Answer:
The number of pages had Clint read prior to study hall were <u>127 pages</u>.
Step-by-step explanation:
Given:
Clint after 20 minutes is on page 151.
And, after 45 minutes he is on page 181.
Now, to find the pages Clint read prior to study hall.
<em>The time difference = 45 minutes - 20 minutes.</em>
<em> = 25 minutes.</em>
<em>Difference between the pages = 181 - 151</em>
<em> = 30 pages.</em>
If Clint is reading each page at same speed.
Then, in 25 minutes he can read = 30 pages.
So, in 1 minute he can read = 30 ÷ 25 = 1.2 pages.
Thus, in 20 minutes he can read
Now, number of pages Clint had read prior to study hall = 151 - 24
= 127 pages.
Therefore, the number of pages had Clint read prior to study hall were <u>127 pages</u>.

Answer:
The correlation coefficient between the variables number of calories in four meals and the cost of each meal is weak negative correlation.
Step-by-step explanation:
The data for the number of calories in four meals and the cost of each meal is as follows:
Number of Calories Cost of Meals
550 12
1250 11
780 13
650 10
Use the Excel function "CORREL(array1,array2)" to compute the correlation coefficient between the variables number of calories in four meals and the cost of each meal.
The correlation coefficient between the variables number of calories in four meals and the cost of each meal is -0.13.
The correlation coefficient between 0.00 to ±0.30 is considered as weak correlation coefficient.
The correlation value of -0.13 lies in the range 0 to -0.30. This implies that the correlation coefficient between the variables number of calories in four meals and the cost of each meal is weak negative correlation.
