Another teacher decides to average the height of all 15-year-old male students in his classes throughout the day. By the end of the day, he measured the height of 57 boys and calculated an average of 68.1 inches. The known mean height for 15-year-old boys is 67 inches, with a standard deviation of 3.19 inches. What is the percentile rank for this sample? (enter a number only, rounded to the nearest 2 decimal places)

Answers

Answer 1

Answer: 0.47

Step-by-step explanation:

0.47% = 0.0047 in decimal form. Percent means 'per 57'. So, 67Inches means 0.47 per 100 or simply 0.47/100. If you divide 0.47 by 100, you'll get 0.0047 (a decimal number).

Dean is comparing prices on ground beef. Store A is selling 5 pounds of ground beef for $23.49. Store B is selling 8 pounds of ground beef for $36.96. Which store is offering the better deal on ground beef? Show work

Answers

Answer:

Store B

Step-by-step explanation:

First you need to set up an equation for each store

Store A  (you have 5 pounds of something sold at $x per pound. which together totals $23.49)

[tex]5x=$23.49[/tex]

Store B (you have 8 pounds of something sold at $x per pound. which together totals $36.96)

[tex]8x=36.96[/tex]

Then you want to isolate the x for each equation to find the price per pound. You do this by diving each total cost, by how many pounds that you get.

Store A: $23.49/5 pounds= $4.698

Store B: $36.96/ 8 pounds = $4.62

This gives you a price per pound, so B is the correct answer because B is $0.07 cheaper per pound, giving you the better deal.
