A study conducted at a certain college shows that 51% of the school's graduates find a job in their chosen field within a year after graduation. Find the probability that 5 randomly selected graduates all find jobs in their chosen field within a year of graduating. Round to the nearest thousandth if necessary.

Answer:

4x + y = 1

Step-by-step explanation:

Start with the familiar format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

With a slope of -4, we can write:

y = -4x + b

We need to find a value for b that forces the line through point (1,-3).  This is done by entering this point in the equation and solving for b:

y = -4x + b

-3 = -4*(1) + b

b = 1

The equation is y = -4x + 1,  This can be rewritten as:

4x + y = 1

Answer: B. 150°

Step-by-step explanation:

The angle is obviously obtuse and is therefore greater than 90°.

This rules out A. and C.

Also, this angle is not 180° because then it would be flat.

The number of blue marbles in the bag is 18.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Probability of choosing a green marble = total number of green marbles / total number of marbles

0.55 = 22/x

x = 22 / 0.55

x = 40

Total number of blue marbles = 40 - 22 = 18

Answer:

[tex]tan(\alpha)=-\frac{\sqrt{35}}{5}[/tex]

Step-by-step explanation:

Tan can be defined as: [tex]\frac{sin(\theta)}{cos(\theta)}[/tex] as it simplifies to opposite/adjacent. If you know a bit about the unit circle, you'll know that the x-coordinate is going to be cos(theta) and the y-coordinate is going to be sin(theta). Since the sin(theta) is defined as opposite/hypotenuse, and the hypotenuse = 1, so sin(theta) is defined as the opposite side, which is the y-axis. Same thing goes for cos(theta), except the adjacent side is the x-axis.

Using this we can define tan

[tex]sin(\alpha)=-\sqrt{7}\\cos(\alpha)=\sqrt{5}\\\\tan(\alpha)=-\frac{\sqrt{7}}{\sqrt{5}} * \frac{\sqrt{5}}{\sqrt{5}}\\tan(\alpha)=-\frac{\sqrt{7*5}}{5}\\tan(\alpha)=-\frac{\sqrt{35}}{5}\\[/tex]

Answer:

tan α = -√35/5

The value of c is 3

The complete question is in the attached image

The function definition is given as:

g(x) = f(x) - c

From the graph of functions f(x) and g(x), we can see that:

f(x) is shifted down by 3 units to get to g(x)

This means that:

g(x) = f(x) - 3

By comparing g(x) = f(x) - 3 and g(x) = f(x) - c,

We have:

c = 3

Hence, the value of c is 3

Answer:

Area of triangle = (base x height)/2

There are all together 4 triangles and 1 square.

Therefore, surface area = area of square + 4 x area of triangle

height = 5.8 in, base = 6 in. area of square = 6x6 = 36 in^2.

area of 1 triangle = (5.8x6)/2

area of 4 triangles = 2x5.8x6 = 69.6 in^2

surface area = 69.6 + 36 = 105.6 in^2

Given Chef uses 5 cups of cake batter for 1 cake and 4 cups of batter for 1 batch of cupcakes. Chef wants to make at least 4 cakes. Profit on 1 cake is $35 and $30 for 1 batch of cupcake.

let the number of cakes be x and the number of batches of cupcakes be y such that

5x+4y<=40--------1

-x=-4

multiply second equations by 5

-5x=-20-----------4

now  add 3 and 4

5x+4y-5x=40-20

The correct rows in the inequalities are

The rows are given as:

-3x - 4 < x + 4  ⇒ -3x < x

2(x - 5) + 1 ≤ 5  ⇒ 2(x - 5) ≤ 4

-4x ≥ -24  ⇒ x ≤ 6

x = 2y and 2x + 2y > 60  ⇒ 6y > 60

y + 2 ≤ 4 - x and 4 - x ≤ 3y  ⇒ y + 2 ≤ 3y

To determine the correct rows, we simply solve each inequality.

This is done as follows:

-3x - 4 < x + 4

Collect like terms

-3x - x < 4 + 4

Evaluate the like terms

-4x < 8

Divide by -4

x > -2

This means that:

-3x - 4 < x + 4  ⇒ -3x < x is false.

2(x - 5) + 1 ≤ 5  

Subtract 1 from both sides

2(x - 5) ≤ 4

This means that:

2(x - 5) + 1 ≤ 5   ⇒ 2(x - 5) ≤ 4 is true.

-4x ≥ -24  

Divide through by -4

x ≤ 6

This means that:

-4x ≥ -24  ⇒ x ≤ 6 is true.

x = 2y and 2x + 2y > 60

Substitute 2y or x in 2x + 2y > 60

2(2y) + 2y > 60

Evaluate the product

4y + 2y > 60

Evaluate the like terms

6y > 60

This means that:

x = 2y and 2x + 2y > 60  ⇒ 6y > 60 is true.

y + 2 ≤ 4 - x and 4 - x ≤ 3y

We have:

y + 2 ≤ 4 - x and 4 - x ≤ 3y

This can be rewritten as:

y + 2 ≤ 3y

This means that:

y + 2 ≤ 4 - x and 4 - x ≤ 3y  ⇒ y + 2 ≤ 3y is true

Hence, the correct rows are 2, 3, 4 and 5

Answer:

they are no instructions so no answers either.

Step-by-step explanation:

am sorry I can't help you, the question might not have been complete. please do contact me when it's.

Considering the given information in the question, the value of x is [tex]12^{o}[/tex], and that of y is [tex]7.5^{o}[/tex].

A transversal is a line that cuts through two given parallel lines. Thus it intersects each parallel line at a point, forming four angles each.

From the given information in the question, it can be inferred that:

the given bottom right angle of the first intersection and the bottom right angle with the second intersection are congruent (corresponding angle property).

So that,

[tex](5x+4y)^{o}[/tex] = [tex](12y)^{o}[/tex]

[tex]5x^{o}[/tex] = [tex]12y^{o}[/tex] - [tex]4y^{o}[/tex]

[tex]5x^{o}[/tex] = [tex]8y^{o}[/tex]............ 1

Also given that the top right angle at the second intersection is a right angle, then;

    [tex]12y^{o}[/tex] + [tex]90^{o}[/tex] = [tex]180^{o}[/tex] (sum of angles on a straight line)

This implies that;

    [tex]12y^{o}[/tex] = [tex]180^{o}[/tex] -    [tex]90^{o}[/tex]

       [tex]12y^{o}[/tex]  =     [tex]90^{o}[/tex]

So that,

y = [tex]\frac{90}{12}[/tex]

y = [tex]7.5^{o}[/tex]

Thus substituting the value of y in equation 1, we have;

[tex]5x^{o}[/tex] = [tex]8y^{o}[/tex]........ 1

     = 8(7.5)

5x = 60

x = [tex]\frac{60}{5}[/tex]

x = [tex]12^{o}[/tex]

Therefore, x = [tex]12^{o}[/tex] and y = [tex]7.5^{o}[/tex]

( H ⇒ C becomes C ⇒ H )

• Second, we negate the hypothesis and the conclusion.

Then

• first ,if you graduated from high school , then you are in college

• second , If you didn't graduate from High school ,Then you are not in college

The equation which represents the measure of the unknown angles is x + x + 10 =130. Hence, option C is correct.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the data given in the question,

As per the rules, the sum of the three sides of a triangle is 180°.

The angles are x, x+10, and 50.

Now,

x + x + 10 + 50 = 180

x + x + 10 = 180 - 50

x + x + 10 = 130°.

Therefore, the equation option above is the correct answer.
