Answer:
Step-by-step explanation:
For this case we have a linear model given by:
Where X= represent the height.
Y= represent the beats per minute
And the slope is given by 
and the intercept 
We have the mean for x and y given also 
And in order to find the best predicted value we just need to replace the value of X= 65, and we got this:
If we want a confidence interval for the response variable when the predictor variable is x, is given by this formula:
And if we replace we got this:
But for this case since we don't have the deviation we can just express it like this.
<u><em>Answer:</em></u>
Nelson burned the most calories per hour
<u><em>Explanation:</em></u>
To solve this question, we will get the amount calories burned by each in one hour and then compare the two values
To do this, we will divide the total amount of calories burned by the total time
<u>1- For Sabra:</u>
We are given that she burnt 845 calories in 
(which is equivalent to 3.25) hours
<u>Therefore:</u>
Calories burnt in an hour = 
calories/hour
<u>2- For Nelson:</u>
We are given that he burnt 1435 calories in 
(which is equivalent to 4.875) hours
<u>Therefore:</u>
Calories burnt in an hour = 
calories/hour
<u>3- Comparing the two values:</u>
From the above calculations, <u>we can deduce that</u> Nelson burned the most calories per hour
Hope this helps :)
The answer is 45 you put the 4 and the 5 togther
1800 boxes with 24 candies each
Total = 1800 * 24 = 43 200 candies
The machine makes 600 candies in 1 minute
1 candy would take (1/600) minute
43 200 candies would take 43200 * 1/600 = 72
= 72 minutes.
Therefore the 1800 boxes would be done in 72 minutes.
