Answer:

P = 0.43h + 0.65p + 1.31d  represents the total profit, in dollars that the stand will make on a day when they sell h hot dogs, p pretzels, and d drinks

Step-by-step explanation:

Given :  The concession stand at a ballpark makes $0.43 profit from each hot dog sold. It also makes a profit of $0.65 from each pretzel sold and $1.31 from each drink sold

We have to find an expression that represents the total profit, in dollars that the stand will make on a day.

Let the stand sells h hot dogs, p pretzels, and d drinks on a day

Since profit of one hot dog is $ 0.43

So , profit of h hot dogs is $ 0.43h

also, profit of one pretzels is $ 0.65

So , profit of p pretzels is $ 0.65p

also, profit of one drink is $1.31

So , profit of d drinks  is $ 1.31d

Total profit of a day is the total profit he earned from selling each item.

thus, total profit is given by equation

P = 0.43h + 0.65p + 1.31d

Thus, P = 0.43h + 0.65p + 1.31d  represents the total profit, in dollars that the stand will make on a day when they sell h hot dogs, p pretzels, and d drinks

0.43h + 0.65p + 1.31d = c

explanation:
h stands for hotdogs, p for pretzels, and d for drinks. c represents the total cost. 
each price next to the variable describes the profit per item.

hope this helps! :D

J.J.Bean sells a wide variety of outdoor equipment and clothing. The company sells both through mail order and via the internet.

Answer:

99% confidence interval for the true mean difference between the mean amount of mail-order purchases and the mean amount of internet purchases is [$(-31.82) , $12.02].

Step-by-step explanation:

We are given that a random sample of 16 sales receipts for mail-order sales results in a mean sale amount of $74.50 with a standard deviation of $17.25.

A random sample of 9 sales receipts for internet sales results in a mean sale amount of $84.40 with a standard deviation of $21.25.

The pivotal quantity that will be used for constructing 99% confidence interval for true mean difference is given by;

                      P.Q.  =  \frac{(\bar X_1-\bar X_2)-(\mu_1-\mu_2)}{s_p \times \sqrt{\frac{1}{n_1}+\frac{1}{n_2} } }  ~ t__n_1_+_n_2_-_2

where, \bar X_1 = sample mean for mail-order sales = $74.50

\bar X_2 = sample mean for internet sales = $84.40

s_1 = sample standard deviation for mail-order purchases = $17.25

s_2 = sample standard deviation for internet purchases = $21.25

n_1 = sample of sales receipts for mail-order purchases = 16

n_2 = sample of sales receipts for internet purchases = 9

Also,  s_p =\sqrt{\frac{(n_1-1)\times s_1^{2}+(n_2-1)\times s_2^{2} }{n_1+n_2-2} }  =  \sqrt{\frac{(16-1)\times 17.25^{2}+(9-1)\times 21.25^{2} }{16+9-2} } = 18.74

The true mean difference between the mean amount of mail-order purchases and the mean amount of internet purchases is represented by (\mu_1-\mu_2).

Now, 99% confidence interval for (\mu_1-\mu_2) is given by;

             = (\bar X_1-\bar X_2) \pm t_(_\frac{\alpha}{2}_)  \times s_p \times \sqrt{\frac{1}{n_1} +\frac{1}{n_2}}

Here, the critical value of t at 0.5% level of significance and 23 degrees of freedom is given as 2.807.

          = (74.50-84.40) \pm (2.807  \times 18.74 \times \sqrt{\frac{1}{16} +\frac{1}{9}})

          = [$-31.82 , $12.02]

Hence, 99% confidence interval for the true mean difference between the mean amount of mail-order purchases and the mean amount of internet purchases is [$(-31.82) , $12.02].
