The average amount of a beverage in randomly selected 16-ounce beverage can is 16.18 ounces with a standard deviation of 0.4 ounces. If a random sample of sixty-five 16-ounce beverage cans are selected, what is the probability that the mean of this sample is less than 16.1 ounces of beverage? Answer: (round to 4 decimal places)
Answer:
The probability that the mean of this sample is less than 16.1 ounces of beverage is 0.0537.
Step-by-step explanation:
We are given that the average amount of a beverage in randomly selected 16-ounce beverage can is 16.18 ounces with a standard deviation of 0.4 ounces.
A random sample of sixty-five 16-ounce beverage cans are selected
Let [tex]\bar X[/tex] = sample mean amount of a beverage
The z-score probability distribution for the sample mean is given by;
Z = [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = population mean amount of a beverage = 16.18 ounces
[tex]\sigma[/tex] = standard deviation = 0.4 ounces
n = sample of 16-ounce beverage cans = 65
Now, the probability that the mean of this sample is less than 16.1 ounces of beverage is given by = P([tex]\bar X[/tex] < 16.1 ounces)
P([tex]\bar X[/tex] < 16.1 ounces) = P( [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\frac{16.1-16.18}{\frac{0.4}{\sqrt{65} } }[/tex] ) = P(Z < -1.61) = 1 - P(Z [tex]\leq[/tex] 1.61)
= 1 - 0.9463 = 0.0537
The above probability is calculated by looking at the value of x = 1.61 in the z table which has an area of 0.9591.
What’s the correct answer for this question?
Answer:
0.37
Step-by-step explanation:
As shown in table,
The probability of the fruit is orange is P(A) = 0.3
The probability of the fruit is organic is P(B)
The probability of the fruit is orange and organic is P(A⋂B) = 0.11
=> The probability that a randomly selected orange is organic is calculated by applying the conditional probability formula:
P(B|A) =P(A⋂B)/P(A) = 0.11/0.3 = 0.37
=> Option D is correct

Emma and Max want to buy a house together.
Emma earns £18,500 and Max earns £22,500. They have £6000 savings.
They want to buy a house that is being sold for £130,000.
They will pay the deposit with their savings and take out a mortgage to pay for the rest.
Emma and Max can borrow 3 times their combined incomes as a mortgage.
They will need to pay 5% of the selling price of the value as a deposit.
How much can they borrow as a mortgage?
Answer:
£123,000
Step-by-step explanation:
Their combined income is ...
£18,500 +22,500 = £41,000
They can borrow 3 times this amount, or ...
3 × £41,000 = £123,000
__
Comment on this transaction
The required deposit is 5% of 130,000 = 6,500, which is more than their savings. After this down payment is made, the remaining value is £123,500, which exceeds their borrowing power. It appears that Emma and Max need to find a house with a lower price.
The owner of Limp Pines Resort wanted to know the average age of its clients. A random sample of 25 tourists is taken. It shows a mean age of 46 years with a standard deviation of 5 years. The width of a 95 percent CI for the true mean client age is approximately: _________
Given Information:
Sample size = n = 25
Mean age of client = 46 years
Standard deviation of age of client = 5 years
Confidence level = 95%
Required Information:
Width of the confidence interval = ?
Answer:
[tex]$ \text {width of CI } = \pm 2.064 $\\\\[/tex]
Step-by-step explanation:
The width for the true mean client age is given by
[tex]$ \text {width of CI } =\pm t_{\alpha/2}(\frac{s}{\sqrt{n} } ) $[/tex]
Where n is the sample size, s is the standard deviation of age of client, and [tex]t_{\alpha/2}[/tex] is the t-score corresponding to 95% confidence level.
The t-score corresponding to 95% confidence level is
Significance level = 1 - 0.95 = 0.05/2 = 0.025
Degree of freedom = n - 1 = 25 - 1 = 24
From the t-table at α = 0.025 and DF = 24
t-score = 2.064
[tex]$ \text {width of CI } = \pm (2.064)(\frac{5}{\sqrt{25} } ) $\\\\[/tex]
[tex]$ \text {width of CI } =\pm (2.064)(\frac{5}{5 } ) $\\\\[/tex]
[tex]$ \text {width of CI } = \pm (2.064)(1) $\\\\[/tex]
[tex]$ \text {width of CI } = \pm 2.064 $\\\\[/tex]
Therefore, width of the 95% confidence Interval for the true mean client age is approximately ±2.064.
Bonus:
The corresponding 95% confidence interval is given by
[tex]$ \text {Confidence Interval } = \bar{x} \pm t_{\alpha/2}(\frac{s}{\sqrt{n} } ) $[/tex]
Where x_bar is the mean client age
[tex]$ \text {Confidence Interval } = 46 \pm 2.064 $[/tex]
[tex]$ \text {Confidence Interval } = (43.936, 48.064) $[/tex]
[tex]$ \text {Confidence Interval } = (44, 48) $[/tex]
Which means that we are 95% sure that the true mean client age is within the range of (44, 48) years.

