Answer:
The Answers Are:
B. The variable h is the independent variable.
C. The number of hours worked causes a change in the number of dollars earned.
D. The variable d is the dependent variable.
Step-by-step explanation:
As you can see on the picture, the more hours you work, the more dollars you get.
d=19h
Answer with explanation:
Given : Sample size : n=425
The proportion of the population in Category A :
Significance level :
Critical value :
Since in normal distribution, the best estimate for proportion for population p is equals to the proportion for the sample.
Thus ,the best point estimate for p =0.27
Formula for margin of error :-
Hence, the margin of error = 0.0422
Now, the confidence interval for population proportion is given by :-
Hence, the 99% confidence interval for the proportion of the population in Category A given that 27% of a sample of 425 are in Category A =
C, the third choice, 8 to the third power (8^3) :)
Answer:
No extraneous solution
Step-by-step explanation:
We have the logarithmic equation given by,
i.e.
i.e.
i.e.
i.e.
i.e.
i.e.
So, the solution of the given equation is x=4.
Now, as we domain of square root function is x > 0 and also, the domain of logarithmic function is .
Therefore, the domain of the given function is x > 0.
We know that the extraneous solution is the solution which does not belong to the domain.
But as x=4 belongs to the domain x > 0.
Thus, x = 4 is not an extraneous solution.
Hence, this equation does not have any extraneous solution.
Answer:
Step-by-step explanation:
3x + 2 = 5x - 6
-2x + 2 = -6
-2x = -8
x = 4
3(4) + 2 = 12 + 2 = 14
5(4) - 6= 20 - 6 = 14 for GH
