What is the median of 7,6,12,19,6,13,16,20,9

2 answers:

4 0

Hello,
First of all, you have to order the number from least to greatest:
7,6,12,19,6,13,16,20,9

6,6,7,9,12,13,16,19,20

We see that there are total 9 numbers. Median means that the middle number, so we separate 4 numbers into two groups
6,6,7,9
13,16,19,20. Now,we see that there is only one number which is 12. As a result, the median is 12. Hope it help!

The mean amount of water in 5 containers is 620 ml the total amount of water in 4 q of the containers is 2750 what is the amount

EleoNora [17]

The correct answer is:

350 ml.

Explanation:

Let x be the amount in the fifth container.

The mean is found by adding all of the amounts together and dividing by the number of containers (in this problem, 5). We know that the total from the other 4 containers is 2750; add this to x, our unknown number. Then we divide by 5 to arrive at our answer of 620.

Algebraically,
 $\frac{2750+x}{5}=620$ 

To solve, multiply both sides by 5:
 $\frac{2750+x}{5}\times 5=620\times 5
\\
\\2750+x=3100$ 

Subtract 2750 from both sides:
2750+x-2750=3100-2750
x=350.

There are 350 ml in the fifth container.

At higher elevations water boils at lower temperatures. The temperature at which water boils is called the boiling point of wate

Leya [2.2K]

B(x) = 100 - 3.5x
84 = 100 - 3.5x
3.5x = 100 - 84 = 16
x = 16/3.5 = 4.6 kilometers

96 = 100 - 3.5x
3.5x = 100 - 96 = 4
x = 4/3.5 = 1.1 kilometers

Therefore, the boiling point of water is between 84°C and 96°C at elevations of between 4.6 kilometers and 1.1 kilometers.

What is the area to this shape ?

Dafna1 [17]

Answer:

249.42 units²

Step-by-step explanation:

Given only the apothem of an n-sided regular polygon, the area can be computed as ...

... A = n·a²·tan(180°/n)

For n=3 and a=4√3, this is ...

... A = 3·(4√3)²·tan(60°)

... A = 3·48·√3 = 144√3 . . . . units²

... A ≈ 249.42 units²
