Which r-value is the best estimate of the correlation coefficient for the variables in the scatter plot?
The best estimate of the r-value of the correlation coefficient for the variables shown in the scatter plot is: C. r = 0.64.
How to Estimate Correlation Coefficient on a Scatter Plot?The farther the points are from each other along the trendline, the closer the r-value is to zero and vice versa.
If the trendline is increasing upwards to your right, the r-value would be positive, and vice versa.
Th scatter plot given shows the trendline is increasing, and the data points are moderately spaced out along the trendline from each other.
Therefore, the best estimate for the r-value is: C. r = 0.64.

Sally can paint a room in 3 hours while it takes Steve 6 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer:
2h
Step-by-step explanation:
You can solve this one by adding their rates, but you have to invert the numbers they give you to find the rate. Rate is measured in something per unit of time, and "per" indicates division. So the rates are: 1/3 of an hour (Sally) and 1/6 of an hour (Steve). So add the rates: 1/3 + 1/6 = 1/2. (1/3 is 2/6, and 2/6 + 1/6 = 3/6). Since their combined rate is 1/2 of a room in one hour, it takes them two hours to paint the room.

9514 1404 393
Answer:
distributive property
Step-by-step explanation:
The distributive property of multiplication over addition tells you ...
a(b +c) = ab +ac
This works both ways, allowing you to eliminate or add parentheses as may be needed.
The common factor of ...
11x +5xy
is x. It may be factored out according to the distributive property to give ...

Evaluate f(x)=e4x+5+2 when x=−2. Give an approximate answer rounded to two decimal places.
Answer:
f(-2) ≈ 2.00
Step-by-step explanation:
f(x) = e^(4x + 2) + 2
At x = -2
f(-2) = e^(4(-2) + 2) + 2
f(-2) = e^(-8 + 2) + 2
f(-2) = e^(-6) + 2
use calculator
f(-2) = 0.002478752176666 + 2
f(-2) = 2.002478752176666
Rounded to 2DP
f(-2) ≈ 2.00
which regression equation best fits these data?
x:-6,-4,-3,-1,1,2,3,4
y:12,15,17,17,15,11,9,6
on graph:(-6,12)(-4,15)(-3,17)(-1,17)(1,15)(2,11)(3,9)(4,6)
a. y=11.73*0.94^x
b. y=0.32x^2+1.26x+15.81
c. y=-0.67x+12.41
d. y=-0.32x^2-1.26x+15.81
Answer:
y = - 0.32x² - 1.26x + 15.81
Step-by-step explanation:
From the graph, it can be deduced that the graph isn't linear nor exponential. The graph shown is a quadratic graph. Hence the regression equation which best fits the model is represented in the form :
y = Ax² + Bx + C
Using technology, the regression model obtained by fitting the data is :
y = - 0.32x² - 1.26x + 15.8
Fitted model is attached below
