0.061
The margin of error e = (b-a)/2
Substituting the given values;
e = (0.086-0.036)/2
e = 0.025
Re-writing in the stated form, with p = 0.061 and e = 0.025
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
(9 * 100) + (2 * 10) + (3 * 0.1) + (7 * 0.001) =
920.307
The median of grouped data is the middle number in an organized data set, so basically you need to organize all the numbers from lowest to greatest and find the middle number, which is 6.
Alright lets break it down:
Carol = 60 inches tall
Mindy = ??
Lets turn words into numbers:
60 inches is 20 inches less than (2x) Mindy's height
60 inches + 20 inches = 80 inches
This helps us visualize it better, if 60 is 20 inches less than two times Mindy's height, then that means 80 is two times Mindy's height, right?
80 ÷ 2 = 40 inches
Mindy's height is 40 inches
If this is still unclear, comment back.

The <em><u>correct answer</u></em> is:
Her variable expenses can be reduced.
Explanation:
In a household budget, you have fixed expenses and variable expenses.
Fixed expenses are expenses that are the same from month to month, such as a car payment, rent, power bill, etc. These cannot be reduced; if you were to pay less on your car payment, your car would be repossessed; paying less than you owe on the power bill can result in your power being disconnected; etc.
Variable expenses are expenses that are different from month to month, such as food, clothing, shopping, etc. If you are dealing with a situation where your wages are less than you anticipate, you can reduce items within your variable expenses to make sure you have enough money. For example, you can purchase fewer clothes that pay period or cut your grocery bill down.
