If you are asking what x to the power of 2 minus x is as a mathematical expression, then your answer is:
= x^2 - x
If you are asking what another equivalent expression for x^2 - x is or if you want it in factorised form, then your answer is:
= x ( x - 1 )

Answer:
We need a sample size of at least 650
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.
In this problem:
We need a sample of size at least n
n is found when 
So
Rounding up
We need a sample size of at least 650
Answer:
Step-by-step explanation:
<em>Use of property</em>
- <em>log ab = log a + log b</em>
- <em>log a^b = b log a</em>
<h3>Given</h3>
<h3>Solution</h3>
- log 6^8 + log 6^z =
- log (6^8*6^z) =
- log (6^6z) =
- 6z log 6
48 of the pizzas would be cheese because you divide 80 by 5 and get 16 then multiply that by 3 to get 48
Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
