Add the number of boys that prefer to play inside and the number that prefer to play outside and then divide the ones that prefer inside by the total. The answer is 43.4 percent
Answer:
perimeter of a square= 4 times square root of area
I think it’s 25$ savings! Not completely sure... hope this helps!!!
The useful property in multiplication is that 1 raised to any number will always be equal to 1. Thus, if y is equal to 1, m and n are also equal to 1. But if y is greater than 1, then m and n would also, consequently, be greater than 1 but less than y. This is because the base number of an exponent must be less in value than the answer. However, if m and n are multiplied, then the product would be greater than 1 but still less than y.
Let's take an example to prove this point.
Suppose y=5, then
m = ⁴√5 = 1.49
n = ∛5 = 1.7
Then, m×n = 2.5 which is less than y but greater than 1
Answer:
A sample of 217 is needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
If the population standard deviation is $3,750 how large should the sample be if margin of error is $500
We have that 
.
We need a sample of n, and n is found when 
. So
Rounding up
A sample of 217 is needed.
