d=16

d-10-(-2+1/2*d)=0

simplify

(d-10)-(-2+(1/2*d))=0

rewrite as an equivalent fraction

(using 2 as the denominator)

-2=-2/1=-2*2/2

adding fractions with common denominator

-2*2+d/2=d=4/2

(d-10)-(d-4)/2=0

rewrite the whole as a fraction using 2 as your denominator

d-10= d-10/1= (d-10)*2/2

d-16/2=0

get rid of the denominator

d=16/2*2=0*2

solve

d-16=0

d=16

The measure of one of two complementary angles is 6 degrees less than one half the measure of the other. Find the measure of the

solmaris [256]

It's helpful to choose letters to represent the measures of these complementary angles. Let x represent one and y the other.

What does "complementary angle" mean? x + y = ??

Let x be the smaller angle. First, we take "half the measure of the larger angle," or (y/2). Then we subtract 6 degrees from this result (y/2). The result is the xmaller angle, x.

Now you have two equations in x and y. Solve for one of these angles, and then find the other. Please show your work.

If the correlation between height and weight of a large group of people is 0.74, find the coefficient of determination (as a per

Vika [28.1K]

Answer:

B. The coefficient of determination is 54.76%. Therefore, 54.76% of the variation in weight can be explained by the regression line.

Step-by-step explanation:

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.

The coefficient of determination is a measure to quantify how a model explains an dependent variable.

The formula for the correlation coeffcient is given by:

$r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}$

The formula for the coefficient of determination is $r^2$

In our case the correlation coefficient obtained was 0.74

And the determination coefficient is $R=0.74^2 =0.5476$ , and if we convert this into % we got 54.76%

Assume that height is the predictor (X) and weight is the response (Y)

And the best answer for this case is:

B. The coefficient of determination is 54.76%. Therefore, 54.76% of the variation in weight can be explained by the regression line.
