Answer:

Option c - 20          

Step-by-step explanation:

Given : The set of data

18, 15, 22, 18, 25, 19, 23

To find: The mean of the data?

Solution :

Mean is defined as the sum of the number of observation by total number of observation.

M=\frac{\sum x_n}{n}

M=\frac{18+15+22+18+25+19+23}{7}

M=\frac{140}{7}

M=20

Therefore, The mean of the data is 20.

So, Option c is correct.

Look at the data set below:
Elenna [48]
Median: Sort from least to greatest and find the # in the middle.
Sort: 54, 58, 58, 60, 62. 
Number in the middle: 58, so the median is 58.
Mode: 58, because it appears most. 
Range: Subtracting bigger number from smaller number.
Finding it: 62-54 = 8
If you want to find the mean, then here:
Mean: Solving average (adding all #s together and dividing by how many numbers are there) <span>58 + 54 + 62 + 58 + 60 = 292.
</span>Divide by 5 = 58.4
Hope that helps you. Good luck with it.

Write the ordered pair that represents MP. Then find the magnitude of MP.
jarptica [38.1K]

Answer:

(23,-4):\sqrt{545} units

Step-by-step explanation:

We are given that M(-19,4)and P(4,0)

We have to find the ordered pair that represents MP and find the magnitude of MP.

MP=P-M

MP=(4,0)-(-19,4)=(4+19,0-4)

MP=(23,-4)

Magnitude of MP=\sqrt{(23)^2+(-4)^2}

Magnitude of MP=\sqrt{529+16}

Magnitude of MP=\sqrt{545} units

Hence, .option c is true.

Answer:c.(23,-4):\sqrt{545} units
