We have five value in the data-set
The third value will be 10 since we want the median to be 10
We want the mean to be 14
To find the mean of a data set, we divide the sum of the values by the number of values
Mean = Sum of values ÷ Number of values
14 = Sum of values ÷ 5
Sum of values = 14 × 5
Sum of values = 70
So we need 5 values that add up to 70, one of the value is 10, which is the median. We would want two values that are smaller than 10 and two values more than 10.
These four value must add up to 70 - 10 = 60
From here we can do trial and error:
Choose any two values less than 10, say 9 and 8
We now have in total 8 + 9 + 10 = 27
We have 70 - 27 = 43 left to find
Choose any two values that are bigger than 10 that add up to 43, for example, 20 and 23
Now we have our 5 values;
8 9 10 20 23
Do the checking bit:
We can see from the set, the median is 10
Mean = [8+9+10+20+23] ÷ 5 = 70 ÷ 5 = 14
We can have values other than 8, 9, 20 and 23 as long as two values smaller than 10 and two values more than 10. All five values must add up to 70.
Answer:
7.9982
Step-by-step explanation:
-The function for an earthquake's magnitude is given by R = 0.67log(0.37E) + 1.46
-E is energy in kwh.
#For 15,500,000,000 kilowatt hours the magnitude would be:
Hence, the earthquakes magnitude is 7.9982
Answer:5x^(2)-21x+4
Step-by-step explanation:
The 6 people be assigned in 720 different ways to chair the subcommittees.
<u>Step-by-step explanation:</u>
Given that,
- There are 6 people to be assigned to the chair committees.
- So, you need to find that in how many ways they can be assigned their seats.
This can be calculated by Permutation.
The number of arrangements in which the order of the objects matters is calculated as permutation.
The permutation is given as ⇒ P = n!
Here we can 6 people to be assigned. Therefore n = 6.
⇒ Number of ways can be arranged = 6!
⇒ 6×5×4×3×2×1
⇒ 720
∴ The 6 people be assigned in 720 different ways to chair the subcommittees.
By the rules of secants, 50° is half the sum of 20° and x.
50° = (20° + x)/2
100° = 20° + x
80° = x
