24 feet
Set up a ratio of object height to shadow length.
So x/32=6/8
8(4)=32 so 6(4) would be 24.

What is 8 more than twice the sum of a number and 3 is the same as -6?

a_sh-v [17]

This can be solver by creating a small equation with x being the number and solving for x. The equation would be 8 + 2( x + 3 ) = -6
Solve for x:
8 + 2( x + 3 ) = -6
Distribute the 2
8+ (2x+6)=-6
Subtract 8
2x+6= -14
Add 6
2x= 8
Divide by 2
x=4

So the number you are looking for is 4

I hope this helps!

Using the formula below or Excel, find the correlation coefficient, r, for this set of scores. Answer choices are rounded to the

RideAnS [48]

The correlation coefficient measures the relationship between the two variables

The correlation coefficient is 0.234

<h3>How to determine the correlation coefficient</h3>

The formula of correlation coefficient is:

$r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})$

Using the dataset from the complete question, we have:

$r = \frac{1}{5 - 1} * 0.9375$

Evaluate the difference

$r = \frac{1}{4} * 0.9375$

Evaluate the quotient

$r = 0.234375$

Approximate

$r = 0.234$

Hence, the correlation coefficient is 0.234
