Answer:

The following correlation coefficient which is closest to the correlation coefficient of the linear fit of the data shown below, to the nearest hundredth is:

0.77

Step-by-step explanation:

We know that:

  • from the scatter plot the correlation coefficient(r) is zero when there is no relationship between the two variable but here as we know that the relationship is linear hence correlation coefficient can't be zero.

             Hence, r=0 is incorrect.

  • Also as the relation is a positive linear correlation hence r can't be negative.

            Hence r=-0.95 is incorrect.

  • Also, if we draw a line of best fit then all the points will not lie on the line of best fit.

            Hence r=1 is incorrect.

Hence, the correct answer is:

r=0.77

Answer:

$120.14

Step-by-step explanation:

This question is an example of a compound percentage decrease.

To work this out you would first need to convert the percentage of 25 into a decimal. You can do this by dividing the percentage of 25 by 100, this gives you 0.25. This is because percentages are out of 100.

The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.

The final step is to multiply the amount of 900 by 0.75 to the power of 7, this gives you $120.14.

1) Divide 25 by 100.

25/100=0.25

2) Minus 0.25 from 1.

1-025=0.75

3) Multiply 900 by 0.75 to the power of 7.

900*0.75^7=120.14

Which statements are true about the graph of y &lt; Two-thirdsx + 1? Check all that apply. The slope of the line is 1. The line
Marina CMI [18]

The answer would be:

The x-intercept of the boundary line is (-3/2, 0).

The area below the line is shaded.

The slope of the line should be 2/3. The area below the line shaded because the function using y<.....

Coordinate 2,3 doesn't fulfill the function. 

y < 2/3x + 1

3 < 2/3(2)+1

3< 4/3+1

3< 2.3    ---->false

X intercept is when the y variable is zero. If you put it to the equation

 y = 2/3x + 1

0= 2/3x+1

2/3x= -1

x= -3/2

From the given scenario is this particular item, the equation that can be derived for the distance traveled after x seconds is,
                            y = d₀ + (4)x
Substituting the known values x and y in order to solve for d₀ will give us an answer of,
                           13 = d₀ + 4(3)
                                    d₀ = 1 
Thus, the answer is 1 m.
