Answer:
12 pounds
Explanation:
If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.
Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.
So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.
Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.
2 inches per minute. Just divide the total amount of inchs by the number of minutes and you have your unit rate.
Your equation is already in one of the standard form. Specifically, the slope intercept form.
y=mx + b.
m is the slope, b is the intercept.
Start with the intercept y= 2, the point (0,2).
A slope of 3 would give you (1,5) as a second point for your line.
Get a ruler and draw a line through the two points.
Perimeter of the arc = 1/2 πD
Perimeter of the arc = 1/2 x π x (16 x 2)
Perimeter of the arc = 50.27mm (Nearest hundredth)
Perimeter of the figure = 50.27 + 20 + 20 = 90.27mm
------------------------------------------------------
Answer: Perimeter = 90.27 mm

Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500
Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.
68%=0.68
0.68*288= 195.84≈196
Answer is d) 196
