Step-by-step explanation:
84/56 =69/x
84x = 69 x 56
x = (69 x 56)/84
x = 46
A 25% discount.
Discount = 25/100 Price
New Price = 75/100 price
Old Price = New Price + Discount.
Logb1=0 log b 1 = 0 . This follows from the fact that b0=1 b 0 = 1 .
logbb=1 log b b = 1 . This follows from the fact that b1=b b 1 = b .
logbbx=x log b b x = x . This can be generalized out to logbbf(x)=f(x) log b b f ( x ) = f ( x ) .
Answer:
The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.
