Answer:
No solution
Step-by-step explanation:
Actually, you have only one equation here. We will solve it for x.
Performing the indicated multiplication, we obtain:
10-2(2x+1)=4(x-2) => 10 - 4x - 2 = 4x - 8, or 10 - 2 = -8. This can never be true, so this equation has no solution.
The decimal number is 0.9
Answer:
a) 
b) The should sample at least 293 small claims.
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 , which means that the answer of question a is z = 1.645.
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.
(b) If the group wants their estimate to have a maximum error of $12, how many small claims should they sample?
They should sample at least n small claims, in which n is found when
. So
The should sample at least 293 small claims.
Answer:
Hi there!
Your answer is:
It will take 2.2 months for both gyms to be the same amount of money!
Step-by-step explanation:
Fitness 19:
39+ 17x
Anytime Fitness:
50+ 12x
Put them equal to each other:
39+17x = 50+12x
-12x
39+5x = 50
-39
5x = 11
/5
x= 2.2 months
39+17(2.2)= 76.4$
50+12(2.2)= 76.4$
Hope this helps!
5 million is greater than 152000 because 5 million = 5,000,000 and that is larger than 152000 (only 152 thousand; 5 million is 5000 thousands)
