10m + n^2/4
m = 5
n = 4
We can now substitute numbers in for the variables.
10(5) + (4)^2/4
50 + 4^2/4
50 + (4 * 4)/4
50 + 16/4
50 + 4
= 54
Answer:
x=53/4 or 4x=53
Step-by-step explanation:
First move the variable to the left-hand side and change its sign.
6x+12-10x=-41 to 6x-10x=-41-12
Then collect the like terms
6x-10x=-41-12 to -4x=-41-12 which equals to -4x=-53
Now you divide both sides of the equation by -4
-4x=-53 to x=53 over 4 then if you want you divide which gives you x=13.25
Second way:
Kind of the same thing as the first one
Move the variable to the left-hand side and change its sign
6x+12=10x-41 to 6x=12-10x=-41
Then you collect the like terms
6x-10x=-41-12 to -4x=-41-12
Now you multiply both sides of the equation by -1
-4x=-53 to 4x=53
Answer:
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given mean of the Population 'μ' = 374
Variance of the Population σ² = 1090
Standard deviation of the Population 'σ ' = √1090 = 33.01
Given 'X' be a random variable in normal distribution
Z = - 1.64
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = P( Z < - 1.64 )
= 1- p(Z > 1.64)
= 1 - ( 0.5 + A(1.64)
= 0.5 - 0.4495
= 0.0505
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
Answer:
(4 + x) * 2
Step-by-step explanation:
twice the sum means the total will be multiplied by 2 and sum is addition. So 4 and a number (x).
