Answer:
x=12
Step-by-step explanation:
Simplifying
30 + 4x + 2 = 8 + 6x
Reorder the terms:
30 + 2 + 4x = 8 + 6x
Combine like terms: 30 + 2 = 32
32 + 4x = 8 + 6x
Solving
32 + 4x = 8 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
32 + 4x + -6x = 8 + 6x + -6x
Combine like terms: 4x + -6x = -2x
32 + -2x = 8 + 6x + -6x
Combine like terms: 6x + -6x = 0
32 + -2x = 8 + 0
32 + -2x = 8
Add '-32' to each side of the equation.
32 + -32 + -2x = 8 + -32
Combine like terms: 32 + -32 = 0
0 + -2x = 8 + -32
-2x = 8 + -32
Combine like terms: 8 + -32 = -24
-2x = -24
Divide each side by '-2'.
x = 12
Simplifying
x = 12
Answer:
![P(A\ n\ B) = 0.557](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29%20%3D%200.557)
Step-by-step explanation:
Given
![P(A) = 0.78](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.78)
![P(B) = 0.65](https://tex.z-dn.net/?f=P%28B%29%20%3D%200.65)
![P(A\ u\ B) = 0.873](https://tex.z-dn.net/?f=P%28A%5C%20u%5C%20B%29%20%3D%200.873)
Required
Determine ![P(A\ n\ B)](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29)
From laws of probability, we have:
![P(A\ n\ B) = P(A) + P(B) - P(A\ u\ B)](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29%20%3D%20P%28A%29%20%2B%20P%28B%29%20-%20P%28A%5C%20u%5C%20B%29)
Substitute in values
![P(A\ n\ B) = 0.78 + 0.65 - 0.873](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29%20%3D%200.78%20%2B%200.65%20-%200.873)
![P(A\ n\ B) = 0.557](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29%20%3D%200.557)
Hence,
<em> is calculated to be 0.557</em>
Answer:
Set 2
Step-by-step explanation:
First find the median of each set (the median being the number in the middle):
(1) { 4,7,10,13,16} = 10
(2) {8,9,10,18,19} = 10
(3) {8,9,10,11,12} = 10
(4) {1,2,10,11, 12} = 10
Then find the mean of each set (the mean being average of all the numbers, to find the average add up all the numbers and divide by the amount of numbers):
(1) { 4,7,10,13,16} = 10
(2) {8,9,10,18,19} = 12.8
(3) {8,9,10,11,12} = 10
(4) {1,2,10,11, 12} = 7.2
the answer being 12.8 since 12.8 is greater than 10
