Answer: D. There is a strong negative association between the variables.

Step-by-step explanation:

We know that when the value of the correlation coefficient lies between -1 to -.05 , then we say there is strong negative correlation between the variables.

When the value of the correlation coefficient lies between 0.5 to 1, then we say there is strong positive correlation between the variables.

Given : In one study, it was found that the correlation coefficient between two variables is -0.93.

∵ -1< -0.93 <-0.5

Then , it indicates that there is a strong negative association between the variables.

A child bounces a 48 g superball on the sidewalk. The velocity change of the super bowl is from 23 m/s downward to 14 m/s upward

mestny [16]

Answer:

$F_{a}$ = 0.0009866 N

Step-by-step explanation:

For resolving this problem we can use the impulse-momentum theorem; this theorem establishes that the change in momentum of an object equals the impulse applied to it

The impulse is defined how:

I = $F_{a}$ Δt

$F_{a}$ : Average force

Δt = Time interval

Then:

$mv_{f}-mv{o} = F{a}$ Δt

(0.048)(14) - (0.048)(-23) = $F_{a}$ (1800)

0.672 + 1.104 = $F_{a}$ 1800

1.776 = $F_{a}$ 1800

$F_{a}$ = $\frac{1.776}{1800}$

$F_{a}$ = 0.0009866 N

line cd passes through points c(3, –5) and d(6, 0). what is the equation of line cd in standard form? 5x 3y

SOVA2 [1]

The equation of the line CD that passes through points C(3 , -5) and D(6 , 0) is 5x - 3y - 30 = 0.

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The two-point form of the equation of a line can be used to form the equation of a line if two points are given.

$(y-y_{1} )=\frac{y_{2} -y_{1} }{x_{2} -x_{1}} (x-x_{1} )$

Substituting the values,

$(y--5 )=\frac{0 --5 }{6 -3} (x-3)$

$(y+5 )=\frac{5 }{3} (x-3)$

$(y+5 )=\frac{5 x}{3} -5$

$3(y+5 )=5x -15$

$3y+15=5x -15$

$3y=5x-30$

Meanwhile, the standard form of equation of a line is ax + by + c = 0, where a and b are the coefficients, x and y are the variables, and c is the constant term.

5x - 3y - 30 = 0
