Answer:

(A) the exact count of siblings for each randomly chosen student

Step-by-step explanation:

Timothy aims to compute the average number of siblings per student in his institution

For this, he randomly sampled 75 students, documenting how many siblings they have

Afterward, he calculates the mean.

The mean is derived from the sampled group and not from all students, making options D and E incorrect.

Option A clearly reflects that the mean number of siblings pertains to the randomly sampled students.

A toy train moves along its track at a rate of 132 feet per minute. What is this rate in miles per hour?
tester [10823]

Answer:

1.5 miles per hour

Step-by-step explanation:

Multiply 132 feet by 60 seconds to get 7920. Subtract 5280, the number of feet in a mile, leaving you with 1 mile and an additional 2640 feet, which amounts to half a mile.

Sarah buys a new bike. The total cost of the bike including taxes is $349. She pays $100 down and then agrees to pay the balance
AnnZ [10993]

Each of the six payments amounts to $41.50

Step-by-step breakdown:

Given,

Total cost of the bike including taxes = $349

Initial payment = $100

Remaining balance = Total cost of bike - Initial payment

Remaining balance = 349 - 100

Remaining balance = $249

She opts to pay in six equal installments, so we divide the total remaining by 6.

Monthly payment = \frac{Amount\ left\ to\ pay}{No.\ of\ months}

Monthly payment = \frac{249}{6} = \$41.50

Each of the six payments amounts to $41.50

Answer:

At a confidence level of 90%, the margin of error is calculated to be 0.5133 grams.

Step-by-step explanation:

The formula for margin of error (E) is: (critical value × sample standard deviation) ÷ sqrt(n)

The sample standard deviation is 1.5 grams.

A 90% confidence level translates to 0.9.

Significance level is determined as 1 - C, which equals 1 - 0.9 resulting in 0.1 or 10%.

The sample size (n) is 25.

Degrees of freedom are calculated as n - 1, which is 25 - 1 equaling 24.

The critical value (t) for 24 degrees of freedom at a significance level of 10% is found to be 1.711.

Using these values, we calculate: E = (1.711 × 1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 grams.

A park ranger has 32 feet of fencing to fence four sides of a rectangular recycling site. What is the greatest area of recycling
Inessa [11212]
The maximum area that can be enclosed is 64 ft². To achieve the largest area while minimizing the perimeter, the dimensions should be as equal as possible. Allocating 32 feet of fencing for four sides gives us 8 feet per side, resulting in a square with a side length of 8; thus, the area equals 8*8 = 64.
