we know that
<u>The correlation coefficient</u> is a number between and
that represent the linear dependence of two variables or sets of data
Using the function CORREL in a excel tool, calculate the correlation coefficient (r)
see the attached table
the correlation coefficient for the data in the table is equal to
therefore
<u>the answer is</u>
Answer:
Step-by-step explanation:
Let
y -----> gallons of water remaining in the barrel
x-----> number of minutes elapsed
we know that
Water leaks out of the barrel at a rate of 1 gallon every 10 minutes
so
The linear equation that represent this situation is
The graph in the attached figure
Answer:
3.5 cm
Step-by-step explanation:
Length of an arc is a "part" of the circumference of a circle.
The circumference is the perimeter of the circle. Formula is:
Where
C is circumference
d is diameter
Given diameter is 16, the circumference would be:
Now, the arc is 25 degrees, which is 25/360 th of the circle's circumference [recall, there is 360 degrees in whole circle].
So, we multiply the circumference we got by (25/360) to get our answer:
Minor Arc JH = 3.5 cm
