Answer:

Hello Love! The median is simply just the number in the middle so sense we have 2 numbers in the middle our median will be 3 and 6

The mean is when you add up the numebers then divide by how many numbers there are so...

3 + 2 + 4 + 6 + 3 + 6 + 1 + 2 + 5 + 4 = 36 so 36 divided by 10 is 3.6

The range is simply just the biggest number in the sequence subtracted by the smallest number so... 6 - 1 = 5 so 5 would be our range!

Hope this helps you.

Katen [24]

Answer:

10.14 feet per year.

Step-by-step explanation:

Given:

Over the next 3 1/2 years, a tree grew to a final height of 35 1/2 feet.

Question asked:

During those 3 1/2 years, what was the average yearly growth rate of the height of the tree?

Solution:

We can find the average yearly growth rate by using average formula, taking

final height of the tree as sum of observation and time span taken to growth as number of observation:-

As we know:

$Average=\frac{Sum\ of\ observation}{number \ of\ observation}$

$=35\frac{1}{2} \div3\frac{1}{2} \\ \\ =\frac{71}{2} \div\frac{7}{2} \\ \\ =\frac{71}{2}\times\frac{2}{7} \\ \\ =\frac{142}{14} =10.14\ feet$

Thus, during $3\frac{1}{2} \ years$ , the average yearly growth rate of the height of the tree was 10.14 feet per year

What is the solution set of 2/5 (x+4) -3/5 (2x+3) = 2/5(2-x)-1

PtichkaEL [24]

Step-by-step explanation:

2/5(x+4) - 3/5(2x+3) = 2/5(2-x)-1

2/5(x+4)-3/5(2x+3) = 2/5x-1/1(2-x)

2/5(x+4)-3/5(2x+3) = -2/5(2-x)

2/5x+8/5 - 6x/5 + 9/5 = -4/5 - (-2x/5) (-x- = +)

2x/5 + 8/5 - 6x/5 + 9/5 = -4/5 + 2x/5

(take like terms)

2x/5 - 6x/5 - 2x/5 = -4/5 - 9/5 - 8/5

( Find their L.C.M ) (5 is the LCM)

2x - 6x -2x / 5 = -4 - 9 - 8 / 5

-10x / 5 = -13 / 5

( cross multiply)

-50x = -65

x = -65/50

x = -1.3 ( decimal)

or x = 13/10 (improper fraction)

or x = 1 ³/10 ( mixed fraction).

Hope this helps.

Good luck.
