Put all of the numbers you have (starting from the smallest number to the biggest) in a line. Then the number in the middle is the median.

Answer:

It's quite simple, let me explain..

Step-by-step explanation:

The median is the middle of a data set, so you would need to find the exact middle of your data set.

If your data set is odd, and has an odd amount of numbers, just get the number exactly in the middle, and that would be your median. But when your data set has an even amount of numbers, it is a bit tricky.

Here's an example:

85, 78, 96, 83, 77

As you can see, this set has an odd amount of numbers, 5 numbers to be exact. The median would be 96 because it is exactly in the middle.

An example of a data set with even numbers would be this:

1, 2, 3, 4

What you would do is add the two numbers in the middle, and divide by two.

In this case, 2 and three are in the middle, so you would add 2 and 3, which is 5. Then you would divide 5 by two which is 2.5

2.5 Would be your median.

Hopefully this made sense, please ask questions if you have any.

IRINA_888 [86]

Answer:

14

Step-by-step explanation:

Given the following equation;

4³ - (2 + 2³) * 5

4*4*4 - (2 + 2*2*2) * 5

64 - (2 + 8) * 5

64 - (10) * 5

64 - 50 = 14

Note: the rule of BODMAS was applied.

The diameter of a cone is 34 ft. the height is 16 ft what is the volume in cubic ft?
Ilia_Sergeevich [38]

Answer:

4842.24 cubic feet

Step-by-step explanation:

Use the formula for the volume of a cone, V = \pir²\frac{h}{3}

The diameter of the cone is 34 ft, so the radius is 17 ft.

Plug in the radius and height into the formula, and solve for the volume:

V = \pir²\frac{h}{3}

V = \pi(17)²\frac{16}{3}

V = \pi(289)\frac{16}{3}

V = 4842.24

So, the volume of the cone is 4842.24 cubic feet

geniusboy [140]

Answer:

1) 10^9

2) 10^0

3) 10^3

Step-by-step explanation:

1) You divide 10^12 and 10^7 = 10^5

10^4 × 10^5 = 10^9

2) You divide 10^3 and 10^3 = 10^0

10^0 × 10^4 = 10^0

3) You multiply 10^4 × 10^3 × 10^6 = 10^13. Then you divide 10^13 and 10^10 = 10^3

Lorico [155]

Answer:

E

Step-by-step explanation:

Confidence Interval = mean + or - error margin

Mean = 42,000, error margin = width of estimate of the parameter ÷ 2 = 175 ÷ 2 = 87.50

We can be 95% confident that the population mean is 42,000 plus or minus 87.50
