The first thing you want to do is get them all into decimal format. You can do this to fractions by dividing the denominator from the numerator. then you organize the decimals into least to greatest.
0.25; 0.479; 0.5; 0.5625
0.25; 23/48; 0.5; 9/16
Hope it helped.
When you have multiplying with same base, you add the power, for example here : z^6 * z^3 = z^(6+3) = z^9.
When you have dividing with the same base, you substract it, for example here : z^9/z^4 = z^(9-4) = z^5.
Answer:
x = 
Step-by-step explanation:
- 18 + 64 = 0
+ 46 = 0
= - 46
x =
Answer:
A sample size of at least 737 specimens is required.
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 width M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So:
A sample size of at least 737 specimens is required.
9(x + 3) = 8
9x + 27 = 8
9x = -19
Answer: -19/9
