Answer:
Original claim is 
Opposite claim is 
Null and alternative hypotheses:


Significance level: 0.01
Test statistic:
We can use TI-84 calculator to find the test statistic and P-value. The steps are as follows:
Press STAT and the scroll right to TESTS
Scroll down to 2-SampTTest... and scroll to stats.
Enter below information.







Pooled: Yes
Calculate.
The output is in the attachment.
Therefore, the test statistic is:

P-value: 0.4412
Reject or fail to reject: Fail to reject
Final Conclusion: Since the p-value is greater than the significance level, we, therefore, fail to reject the null hypothesis and conclude that the there is sufficient evidence to support the claim that the samples are from populations with the same mean.
Answer: x=−5
Step-by-step explanation:
8x+32=5x−3−4x
8x+32=x−3
8x+32−x=−3
7x+32=−3
7x=−3−32
7x=−35
x=- 35/7
x=−5
It is 12 since 1/6=6^-1=6
implies 2*6=12
Answer:
3, 15
Step-by-step explanation:
1/10 of a unit also just means dividing by 10. 1/2 is just dividing by 2. Hope this helped!
The first thing we must do is find the amount of land that will be used for the 120 lots.
We must remember that 10% of the land will not be used for the lots.
We have then:

Then, we must consider the following conversion of units:

Applying the conversion we have:

Then, the amount of square feet for each lot is given by:
Answer:
There will be 32670 square feet in each lot.
