Answer 1

Answer:

Answer:

Yes this is true.

Step-by-step explanation:

In a survey of a sample of computer users, 10% said their computer had a malfunction that needed to be repaired by a service technician.

The number 10% is a statistic because it is based on a sample of say x computer users, not the entire population of computer users.

And sample x can be any number like 500 or 600 etc. The entire population is in millions. And, sample is a part of population.

So, the answer is true.

Answer 2

Answer: im fairly certain that its true because you don't know the exact number of people surveyed. If they had said "out of the 100 people we surveyed 10% had problems" that would be a Parameter because parameters are percents out of the whole. if that makes sense.

It hinders the normalcy of the way of living for the individual having such disorder. Common ailments are depression, anxiety, eating disorders, addiction, and schizophrenia.

One of the reasons why people turn mentally ill is because of his exposure to stimuli and the world around him. Others are purely genetic.

A beach has to enclose a rectangular area, because some endangered species are nesting there. They have 200 feet of rope to rope off the area with. What is the maximum area that they can rope off?

Answers

Area is equal to length times width. The perimeter (the amount of rope) has to equal twice the length added to twice the width so we're left with:
A = l * w
200 = 2l + 2w
solve for either l or w
l = 100 - w
plug into the area equation to get one equation with two variables
A = w(100 - w)
A = -w^2 + 100w
take the derivative
A' = -2w + 100
set the derivative equal to zero
0 = -2w + 100
2w = 100
w = 50
This is the width that maximizes the area
with a width of 50, the length must also be 50 to have a perimeter of 200
therefore, they can rope up to 50 * 50 = 2500 ft^2

Final answer:

The maximum area that can be roped off with 200 feet of rope is 2500 square feet by making the roped off area a square.

Explanation:

The question deals with the optimization of area given a fixed perimeter, which involves the principles of geometry and algebra. Since the area needs to be roped off is a rectangle, and you have 200 feet of rope, your rectangle will have dimensions length (L) and width (W) such that 2L + 2W = 200.

To maximize the area of a rectangle given a fixed perimeter, the rectangle should be a square. So, for a maximum area, the length and width should be equal. Thus, each dimension (length and width) would be 200/4 = 50 feet.

Finally, to find the maximum area, we multiply the length by the width: 50 feet * 50 feet = 2500 square feet. So, the maximum area that they can rope off with 200 feet of rope is 2500 square feet.

the refreshment stand at the fair was open for 3 hours four people took turns working at the stand for the same amount of time how many minutes did each person work

Answers

first off, simplify 3 hours. One hour is equal to 60 minutes, so we get 180 minutes. Next we divide 180 by four. We can make this easier by dividing 180 by ten, and multiplying it by 10 after we do everything. 4 times 4 is 16, and then the remaining 2 divided by 4 is .5. We have 4.5, but now we need to multiply 4.5 by 10, and we get 45. The answer is 45.

What is pi divided by 2/3?

Answers

Given:
pi is equal to 3.14

3.14 ÷ 2/3

Rules in dividing fractions.
3.14 is the 1st fraction. It has a denominator of 1. 3.14/1
2/3 is the 2nd fraction

1) get the reciprocal of the 2nd fraction.
2/3 ⇒ 3/2

2) multiply the 1st fraction to the reciprocal of the 2nd fraction
3.14 * 3/2 = (3.14*3) / 2 = 9.42 / 2 = 4.71

Pi divided by 2/3 is 4.71

π ÷ 2/3

= π × 3/2 = 3π/2 = 1.5π: π ≈ 3.142

1.5π ≈ 1.5 × 3.142 ≈ 4.713

π ÷ 2/3 ≈ 4.713
