Answer:
A one-sided, two-sample t-test
Step-by-step explanation:
In the context, the values of the population standard deviations are not provided, therefore we have to use the two sample t tests for the difference between the two population means. This claim for the hypothesis or the alternative hypothesis is given as the average selling price is more for the first group of the sample size of 21 as compared to the other group of the sample size of 87. Therefore, we perform an one sided test or the upper tailed test.

Answer:

Step-by-step explanation:
For this case we have the following profit function:

And we are interested on find the profit after selling 700 pretzels, so we just need to replace X=700 into the profit function like this:

The profit function is on the figure attached. We see that for 0<X<217 we have negative profits, and for X>217 we will have positive values for the profit. And also we can see that for X=700 we have a profit of approximately 169.
Answer:
36/40, 47/101, 192
Step-by-step explanation:
(a)The numerator (top number of the fraction) is adding up by odd numbers in order.
From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.
The next number to add would logically be 11. So from 25/40 you would go to 36/40.
36/40 is your next fraction.
(b)
3+4=7,4+7=11,7+11=18,11+18=29,18+29=47
(c) 1*2=2,2*2=4,2*4=8,4*8=32,8*32=256,32*256=8,192
