Here is the histogram of a data distribution. All class widths are 1. What is the median of the distribution?
lidiya [134]
First of all, we have to know what median is.

Median- the middle number.

So we have to organize the numbers in roofer from least to greatest, so we have to count how many 2,3,4,5,6s there are and so fourth.

I’ll have them listed for you.

2 2 2 2 3 4 5 6 7 7 7 8 8 8 8 9 9 9 9 10 10 10 10 10 10.

Next step is to find the middle number (s). If it has an even amount of numbers, we have to take the two middle numbers and divided by two.
If there are an odd amount of numbers, we just pick the middle number.
[i.e: 2 3 4; the middle number here is 3]
[i.e: 2 3 4 5; the middle number is 3+4=7 divided by 2 which equals 3.5]

Okay so let’s count how many numbers there are.
There are 25 numbers in total, so therefore there are 2 middle number (s).

So let’s divided 25/2 to get the two middle numbers, which is 12.5, therefore numbers 12-13 are middle numbers.

So let’s count what number is 12 and 13. When you count the numbers in order, you can tell that 8 and 8 are numbers of 8.

The final step is to just calculate by adding both numbers and dividing by two because we are trying to find the middle number(average number).

8 + 8 = 16
16/2= 8

The median for this question is 8.

Can you give me the brainliest? Or give me a heart? Thank you.

Simplify the expression.
sergiy2304 [10]

Answer:

The simplified expression is:

⇒ 13x-8

Step-by-step explanation:

Given expression:

(9x + \frac{1}{2})+(4x-8\frac{1}{2})

To simplify the given expression.

Solution:

In order to simplify, we will combine the like terms by removing the parenthesis.

We have:

⇒  9x + \frac{1}{2}+4x-8\frac{1}{2}

Combining like terms.

⇒  9x+4x+\frac{1}{2}-8\frac{1}{2}

⇒  13x+\frac{1}{2}-8\frac{1}{2}

In order to combine fractions, we will combine the whole number and the fraction separately.

⇒  13x-8+(\frac{1}{2}-\frac{1}{2})

⇒  13x-8+0

Thus, the simplified expression is:

⇒ 13x-8

Calculate the total surface area of a pipe with inner surface area 1508.5 square cm, outer surface area 2514.2 square cm, and in
algol [13]

Answer:

The total surface area of the pipe is 4123.31 cm²

Step-by-step explanation:

Total surface area (TSA) of a pipe is calculated as;

Outer area of the pipe + Inner area of the pipe + cross section of the two ends

TSA = 2πRL + 2πrL + 2π(R² - r²)

TSA = 2π(RL + rL + R² - r²)

where;

R is the outer radius

r is the inner radius

L is length of the pipe

Determine the length of the pipe

Outer surface area of the pipe is  calculated as;

outer surface of the pipe = 2πRL

2514.2  = 2πRL

2514.2 = (2π x 5) L

2514.2 = 31.42 L

L = 2514.2 / 31.42

L = 80.02 cm

Finally, determine the total surface area of the pipe

TSA = 2π(RL + rL + R² - r²)

TSA = 2π(5x80.02 + 3x80.02 + 5² - 3²)

TSA =  2π(400.1 + 240.06 + 16)

TSA =  2π(656.16)

TSA = 4123.31 cm²

Therefore, the total surface area of the pipe is 4123.31 cm²
