36 walls can be painted in 8 hours. 4 1/2 times 8 = 36
A correlation coefficient of 0.9 is more likely. A correlation coefficient of 1.0 denotes that the probability of an event happening is certain (i.e. 100% likely to occur). When analysing statistical data, it is unlikely that you will come across events with absolute certain probabilities. For example, meteorologists can predict the weather to an extent where they are confident that the prediction will be correct, but they cannot be certain as the weather can be unpredictable at any time.
Answer:
When someone puts on 20 pounds then, the rate of change of height or the height increases by 0.534 inches.
Step-by-step explanation:
We are given the following equation:
Predicted height = (0.0267 inches per pound)(weight) + 65.2
Let y b the predicted height in inches and x be the weight in pounds.
![y =65.2 + 0.0267x](https://tex.z-dn.net/?f=y%20%3D65.2%20%2B%200.0267x)
Comparing to general form of equation:
![y = mx +c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2Bc)
where m is the slope and c is the y-intercept.
m = 0.0267
Interpretation of slope:
Th slope tells us about the rate of change that is when the weight increases by 1 unit that is 1 pound then, the height increases by 0.0267 inches.
When someone puts on 20 pounds:
![y(x+20)-y(x) =65.2 + 0.0267(x+20) - 65.2 - 0.0267x\\y(x+20)-y(x) = 0.534](https://tex.z-dn.net/?f=y%28x%2B20%29-y%28x%29%20%3D65.2%20%2B%200.0267%28x%2B20%29%20-%2065.2%20-%200.0267x%5C%5Cy%28x%2B20%29-y%28x%29%20%3D%200.534)
Interpretation:
Thus, when someone puts on 20 pounds then, the rate of change of height or the height increases by 0.534 inches.
