Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
Answer:
x = 31
Step-by-step explanation:
AC=BD
3x+7 = 131-x
Subtract 7 from both sides
3x = 124-x
Add x to 3x
4x = 124
Divide by 4
x = 31
Check:
3(31)+7 = 131 - 31
Mulitply 3 times 31 / subtract 131 and 31
93+7 = 100
Add 93 to 7
100 = 100

So, I think that you mean that
n²+m² is even? (the "plus" sign is missing, but I think this is correct).
this can only happen if either:
both n and m are even
or
both n and m are odd
That's because a sum of two expressions is even if either both or none of the expressions summed is even, and a power of a number is even only if the number is even too.
are those some of the options?
yes!
<span>n and m are even,- possible!
n and m are odd, -possible!
n+m is even, - possible; it would be the case i</span><span>f either both n and m are even or both n and m are odd n+m is odd,
so the option we'll choose is:
none of these are impossible </span><span />

As given, Carmela divides the mixed nuts into 3/10 kilogram bags so number of bags will be:
= 
= 5
Hence, answer is 5 bags.
