Answer:

\(1,814,400\)

Step-by-step explanation:

The number of ways to arrange a word with \(d\) distinct digits is each to \(d!\). Since there are 10 letters, there are \(10!\) permutations initially formed.

However, there is one letter that is repeated, S. We need to account for that fact that switching the placement of the S's does not change the word, as they still appear the same. Therefore, divide \(10!\) by the number of ways you can arrange the 2 S's, which is simply \(2!\). Therefore, our answer is:

\(\frac{10!}{2!}=10 \cdot 9\cdot 8\cdot 7\cdot 6\cdot 5\cdot 4\cdot 3=\boxed{1,814,000}\)

Answer:

360 mi^3

Step-by-step explanation:

The figure is composed by two parallelepipeds. For find the volume we have to find the volume of both the solids and the added up the two values

solid  1

length = 11 - 4 = 7 mi

base area = length x width = 7 x 4 = 28 mi^2

V = base area x height = 28 x 6 = 168 mi^3

solid 2

base area = 8 x 4 = 32 mi^2

V = 32 x 6 = 192 mi^3

total volume: 168 + 192 = 360 mi^3

The volume of the figure is 360 mi³.

Volume of a three dimensional shape is the space occupied by the shape.

Given is a figure where two rectangular boxes are put on top of each other.

Volume of a rectangular prism = L × W × H

Here L is the length, W is the width and H is the height.

The dimensions of the rectangular prism are :

Larger one having L = 11 mi, W = 6 mi and H = 4 mi

Smaller one on top having L = 4 mi, W = 6 mi and H = 8 - 4 = 4 mi.

Volume of the figure = volume of larger box + Volume of smaller box

                                  = (11 × 6 × 4) + (4 × 6 × 4)

                                  = 264 + 96

                                  = 360 mi³

Hence the volume of the figure is 360 mi³.

Using proportions, it is found that the correct option for when the machine will stop running the algorithm is:

B) 9 P.M. on Saturday.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The algorithm runs for 972 hours. Each day has 24 hours, hence we apply the proportion to find the number of days as follows:

972/24 = 40.5 days.

The remainder of the division of 40.5 by 7, as a week has 7 days, is of 5.5, which means that the code will finish running 5.5 days after the 9 A. M. Monday, that is at 9 P. M. on a Saturday, which means that option B is correct.

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.

Answer:

The answer is not complete. I will explain the concept of profit to you.

Step-by-step explanation:

We can determine profit deducting direct costs (cost price) of commodities from sales (selling prices) of the commodities.

Profit = Selling Price - Cost Price

Example:

A trader buys some dresses for #2,500 in May and agrees to pay for it in three months’ time. He sells off all the dresses in August for #4,500. The profit for the month is #2,000.

The formula for percentage profit is \(\frac{profit * 100}{cost price}\)

The formula for gross profit is Revenue – Cost of Sold Items

Profit Margin =  \(\frac{Total Income}{Net Sales}\) * 100

While Gross Profit Margin can be calculated as \(\frac{Gross Profit}{Net Sales}\) * 100

Any of these formulas can be used to calculate profit-related questions.

Step-by-step explanation:

Answer: J (The cakes that Jake has) +5 = H (the cakes that Harold has), or J + 5 = H

Step-by-step explanation:

Harold has 5 more cakes than Jake.

To write this as an expression, we must make a variable for Harold and Jake's cakes.

Let's put H and J respectively for the two.

Now, we must show that Harold, or H, has 5 more cakes than Jake.

We can show that by putting +5 next to Jake's variable.

This shows that Harold has 5 more cakes than Jake.

Now, we know that Jake's cakes plus 5 equal Harold's cakes, so we can easily write the expression as J+5=H.

To calculate the total number of possible outcomes we need to multiply the number of options for each component (die, first spinner, second spinner).

For the first component we have 4 options, for the second component-  3 options and for the third component- 5 options.

Therefore, the total number of possible outcomes is:

a. 20.31% of New York's high school teachers earn between 83,000 and 88,000

b.  18.49% of New York teachers earn between 88,000 and 103,000

c. 1.19%  of New York’s state high school teachers earn less than 73,000

Given,

The salary for high school teachers in 2017 = 97010

Standard deviation = 9540

Consider salaries as normal distribution.

