Answer:
B) -0.98
Step-by-step explanation:
Correlation coefficient is usually denoted with numbers ranging from 1 to -1. Automatically, this eliminates option C) as our possible answer, since -1.43 is outside the range.
The trend shown in the scatter plot describes a negative relationship because, as the values in the Y-axis decreases, the values at the X-axis increases. The possible correlation coefficient we are likely to get is one that is negative. This eliminates option A and option and option D is our possible correlation coefficient for the scatter plot given since both values are positive.
Option B) -0.98, best represents the correlation coefficient of the given scatter plot. Since the points on the scatter plot seem closely aligned on a straight line, a negative value if -0.98 is mostly the possible one to get.
Answer:
1618 minutes
Step-by-step explanation:
Jerold reads at a rate of 3 pages in 2 minutes. He as a 2427 page novel to read and a 906 page mystery book to read. How long will it take him to read his novel?
From the question above, the number of pages for his novel = 2427 pages
His reading rate =
3 pages = 2 minutes
Hence:
3 pages = 2 minutes
2427 pages = x minutes
Cross Multiply
3 pages × x = 2427pages × 2 minutes
x = 2427pages × 2 minutes/3 pages
x = 1618 minutes
It would take him 1618 minutes to read his 2427 paged novel
4.43
To find the mean (average) # of sick days taken, you add all the numbers, then divide by the number of employees.
31 ÷ 7 = 4.4285714286 or aprox. 4.43
Hey there!!
Let's take the number as x and y
Given,
The sum of x and y = 12
One number is 2 more than the other
Let's take y = x + 2
Equations
x + y = 12
As we know y = x + 2 , plug the value in
x + x + 2 = 12
2x + 2 = 12
Subtract 2 on both sides
2x = 10
Divide by 5 on both sides
x = 5
y = 2 + x
y = 7
The numbers are 5 and 7
Hope my answer helps!
