The manager of a fashionable restaurant open Wednesday through Saturday says that the restaurant does about 29 percent of its bu
RideAnS [48]

Answer: The seasonal relatives is calculated are as follows:

Step-by-step explanation:

Given that,

restaurant only open from Wednesday to Saturday,

  • 29 percent of its business on Friday
  • 31 percent on Saturday night
  • 21 percent on Thursday night.

∴ The remaining 19% of its business he does on Wednesday

Now, suppose that total production of sales in a given week be 'y'

So, average sales in a week = \frac{y}{4}

If we assume that y = 1

hence, average sales in a week = \frac{1}{4}

= 0.25

Now, we have to calculate the seasonal relatives,

that is,

=  \frac{Sales in a given day}{average sales in a week}

Wednesday:

= \frac{0.19}{0.25}

= 0.76

Thursday:

= \frac{0.21}{0.25}

= 0.84

Friday:

= \frac{0.29}{0.25}

= 1.16

Saturday:

= \frac{0.31}{0.25}

= 1.24

After spending some time looking for his pump, Marlon pumps up an uninflated balloon, pumping air into it at a constant rate. He
galina1969 [7]

Answer:

Graph D

Step-by-step explanation:

Initially, Marlon was looking for his pump. Thus, no air was pumped into the balloon until he got the pump. On getting the pump, he inflated the balloon with air at a constant rate, after which he tied it with a string to prevent the air from escaping.

The analysis is that, at the time he decided to inflate the balloon till he got a pump, the volume of air in the balloon is zero with respect to time. Pumping air at a steady rate into the balloon increases the volume of air flowing into it gradually and steadily.

When the volume got to a definite amount, he stopped pumping air and tied with a string. Thus, the volume of air in the balloon remains constant.
