\left[y \right] = \left[ -5\right][y]=[−5] totally answer
24 since .25 times 4 = 1 so try 6 times 4 and it equals 24
Answer:
Correct choice is (C). 
.
Step-by-step explanation:
Given expression is 
.
Now we need to simplify that then select the correct difference value from the given choices.
negative times negative is positive
Combine like terms because variable z has same exponent.
Hence correct choice is (C). .
Answer:
Answer = √(0.301 × 0.699 / 83) ≈ 0.050
A 68 percent confidence interval for the proportion of persons who work less than 40 hours per week is (0.251, 0.351), or equivalently (25.1%, 35.1%)
Step-by-step explanation:
√(0.301 × 0.699 / 83) ≈ 0.050
We have a large sample size of n = 83 respondents. Let p be the true proportion of persons who work less than 40 hours per week. A point estimate of p is because about 30.1 percent of the sample work less than 40 hours per week. We can estimate the standard deviation of as . A confidence interval is given by , then, a 68% confidence interval is , i.e., , i.e., (0.251, 0.351). is the value that satisfies that there is an area of 0.16 above this and under the standard normal curve.The standard error for a proportion is √(pq/n), where q=1−p.
Hope this answer helps you :)
Have a great day

Answer:
The domain must be [1, ∞).
Step-by-step explanation:
To do this we need to ensure that the x-1 is not negative.
That is x must be >= 1.
