Mark wants to be a chef someday and would like to start learning to grow his own
ingredients in a garden. His mom gives him 12 square feet of space in the back yard to plant
a garden. He marks off % of it to save for a tomato plant and has the rest to use for onions.
Each onion bulb needs square feet of room to grow. How many onion bulbs can he
plant?
Answers
The area of the space available for onions is:n12 square feet - 0.12x square feet. number of onion bulbs Mark can plant is: (12 - 0.12x) / y
What is percentage?
Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".
Mark has marked off a certain percentage of the 12 square feet to save for a tomato plant, which means the remaining space will be used for onions.
Let's say Mark marks off x% of the space for the tomato plant. That means he will have (100-x)% of the space for onions.
The area of the space reserved for the tomato plant is:
12 square feet x (x/100) = 0.12x square feet
The area of the space available for onions is:
12 square feet - 0.12x square feet
Let's say each onion bulb needs y square feet of room to grow. Mark can plant as many onion bulbs as can fit in the remaining space, which is:
(12 square feet - 0.12x square feet) / y
So the number of onion bulbs Mark can plant is:
(12 - 0.12x) / y.

Answer:
(A)
N(T(t)) = 416t² - 242.4 - 135.16
(B)
Time = 27.30 hours
Step-by-step explanation:
Given
N(T) = 26T² - 123T + 25
T(t) = 4t + 1.2
Solving for the composite function.
Substitute T for 4t + 1.2 in N(T)
N(T(t)) = 26(4t + 1.2)² - 123(4t + 1.2) + 25
N(T(t)) = 26(4t+1.2)(4t + 1.2) - 123(4t + 1.2) + 25
N(T(t)) = 26(16t² + 9.6t + 1.44) - 492t - 147.6 + 25
N(T(t)) = 416t² + 249.6t + 37.44 - 492t - 172.6
N(T(t)) = 416t² + 249.6t - 492t + 37.44 - 172.6
N(T(t)) = 416t² - 242.4 - 135.16
Solving for time.
We have that
N(T) = 16044
N(T) = 26T² - 123T + 25
This gives
16044 = 26T² - 123T + 25
26T² - 123T + 25 - 16044 = 0
26T² - 123T - 16019 = 0
Solve by quadratic, we have.
T = 27.299506396472
Or
T = -22.568737165703
Since time can't be negative
T = 27.299506396472
T = 27.30 (approximately)
An instructor is administering a final examination. She tells her class that she with give an A grade to the 10% of the students who earns the highest marks. Past experience with the same examination has yielded grades that are normally distributed with a mean of 70 and a standard deviation of 10. If present class runs true to form, what numerical score would a student need to earn an A grade?
Answers
To earn an A grade, a student needs to score at least 82.8 , calculated using the inverse normal cumulative distribution function with a mean of 70, a standard deviation of 10, and a 10th percentile of 0.10.
Given that the grades are normally distributed with a mean of 70 and a standard deviation of 10.
We need to find the score which is at the 10th percentile of the distribution.
Using the standard normal distribution table, we can find the z-score that corresponds to the 10th percentile.
From the table, we can see that the z-score is approximately -1.28.
Using the formula for standardizing a normal distribution:
z = (x - μ) / σ
where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.
Substituting the given values, we have:
-1.28 = (x - 70) / 10
Solving for x, we get:
x = (-1.28 * 10) + 70
x = 82.8
Therefore, a student would need to earn a score of approximately 82.8 to receive an A grade.

C Ask 10 people from each grade level at Allison's school how many games they have on their phones.
D Ask 5 teenagers from 20 different countries how many games they have on their phones.
Answers
The answer choice which gives the best-example of the "random-sample" is (c) Ask 10 people from each "grade-level" at Allison's school about how many games they have on their phones.
A "Random-Sample" is a subset of a larger population which is chosen in such a way that each member of the population has an equal chance of being selected.
The Option (c) : gives the best example of a random sample that Allison could use to help answer her question. By asking 10 people from each grade level at her school, Allison can obtain a sample that includes a variety of ages, genders, and backgrounds.
This can help to ensure that the sample is representative of the population she is interested in studying.
Option (a) : is not a random sample because it only includes teenagers who happen to be at the grocery store at the time Allison is conducting her survey. This may not represent entire population of teenagers at her school.
Option (b) : is not a random sample either because it only includes people who happen to be at the library on Saturday morning. This may not be representative of the entire population of teenagers at her school.
Option (d) : is not a random sample because it only includes teenagers from 20 different countries. This may not be representative of the population of teenagers at Allison's school or in her local area.
Therefore, the correct option is (c).

You roll a 6-sided die.
What is P(not divisor of 6)?
Write your answer as a fraction or whole number.
Answers
1/3
Step-by-step explanation:The notation P(x) is used to describe the probability of event x occurring.
Divisors
Before we can do the probability question, we need to find the divisors of 6. Divisors are numbers that can evenly divide another number. The factors and divisors of a number are the same. So, 6 has 4 divisors:
1, 2, 3, and 6All of these values are on a 6-sided dice. So, in this probability question, there are 4 unsuccessful outcomes.
Probability
The probability of a simple event is the number of successful outcomes divided by the number of possible outcomes. In this situation, there are 6 possible outcomes, each side of the dice. Four of these outcomes do not satisfy the given condition (not a divisor of 6). Thus, there are 2 successful outcomes.
\(\frac{2}{6} =\frac{1}{3}\)The probability of rolling a number that is not a divisor of 6 is 1/3.
An object is launched from ground directly upward. The height (in metres) of the object after time t (in seconds) is given by h=−4.9t^2 +39.2t (a) When will the object fall back to the ground? (b) Find the maximum height the object reaches. (c) For what values of t the height formula is applicable?
Answers
Answer:
see below
Step-by-step explanation:
h=−4.9t^2 +39.2t
When will if fall back to the ground
When will h=0
0 =−4.9t^2 +39.2t
Factor out a -t
0 = -t (4.9t -39.2)
Using the zero product property
-t =0 4.9t - 39.2 =0
t =0 4.9t = 39.2
t =39.2 /4.9
t =8
It will reach the ground again at 8 seconds
The maximum height is halfway between the zeros
(0+8)/2 = 4
It will reach the max height at 4 seconds, substituting this in to find the max height
h=−4.9 (4)^2 +39.2(4)
h = 78.4 meters
This will only be applicable between t=0 and t=8 seconds

A car is purchased for $19,500. After each year, the resale value decreases by 20%. What will the resale value be after 3 years? Use the calculator provided and round your answer to the nearest dollar.
Answers
The resale value of the car after 3 years is $9,984.
How to find the resale value after 3 years?Since the resale value decreases by 20%. Thus, the resale value of the car will be 80% of its original value.
After the first year, the resale value of the car will be 80% of its original value:
Resale value after 1 year = 80/100 * $19,500 = $15,600
After the second year, the resale value of the car will be 80% of its value after the first year:
Resale value after 2 years = 80/100 * $15,600 = $12,480
After the third year, the resale value of the car will be 80% of its value after the second year:
Resale value after 3 years = 80/100 * $12,480 = $9,984
Therefore, the resale value of the car after 3 years will be $9,984.
