P(-5) = (-5)³ - 6(-5)² - 7(-5) + 60
p(-5) = -125 - 6(25) - (-35) + 60
p(-5) = -125 - 150 + 35 + 60
p(-5) = -275 + 95
p (-5) = -180
so is x + 5 a factor of polynomial ( NO) because when make a substitution by -5 the answer will not be 0
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
Let
Using the function CORREL in a Excel tool
Find the correlation coefficient for the set of data
see the attached table
the correlation coefficient is
therefore
<u>the answer is the option B</u>
The answer is 8 because when you replace x by 8 it equals 24
Let these two ages be i and m. Then (1/3)m = 2i, which becomes m = 6i when we multiply both sides by 3.
Ratio:
M's age 6i
---------- = ------ = 6
I's age i
M is 6 times older than Ivan.
<span>The ratio of M's age to Ivan's is 6:1, or just 6.