(1 point) Let P(t) be the performance level of someone learning a skill as a function of the training time t. The derivative dPdt represents the rate at which performance improves. If M is the maximum level of performance of which the learner is capable, then a model for learning is given by the differential equation dPdt=k(M−P(t)) where k is a positive constant. a) First solve this differential equation for P(t) using C as your final (simplified) constant parameter introduced by integrating.
Answer:
[tex]P(t)=M+Ce^{-kt}[/tex]
Step-by-step explanation:
Given the differential model
[tex]\dfrac{dP}{dt}=k[M-P(t)][/tex]
We are required to solve the equation for P(t).
[tex]\dfrac{dP}{dt}=kM-kP(t)\\$Add kP(t) to both sides\\\dfrac{dP}{dt}+kP(t)=kM\\$Taking the integrating factor\\e^{\int k dt} =e^{kt}\\$Multiply all through by the integrating factor\\\dfrac{dP}{dt}e^{kt}+kP(t)e^{kt}=kMe^{kt}\\\dfrac{dP}{dt}e^{kt}=kMe^{kt}\\(Pe^{kt})'=kMe^{kt} dt\\$Take the integral of both sides with respect to t\\\int (Pe^{kt})'=\int kMe^{kt} dt\\Pe^{kt}=kM \int e^{kt} dt\\Pe^{kt}=\dfrac{kM}{k} e^{kt} + C_0, C_0$ a constant of integration[/tex]
[tex]Pe^{kt}=Me^{kt} + C\\$Divide both side by e^{kt}\\P(t)=M+Ce^{-kt}\\P(t)=M+Ce^{-kt}\\$Therefore:\\P(t)=M+Ce^{-kt}[/tex]

Answer:
a) y=4x-3
Step-by-step explanation:
Find the slope by comparing the values within one column. If you subtract 1 from -3, you'll get the value of 4. You then notice that each time, the value increases by 4. Since the y= column is increasing by one, the value therefore remains constant because 4 divided by 1 is always 4.
Now, to find the coefficient, just look at where the y value is 0. Whatever number x is when the value is 0, that will be your coefficient because it is the y-intercept (the initial starting value); in this case -3
Answer:
A
Step-by-step explanation:
First, calculate the slope by doing rise over run.
We can do this between the first 2 points:
[tex]\frac{4}{1}[/tex] = 4
The slope is positive 4, and the y-intercept is (0, -3)
The equation is A, y = 4x - 3

) Tara earns twice as much per hour as Kayte.
Kayte earns $3 more per hour than Austin. As
a group, they earn $41 per hour. What is
Austin's hourly wage?
Answer:
Austin's hourly wage is $8.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
Tara's hourly wage is x.
Kayte's hourly wage is y.
Austin's hourly wage is z.
Tara earns twice as much per hour as Kayte.
This means that [tex]x = 2y[/tex]
Kayte earns $3 more per hour than Austin.
This means that [tex]y = z + 3[/tex]
As a group, they earn $41 per hour.
This means that [tex]x + y + z = 41[/tex]
What is Austin's hourly wage?
This is z.
[tex]x + y + z = 41[/tex]
[tex]y = z + 3[/tex] and [tex]x = 2y[/tex], so [tex]x = 2(z + 3) = 2z + 6[/tex]
[tex]x + y + z = 41[/tex]
[tex]2z + 6 + z + 3 + z = 41[/tex]
[tex]4z + 9 = 41[/tex]
[tex]4z = 32[/tex]
[tex]z = \frac{32}{4}[/tex]
[tex]z = 8[/tex]
Austin's hourly wage is $8.
Answer:
Austin's hourly wage is $8.
Step-by-step explanation:
We can write this problem as a system of linear equations.
We define T: Tara's hourly wage, A: Austin's hourly wage and K: Kayte's hourly wage.
Then, if Tara earns twice as much per hour as Kayte, we have:
[tex]T=2K[/tex]
If Kayte earns $3 more per hour than Austin, we have:
[tex]K=A+3[/tex]
And if they earn $41 per hour as a group, we know:
[tex]T+K+A=41[/tex]
We can use all equations to replace in the third one, as:
[tex]T+K+A=41\\\\(2K)+K+A=41\\\\3K+A=41\\\\3(A+3)+A=41\\\\3A+9+A=41\\\\4A=41-9=32\\\\A=32/4=8[/tex]
Austin's hourly wage is $8.

