Answer:
a) sample size ≥ 30
b) 0.0017
Step-by-step explanation:
a) The central limit theorem states that for population with mean μ and standard deviation σ and take sufficiently large random samples from the population. This will hold provided the sample size is sufficiently large (usually n > 30) for a normal population.
Therefore the sample size should be greater or equal to 30 i.e n ≥ 30.
b) Given that n = 45, μ = 11.4 minutes and σ = 3.2 minutes, the z score (z) is given by the equation:
[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]
Substituting values to get:
[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }= \frac{10-11.4}{\frac{3.2}{\sqrt{45} } }=-2.93[/tex]
Using the z table:
P(x < 10) = P(z < -2.93) = 0.0017
the probability that a random sample of n=45 oil changes results in a sample mean time of less than 10 minutes is 0.0017
For part (a), a sample size larger than 30 would be sufficient for using the normal model. For part (b), we'd use the standard error and z-score to find the corresponding probability for the sample mean time being under 10 minutes with a sample size of 45.
Explanation:The questions revolve around the normal distribution model, which is a concept in Statistics, and the sample size needed to use the normal model to make inferences about a population (in this case, the duration of oil changes). For part (a), we must note that the Central Limit Theorem allows us to assume the distribution of sample means will approximate a normal distribution if the sample size is large enough (mostly, n > 30 is sufficient).
Thus, for this particular scenario, a sample size greater than 30 would be adequate. For part (b), using the standard error (standard deviation / sqrt(n)) with n = 45, we can find the z score = (X - μ) / standard error, where X is 10. We consult a normal distribution table or use software to find the probability associated with this z-score, which would be the answer.

Question:
59 Revenue. The revenue (in dollars) from the sale of x infant car seats for infants is given by
R(x) =60·x - 0.025·x² 0 ≤ x ≤ 2400
(A) Find the average change in revenue if production is changed from 1,000 car seats to 1,050 car seats.
(B) Use the four-step process to find
(C) Find the revenue and the instantaneous rate of change of revenue at a production level of 1,000 car seats, and write a brief verbal interpretation of these results
Answer:
(A) $437.5
(B) R'(x) = 60 - 0.05·x
(C) $10
Step-by-step explanation:
(A) Here we have the change in revenue when production is increased from 1,000 car seats to 1,050 car seats is given as follows;
R(1050) - R(1000) = 60×1050 - 0.025×1050² - (60×1000 - 0.025×1000²)
R(1050) - R(1000) = 63000 - 27562.5 - 35000 = $437.5
(B) R'(x) is given by
Step 1. R(x + h) = 60·(x+h) - 0.025·(x+h)²
Step 2 R(x + h) - R(x) = 60·(x+h) - 0.025·(x+h)² - 60·x - 0.025·x² = [tex]-\frac{h^2+(2x-2400)h}{40}[/tex]
Step 3
[tex]\frac{R(x+h)- R(x)}{h} = -\frac{h^2+(2x-2400)h}{40 \times h} = -\frac{h +2x - 2400}{40}[/tex]
Step 4
[tex]\lim_{h \to 0} \frac{R(x+h)- R(x)}{h} = \lim_{h \to 0} -\frac{ h +2x - 2400}{40}[/tex]
∴ R'(x) = 60 - 0.05·x
(c) The revenue at a production level of 1000 car seats is
R(1000) = (60×1000 - 0.025×1000²) = $35,000
The instantaneous rate of change of revenue is given as follows
R'(x) = 60 - 0.05·x = 60 - 0.05×1000 = $10.
A) The average change in revenue when production is changed from 1,000 car seats to 1,050 car seats is $8.75. B) The derivative of the revenue function R1(x) with respect to x is R′1(x) = 60 - 0.05x. C) At a production level of 1,000 car seats, the revenue is $35,000 and the instantaneous rate of change of revenue is $10.
Explanation:(A) To find the average change in revenue, we need to calculate the change in revenue and divide it by the change in the number of car seats produced. Let's calculate:
For 1,000 car seats, the revenue is R1(1000) = 60(1000) - 0.025(10002) = $60,000 - $25,000 = $35,000.For 1,050 car seats, the revenue is R1(1050) = 60(1050) - 0.025(1050x2) = $63,000 - $27,562.50 = $35,437.50.The change in revenue is $35,437.50 - $35,000 = $437.50.The change in the number of car seats produced is 1,050 - 1,000 = 50.The average change in revenue is $437.50/50 = $8.75.(B) To find R′1(x), we need to calculate the derivative of the revenue function R1(x) with respect to x. Let's differentiate:
R′1(x) = d/dx(60x - 0.025x2) = 60 - 0.05x
(C) At a production level of 1,000 car seats, the revenue is $35,000. The instantaneous rate of change of revenue (also known as the marginal revenue) at this production level can be found by substituting x = 1,000 into R′1(x):
R′1(1000) = 60 - 0.05(1000) = 60 - 50 = $10. The revenue at this production level is $35,000 and the instantaneous rate of change of revenue is $10, which represents the additional revenue obtained from producing one additional car seat.

