Answer:

  15, 35

Step-by-step explanation:

Let x represent the smaller number. Then the larger is 3x-10, ten less than 3 times the smaller. Their total is ...

  x + (3x -10) = 50

  4x = 60 . . . . . . . . add 10

  x = 15 . . . . . . . . . .divide by 4

  50 -15 = 35

The two numbers are 15 and 35.

Step-by-step explanation:

x^2+20=4 first isolate the variable by subtracting 20 on both sides.

x^2=-16 again isolate the variable but this time you square root both sides.

Answer:

Step-by-step explanation:

This problem is a composition of function defined by C(V(r)), now we have the functions \(V(r)= \pi r^{3}\) and \(C(V)=3.2V\), where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,

\(C(V(r))=3.2(\pi r^{3} )\)

Therefore, the right answer is the last choice.

\\4&-9\end{bmatrix}\)

\( 2A=2\begin{bmatrix}3&6\\1&4\end{bmatrix}

Answer:

110

Step-by-step explanation:

nth term = 3n + 2

3 (36) + 2

108 + 2 = 110

Answer:

The 36th term in the sequence is 104.

Here's how to find it:

- Start with the first number in the sequence: 5.

- Add the common difference, which is 3, to get the second number in the sequence: 8.

- Add the common difference to the second number to get the third number: 11.

- Continue adding the common difference to each subsequent number to find the next term in the sequence.

- The 36th term is three less than 37 times the common difference added to the first term.

- Using that formula, we can calculate the 36th term as: 5 + (36 - 1) * 3 = 5 + 105 = 110.

- Therefore, the 36th term in the sequence is 104.

(a). The Tanakas paid a total of $523,906.40 for the townhome.

(b). The Tanakas paid $206,906.40 in interest on their mortgage over the 15-year period.

Simple interest is the type of interest that is calculated on the principal amount only.

It is a fixed percentage of the principal amount that is charged or earned over a certain period of time, without any compounding of interest.

(a) The total amount they ended up paying for the townhome is the sum of the down payment and the total amount of the mortgage payments.

Down payment = $41,000

Total amount of mortgage payments = monthly payment x number of payments = $2675.04 x 12 months/year x 15 years = $482,906.40

Total amount paid = down payment + total amount of mortgage payments = $41,000 + $482,906.40 = $523,906.40

(b) The amount of interest paid on the mortgage can be calculated by subtracting the principal (the amount borrowed) from the total amount paid.

Principal = Total cost of townhome - Down payment = $358,000 - $41,000 = $317,000

Total interest paid = Total amount paid - Principal = $523,906.40 - $317,000 = $206,906.40

C

Step-by-step explanation:

Answer: C

Out of 6 spaces on number line, C is the 3rd one

The production schedule for maximum profit is; X = 3 and Y = 6 with a maximum profit of $960

We are told that  two products X and Y, has a total production capacity of 9 tones per day, X and Y requiring the same production capacity

The firm has a permanent contract to supply at least 2 tones of X and at least 3 tones of Y per day to another company.

Let product A be x and product B be y. Therefore we have the following inequalities and constraints as;

x + y ≤ 9

x ≥ 2

y ≥ 3

Now, we are told that each tonne of A requires 20 machine hours of production time and each tonne of B requires 50 machine hours of production time. The daily maximum possible number of machine hours is 360. Thus, we have;

20x + 50y ≤ 360

Wea re told that all the firm's output can be sold and the profit made is $80 per tonne of A and $120 per tonne of B. Thus, we have the inequality as;

Z = 80x + 120y  maximize

The solution from the graph attached is;

x = 3, y = 6

Thus, the maximum profit is;

Z = 80(3) + 120(6)

Z = 960

Answer:

The y-intercept is the point in which the line crosses the y-axis (meaning, you'd find -2 on the y-axis).

Slope is the movement up or down and left or right, from the y-intercept (in this case we'll move downwards 3 units and to the right 2 units, and we'll keep doing this until our line forms).

I'll graph it for you, so you can get a visual, (but you really should do what the other person said and check out Desmos. It's really neat, and you don't even have to download it.)

Hope this helps you :)

The graph of the line with a slope of -3/2 and a y-intercept of -2 is a downward-sloping line passing through the point (0, -2) and (2, -5).

