Mathematics

Start by ordering your data, the pages in each chapter, from smallest to largest - that way you can read it better:
9, 13, 15, 15, 17, 17, 18, 19, 20, 22, 24, 25

A histogram represents the data using a range of values on the x axis (number of pages). For your histogram, the ranges are 0-9, 10-19, and 20-29. On the y axis (number of chapters), you fill in the bar up to how many chapters fall into each of the ranges. You're given data that tells you how many pages are in each chapter, with each data value being a chapter, so just count up how many data values fall into each of the ranges:

For 0-9 pages: 1 chapter (9)
For 10-19 pages: 7 chapters (13, 15, 15, 17, 17, 18, 19)
For 20-29 pages: 4 chapters (20, 22, 24, 25)

Now look at the histograms you're given. Find the one that has the bar filled up to 1 chapter for 0-9 pages, 7 chapters for 10-19 pages, and 4 chapters for 20-29 pages. 

Your answer is B.

ammar hikes 23/4 miles of nature trail in 1 hour and 15 min .How many miles of trail does ammar hike per hour? pleas help me to
telo118 [61]
23/4 miles is as much as 5 3/4 miles. We can also write it as a decimal, because 5 3/4 = 5,75 miles.

If Ammar hikes 5,75 miles in 1 1/4 hour, then we need to find out what distance does he hike in 1/4 hour (15 minutes). To do that we can just divide 5,75 by 5 (because dividing 1 1/4 by 5 will give us 1/4 we're looking for).

5,75 / 5 = 1,15

It means that in one hour Ammar hikes 5,75 - 1,15 = 4,6 miles.

We can also write it as a fraction:

4,6 = 4 6/10 = 4 3/5 = 23/5 miles

Just pick whichever form you like :)

The probability of three independent events happening one after the other is the multiplication of the probability of the single events.

The probability of spinning an odd number is 5/10=1/2, because there are 5 odd numbers (1,3,5,7 and 9) out of the 10 numbers from 1 to 10.

The probability of spinning a number less than 4 is 3/10, because there are 3 numbers (1,2 and 3) that are less than 4 out of the 10 numbers from 1 to 10.

The probability of spinning a 7 is 1/10, because you only have one good outcome out of 10.

So, the probability of winning the game is

\dfrac{1}{2}\times\dfrac{3}{10}\times\dfrac{1}{10} = \dfrac{3}{200}

Can someone help me ?

You first need to multiply the whole second equation by to. So, your two equations would then be -8x + 5y = -9 and 8x + 6y = -46. You then add the two equations to get 11y = -55. This would mean you get y = -5. Then you substitute -5 for y in the first equation. This would mean it would be -8x -25 = -9. Then you add 25 to both sides to get -8x = 16. Then you divide both sides by -8 to get x = -2.
