After you combine like terms you will get 5p - 9m.
-3p + 8p is the same thing as 8p - 3, so you get 5p.
-2m + (-7m) is -9m
-3p and 8p are like terms.
-2m and -7m are also like terms.
Answer:
3(x-1)x(3x+1)
Step-by-step explanation:
The function of f(x)=-x+4x-3 is 3x-3. I hope this helps. :)
Answer:
Now we can calculate the p value based on the alternative hypothesis with this probability:
The p value is very low compared to the significance level of
then we can reject the null hypothesis and we can conclude that the true proportion of people liberal is higher than 0.24
Step-by-step explanation:
Information given
n=200 represent the random sample taken
X=75 represent the number of people Liberal
estimated proportion of people liberal
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We want to verify if the true proportion of adults liberal is higher than 0.24:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Now we can calculate the p value based on the alternative hypothesis with this probability:
The p value is very low compared to the significance level of
then we can reject the null hypothesis and we can conclude that the true proportion of people liberal is higher than 0.24
Answer:
10 sides.
Step-by-step explanation:
Two same interior angles + 72 degrees = 360.
Thus, the interior angle of the polygon is
.
The formula to find the interior angle of a polygon is 

Multiply both sides by n:


Expand:

Add 360 to both sides:


Subtract 144n from both sides:


Divide both sides by 36:
