Step-by-step explanation:
Answer:
A, B, D
Step-by-step explanation:
A) y squared times y squared you just add the exponents
B) y^6/y^2 write it out as (y)(y)(y)(y)(y)(y)/(y)(y) then u cancel out two "y" from numerator and denominator and is left with y^4
C) is just 0 so its wrong
D) is the same process as B just cancel out 5 "y" from numerator and denominator and is left with y^4
E) is incorrect bc you need to add the exponents and you will get y^5 which is not equal to y^4 so yeah its wrong
So based on your diagram the following are the answers to your questions:
<span>(a) Use an equation to express the length y of the building in terms of the width x.
</span>- y(x) = 600/x
(b) If the walls cost $100 per running foot, use an equation to express the cost C of the <span>walls in terms of the width x.
- the answer is 6
</span>
Answer:
10 if distance from origin
Step-by-step explanation:
Answer: -3.0593
Step-by-step explanation:
The test statistic for the difference between two population mean (when population standard deviations 
are known ) is given by :-
where ,
= Sample sizes taken from two populations 1 and 2.
= Difference between two Sample mean.
= Standard deviations of populations 1 and 2.
As per given , we have
We assume that the data follows a normal distribution.
Then, the test statistic will be :-
Hence, the test statistic= -3.0593
