The number of students in the van are 6 and in the bus are 35.

A system of equations is a combination of equations with a common solution pair.

Given is that the senior class at high school A rented and filled 3 vans and 7 buses with 263 students. High school B rented 12 vans and 3 buses with 177 students. every van had the same number of students in it as did the buses.

Assume that there are {x} students in each van and {y} students in each bus. We can write the system of equations as -

3x + 7y = 263

12x + 3y = 177

Now, we can write -

3x + 7y = 263

3x = 263 - 7y

4 x 3x = 4(263 - 7y)

12x = 1052 - 28y

So -

1052 - 28y + 3y = 177

25y = 1052 - 177

25y = 875

y = 35                                           ... { 1 }

and

3x + 7 x 35 = 263

3x = 18

x = 6                                            ... { 2 }

Therefore, the number of students in the van are 6 and in the bus are 35.

The compound probability is P(R and then R) = P(R) x P(R|R) = (3/10) x (2/9) = 0.0667 or 6.67% (rounded to two decimal places)

Probability is a measure of the likelihood or chance that an event will occur. It is a mathematical concept used to quantify the degree of uncertainty of a particular outcome in a random process.

The probability of an event occurring is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur. The probability of an event occurring can also be expressed as a percentage, with 0% indicating that the event is impossible and 100% indicating that the event is certain to occur.

The calculation of probability involves determining the number of possible outcomes that satisfy the condition of interest and dividing that number by the total number of possible outcomes in the sample space.

For example, if you toss a fair coin, the probability of getting heads is 0.5 or 50%, since there are two possible outcomes (heads or tails), and each outcome is equally likely. Similarly, if you roll a fair six-sided die, the probability of getting a 4 is 1/6 or approximately 0.167, since there is only one possible outcome of rolling a 4, out of six possible outcomes.

Probability is used in various fields, such as statistics, economics, engineering, and science, to analyze data, make predictions, and make decisions based on uncertain outcomes. It is an essential concept in many areas of study, and its applications are widespread.

Let's denote the events as follows:

R = selecting a red marble

B = selecting a blue marble

W = selecting a white marble

a) The probability of selecting a blue marble on the first draw, followed by a red marble on the second draw:

The probability of selecting a blue marble on the first draw is 6/10 (since there are 6 blue marbles out of a total of 10 marbles). If a blue marble is selected on the first draw, then there are 9 marbles left in the box, including 3 red marbles. The probability of selecting a red marble on the second draw, given that a blue marble was selected on the first draw, is 3/9. Therefore, the compound probability is:

P(B and then R) = P(B) x P(R|B) = (6/10) x (3/9) = 0.2 or 20%

b) The probability of selecting a white marble on the first draw, followed by a blue marble on the second draw, followed by a red marble on the third draw:

The probability of selecting a white marble on the first draw is 1/10. If a white marble is selected on the first draw, then there are 9 marbles left in the box, including 6 blue marbles. The probability of selecting a blue marble on the second draw, given that a white marble was selected on the first draw, is 6/9. If a blue marble is selected on the second draw, then there are 8 marbles left in the box, including 3 red marbles. The probability of selecting a red marble on the third draw, given that a white marble was selected on the first draw and a blue marble was selected on the second draw, is 3/8. Therefore, the compound probability is:

P(W and then B and then R) = P(W) x P(B|W) x P(R|W and B) = (1/10) x (6/9) x (3/8) = 0.025 or 2.5%

c) The probability of selecting a red marble on the first draw, followed by another red marble on the second draw:

The probability of selecting a red marble on the first draw is 3/10. If a red marble is selected on the first draw, then there are 9 marbles left in the box, including 2 red marbles. The probability of selecting another red marble on the second draw, given that a red marble was selected on the first draw, is 2/9. Therefore, the compound probability is:

P(R and then R) = P(R) x P(R|R) = (3/10) x (2/9) = 0.0667 or 6.67% (rounded to two decimal places)

The amount after 5 years with a simple interest of 5 % is A = $ 875

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the amount in the bank after 5 years be A

Let the simple interest be represented as I

Now , the principal amount invested = $ 700

The rate of interest r = 5 %

The number of years n = 5 years

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

On simplifying , we get

Simple Interest I = ( 700 x 5 x 5 ) / 100

Simple Interest I = 25 x 7

Simple Interest I = $ 175

Now , the amount after 5 years = P + I = 700 + 175

The amount after 5 years = $ 875

Hence , the amount after 5 years in the bank is $ 875

Ashley thinks the lines are parallel is correct. Meanwhile, Alexandro is wrong, he thinks the lines are neither.

The two lines, y = -2x + 7 and 6x + 3y = 21, are parallel because they have the same slope.

To determine if two lines are parallel, we need to check if their slopes are equal.

The slope of the first line, y = -2x + 7, is -2.

The slope of the second line, 6x + 3y = 21, can be found by rearranging the equation to solve for y:

3y = -6x + 21, divided by 3

y = -2x + 7

The slope of the second line is also -2. Since the slopes are equal, the lines are parallel.

However, to determine if two lines are perpendicular, we need to check if the product of their slopes is -1. The slope of the first line is -2, and the slope of the second line is -2.

The product of their slopes is (-2)(-2) = 4, which is not equal to -1. Therefore, the lines are not perpendicular.
