Which r-value is the best estimate of the correlation coefficient for the variables in the scatter plot?
Answers
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?
Answers
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.

b. y=0.32x^2+1.26x+15.81
c. y=-0.67x+12.41
d. y=-0.32x^2-1.26x+15.81
Answers
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

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

Step-by-step explanation:
Here is 90 divided by 1/3 displayed mathematically in colors:
90 ÷ 1/3
The numbers in 90 divided by 1/3 are labeled below:
90 = whole number
1 = numerator
3 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
90x3/1 = 270/1
Answer: 270/1
Step-by-step explanation:
90/1*1/3 you have to do the reciprocal so it turns to 90/1*3/1= 270/1

Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Sample 1 :
Mean = (79.2 + 78.8 + 80 + 78.4 + 81) / 5 = 79.48
Range = 81 - 78.4 = 2.6
Sample 2 :
Mean = (80.5 + 78.7 + 81 + 80.4 + 80.1) / 5 = 80.14
Range = 81 - 78.7 = 2.3
Sample 3 :
Mean = (79.6 + 79.6 + 80.4 + 80.3 + 80.8) / 5 = 80.14
Range = 80.8 - 79.6 = 1.2
Sample 4 :
Mean =(78.9 + 79.4 + 79.7 + 79.4 + 80.6)/5 = 79.6
Range = 80.6 - 78.9 = 1.7
Sample 5 :
Mean = (80.5 + 79.6 + 80.4 + 80.8 + 78.8)/5 = 80.02
Range = 80.8 - 78.8 = 2
Sample 6 :
Mean =(79.7 + 80.6 + 80.5 + 80 + 81.1)/5 = 80.38
Range = 81.1 - 79.7 = 1.4
Xbar = mean of the means
Xbar = (79.48+80.14+80.14+79.6+80.02+80.38) / 6 = 79.96
Rbar = Mean of the sample ranges
Rbar = (2.6 + 2.3 + 1.2 + 1.7 + 2 + 1.4) / 6 = 1.87
n =5 ;D4 = 2.11 ; D3 = 0
From table, D4 = 2.11 ; D3 = 0
Range chart :
Upper Control limit, UCL = D4 * Rbar ; 2.11*1.87 = 3.9457 = 3.95
Lower Control limit, LCL = D3 * Rbar ; 0*1.87 = 0
Mean chart :
Xbar ± A2 * Rbar
From the table :
n = 5 ; A2 = 0.58
Lower control limit(LCL) = Xbar - A2*Rbar
LCL = 79.96 - (0.58*1.87) = 78.8754 = 78.88
Upper Control Limit (UCL) = Xbar + A2*Rbar
UCL = 79.96 + (0.58*1.87) = 81.0446 = 81.04
(78.88 ; 81.04)
The value of Each sample mean falls within the mean interval, Hence, We can conclude that process is on control.
