what expression is equivalent to 3(6m)+m

Answer:

C) 1/2

Step-by-step explanation:

We know that 3/8 cup of brown sugar and 1/3 cup of white sugar are mixed together to make the sugar mixture.

From this sugar mixture, 1/4 cup is set aside for the crumb topping.

To find out how much sugar mixture is used to make the cake, we need to subtract the amount set aside for the crumb topping from the total sugar mixture.

We can start by converting the mixed unit of measurement (brown sugar in cups and white sugar in cups) to a single unit of measurement (cups)

3/8 cup of brown sugar + 1/3 cup of white sugar = (3/8)+(1/3) = 5/12 cup + 4/12 cup = 9/12 cup.

1/4 cup is set aside for the crumb topping.

So, the remaining sugar mixture used to make the cake is 9/12 cup - 1/4 cup = (9/12) - (1/4) = (9-3)/12 = 6/12 cup = 0.5 cup

There is about a 33.7% probability that a case of 48 cans will contain at least two cans with a defective ball.

To solve this problem, we can use the binomial distribution. Let's define "success" as getting a can with no defective ball and "failure" as getting a can with at least one defective ball.

The probability of success in one can is:

P(success) = 1 - P(failure) = 1 - 0.025 = 0.975

The probability of failure in one can is:

P(failure) = 0.025

Now, let's define X as the number of cans in a case of 48 that have at least one defective ball. We want to find the probability that X is greater than or equal to 2.

We can use the binomial distribution formula to calculate this probability:

P(X ≥ 2) = 1 - P(X < 2) = 1 - P(X = 0) - P(X = 1)

P(X = 0) = (0.975)^48 ≈ 0.223

P(X = 1) = 48C1 (0.975)^47 (0.025)^1 ≈ 0.44

where 48C1 is the number of ways to choose one can out of 48.

Therefore, the probability that a case of 48 cans will contain at least two cans with a defective ball is:

P(X ≥ 2) ≈ 1 - 0.223 - 0.44 ≈ 0.337

The cumulative n(10) plot is useful for determining the average bombardment intensity of the surface over time.

The main difference between an r-plot and a cumulative n(10) plot is that an r-plot is a graph of the number of craters per unit area (R) versus the crater size (D), while a cumulative n(10) plot is a graph of the total number of craters larger than a certain size (N) versus the crater size (D). The r-plot is a direct representation of the cratering of a surface, as it shows the number of craters of each size present on the surface. The cumulative n(10) plot, however, shows the cumulative number of craters larger than a certain size. This is calculated by summing the number of craters greater than a certain size over the surface area (A): N(D) = ∑R(D)A. The cumulative n(10) plot is useful for determining the average bombardment intensity of the surface over time.

Step-by-step explanation:

The amount of sugar that went into each pitcher was 0.375, which was taken from the 3(3/4) cups of sugar utilized for the lemonade stand.

Division allows us to divide a large number of objects into equal-sized groups. Division is represented by the symbol ÷.

We can use the distributive property to divide larger numbers by breaking them down into smaller factors.

It is implied that Lucy made her lemonade stand using 3 3/4 cups of sugar.

Further, she distributed the sugar into 6 pitchers in equal portions.

Therefore, we need to divide the total cups of sugar by 6 to get the value of sugar that went into each pitcher.

sugar went into each pitcher = 3(3/4) ÷ 6

                                                 = (9/4) ÷ 6

                                                 = 2.25 ÷ 6

                                                 = 0.375

Therefore, each pitcher of sugar contained 0.375 of the 3(3/4) cups of sugar utilized for the lemonade stand.

Answer:

The explicit formula is Tn = 18[(2/3)^(n-1)]

Where n is the term we are looking for

Step-by-step explanation:

Here, we want to get an explicit formula to model the equation

Now, F(2) = 2/3 * f1 = 2/3 * 18 = 12

F(3) = 2/3 * f(2) = 2/3 * 12 = 8

F(4) = 2/3 * F(3) = 2/3 * 8 = 16/3

F(5) = 2/3 * 16/3 = 32/9

Thus, seeing how the equations are progressing, we can definitely see a pattern.

The proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

We have,

A normal distribution located between z = 0.50 and z = -0.50,

So,

Now,

From the Z-score table,

We get,

The Probability corresponding to the Z score of -0.50,

i.e.

P(-0.50 < X < 0) = 0.191,

And,

The Probability corresponding to the Z score of -0.50,

i.e.

P(0 < X < 0.50) = 0.191,

Now,

The proportion of a normal distribution,

i.e.

P(Z₁ < X < Z₂) = P(Z₁ < X < 0) + P(0 < X < Z₂)

Now,

Putting values,

i.e.