Here,

Mean, μ = 97010, Standard deviation, σ = 9540

a. Percentage of New York's high school teachers earn between 83,000 and 88,000

The proportion is the p-value of Z when X = 88,000 subtracted by the p-value of Z when X = 83,000.

That is,

X = 88,000

Z = (X - μ) / σ = (88,000 - 97010) / 9540 = -9010/9540 = -0.944

The p value of z score - 0.944 is 0.3452

Next,

X = 83,000

Z = (X - μ) / σ = (83,000 - 97010) / 9540 = -14010/9540 = -1.468

The p value of z score - 1.468 is 0.1421

Then,

0.3452 - 0.1421 = 0.2031 = 20.31%

That is,

20.31% of New York's high school teachers earn between 83,000 and 88,000

b. Percentage of New York teachers earn between 88,000 and 103,000

The proportion is the p-value of Z when X = 103,000 subtracted by the p-value of Z when X = 88,000

X = 103,000

Z = (X - μ) / σ = (103,000 - 97010) / 9540 = 5990/9540 = 0.6279

The p value of z score 0.6279 is 0.5301

Next,

X = 88,000

Z = (X - μ) / σ = (88,000 - 97010) / 9540 = -9010/9540 = -0.944

The p value of z score - 0.944 is 0.3452

Then,

0.5301 - 0.3452 = 0.1849 = 18.49%

That is,

18.49% of New York teachers earn between 88,000 and 103,000

c.  Percentage of new York’s state high school teachers earn less than 73,000

The proportion is the p-value of Z when X = 73000

X = 73,000

Z = (X - μ) / σ = (73,000 - 97010) / 9540 = -24010/9540 = -2.516

The p value of z score - 2.516 is 0.0119

Answer:

15595 bacteria will be present after 13 hours.

Step-by-step explanation:

Continuous population growth:

The continuous population growth model, for the population after t hours, is given by:

\(P(t) = P(0)e^{rt}\)

In which P(0) is the initial population and r is the growth rate.

Started with 5000 bacteria

This means that \(P(0) = 5000\)

So

\(P(t) = 5000e^{rt}\)

After three hours it grew 6500 bacteria:

This means that \(P(3) = 6500\). We use this to find r.

\(P(t) = 5000e^{rt}\)

\(6500 = 5000e^{3r}\)

\(e^{3r} = \frac{65}{50}\)

\(\ln{e^{3r}} = \ln{\frac{65}{50}}\)

\(3r = \ln{\frac{65}{50}}\)

\(r = \frac{\ln{\frac{65}{50}}}{3}\)

\(r = 0.0875\)

So

\(P(t) = 5000e^{0.0875t}\)

How many bacteria will be present after 13 hours?

This is P(13). So

\(P(13) = 5000e^{0.0875*13} = 15594.8\)

Rounding to the nearest whole number

15595 bacteria will be present after 13 hours.

Answer:

Variable selling costs per unit. $ 5. Allocated fixed selling costs per unit ... P + FC = Q x (SP – VC).

Step-by-step explanation:

Variable selling costs per unit. $ 5. Allocated fixed selling costs per unit ... P + FC = Q x (SP – VC).

$1356.52 is the cost price of the article.

To find the cost price of the article, we can utilize the concept of calculating the original amount based on a percentage increase.

Let's assume the cost price of the article is "x" dollars.

The trader gained a 15% interest, which means the selling price is 115% of the cost price. In other words, the selling price is 115% of "x".

To calculate the selling price, we can set up the following equation:

115% of x = 1560

To convert the percentage to a decimal, we divide it by 100:

1.15 * x = 1560

Now we can solve for x by dividing both sides of the equation by 1.15:

x = 1560 / 1.15

Using a calculator, we find:

x ≈ 1356.52

Therefore, the approximate cost price of the article is $1356.52.

This means that the trader purchased the article for around $1356.52 and then sold it for $1560.00, resulting in a 15% gain.
