C

By the law of sines, $\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}$ where A, B, C are the angles and a, b, c are the lengths of the sides opposite their respective angles. In this case, $110^{\circ}$ is opposite 4.6 and A is opposite 3.2, so $\frac{sinA}{3.2}=\frac{sin(110^{\circ})}{4.6}$ , giving the answer.

Which of the choices below is not a possible correlation coefficient?

fiasKO [112]

Answer:

The condition for r is the following:

$-1 \leq r \leq 1$

And for this case if we analyze the options the only impossible value is given by:

1.0528

Because this value is higher than 1 and not satisfy the general limits for r

Step-by-step explanation:

The correlation coefficient is a measure of dispersion and is a value between -1 and 1, and is defined as:

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

The condition for r is the following:

$-1 \leq r \leq 1$

And for this case if we analyze the options the only impossible value is given by:

1.0528

Because this value is higher than 1 and not satisfy the general limits for r

A rectangular table is fivetimes as long as it is wide. if the area is 80ftsquared,find the length and the width of the table.

SOVA2 [1]

A = L * W
A = 80
L = 5W

80 = W(5W)
80 = 5W^2
80/5 = W^2
16 = W^2
sqrt 16 = W
4 = W <=== width is 4 ft

L = 5W
L = 5(4)
L = 20 <=== length is 20 ft