P(-0.50 < X < 0.50) = P(-0.50 < X < 0) + P(0 < X < 0.50)

Now,

Again putting values,

We get,

P(-0.50 < X < 0.50) = 0.191 + 0.191

On solving we get,

P(-0.50 < X < 0.50) = 0.382

So,

We can write as,

P(-0.50 < X < 0.50) = 38.2%

So,

The proportion of a normal distribution is 38.2%.

Hence we can say that the proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

The percentage increase per year in the winner's check over the given period. If the winner's prize increases at the same rate, it will be $1,454,735,139.69 in 2040.

To calculate the percentage increase per year in the winner's check over the period from 1895 to 2007, we can use the following formula:

Percentage Increase = (Final Value - Initial Value) / Initial Value * 100

a. Calculating the percentage increase:

Initial Value = $140

Final Value = $1,171,000

Percentage Increase = (1,171,000 - 140) / 140 * 100 ≈ 835,714.29%

b. To estimate the winner's prize in 2040, we can assume the same annual percentage increase will continue. We need to calculate the number of years from 2007 to 2040 and apply the percentage increase to the 2007 prize.

Number of years = 2040 - 2007 = 33 years

Estimated prize in 2040 = 1,171,000 * (1 + (Percentage Increase / 100))^33

Estimated prize in 2040 = 1,171,000 * (1 + (835,714.29 / 100))^33 ≈ $1,454,735,139.69

Therefore, if the winner's prize increases at the same rate, it is estimated to be approximately $1,454,735,139.69 in 2040.

we know that the sample size is 50, the sample mean is 30, and the sample standard deviation is 12. To construct a 95% confidence interval for the population mean, we need to use the formula: CI = X ± t* (s/√n).

where:
- X is the sample mean
- t* is the critical t-value from the t-distribution with (n-1) degrees of freedom and a confidence level of 95%
- s is the sample standard deviation
- n is the sample size.

First, we need to find the critical t-value. Since we have a sample size of 50, our degrees of freedom are (50-1) = 49. Using a t-table or calculator, we can find that the critical t-value for a 95% confidence interval with 49 degrees of freedom is 2.009.

Now we can plug in the values we have: CI = 30 ± 2.009 * (12/√50), Simplifying this expression, we get: CI = 30 ± 4.27
So the 95% confidence interval for the population mean is (25.73, 34.27).


We also need the critical value (z) for a 95% confidence interval, which is 1.96.To calculate the margin of error (ME), use the following formula: ME = z * (s / √n), ME = 1.96 * (12 / √50) ≈ 3.32

Now, construct the confidence interval by adding and subtracting the margin of error from the sample mean:
Lower limit = X - ME = 30 - 3.32 ≈ 26.68
Upper limit = X + ME = 30 + 3.32 ≈ 33.32, So, the 95% confidence interval for the population mean is approximately (26.68, 33.32).

For the matrix the true statement is given by option d. Both A and B are false.

Let's analyze each statement of the matrix as follow,

A) If A is a 3 times 5 matrix and T is a transformation defined by T(x) = Ax, then the domain of T is R⁵.

This statement is false.

The domain of the transformation T is not R⁵.

The domain of T is determined by the dimensionality of the vectors x that can be input into the transformation.

Here, the matrix A is a 3 times 5 matrix, which means the transformation T(x) = Ax can only accept vectors x that have 5 elements.

Therefore, the domain of T is R⁵, but rather a subspace of R⁵.

B) If A is a 3 times 2 matrix, then the transformation x right arrow Ax cannot be onto.

This statement is also false.

The transformation x → Ax can still be onto (surjective) even if A is a 3 times 2 matrix.

The surjectivity of a transformation depends on the rank of the matrix A and the dimensionality of the vector space it maps to.

It is possible for a 3 times 2 matrix to have a rank of 2,

and if the codomain is a vector space of dimension 3 or higher, then the transformation can be onto.

1. An event that is likely to happen, but not certain, for the number Kenisha calls is that it is a prime number. While there are several prime numbers between 1 and 75, it is not guaranteed that the number she calls will be prime. However, given the range of numbers, the probability of calling a prime number is relatively high.

2. An event that is unlikely to happen, but not impossible, for the number Kenisha calls is that it is a perfect square. Perfect squares are numbers that can be expressed as the square of an integer. In the range of 1 to 75, there are only a few perfect squares, so the chances of calling one as the bingo number are relatively low, but not impossible.

3. An event that is certain to happen for the number Kenisha calls is that it will be an integer. Since the game is played with whole numbers from 1 to 75, the number called will always be an integer, as it represents a specific whole number in the given range.

