How many feet of chain fence are necessary to enclosed a dog pen that is square and has a area of 64 sq feet

Oliga [24]

Answer:

32 feet

Step-by-step explanation:

area of square is given by side^2

Perimeter of square is given by 4*side

_______________________________

Given

area of square = 64 sq feet

side^2 = 64

side^2 = 8^2

side = 8

thus side = 8 feet

_______________________________________

The dog pen is fenced with chain, hence chain will be fence at the edge of square and at the perimeter.

Thus, length of chain required will be same as the Perimeter of square.

Perimeter of given dog pen with side length 8 feet = 4*8 = 32 feet.

Thus, 32 feet of chain fence is required.

Construct the confidence interval for the population mean. c=. 95 x=6. 4 o=. 3 and n=42.

Damm [24]

The confidence interval is (63.909, 64.0907).

The confidence interval of a population mean is found using the formula:

CI = x ± z(σ/√n), where CI is the confidence interval, x is the mean, z is the z-score corresponding to the confidence level, σ is the standard deviation, and n is the population size.

In the question, we are given the confidence level, c = 95%.

Z-score corresponding to this, z = 1.96.

The mean of the population, x = 6.4.

The standard deviation of the population, σ = 0.3.

The population size, n = 42.

Thus, using the formula, the confidence interval is:

CI = 6.4 ± 1.96(0.3/√42),

or, CI = 6.4 ± 0.09073037.

Thus, the confidence interval is (64 - 0.09073037, 64 + 0.09073037), or, (63.909, 64.0907).

A supermarket needs to display 64 boxes of detergent.

Amiraneli [1.4K]

All the listed combination of row and boxes are correct and can be chosen from.

From the question, we are asked to find the row arrangement of a stack of boxes. Let us take a look at each one of the aforelisted answers

x rows with 16 boxes in each row
8 rows with x boxes in each row
16 rows with x boxes in each row

Since we are told that the total number of boxes to be stacked is 64, then for the first arrangement, we can deduce that the "x" is going to be 4. This is because multiplying 4 by 16 gives 64. For the second row, using the same calculation, we find that "x" is 8. And that of the third gives our "x" to be 4 as well. We can then adjudge that;

4 rows with 16 boxes in each row
8 rows with 8 boxes in each row
16 rows with 8 boxes in each row

Bearing this in mind, we can see that each of the 3 answers fits into the requirements we are asked.

At least 3 rows, and at least 4 boxes in each row.

Hence, all of the options are correct.

Use algebra tiles to find the difference. Let one yellow tile equal +1 and one red tile equal –1. 8 – (–6)

Sauron [17]

We draw 10 white tiles.

Then we shade in 9 of them.

We count the remaining tiles to get the answer, which is 1.
