180 degrees is a straight line. It is half of 360 which is a full circle, so if you split the circle in half you'll get a straight line.

The histogram below shows information about the number of books students read in a month:
max2010maxim [7]

Answer:

Option C is true - The number of students who read 4 books or fewer

Step-by-step explanation:

Here, to find the mean and median, we do not have proper information or specific values. We just have the ranges, so both the mean and median cannot be determined.  So, options A and B are not correct.

We can see two bins covering the 9 or more books, so option D cannot be true either.

Therefore, only option C is left and that is true.-  the number of students who read 4 books or fewer.

D=C(1+rt/100) solve for r
xz_007 [3.2K]

Answer:

r= −100c+100d/ct

Step-by-step explanation:

d=c(1+rt/100)

1/100crt+c=d

1/100crt+c+−c=d+−c

1/100crt=−c+d

\frac{1/100crt}{ct/100} = \frac{-c + d}{ct/100}

A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.
snow_tiger [21]

It would be 13.50 because 50% off of 18$ is 9$ but it’s not 50% off itS 25% off so If you take the 50% Off price of 9$ and add 4.50 (One more 1/4th) you get $13.50
