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
58, 77, 31, 54, 58, 54, 56, 58, 56
If the value of the mean is 55.78. Then the standard deviation will be 10.98.
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.

Answer:
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.
B. The 8th value
C. The 7th value
D. The mean of the 7th and 8th values
65% of the floor space is covered, how many square feet are NOT covered?
Answer:
47,250 ft^2
Step-by-step explanation:
Area: 450 * 300 = 135,000 ft^2
65% of 135,000 =
135,000 * 0.65 = 87,750 ft^2 (space covered)
135,000 - 87,750 = 47,250
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.
Answer:
£9000
Step-by-step explanation:
= £10 000×5×2
100
= 1000
= £10 000-1000
= £9000
