The mean height of married American women in their early twenties is 64.5 inches and the standard deviation is 2.5 inches. The m

Answer:

The equation for regression line and predicting a husband's height for married couples in their early 20s

Equation: Y'=33.67+0.54*X'

Step-by-step explanation:

r=0.5

x'=64.5

Sx=2.5

y'=68.5

Sy=2.7

General regression line equation is:

Y'=a+b*X'

so the slope of the regression line is the linear correlation coefficient multiplied by the standard deviation for y' divided by the standard deviation for x'

$b=r*\frac{S_{y}}{S_{x}}\\b=0.5*\frac{2.7}{2.5}\\b=0.54$

The intercept with axis y is the mean of the decreased by the product of the slope and the mean of x

$a=y'-b*x'\\a=68.5-0.54*64.5\\a=33.67$

The equation regression line then is:

Y'=33.67+0.54*X'

At Shannon's Beading Boutique, 6 out of the 20 beads on clearance are plastic. What percentage of beads on clearance are plastic

yKpoI14uk [10]

Answer:

30%

Step-by-step explanation:

(plastic beads)/(beads on clearance) = 6/20 = 30/100 = 30%

_____

A percentage is a representation of a fraction that has 100 as a denominator. The percent sign (%) is just a shorthand way to write "divided by 100" (/100). The word "percent" means "per hundred", or "divided by 100."

Here, the given fraction (6/20) can be multiplied by 5/5 to make it have a denominator of 100.
