Write an expression that represents the height of a tree that begins at 2 feet and increases by 4 feet per year. Let y represent the number of years. PLEASE HELP ME
Answers
Answer: 2+4y
Explanation: The height of the tree increases by 4 feet per year, so we know to multiply 4 by the number of years to find its height. The initial height of the tree is 2, so we add 2 to 4y.
Example: The height of the tree in 6 years 2+4y 2+4*6 =2+24 =26
I hope this helps!
Answer:
2+4y
Step-by-step explanation:
The Museum of Science in Boston has an exhibit in which metal balls drop down a chute, bounce around, and wind up in one of 21 bins. After 1000 balls have dropped, the heights within the bins clearly follow a bell-shaped curve. If the standard deviation is 3 bins, approximately how many balls are in bins 1 through 7?A) 100 B) 160 C) 50 C) 330
Answers
if you have 21 bins then the 'middle bin' is bin 11 (starting at 1)So the 'mean' of this distribution is 11.The SD is 3so using the above calculator (or your own tables ) you get that the probability of a ball being in bin 7 or less is .091
A is you answer
A.100 so make sure you put your answer
Juana’s dad gave her an exponentially increasing allowance as an experiment. On the first day, he gave her 1¢.

A store uses the expression –2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from $9 to $15. Which price gives the store the maximum amount of revenue, and what is the maximum revenue? (Revenue = price mc023-1.jpg number of backpacks.) $9.00 per backpack gives the maximum revenue; the maximum revenue is $32.00. $12.00 per backpack gives the maximum revenue; the maximum revenue is $312.00. $12.50 per backpack gives the maximum revenue; the maximum revenue is $312.50. $15.00 per backpack gives the maximum revenue; the maximum revenue is $20.00.
Answers
Revenue = price * number of backpacks number of backpacks = -2p + 50
