What is the probability that a student, chosen at random,
studies Physics or Chemistry or both?

Answers

The probability that a student chosen at random studies physics and chemistry or both is  35/41 = 0.85

What is the probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

What is the formula for probability?

The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes.

The Venn diagram shows:

There are 2 students studying both biology and physics.

Six students study biology and chemistry together.

There are 4 students who study physics and chemistry.

There are 5 students who just study physics.

There are 7 students who just study biology.

There are 8 students who just study chemistry.

There are 6 students that study none.

As a result, there are a total of 41 students, which is equal to 2 + 6 + 4 + 5 + 7 + 8 + 3 + 6 students.

There are 21 students who study chemistry, which is equal to 8 + 6 + 3 + 4 students.

The number of students that studies physics is = 14

The number of students that studies chemistry is =  21

Probability  = number of favorable outcomes / total number of outcomes

What is the solution of the linear-quadratic system of equations? { y = x 2 + 5 x − 3 y − x = 2

Answers

The two solutions for the system of equations:

y = x^2+ 5x - 3

y - x = 2

Are:

(-5, -7) and (1, -1)

How to solve the system of equations?

Here we have the following system of equations:

y = x^2+ 5x - 3

y - x = 2

We can replace the first equation into the second one to get:

(x^2+ 5x - 3) - x = 2

x^2 + 4x - 3 = 2

x^2 + 4x - 3 - 2 = 0

x^2 + 4x - 5  = 0

Using the quadratic formula, we will get the solutions:

[tex]x = \frac{-4 \pm \sqrt{4^2 - 4*1*-5} }{2} \\\\x = \frac{-4 \pm 6}{2}[/tex]

The two solutions are:

x = (-4 - 6)/2 = -5

x = (-4 + 6)/2 = 1

To find the values of y, we can evaluate the linear equation:

when x = -5

y - (-5) = -2

y + 5 = -2

y = -2 - 5 = -7

So one solution is (-5, -7)

when x = 1

y - 1 = -2

y = -2 + 1 = -1

The other solution is (1, -1)

What is division?

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The other operations are multiplication, addition, and subtraction.

In mathematics, the division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed.

For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

The division sign, "," or occasionally "/," is used in computer code.

So, we know that: Total seeds are 2700 and the total rows are 9

If there are the same amount of seeds in each row.

Following that, the number of seeds will be put in each row.

= (Total seeds) ÷ (Total rows)

= 2700÷9

= 300

Therefore, using division we know that (D) 2700÷9=300 is the basic fact using which John will get t know how many seeds will be planted in a row.

When Kelsey is not on the moving sidewalk, she can walk the length of the sidewalk in 3 minutes. If she stands on the sidewalk as it moves, she can travel the length in 2 minutes. If Kelsey walks on the sidewalk as it moves, how many minutes will it take her to travel the same distance? Assume she always walks at the same speed.

Answers

Answer:

1.2 minutes

Step-by-step explanation:

Kelsey moves 1/3 length per minute. The sidewalk moves 1/2 length per minute. Walking on the sidewalk, Kelsey moves (1/3+1/2) = 5/6 lengths per minute, or 6/5 minutes per length.

The percentage of all graduates who plan to enter the workforce and reside locally is 15%.

According to the tree diagram, we need to calculate the percentage of high school graduates who plan to enter the workforce and reside locally. To calculate this, we need to follow the branches in the tree diagram. Let's start from the top:

1. The first branch shows that 30% of high school graduates plan to enter the workforce.

2. From those 30%, 50% plan to reside locally.

3. To calculate the percentage of all graduates who plan to enter the workforce and reside locally, we need to multiply the percentages from steps 1 and 2 together: 30% * 50% = 0.30 * 0.50 = 0.15 or 15%.

Therefore, the percentage of all graduates who plan to enter the workforce and reside locally is 15%.

The line parallel to the given line 2x+2y=-12 is also -1.

Define slope.

Slope of a line refers to the measure of the steepness and the direction of a line.

Illustrate y= m x+ c.

y = mx + c refers to an equation of a line having a gradient of m and a y-intercept of c. This equation is often referred to as the slope-intercept form of the equation of a line.

We know that,

The general equation of a line is y=m x+ c,

where m = slope and b = y-intercept, c is a constant

Now, the equation of the given line is,

2x+2y=-12

⇒x + y=-6

Now expressing the equation in the form of y=m x+ c

So, y=-6-x

Further, on rearranging we get y= (-1) x-6

                                                   y = mx + c

So, according to the equation,on comparing we get

m=-1 and c=-6

On comparing, the slope of the given line is -1.

Since, 'The slopes of two parallel line is always equal'.

Thus, the line parallel to the given line is also -1.

What is meant by Equation ?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.

Since the function in the graph is headed upward , we know the portion of  x²  is positive . And since the highest point of the red line on the y-axis is 2, we can conclude the function represented by the red line is
