Answer:
If angle a and b are complementary angles, and angle a is 64, complementary equals 90, so 90-64= 26 degrees for angle b.
Answer: σ: 2.76
Step-by-step explanation:
Count, N: 5
Sum, Σx: 125
Mean, μ: 25
Variance, σ2: 7.6
Steps
look at attached pic for formula
σ^2 = 
⇒ 
⇒ 7.6
σ = 
⇒ 2.756809750418
⇒ or 2.76
Answer:
B, E
Step-by-step explanation:
Answer A is wrong: 5 + 2 + x
Answer C is wrong: 5 + x + x
Answer D is wrong: 5 + x*x
F is wrong, because a product is the result of multiplying.
The first way to try to fix this is to apply logarithm to the observations on the dependent variable. This is going to make the dependent variable with high degree of kurtosis normal.
Note that sometimes, the resulting values of the variable will be negative. Do not worry about this, as it is not a problem. It does not affect the regression coefficients, it only affects the regression intercept, which after transformation, will be of no interest.
The answer would be 26 because you're multiplying .5 times 52
