Step-by-step explanation:

Answer:

the answer to this question is 107

Answer:

14

Step-by-step explanation:

Answer:

We can start by multiplying the first equation by 3:

12x + 24y = 120

Then we can multiply the second equation by 4:

12x - 8y = 56

Now, we have:

12x + 24y = 120

12x - 8y = 56

If we subtract the first equation from the second equation:

32y = 64

y = 64/24

y = 2

Now that we know the value of y, we can substitute it back into one of the original equations to find the value of x.

Let's use the first equation:

4x+8(2) = 40

4x+16 = 40

4x = 24

x = 24/4

x =6

So, the solution of the system of equations is x = 6, y = 2.

Surrender charges safeguard against such losses. Surrender costs on some annuities and insurance products can apply for as short as 30 days or as long as 15 years. If you cash in your investment in year one, the surrender cost for annuities and life insurance is typically 10%.

The surrender period is the amount of time that an investor must wait before withdrawing cash from an annuity without penalty. Surrender periods can last many years, and withdrawing funds before the conclusion of the surrender term may result in a surrender charge, which is basically a delayed sales cost.

The longer the surrender time, in general, but not always, the better the annuity's other terms.

The surrender period is the period during which an investor may withdraw funds from an annuity without incurring a surrender charge.

The surrender term can last many years, and annuitants may face large fines if they remove their invested assets before the time has finished.

Other financial instruments include a surrender period as well B-share mutual funds and entire life insurance plans are two examples.

Each tray will have 18 pieces after they have been cut to the same size.

To find the number of pieces on each tray after they have been cut to the same size, we need to find the least common multiple (LCM) of 3, 6, and 9. This will give us the smallest number of pieces that all three trays can be divided into without any remainder.

The LCM of 3, 6, and 9 is 18. This means that all three trays can be divided into 18 equal-size pieces without any remainder.

So, each tray will have 18 pieces after they have been cut to the same size. It is important to note that this is the smallest number of pieces that all three trays can be divided into, and any larger number would also work.

To calculate how much does July make per week we have to take into account the following information:

Services that July currently make every week.

To calculate the total earned by July we have to multiply the price of each service by the number of customers of each one. Additionally, we have to add all results as shown in the following.

$195 + $170 + $160 + $90 + $60 = $675

To calculate how much does July make per weekend we have to take into account the following information:

Services that July currently make every weekend.

To calculate the total earned by July we have to multiply the price of each service by the number of customers of each one. Additionally, we have to add all results as shown in the following.

2 * $85 = $170

2 * $65 = $130

3 * $95 = $285

2 * $65 = $130

$170 + $130 + $285  * $130 = $715

To calculate how much July makes on a given month we have to add the weekend earnings with week earnings and multiply it by four (taking into account that a month has four weeks).

The value of probability P(A ∩ B) = 3/10 = 0.3.

Probability is a measure of the likelihood of a particular event occurring. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain to occur.

Probability is used in many fields such as statistics, finance, economics, and science to make predictions and decisions based on uncertain information

Event A is drawing an odd card, which means that the odds are 5/10 or 1/2.

Event B is drawing a four or higher, which means that the odds are 7/10.

Event A ∩ B means that we are interested in the probability of drawing an odd card and drawing a card of four or higher at the same time. There are 3 cards that are both odd and four or higher, which are 5,7, and 9. So the probability of drawing one of these cards is 3/10.

Therefore, The value of probability P(A ∩ B) = 3/10 = 0.3.

Permutation:

In mathematics, permutation refers to the process of placing all members of a set into an order or sequence. In other words, if the set is already ordered, the permutation of its elements is called permutation. Substitutions occur in more or less noticeable ways in almost all areas of mathematics. They often occur when different orders are considered in a particular finite set.

Combination:

Combining is a way of selecting items from a collection, and (unlike permutation) the order of selection does not matter. In smaller cases you can count the number of combinations. Combining refers to combining n things, taken k times at once, without repetition.

According to the Question:

The first team can be chosen in ⁸C₂ = 28 ways.

After that, there are 6 people left, from which there are ⁶C₂ = 15 ways to choose the second team.

The second relation is a function

The three (3) true statements about the quadratic function and its graph include the following:

A. The value of f(–10) = 82

B. The graph of the function is a parabola.

D. The graph contains the point (20, –8).

Generally speaking, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped. For this quadratic function, the graph is a upward parabola because the coefficient of x² is positive and the value of "a" is greater than zero.

Next, we would determine the other true statements about the graph of this quadratic function:

At point (-10, 82), we have:

Quadratic function, f(x) = 1/5 x² – 5x + 12

Quadratic function, f(x) = x²/5 – 5x + 12

Quadratic function, f(-10) = -10²/5 – 5(-10) + 12

Quadratic function, f(-10) = 82

At point (20, -8), we have the following:

Quadratic function, f(x) = 1/5 x² – 5x + 12

Quadratic function, f(x) = x²/5 – 5x + 12

Quadratic function, f(20) = 20²/5 – 5(20) + 12

Quadratic function, f(20) = -8

In conclusion, we can logically deduce that the graph of this quadratic function does not contain the point (0, 0) as shown in the image attached below.