The solution is given below.

1. An event that is likely to happen, but not certain, for the number Kenisha calls is that it will be an odd number. Since there are 75 numbers in total and half of them are odd, there is a higher probability that the number called will be odd.

2. An event that is unlikely to happen, but not impossible, for the number Kenisha calls is that it will be a perfect square. There are only a few perfect square numbers between 1 and 75, so the chances of calling a perfect square number are lower compared to other numbers.

3. An event that is certain to happen for the number Kenisha calls is that it will be a number between 1 and 75. Since the numbers in the game range from 1 to 75, any number called by Kenisha will definitely fall within this range.

The correct answer for the Estimate at Completion (EAC) based on the given information is not among the provided options. The calculated EAC = $319,772.19.

Given the following information calculate the EAC and select from the list below. The project is planned for 12 months PV $30000 EV $26000 AC$29000 BAC $252000.The correct answer is option A) $293,023.25.

What is EAC? EAC (Estimate at Completion) refers to the total expected cost of the project. EAC includes the actual cost incurred to date as well as the expected cost required to complete the remaining project work.

The formula for EAC is as follows:

EAC = AC + (BAC - EV) / (CPI * SPI)

EAC= Estimated Cost at Completion, BAC= Budget at Completion, AC= Actual Cost, CPI= Cost Performance Index, SPI= Schedule Performance Index, EV= Earned Value, and PV= Planned Value.

Given, PV (Planned Value) = $30000EV, (Earned Value) = $26000, AC (Actual Cost) = $29000, BAC (Budget at Completion) = $252000.

Now, calculate CPI and SPI.

CPI (Cost Performance Index) = EV / AC = 26000 / 29000 = 0.8965SPI

(Schedule Performance Index) = EV / PV = 26000 / 30000 = 0.8667

Calculate EAC using the following formula:

EAC = AC + [(BAC - EV) / (CPI * SPI)]EAC = 29000 + [(252000 - 26000) / (0.8965 * 0.8667)]

EAC = 29000 + [226000 / 0.7773]

EAC = 29000 + 290772.19

EAC = $319,772.19

A permutation is a count of the different arrangements which can be made from a given set of things. In permutation the details matter, as the order or sequence is important. Permutation and combination are the methods employed in counting how many outcomes are possible in various situations. Permutations are understood as arrangements and combinations are understood as selections. As per the fundamental principle of counting, there are the sum rules and the product rules to employ counting easily.

According to this, if one event can occur in a ways and a second event can occur in b ways, the second event occurring after the first event did, then the two events can occur in a × b ways.

There are 26 letters in an English language.The license plate has 3 digits.  There are 10 digits from 0 to 10. The license plate has 4 digits.

The number of different license plate numbers that can be formed:

26 x 26 x 26 x 10 x 10 x 10 x 10 = 175,760,000

1.  AD would increase by $200 million due to the multiplier effects.

2. The government should increase spending by $20 million to achieve an AD increase of $100 million.

3. Bank E can lend out a maximum of $9,000.

1. To calculate the increase in aggregate demand (AD) due to multiplier effects when the government reduces taxes by $50 million and the marginal propensity to consume (MPC) is 0.75, we can use the formula:

Multiplier = 1 / (1 - MPC)

AD increase = Multiplier * Tax cut

Given that the tax cut is $50 million and MPC is 0.75:

Multiplier = 1 / (1 - 0.75) = 1 / 0.25 = 4

AD increase = 4 * $50 million = $200 million

Therefore, AD would increase by $200 million due to the multiplier effects.

2. To determine the amount the government should increase spending to increase AD by $100 million, given an MPC of 0.8, we can use a similar approach:

Multiplier = 1 / (1 - MPC)

Government spending increase = AD increase / Multiplier

Given that the desired AD increase is $100 million and MPC is 0.8:

Multiplier = 1 / (1 - 0.8) = 1 / 0.2 = 5

Government spending increase = $100 million / 5 = $20 million

Therefore, the government should increase spending by $20 million to achieve an AD increase of $100 million.

3. To calculate the maximum amount of money that Bank E can lend out, given that it has $10,000 of deposits as a liability and $1,500 in reserves, with a required reserve ratio (rr) of 10%, we can use the formula:

Maximum loan amount = Total deposits - Required reserves

Given that the required reserve ratio is 10%, which means the bank needs to hold 10% of the deposits as reserves:

Required reserves = 10% * $10,000 = $1,000

Maximum loan amount = $10,000 - $1,000 = $9,000

Therefore, Bank E can lend out a maximum of $9,000.
