Prove the following proposition: For all sets A, B, and C that are subsets of some universal set, if AnB = An C and Aº n B = Aº nC, then B = C.

Please answer b c and d

Two numbers are greater than 10 but less than 40. Their GCF is 17. What are the two numbers?

The following is a list of 6 measurements. 11, 17, 7, 8, 16, 20 Send data to calculator Suppose that these 6 measurements are respectively labeled x,, x,, ..., X6: Compute the following. i = 1 ?

legal case rested on whether a patent witness' signature was written on top of key text in a notebook or under the key text. The zinc measurements for three notebook ocations on a text line, on a witness line, and on the intersection of the witness and text line are provided in the table below. Complete parts a through c below. ext line Witness line 0.319 0.384 0.327 ntersection A. Ho: Hw-H₁0, Ha: Hw-₁0 OB. Ho: Hw-H₁0, Ha: Hw-₁ OC. Ho: HT-Hw=0, H₂: HT-H₁ <0 a O D. Ho: HT-HW = 0, H₂: HT-H₁0 Find the test statistic. 0.321 0.307 0.327 . Use a test (at a = 0.02) to compare the mean zinc measurement for the witness line with the mean for the intersection. Select the correct hypotheses below. t=(Round to two decimal places as needed.) Find the p-value. p-value = (Round to three decimal places as needed.) Choose the correct conclusion below.

There is a 3 percent error rate at a specii c point in a production process. If an inspector isplaced at this point, all the errors can be detected and eliminated. However, the inspectoris paid $8 per hour and can inspect units in the process at the rate of 30 per hour.If no inspector is used and defects are allowed to pass this point, there is a cost of $10per unit to correct the defect later on.Should an inspector be hired?

A Untitled document- G kji - Google Search I Spanish Trevor is Interested in purchasing the local hardware/sporting goads store in the small town of Dove Creek, Montana. After exemining accounting records for the past several years, he found that the store has been grossing over $850 per day about 65% of the business days It is open. Estimate the probability that the store will gross over $850 for the following. (Round your answers to three decimal places.) (a) at least 3 out of 5 business days 0.65 (b) at least 6 out of 10 business days 0.591 (c) fewer than 5 out of 10 business days 0.629 (d) fewer than 6 out of the next 20 business days 0.839 shake your confidence in the statement p = 0.65? Might it make you suspect that p is less than 0.65? Explain. If the outcome described in part (d) actually occurred, might Yes. This is unlikely to…

A research company is doing research on the number of Americans who have had COVID-19. They need to obtain a sample to estimate the population proportion of people who have had COVID-19. Based on a previous study at Stanford University, they believe the population proportion is approximately 13%. You would like to be 95% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required?
