If Jim =5x - 8 and LM =2x -6,which expression represents JL?
Answers
Answer:
The correct answer is A) 3x - 2
Step-by-step explanation:
In order to find this, take the value of JM and subtract the value of LM. This will give you JL.
JM - LM = JL
5x - 8 - (2x - 6) = JL
5x - 8 - 2x + 6 = JL
3x - 2 = JL

If the value of the mean is 55.78. Then the standard deviation will be 10.98.
What is a standard deviation?
It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.
The data set is given below.
58, 77, 31, 54, 58, 54, 56, 58, 56.
Then the mean of the data set will be
Mean = (58 + 77 + 31 + 54 + 58 + 54 + 56 + 58 + 56) / 9
Mean = 502 / 9
Mean = 55.78
Then the standard deviation will be
On further solving we have
SD = 10.98
If the value of the mean is 55.78. Then the standard deviation will be 10.98.

The correct option is C. 9 houses could 18 men paint in 6 hours.
Step by step explanation:
Let the number of houses paint by 18 men in 6 hours be x.
One man can paint one house in 12 hours.
The part of house painted by a man in 1 hour is .
The part of house painted by a man in 6 hour is
The total number of men is 18. Therefore the number of houses painted by 18 men is
Therefore correct option is C. 9 houses could 18 men paint in 6 hours.

To find the solution set of the equation 8x₁ + 2x₂ - 5x₃ + 6x₄ = 1, we need more information. The equation has four variables (x₁, x₂, x₃, and x₄), but only one equation. In order to find a unique solution, we need as many equations as there are variables. Without additional equations, we cannot determine a specific solution set for the given equation.
Please provide more equations or constraints to help narrow down the solution set.
