What suggestions do you have to promote the relationship and mutual understanding between Baby Boomers and Gen Y?
Out of 600 people sampled, 528 had children. Based on this, construct a 95% confidence interval for the true population proportion of people with children.\ Preliminary:\ a. Is it safe to assume that $n \leq 5\%$ of all people with children?\nYes\nNo\ b. Verify $n\hat{p}(1-\hat{p}) \geq 10$. Round your answer to one decimal place.\ $n\hat{p}(1-\hat{p}) =$\ Confidence Interval: What is the 95% confidence interval to estimate the population proportion?\nRound your answer to three decimal places.\ $\text{____} < p < \text{____}$
Suppose table R has 3 rows and table S has 4 rows. What is the maximum number of rows in the natural join of R and S?
Extreme Wreaths, Inc., makes wreaths in batch sizes of 15 at a time. The cutting and assembly process takes 10 minutes per wreath, and the decorating process time is 7 minutes per wreath. It takes 5 minutes to move the wreaths from the cutting and assembly process to the decorating process. In an effort to improve the lead time, the company has tried reducing the batch size to 10 units. The new process is as follows: cutting and assembly processโ5 minutes. The decorating process is still 7 minutes per wreath. It takes 5 minutes to move the wreaths from the cutting and assembly process to the decorating process. a. Compute the value-added, non-value-added, and total lead times of the wreath process for both the old and new manufacturing processes. b. Compute the value-added ratio for both the old and new processes. Round to one decimal place.
Please solve questions #8, #9, and #10. In Exercises 7-12, a function z=f(x,y) is given. Find Vf. 7. f(x,y) = -xy + xy + xy 8. f(x,y) = sin(x)cos(y) 9. f(x,y) = x^2 + y^2 + 1 10. f(x,y) = 4x + 3y
Given the equation below, calculate the number of moles of propane ($C_3H_8$) that are needed to make 11.1 moles of carbon dioxide. Give your answer to 2 decimal places $C_3H_8 (g) + 5 O_2 (g) \rightarrow 3 CO_2 (g) + 4 H_2O (l)$
Two similar heat exchangers are arranged as shown in the figure below. The inlet temperature of the hot fluid is 80ยฐC ($T_{hi}$) while the inlet temperature of the cold fluid is 20ยฐC ($T_{ci}$). Hot fluid has the lowest heat capacity among the two fluids. The heat capacity ratio of each heat exchanger as well as the combination is 0.3. The effectiveness of the combination of two heat exchangers is 0.6. There is good mixing for each of the fluids inside the heat exchanger but non mixing of each of the fluids outside the heat exchanger. Determine the hot fluid temperature difference in the second heat exchanger.
