A square has an area of 289 sq cm. what is the length of one side

1 answer:

5 0

For this problem you can do it one of two ways. The first way would be simply take the square root because the area of a square is one side squared. The other way using the same rule would be to go up from a reasonable number and square it, if that is not the number you are looking for add 1 to the original number and square it again. if you cannot square and square root in your head, you should be allowed to use a calculator to get the answer or 17 as the length of a side.

Lim->infinity 4n^2/n^2+10000n

dybincka [34]

let P(n)=4n² / n²+10000n
when n ----------> infinity, the main rule is as follow
lim P(n)=4n² / n²+10000n = lim P(n)=4n² / n²= lim 4= 4
n ----------> infinity n ----------> infinity n ----------> infinity
finally

Lim->infinity 4n^2/n^2+10000n = 4

The value of homes sold in Hampton VA are normally distributed with a mean of $200,000 and a standard deviation of $10,000. If 1

LenKa [72]

Answer:

84%

Step-by-step explanation:

What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.

We have that z is equal to:

z = (x - m) / (sd)

x is the value to evaluate, m the mean, sd the standard deviation

So for 190000 we have:

z = (190000 - 200000) / (10000)

z = -1

and this value represents 0.1587

for 230000 we have:

z = (230000 - 200000) / (10000)

z = 3

and this value represents 0.9987

we subtract:

0.9987 - 0.1587 = 0.84

Which means that it represents 84% of the houses
