Your answer is 27.31 because u multiply 25.95 by 5.25 then divide it by 100 then add 25.95 to it
Answer:
2 7/12.
Step-by-step explanation:
Subtracting:
3 3/4 - 1 1/6
Bring together the whole numbers and the fractions:
= 3 - 1 + 3/4 - 1/6 The LCD of 4 and 6 is 12 so we have:
3 - 1 + 9/12 - 2/12
= 2 + 7/12
= 2 7/12.
Answer:
2 hours = 1,100
6 hours = 3,300
Step-by-step explanation:
divide 1,650 by 3 hours and get 550 as the average miles traveled per hour
times 550 by the hours desired and get you answer
hope this helps!!
Step-by-step explanation:
domain is the x value
range is the y values
function is when the 2 points are not on the same like for graphs and x does not repeat on table
Answer:
Check Explanation
Step-by-step explanation:
According to the Central limit theorem, the population mean (μ) is approximately equal to the mean of sampling distribution (μₓ).
And the standard deviation of the sampling distribution (σₓ) is related to the population standard deviation (σ) through
Standard deviation of the sampling distribution = (Population standard deviation)/(√N)
where N = Sample size
σₓ = (σ/√N)
So, population mean (μ) = Mean of sampling distribution (μₓ)
Population Standard deviation = (Standard deviation of the sampling distribution) × √N
= σ × √N
A) The expected value of a given distribution is simply equal to the mean of that distribution.
Hence, the expected value of random variable Y thay varies with different samples is given as
E(Y) = Mean of sampling distribution = μₓ
But μₓ = μ
Hence, E(Y) = μ (Proved)
B) Var (Y) is given as the square of the random distribution's standard deviation.
Var (Y) = (standard deviation of the sampling distribution)²
= (σ/√N)²
= (σ²/N) (Proved)
Hope this Helps!!!
