Of all the people at a community swimming pool, 54 are in the water and 66 are not in the water. What percentage of the people at the pool are in the water?

10%

45%

82%

55%

Answers

Answer 1

Answer: 45%.

Step-by-step explanation: When you solve problems like these, you need to make the total 100%.  The total amount of people at the community pool is 120.  120 can be our 100%.  66 people aren't in the water and 54 are in the water.  As you can see, less than half of the total number of people at the community swimming pool is in the water, which means that is 45%.  The 66 people who aren't in the water are 55% of the total people that are at the community swimming pool.  So in summary, 45% of the total people who are in the community swimming pool are in the water.

Have a great day! :)

Answer 2
The percentage of people at the pool and in the water is a representation of the fraction of people in the water to the total people at the pool, written like this.

people in water / total people at the pool

Substituting the given numbers:

54 / (54 + 66)

54 / 120

Solve the fraction and multiply by 100 to find the percentage:

54 / 120 = 0.45 x 100 = 45%

0:

y = x² - 3

y = 0² - 3

y = 0 - 3

y = -3

(0, -3)

1:

y = x² - 3

y = 1² - 3

y = 1

y = -2

(1, -2)

2:

y = x² - 3

y = 2² - 3

y = 4 - 3

y = 1

(2, 1)

64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.

Write an equation to determine Sarah's age (a).

Find Sarah's age.

Answers

Answer:64/4+44=a

Sarah is 60 years old

Step-by-step explanation: 64/4 =16.    44+16=60

Multiply this difference by 4, and you get 64 as the result. So:

64 = 4(a - 44)

Now you need to balance the equation. Do the same operation to both sides. To begin, divide both sides by 4.

64/4 = 4(a - 44)/4 becomes

16 = a - 44 To get variables on one side and numerals on the other, add 44 to each side.

16 + 44 = a

60 = a. Sarah is 60 years old.

soccer: mean absolute deviation of 1.2

In which sport were his scores the most spread out?


soccer

basketball

Answers

Answer:

basketball

Step-by-step explanation:

i took the test :)

Basketball have most spread out.

Option B is correct.

What is Standard Deviation?

A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.

We have

Basketball: mean absolute deviation of 4.6

Baseball: mean absolute deviation of 3.5

Soccer: mean absolute deviation of 1.2

As, a high mean absolute deviation tells us that many of the data values are spread out further from the mean.

Here Basketball have highest absolute deviation.

Thus, Basketball have most spread out.

Step-by-step explanation:

The benefits of division of labor include a wealth of natural resources, a stable government with few restrictions, and a sizable workforce that helped it become the world's leading industrial power by the 20th century.

What is Division of Labor?

Division of labor is indeed the division of a work flow into several tasks, each of which is carried out by a different person or group of people. It is one of the fundamental organizational concepts of the production line and is most frequently used in mass production systems.

In any economic organization, the division of work refers to the separation of duties to allow members to specialize. Division of Labor refers to the division of the primary manufacturing process into a number of straightforward sections, each of which is produced by a distinct worker who specializes in producing that particular element.

Thus, the benefits of division of labor include a wealth of natural resources, a stable government with few restrictions, and a sizable workforce that helped it become the world's leading industrial power by the 20th century.

Estimate the difference 7 3/4-2/25 Show your work.

Answers

Answer: 7 3/4 - 2/25 = 767/100  = 7  67/100 = 7.67

Step-by-step explanation:

Conversion a mixed number 7 3/4

to a improper fraction: 7 3/4 = 7 3/4  = 7 · 4 + 3/4= 28 + 3/4 = 31/4

To find a new numerator:

a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4

b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31

c) Write a previous answer (new numerator 31) over the denominator 4.

Seven and three quarters is thirty-one quarters

Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/

100 = 767/100

Answer: 66

Step-by-step explanation: Basically you want to find the area of the whole shape and the white shape, which the whole shape is 96 and the white shape is 30, and subtract 96-30=66

We’re looking for the area of the shaded region (blue rectangle)

First we’ll start by finding the area of the whole shape: 10+2 =12 and 5+3 = 8.

Now that we have that we will multiply 12x8, getting 96.

Now we want to find the area of the white rectangle.
So, 3 x 10 = 30.

Now that we have our two areas, we’ll need to subtract 96-30 = 66. Getting the area of the shaded region.
