Answer:
33
Step-by-step explanation:
35 take away 1 is 34 take away one more its 33
You would write it as (1/10^12)
any negative exponent does the same thing
ex: x^-1 turns into (1/x^1)
Answer:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
Step-by-step explanation:
A confidence interval at the level of x% for a proportion being between a and b means that we are x% sure that the true proportion of the population is between a and b.
In this problem, we have that:
95% C.I is (0.5, 0.66)
Interpretation: 95% confident that the true proportion is between 0.5 and 0.66.
The correct answer is:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
We have the following inequations:
x-6> -14
x / 4 <0
We solve each one separately:
For x-6> -14:
x-6> -14
x> -14 + 6
x> -8
For x / 4 <0:
x / 4 <0
x <4 * 0
x <0
The final result is the following compound inequality:
-8 <x <0
Answer:
-8 <x <0
Yes it is correct because if you multiply 3 by the value of x(7) and add 4 your answer is 25.
