Answer:
$208.33
Step-by-step explanation:
Julie has to make the down payment which is 25% of $60000 after saving for 6 years.
Therefore, Julie has to save a total of dollars.
And Julie has to save it for the duration of 6 years i.e. (6 × 12) = 72 months.
Hence, Julie has to save dollars every month to make the down payment after 6 years. (Answer)
Answer:
Since the calculated values is lower than the critical value we have enough evidence to reject the null hypothesis at the significance level of 2.5% and we can say that the true mean is lower than 36 years old
Step-by-step explanation:
Data given
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
System of hypothesis
We need to conduct a hypothesis in order to check if the true mean is less than 36 years old, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
And replacing we got:
Now we can calculate the critical value but first we need to find the degreed of freedom:
So we need to find a critical value in the t distribution with df =21 who accumulates 0.025 of the area in the left and we got:
Since the calculated values is lower than the critical value we have enough evidence to reject the null hypothesis at the significance level of 2.5% and we can say that the true mean is lower than 36 years old
We know that the equation of the line is in the form . To find b, we can use the fact that (6,-5) lies on the line, meaning that both sides of the equation are equal when x=6 and y=-5.
Hence, the equation of the line is , and its graph looks something like follows.
The percent equation is
n=2.8%×45 or n=0.028×45. where n is the unknown number.
the proportion would be
n/45=2.8/100
the answer is 1.26
Answer:
Step-by-step explanation:
3 over 2/3 → 3/1 divided by 2/3 → 3/1 x 3/2 (do keep change flip)
once you multiply you'll get 9/2.
