Ok, so to increase 200 by 18%, you want to know how much is 1% of 200. So, in order to figure this out, you want to divide 200 by 100, to get 2. So, you know that 2 is 1% of 200. Now, to increase 200 b 18%, you will want to multiply 18 by 2, to get 26. So, the final answer is 236.
Answer:
5(x-y)/6
Step-by-step explanation:
(4x-y)/3 - (x+y)/2
We have to find the Least common multiple to simplify the operation.
(The Least common multiple of 3 and 2 = 3*2 = 6)
[2(4x-y)-3(x+y)]/6
(8x-2y-3x-3y)/6
5x-5y/6
5(x-y)/6
The rule of subtracting the fraction, including the constant, is to do in a simplification method.
Therefore, the answer is 5(x-y)/6
Answer:
A sample size of 385 is needed.
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 
.
That is z with a pvalue of 
, so Z = 1.96.
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.
You feel that a reasonable estimate of the standard deviation is 10.0 hours.
This means that 
What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?
A sample size of n is needed. n is found when M = 1. So
Rounding up:
A sample size of 385 is needed.
Answer:
the answer is c
Step-by-step explanation:
Answer:
34
Step-by-step explanation:
Substitute values given into expression and simplify :
5(2) + 6(4) =
10 + 24 =
34
Hope this helped and have a good day
