The histogram below shows information about the hours students spent exercising in a week:

A histogram is titled Weekly Exercise, the horizontal axis is labeled Hours of Exercise, and the vertical axis is labeled Students. The range on the horizontal axis is 0 to 4, 5 to 9, and 10 to 14. The values on the vertical axis are from 0 to 10 at intervals of 1. The first bin goes to 4, the second bin to 9, the third bin to 5.

Which information is provided in the histogram?

A:The number of students who exercised 4 hours or more
B: The number of students who exercised 9 hours or fewer
C:The mean hours of exercise
D:The median hours of exercise

Answers

Answer: A

Step-by-step explanation: with my calculation, and the information you have give i have to say it is A.

Answer:

C and D are somewhat correct. We may be able to estimate the mean and median hours from the histogram.

A seems to the closest answer, but not exactly correct.

Step-by-step explanation:

It seems that none of the descriptions is exactly right. The first bin is 0 to 4 hours, so the "4 hours or more is not accurate. The third bin is 10 to 14 hours, so B is wrong.

Answer:

-41.29*  10^-7

Step-by-step explanation:

You would change the order of the numbers by multiplying -4.44 and 9.3 together and multiply 10^-7 and 10^0. Which would now look like this:

(-4.44* 9.3)* (10^-7* 10^0)

-4.44* 9.3= -41.292 and 10^-7* 10^0= 1* 10^-7. So now the equation would look like this:

-41.292* 10^-7

Then round -41.292 to 2 decimal places which would be -41.29.

-41.29*  10^-7

That's the answer. I hope this helps!

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.

Answers

Answer:

U first need to find out the total number of people

22+28

50

and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator

22/50

And now to make it into % we need to ALWAYS multiply the fraction by 100

22/50 x 100

44%

Hope it helps

Answer:

44 %

Step-by-step explanation:

okay so 100% is equal to the whole team or 50 swimmers

100% = 50 swimmers

to find out how much one swimmer is would be to divide the 100% by the total of swimmers.

100% / 50 swimmers

2% = 1 swimmer

so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.

2 x 22 = 44

Question one is last option between 8 and 9

Answer:

question 1: it is between 8 and 9. question 2: option B.

Step-by-step explanation:

1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that the square root of 66 is between 8 and 9.

2. to solve this, we can take the square root of the numbers to begin.

the square root of 25 is 5 (because 5x5=25)

the square root of 16 is 4

20 is actually not squarable, so we can estimate that it is a little greater 4.

the answer would be √16, √20, 4.85, √25

it would be option b.

Quinn's mom went to the same middle school that Quinn is now attending. The current student population is 817 students. Since Quinn's mom attended, the school has experienced a
57% increase in population. About how many students were enrolled at the school when Quinn's mom attended?

Answers

Answer:

520

Step-by-step explanation:

Past number of pupils: p

Increase of 57% = 1.57

Present number of pupils = 817

p x 1.57 = 817

p = 817 divided by 1.57 = 520.382

rounded to the nearest whole number = 520 (this is why the question says "about" how many...)

57 x 817 = 46569

46569 divided by 100 = 465.69

817-465.69 = 351.31

Answer : 351

Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 .