Answer: therefore A= 0.1 and B=0.85
Step-by-step explanation:
The values of 'a' and 'b' in the frequency table are 0.1 and 0.1
We have,
To complete the conditional relative frequency table, we need to find the values of the letters 'a' and 'b'.
We know that the total for each row and column should add up to 1.
So, we can use this information to set up two equations and solve for the values of 'a' and 'b'.
Equation 1:
0.9 + b = 0.88
This equation represents the total percentage of students aged 16 years who finish homework before 10 pm.
We subtract 0.9 and 0.88 from both sides to get:
b = 0.88 - 0.9
b = -0.02
This means that the value of 'b' is negative, which doesn't make sense.
So, we made an error in setting up the equation.
We can check the table to find the correct value of 'b'.
We know that the total for the column "Before 10 pm" should be 1.
This means that the sum of the percentages 0.9 and 'b' should be equal to 1.
So,
Equation 2:
0.9 + b = 1
Solving for 'b', we get:
b = 1 - 0.9
b = 0.1
Now, we can use Equation 2 to solve for 'a':
0.15 + a = 0.12
Subtracting 0.15 from both sides, we get:
a = 0.12 - 0.15
a = -0.03
Again, we get a negative value for 'a', which doesn't make sense.
So, we need to check our work again.
We know that the total for the row "16 years" should be 1.
This means that the sum of the percentages 0.9 and 'a' should be equal to 1.
So,
0.9 + a = 1
Solving for 'a', we get:
a = 1 - 0.9
a = 0.1
Therefore,
The values of 'a' and 'b' in the frequency table are 0.1 and 0.1

Step 2: Divide both sides by 5.
5c

=
9d+103
5c =9/5 d+103/5
Answer:
c=8, d = -7
Step-by-step explanation:
6c - 9d = 111
5c - 9d = 103
Multiply the second equation by -1
-5c + 9d = -103
Add this to the first equation to eliminate d
6c - 9d = 111
-5c + 9d = -103
------------------------
c = 8
Now we need to find 9
6c - 9d = 111
Substitute in c=8
6(8) -9d = 111
48 - 9d = 111
Subtract 48 from each side
49-48 -9d = 111-48
-9d =63
Divide each side by -9
-9d/-9 = 63/-9
d = -7

The average goal the team must have to win the Jokie finals is more than 20 points.
The goals obtained by the team are:
X = {25, 12, 15, 23, 24, 39, 13, 31, 19, 16}
The arithmetic mean is the average value of a data set. The formula to compute the arithmetic mean is:
[tex]\bar X=\frac{1}{n}\sum X_{i}[/tex]
Compute the arithmetic mean of the goals scored by the players as follows:
[tex]\bar X=\frac{1}{n}\sum X_{i}[/tex]
[tex]=\frac{1}{10}\times (25+12+15+23+24+39+13+31+19+16)[/tex]
[tex]=\frac{1}{10}\times 217\\[/tex]
[tex]=21.7[/tex]
The arithmetic mean of the goals scored by the players is 21.7 points.
The average score is greater than 20 points.
Thus, the team qualified for the finals.

