Take 3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together

=83

Now you divide 83 by the number of terms in the sample set, which is 20.  

83/20 = 4.15

For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.  

final answer= 4.2

A tree grow 1/4 foot in 1/12 year.
lilavasa [31]

Answer:

Part A) The rate is \frac{12}{4}\ \frac{feet}{years}

Part B) In 1 year the tree grows 3 feet

Step-by-step explanation:

Part A)  write the rate at which this tree grows as a fractions

we know that

To find out the rate at which the tree grows divide 1/4 foot by 1/12 year

so

\frac{(1/4)}{(1/12)}=\frac{12}{4}\ \frac{feet}{years}

Part B) how many feet does the tree grow in 1 year?

we know that

The tree grows at rate of \frac{12}{4}\ \frac{feet}{years}

Simplify

\frac{3}{1}\ \frac{feet}{year}

That means ----> The tree grows 3 ft in 1 year

therefore

In 1 year the tree grows 3 feet
