<span>Easiest way is to flip the divisor and multply.

4/9 divided by 1/3
is the same as 4/9 times 3/1

Should be pretty easy to go the rest of the way yourself.</span>

A/b divided by c/d=a/b time d/c
the reason it works is

you have
\frac{ \frac{4}{9} }{ \frac{1}{3} }
fractions in the denomenator is scary
make it one
remember that a/b times b/a=1 so 1/3 times 3/1=1
times the whole thing by 1 to keep is same
\frac{ \frac{4}{9} }{ \frac{1}{3} } times \frac{ \frac{3}{1} }{ \frac{3}{1} }=
\frac{ (\frac{4}{9})(\frac{3}{1}) }{ (\frac{1}{3})(\frac{3}{1}) }=
\frac{ \frac{12}{9} }{ \frac{3}{3} }=
\frac{ \frac{12}{9} }{ 1}=
12/9=4/3

reault is 4/3

Bill is in a class of 15 boys and 35 girls 40 percent of the students in the class take the bus to school how many students do n
GREYUIT [131]

the gender of the kids does not matter so it can be discarded.

you add up how many boys and girls in the class to make a total of 50 kids

your 100% is 50

meaning 40% of 50 is 20

so if 20 kids took the bus to school then 30 did not take the bus.

How do you find endpoints of a line segment with a given endpoint and midpoint?
seraphim [82]

In order to find the second endpoint or a line segment given the first and the midpoint, you need to realize that the midpoint is an average of the two endpoints. Given that fact, we can derive this formula looking at x values of points A and B with midpoint M. Remember this is only looking at the x values.

(A + B)/2 = M

So if we are looking for A, we can solve for A and use this modified formula.

(A + B)/2 = M

A + B = 2M

A = 2M - B

Now we can do this with the y values of these points as well. We then have the coordinates of both parts of A.

9,13,43,55 what is the mean absolute deviate (MAD) of their ages
lisov135 [29]

Answer:

The mean absolute deviation of this data \{9,13,43,55\} is MAD =19.

Step-by-step explanation:

The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

The steps to find the MAD include:

  1. find the mean (average)
  2. find the difference between each data value and the mean
  3. take the absolute value of each difference
  4. find the mean (average) of these differences

To find the mean absolute deviation of this data \{9,13,43,55\} you must

Step 1: Calculate the mean.

\:mean=\bar{x}= \frac{9+13+43+55}{4} =\frac{120}{4}=30

Step 2: Calculate the distance between each data point and the mean and take the absolute value of each difference .

|9-30|=21\\|13-30|=17\\|43-30|=13\\|55-30|=25

Step 3: Add the distances together.

21+17+13+25=76

Step 4: Divide the sum by the number of data points.

MAD = \frac{76}{4} =19
