Answer:
The correct option is;
C. Quadratic
Step-by-step explanation:
The given information are;
The quantity of corn Farmer Joe has to sell = 1,000 bushels
The present market price for corn = $5.00 a bushel
The amount by which he expects the market price to rise per week =$0.15
The number of bushels lost to spoilage per week = 10
Therefore, we have;
The value of the corn = Amount of corn left × Price of corn
The price of the corn per bushel with time = 5 + 0.15×t
The amount of corn left = 1000 - 10×t
Where;
t = Time in minutes
Therefore, the total value of corn = (1000 - 10×t)×(5 + 0.15×t) = -1.5·t²+100·t+5000 which is a quadratic model.
Therefore, the correct option is a quadratic model.

Answer:
40 miles.
Step-by-step explanation:
Given that the cost of renting a car in Hertz is $ 15 per day plus $ 0.50 for each mile traveled, while in Enterprise the cost is $ 25 per day plus $ 0.25 per mile traveled, to determine how many miles should be traveled to incur the same expenditure in both companies the following calculation must be made:
25 - 15 = 10
0.50 - 025 = 0.25
10 / 0.25 = 40
Therefore, to incur the same cost, 40 miles must be traveled, which is verified with the following calculation:
25 + 0.25 x 40 = 35
15 + 0.50 x 40 = 35
Answer:
0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 8 minutes
Standard Deviation, σ = 2.5 minutes
Sample size, n = 25
We are given that the distribution of time spent is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(sample mean is between 7.8 and 8.2 minutes)
0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
Y = a * b^x
18 = a * b²
60.75 = a * b^5
60.75 = a * b² * b³
60.75 = 18 b³
b³ = 60.75 : 18
b³ = 3.375
b = ∛ 3.375
b = 1.5
18 = a * 1.5²
18 = a * 2.25
a = 18 : 2.25
a = 8
Answer:
y = 8 * 1.5^x
