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!

I know I already asked this but I need an explanation on whyyy

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

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 .
