(iii) The standard deviation of Y
Answer:
Length of a Road
Step-by-step explanation: No man that has ever lived (Well unless they're a nephilim or smth) is over a mile tall. Swimming pools and buildings aren't usually big enough to be measured in miles unless they're either a skyscraper or a Wisconsin water park attraction.
Hi there!
First, we need to find the length of the stage. We can do this by plugging in our known values and solving for the unknown value.
WORK:
252 = 9 x l
l = 28
Next, we know that there are two lengths and two widths total. So all we need to do is to add two lengths plus to widths to find the perimeter.
WORK:
2(28) + 2(9) = P
56 + 18 = P
P = 74 feet^2
Hope this helps!! :)

Answer:
The answer is 4z^2 + 7z
Step-by-step explanation:
7z + 4z^2 +6 - 6
So, just combine like term which is 6 - 6 = 0
So, the remaining is 4z^2 + 7z that cannot be simplified anymore