Which is the equation of a line that has a slope of 4 and passes through point (1, 6)?
Answer:
The answer to your question is y = 4x + 2
Step-by-step explanation:
Data
slope = m = 4
Point = (1, 6)
Process
1.- Write the equation of the line in the point slope form.
y - y1 = m(x - x1)
2.- Identify the values of x1 and y1
x1 = 1 y1 = 6
3.- Substitution
y - 6 = 4(x - 1)
4.- Simplification
y - 6 = 4x - 4
5.- Solve for y
y = 4x - 4 + 6
6.- Result
y = 4x + 2

Find the area of a circle with a circumference of \blueD{50.24}50.24start color #11accd, 50, point, 24, end color #11accd units.
Answer:
[tex]201 cm^2[/tex]
Step-by-step explanation:
The circumference of a circle is given by:
[tex]c=2\pi r[/tex]
where
r is the radius of the circle
For the circle in this problem,
c = 50.24 cm
Therefore the radius is:
[tex]r=\frac{c}{2\pi}=\frac{50.24}{2\pi}=8 cm[/tex]
The area of a circle is given by the formula
[tex]A=\pi r^2[/tex]
where r is the radius.
For the circle in this problem,
r = 8 cm
So the area is
[tex]A=\pi \cdot 8^2 = 201 cm^2[/tex]
The area of the circle is 201 cm square.
Calculation of the area of the circle:Since we know that
Circumference of the circle = [tex]2\pi r[/tex]
So here radius should be
[tex]= c\div 2\pi \\\\= 50.24\div 2\pi[/tex]
= 8 cm
Now the area of the circle is
[tex]= \pi r^2\\\\= 3.14\times 8^2[/tex]
= 201
Hence, we can conclude that The area of the circle is 201 cm square.

Step-by-step explanation:
antiderivative of Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antiderivative.) f(x) = 6 x 5 − 8x4 − 9x2.) f(x) = 6x5 − 8x4 − 9x2 the function.
Answer:
x^6 - (8/5)x^5 - 3x^3 + C.
Step-by-step explanation:
f(x) = 6x^5 - 8x^4 - 9x^2.
Using the general form antiderivative of Ax^m = Ax(m+1) / (m+1)+ C:
Antiderivative = 6 * x^(5+1) / 6 - 8 * x^(4+1) / 5 - 9 * x^(2+1) / 3 + C
= 6x^6/6 - 8x^5/5 - 9x^3/3 + C
= x^6 - (8/5)x^5 - 3x^3 + C.
Differentiating:
f'(x) = 6x^(6-1) - 8 x^(5-4) - 9x^(3-1) + 0
f'(x) = 6x^5 - 8x^4 - 9x^2.
The most general antiderivative of the given function f(x) = 6x5 − 8x4 − 9x2 is F(x) = x^6 - 8/5 * x^5 - 3x^3 + C, where C is the constant of the antiderivative.
Explanation:To find the most general antiderivative of the given function f(x) = 6x5 − 8x4 − 9x2, we need to perform the process of integration, which is the reverse of differentiation. The antiderivative F(x) will be found by integrating each term of the function separately.
The antiderivative of f(x) will then be:
F(x) = ∫6x5 dx - ∫8x4 dx - ∫9x2 dx,
Transitioning to the next step by applying the power rule for integration, we add 1 to the exponent and divide by the new exponent, we obtain
F(x) = 6/6 * x^(5+1) - 8/5 * x^(4+1) - 9/3 * x^(2+1) + C
Simplified, the antiderivative F(x) becomes:
F(x) = x^6 - 8/5 * x^5 - 3x^3 + C,
where C is the constant of the antiderivative.
