Answer:
1st one is 30,
2nd one is 20,
so the 3rd one will be 30+20 so the answer is 50
Step-by-step explanation:
Get the number without the X and you are deciding by that number for example 5x=10 your going to decide by 5 your 5 cancels on the left and u devise by 5 on the right as well and you get x=2
Answer:
Mean: 9.875
Median: 8
Mode: 7
Minimum: 4
Maximum: 20
Range: 16
Size: 8
Sum: 79
Step-by-step explanation:
How to find the mean?
1. Count the number N of data points in your data set.
2. Sum up all of the data points in your data set (add them all together).
3. Average = Mean = Sum/N.
How to find the median
?
The median is the numeric value separating the upper half of a sample data set from the lower half. The median of a data set can be found by arranging all the values from lowest to highest value and picking the one in the middle. If there is an odd number of data values then the median will be the value in the middle. If there is an even number of data values the median is the mean of the two data values in the middle.
For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5.
For the data set 1, 1, 2, 6, 6, 9 the median is 4. It is the mean of 2 and 6 or, (2+6)/2 = 4.
How to find the mode
Mode is the value or values in the data set that occur most frequently.
For the data set 1, 1, 2, 5, 6, 6, 9 the mode is 1 and also 6.
Hope this helps you! :D
Answer:
Answer 60
Step-by-step explanation:
The distance from an exterior point to the incircle is equal to the tangent length in both cases.
So the 19 is made up of 9 and 10.
The length of the other portion of the tangent from the end of 19 to the tangent point on the right is also 10.
By a similar argument the lower length of the line to the tangent point is 11.
So you have
9 + 9 + 10 + 10 + 11 + 11
18 + 20 + 22 = 60.
Answer:
=4.8875a
Step-by-step explanation:
c(a) = 4.25 a
m(c) = 1.15c
We want to find m(c(a) )= 1.15(4.25a) =4.8875a
