Amanufacturer produces two models of toy airplanes. it takes the manufacturer 32 minutes to assemble model a and 8 minutes to package it. it takes the manufacturer 20 minutes to assemble model b and 10 minutes to package it. in a given week, the total available time for assembling is 3200 minutes, and the total available time for packaging is 960 minutes. model a earns a profit of $10 for each unit sold and model b earns a profit of $8 for each unit sold. assuming the manufacturer is able to sell as many models as it makes, how many units of each model should be produced to maximize the profit for the given week?

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
