Answer:
the quotient is $18.36
Step-by-step explanation:
$18,360/1000
$18.36
the quotient of $18,360÷1000 is equal to $18.36
Your answer is (1,-3) up one left 3.
Answer:
Option D is correct
Margin of error(to four decimal places) = 0.0414
Step-by-step explanation:
Given: p = 65% = 0.65 and n = 500
Error of margin (E) is given by:
For a confidence level of 95%,
Substitute the value of , p and n in the above formula to calculate error of margin (E) :
Simplify:
E = 0.0414082288551
Therefore, the margin of error(round to four decimal places) = 0.0414
Answer:
90% increase
Step-by-step explanation:
38-20 To find the increase in the wolves.
Then, you have to divide by the original amount. You will get 0.9
Multiply by 100 to get the percentage
You will get 90%
X^a/b is
. The way I memorise that is x^1/3 is the cubic root of x. Do you get it? In that case, x is raised to a power of 1 and the cubic root is practically has a power of 3.
In your example,
is practically square rooting each term then cubing them individually. Remember when square-rooting any index you halve it. I'll elaborate:
=
= 4
Then cube each,
= 64
and
=
As for the 2nd part: you must use the rules of indices.
So breaking the question up:
3 * 3 = 9
stays as is since the 2nd term does not contain x
now:
This makes your final answer look like this:
I hope that helped and good luck in your test!
