Answer:
x = 7
Step-by-step explanation:
A, B, and C are collinear B is between A and C.
AC = AB + BC
2x + 1 = x + 4 + 2x - 10
2x + 1 = 3x - 6
2x - 3x = - 6 - 1
- x = - 7
x = 7
Answer: x = 8, y = 2, coordinates (8,2)
Step-by-step explanation:
2x = 4y + 8 (divide by 2 to get value of x)
x = 2y + 4
(now substitute x into the second equation to find value of y)
2y + 4 - 2y = 4
2y - 2y = 4 - 4 (divide by 2 to get value of y)
y - y = 2 - 2
y = 2
Now plug in value of "y" to get value of "x".
x - 2(2) = 4
x - 4 = 4
x = 8
Coordinates (8,2)
Answer:
11
Step-by-step explanation:
Just make your dot plot so that the amount of dots corresponding to the number is the amount of times the number shows in the box. :)
The coding of the statistic is used to make it easier to work with the large sunshine data set
- The mean of the sunshine is 3.05

- The standard deviation is approximately <u>18.184</u>
<u />
Reason:
The given parameters are;
The sample size, n = 3.
∑x = 947
Sample corrected sum of squares, Sₓₓ = 33,065.37
The mean and standard deviation = Required
Solution:

The mean of the daily total sunshine is therefore;



- The mean ≈ 3.05

Alternatively
,
The mean of the daily total sunshine,
≈3.05

Therefore;

Therefore;
The standard deviation,
≈ <u>18.184</u>

Answer:
780
Step-by-step explanation:
Explanation:
To get from
5% to 100% you multiply by 20, so multiply the number in this case 39 by 20 percent.
