Answer:
-3y^2 + y + 100
Step-by-step explanation:
Combine like terms.
-3y+4y = 1y or "y"
Add "y" back into the equation.
-3y^2 + y + 100
The equation cannot be simplified any further.
I hope this helped!
According to the hypothesis test, the option that gives the most appropriate method for creating such an estimate is:
A one-sample z-interval for a population proportion.
<h3>What is the hypothesis test?</h3>
He will test if there is enough support to build a new middle school, that is, if the population proportion that supports the building of a new middle school is greater than a threshold.
Only one sample is taken from the district residents, hence the correct option is:

Answer:
1/3
Step-by-step explanation:
probability= no. of objects/no. of total number
= 3/9
=1/3
Answer:
z=63°{vertically opposite angle}
now,
z+10x+97=18o°{straight angle}
63+10x+97=180°
10x=180-133
x=<u>2</u><u>0</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>10
x=2
