The fraction of the group who had a score of 45 or more is 20/31
<h3>What is a Histogram ?</h3>
It is a method of graphical display of data where the data is displayed using bars of various heights .
From the histogram , we can calculate by either determining the frequency value of group who had a score of 45 or more and divide it by total frequency or
By calculating the number of square in each group who had a score of 45 or more and dividing by the total number of squares.
There are total 31 squares
The health score for a group of people who had a score of 45 or more is 20
Therefore the fraction of the group who had a score of 45 or more is 20/31

1800 is the answer for 1.8x103
Volume ratio is 686/250 = 2.74
Area ratio is
250 yd^3
radii? First solid has vol 250 yd^3 = (4/3)*pi*r^3; find r^3 = --------------
(4/3)*pi
Then r^3 = 187.5 yd^3, and r = 5.724 yd
Second solid has vol 686 yd^3 .... Please find the radius R using precisely the same method.
Then calculate the ratio of the surface areas of the 2 solids:
Solid 1 surface area 4*pi* R^2
----------------------------- = --------------- where R is the radius of the larger
Solid 2 surface area 4*pi*r^2 solid and r is the radius of the smaller
R^2
This ratio comes out to ----------
r^2
Scale factor? Obviously one solid is larger than the other. We have to figure out by how much, by comparing volumes. Actually, we've already done that (see above). We could also determine how much larger R is than r. That, too, would give us the scale factor.
Federal Reserve System. ... a service offered by the Fed to recored receipts and expenditures of bank clients. ... includes the Fed's actions that change the money supply in order to influence the economy.
this is the answer:-)
Answer:
25 dfferent ways
Step-by-step explanation:
The answer is 25 different ways because since there are students and thy line up behind each other you would do 5 times 5 which equals to 25.