What is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.
Step by step answer
Answer:
[tex]\ S=\sqrt{\dfrac{3V}{H}}}[/tex]
Step-by-step explanation:
The opposite operation of squaring is taking the square root.
[tex]\ S=\sqrt{\dfrac{3V}{H}}}[/tex]
We know that the denominator of a fractional power is the index of the corresponding root:
[tex]\displaystyle x^\frac{1}{n}=\sqrt[n]{x}[/tex]
For n=2, we don't usually write the index in the root symbol:
[tex]x^{\frac{1}{2}}=\sqrt{x}[/tex]
In the case of this problem, ...
[tex](S^2)^{\frac{1}{2}}=\left(\dfrac{3V}{H}\right)^{\frac{1}{2}}\\\\S=\sqrt{\dfrac{3V}{H}}[/tex]

Some people say Mauna Kea is a taller mountain than Mt. Everest, because its total under sea and above sea level height is
a0 meters.
Answer:
Mauna Kea has from the base that is to say the deepest 10 km of height that is to say 10,000 m which is equivalent to being higher than Mount Everest.jj
Step-by-step explanation:
The main reason why we could say that Mauna Kea is the highest mountain, even surpassing Mount Everest, is because of its altitude if we compare them we see the difference; for example Mauna Kea from its base that is to say from the deepest the ocean measures 10,000 m of altitude, on the other hand the Mount Everest has an altitude of 8848 meters (29,029 ft) above sea level, that is to say from its base it measures 8848 m altitude.

Answer:
(a)[tex]E \cap F ={(2, 6),(4, 6),(6, 2),(6, 4),(6, 6)}[/tex]
(b) [tex]E^c \cap G =\{ \}[/tex]
Step-by-step explanation:
The sample space of two dice rolled is given below:
[tex]\{(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)\\(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)\\(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)\\(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)\\(5, 1), (5, 2), (5, 3), (5, 4), (5, 5),(5,6)\\(6, 1), (6, 2), (6, 3), (6, 4), (6,5), (6,6)\}[/tex]
For Event E (The sum is even), the outcomes are:
[tex](1, 1), (1, 3), (1, 5),(2, 2), (2, 4), (2, 6)\\(3, 1), (3, 3), (3, 5), (4, 2), (4, 4), (4, 6)\\(5, 1),(5, 3), (5, 5), (6, 2), (6, 4), (6,6)[/tex]
For Event F (Rolling at least one six), the outcomes are:
[tex](1, 6), (2, 6), (3, 6), (4, 6),(5,6),(6, 1), (6, 2), (6, 3), (6, 4), (6,5), (6,6)[/tex]
For Event G (The sum is eight), the outcomes are:
[tex](2, 6), (3, 5),(4, 4), (5, 3),(6, 2)[/tex]
(a)[tex]E \cap F[/tex]
Therefore:
[tex]E \cap F ={(2, 6),(4, 6),(6, 2),(6, 4),(6, 6)}[/tex]
(b)[tex]E^c \cap G[/tex]
E is the event that the sum is even
Therefore: [tex]E^c$ is the event that the sum is odd.[/tex]
Since G is the event that the sum is eight( which is even), the intersection of the complement of E and G will be empty.
Therefore:
[tex]E^c \cap G =\{ \}[/tex]

Consider the sets A and B
(A − (A ∩ B)) ∩ (B − (A ∩ B))
= (A ∩ (A ∩ B)c) ∩ (B ∩ (A ∩ B)c) by the set difference law
= (A ∩ (Ac ∩ B)c) ∩ (B ∩ (Ac ∩ B)c) by De Morgan's law
= {(A ∩ Ac) ∪ (A ∩ Bc)} ∩ {(B ∩ Ac) ∪ (B ∩ Bc)} by the distributive law
= {∅ ∪ (A ∩ Bc)} ∩ {(B ∩ Ac) ∪ ∅} by complementation
= {A ∩ Bc} ∩ {B ∩ Ac} by identity law
= (A ∩ Ac) ∩ (B ∩ Ac) by the associative law
= ∅ ∩ ∅ by complementation
= ∅ by the universal bound law
Therefore, (A − (A ∩ B)) ∩ (B − (A ∩ B)) = ∅
