Solution:

First, determine the porch's perimeter.

Using the formula:

Area of rectangle = Length × Width

Given that Bill's porch has an area of 50 square feet and the length is twice the width, let the width be x.

Then, length = 2x.

Plugging into the formula:

50 = x × 2x

50 = 2x²

x^{2} = \frac{50}{2}

x² = 25

x = \sqrt{25}

x = 5 feet, thus the width is 5 feet.

Length = 2 × 5 = 10 feet.

Using the perimeter formula:

Perimeter = 2 × (Length + Width)

Substitute the values:

Perimeter = 2 × (10 + 5) = 2 × 15 = 30 feet

Hence, the porch's perimeter is 30 feet.

Alan is conducting a survey to find out the type of art preferred by students in the town’s high school. Identify the population
Svet_ta [12734]

Response:

Alan's survey aims to determine the art preferences among students at the local high school.

To conduct a thorough investigation, he needs to consider all students in the school as the target population since that is his goal.

Nevertheless, in many cases involving statistical studies, it's impractical to include the entire population. In such instances, a sample that accurately reflects the overall student body is employed.

This sample is a subset of the population and must share the same characteristics and attributes; otherwise, the findings may be skewed.

Thus, a feasible sample would consist of a specific number of students from each grade level, including freshmen, sophomores, juniors, and seniors. This approach ensures the sample accurately represents the larger population.

For the month of June, Mae Green budgeted the following amounts: $180 for food, $475 for rent, $15 for transportation, $50 for i
tester [12383]
Question 1

Total budget sums up to 180 + 475 + 15 + 50 + 65 + 25 + 150 + 30 = $990.
Actual expenditure amounts to 182 + 475 + 12 + 65 + 68 + 12.50 + 150 + 36 = $1000.5.

Mae Green surpassed her designated budget.

---------------------------------------------------------------------------------------------------------

Question 2

Eleanor:
Earned = 380.48
Spent = 16.50

Peter:
Earned = 120 + 13.65 + 100 = 233.65.

Combined total income = 233.65 + 380.48 - 16.50 = 597.63.

-------------------------------------------------------------------------------------------------------------

Question 3

Aggregate expenditure = 540 + 48.55 + 34.15 + 12.80 + 18.95 + 38.60 + 2 + 6.50 = 701.55.

-------------------------------------------------------------------------------------------------------------

Question 4

Marie's updated balance = 250.65 - [21.95+48.50+75.60] + 55 = $159.50.

------------------------------------------------------------------------------------------------------------

Question 5

[235/825] × 100 = 28.48%
