Answer:
1/2
Step-by-step explanation:
(1/16)^x
Let x = 1/4
(1/16)^ 1/4
Rewriting 16 as 2^4
(1/2^4)^ 1/4
We know that 1 / a^b = a^-b
(2 ^ -4)^ 1/4
We know that a^b^c = a^(b*c)
2^(-4*1/4)
2^-1
We know that a^-b = 1/ a^b
2^-1 = 1/2^1 = 1/2
All methods are supposed to be correct in most if not all situations and it should not matter if you use a different method given the options
Answer:
The sample size to obtain the desired margin of error is 160.
Step-by-step explanation:
The Margin of Error is given as
Rearranging this equation in terms of n gives
Now the Margin of Error is reduced by 2 so the new M_2 is given as M/2 so the value of n_2 is calculated as
As n is given as 40 so the new sample size is given as
So the sample size to obtain the desired margin of error is 160.
Answer: 16
Step-by-step explanation:
Let's complete the square.
It will be cost $ 42.39 for 27 slices of pizza
<h3>
Further Explanation</h3>
A slice of pizza = $1.57
27 slices of pizza = the number of pizza x price/slice
= 27 x 1.57
We are going to use standard algorithm to solve this multiplication
1.57 ⇒ 2 decimal places
<u> 27</u> x ⇒ 0 decimal place
1099
<u> 314 </u>+
42.39 ⇒ 2 decimal places
In decimal number multiplication, the process is the same with the whole number multiplication. Only always remember when to put the decimal point in the answer.