To graph the given features, which include the slope and y-intercept, we can use the slope-intercept form of a linear equation, which is y = mx + b.

Given:

Slope (m) = -3/2

Y-intercept (b) = -2

Using these values, we can write the equation of the line as:

y = (-3/2)x - 2

To graph this line, follow these steps:

1. Plot the y-intercept: Start at the point (0, -2) since the y-intercept is -2.

2. Use the slope to determine the next point: Since the slope is -3/2, this means that for every 2 units you move to the right, you move down 3 units.

  Start from the y-intercept point (0, -2) and move 2 units to the right, then 3 units down to plot the next point.

  This gives us the point (2, -5).

3. Connect the two points: Draw a straight line passing through the plotted points (0, -2) and (2, -5).

Answer:

\(Probability = \frac{845}{5832}\)

Step-by-step explanation:

Given

Two standard dice

Required

Probability that the outcome will be greater than 8 for the first time on the third roll

First, we need to list out the sample space of both dice

\(S_1 = \{1,2,3,4,5,6\}\)

\(S_2 = \{1,2,3,4,5,6\}\)

Next, is to list out the sample when outcome of both dice are added together\(S = \{2,3,4,5,6,7,3,4,5,6,7,8,4,5,6,7,8,9,5,6,7,8,9,10,6,7,8,9,10,11,7,8,9,10,11,12\}\)

Next, is to get the probability that an outcome will be greater than 8

Represent this with P(E)

\(P(E) = \frac{Number\ of\ outcomes\ greater\ than\ 8}{Total}\)

\(P(E) = \frac{10}{36}\)

\(P(E) = \frac{5}{18}\)

Next, is to get the probability that an outcome will noy be greater than 8

Represent this with P(E')

\(P(E) + P(E') = 1\)

\(P(E') = 1 - P(E)\)

\(P(E') = 1 - \frac{5}{18}\)

\(P(E') = \frac{18 - 5}{18}\)

\(P(E') = \frac{13}{18}\)

Now, we can calculate the required probability;

Probability of a number greater than 8 first on the third attempt is:

Probability of outcome not greater than 8 on the first attempt * Probability of outcome not greater than 8 on the second attempt * Probability of outcome greater than 8 on the third attempt

Mathematically;

\(Probability = P(E') * P(E') * P(E)\)

Substitute values for P(E) and P(E')

\(Probability = \frac{13}{18} * \frac{13}{18} * \frac{5}{18}\)

\(Probability = \frac{13 * 13 * 5}{18 * 18 * 18}\)

\(Probability = \frac{845}{5832}\)

The mathematical model that represents the general price movement of mortgages is:     ΔPM = f(Δk, ΔPrin, ΔC)

Where ΔPM is the change in the price of the mortgage, Δk is the change in the required rate of return, ΔPrin is the change in the principal payment, and ΔC is the change in the interest payment.

This means that the change in the price of a mortgage is a function of the change in the required rate of return, the change in the principal payment, and the change in the interest payment.

The securities that are issued to financial institutions to increase liquidity in the secondary mortgage market by financing the origination of mortgages are:

Financial institutions may also receive private-label pass-through securities, although these are not guaranteed by government entities like Ginnie Mae, Freddie Mac, or Fannie Mae.

They are not backed by the government, but by private institutions, which can make them riskier.

x=10 and x=-4

Step-by-step explanation:

When the absolute value is all by itself on one side of the equation, the next step is to remove the absolute value bars. This will create TWO separate equations.

Here is the second equation:

x - 3 = -7

It is the left side copied, without the bars, but the right side has the opposite sign.

The mean ; m

Mean, m = Σx /n

Σx = 377.7

n = sample size = 13

m = Σx / n = 377.7 / 13 = 29.05

Median = 1/2(n+1)th term

= 1/2(14) = 7th term = 29.5

Range = maximum - minimum

Range = 34.5 - 17.5 = 17

Lower quartile (Q1) = 1/4(n+1)th term

1/4(14)th term = 3.5th term

(3rd + 4th) / 2

= (27.4 + 28.6) / 2

= 28

Upper quartile (Q3) = 3/4(n+1)th term

3/4(14)th term = 10.5th term

(10th + 11th) / 2

= (31.7 + 32.3) / 2
