A) 2 1/2 hours
B) 3 hours
C) 3 1/2 hours
D) 5 hours

Answer:

164 people

Step-by-step explanation:

Let's say x = # of people in night 2 and 3

Average = (n₁ + n₂ + n₃ + ...)/n

Plug in known numbers: (125 + x + x)/3 = 151

Multiply + simplify: 125 + 2x = 453

Subtract: 2x = 328

Divide: x = 164

Final answer:

To determine the number of people who attended the concert on the second and third nights, an equation based on the average attendance was formulated and solved, resulting in 112 people attending each of those nights.

Explanation:

To solve this problem, we need to find out how many people attended the concert on the second and third nights. Since we know the average number of people for the 3 nights was 125 and there were 151 people on the first night, we can set up an equation to find the number attending on the other nights.

Let the number of people who attended on the second and third nights be x each. The total number of people over the three nights is then 151 + x + x (since the same number of people attended the second and third nights). To find this number, we multiply the average number of people (125) by the number of nights (3).

We get the equation:
125 * 3 = 151 + x + x
375 = 151 + 2x
375 - 151 = 2x
224 = 2x
x = 112

Thus, 112 people attended the concert on each of the second and third nights.

Answer:

The corresponding point for the function f(3/4 x) is (12 , -8)

Step-by-step explanation:

* Lets revise the horizontal stretch or compress

- A horizontal stretching is the stretching of the graph away from

 the y-axis

- A horizontal compression is the squeezing of the graph toward

 the y-axis.

# if k > 1, the graph of y = f(k•x) is the graph of f(x) horizontally

 compressed by dividing each of its x-coordinates by k.

# if 0 < k < 1 (a fraction), the graph y = f(k·x) is the graph of f(x)

  horizontally stretched by dividing each of its x-coordinates by k.

* Now lets solve the problem

- The function f(x) will be the function f(3/4 x)

∵ The x multiplied by a constant

∴ f(x) stretched or compressed horizontally

∵ f(x) ⇒ f(k · x)

∵ f(x) ⇒ f(3/4 x)

∴ k = 3/4 ⇒ less than 1

∵ 0 < k < 1

∴ f(x) starched horizontally

∴ Divide each of its x-coordinates by k

∵ k = 3/4

∴ Divide each of its x-coordinates by 3/4

∵ Point (9 , -8) is on the graph of f(x)

- Find the corresponding point on the graph f(3/4 x) by dividing

 x-coordinate by 3/4

∵ x = 9

∴ The corresponding x = 9 ÷ 3/4 = 9 × 4/3 = 36/3 = 12

∴ The corresponding point is (12 , -8)

Answer:

b = 8

Step-by-step explanation:

Given  : A triangle with side a= 12 , b = 6.33 and angles.

To find : What is the value of b in this diagam.

Solution : We have given that side a= 12 , b = 6.33

Angle A = 113.17

Angle B = 37.81 .

By the sin law: [tex]\frac{b}{sin B} =\frac{a}{sin A}[/tex].

[tex]\frac{b}{sin( 37.81)} =\frac{12}{sin( 113.17)}[/tex].

[tex]\frac{b}{0.613} =\frac{12}{0.919}[/tex].

On cross multiplication

b * 0.919 = 12 * 0.613 .

b * 0.919 = 7 .356

On dividing by 0.919

b = 8.004

Therefore, b = 8.

Answer:

B

Step-by-step explanation:

The digit 6 in Andrew's number is worth 10 times less than the digit six in the other number. This means that the six will be shifted over one place to the left. The only number with a 6 in that position is B, 462,017.

It's B that's correct.

In 186425, the 6 is 6 thousands or 6000

Twice that amount has to be a digit in the ten thousands place.

When you check the choices, you'll see that the number 462, 017 is exactly 10 times of the value digit 6 of Andrew's number

Step-by-step explanation:

Answer:

least likely option comes out to be option D.

Step-by-step explanation:

correct answer is option D.

As in the question it is given that the average salary of one group is  $53,000.

and,

it is also stated that the  sampling variability is very low which means the deviation from the mean will be very low .

when look at the options all the option A , B , C  are very much closer to $53,000 and the only option left is $41,000 which is very much deviated

hence,the least likely option comes out to be option D.

Answer:

x=-2

Step-by-step explanation:

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

Distribute

2x -8 = 8x+4

Subtract 2x from each side

2x-2x-8 = 8x-2x+4

-8 = 6x+4

Subtract 4 from each side

-8-4 = 6x+4-4

-12 = 6x

Divide by 6

-12/6 = 6x/6

-2 =x

Answer:

Step-by-step explanation:

The zeros:

(x + 2)(x - 4) = 0 ⇔ x + 2 = 0 or x - 4 = 0

x + 2 = 0          subtract 2 from both sides

x = -2

x - 4 = 0          add 4 to both sides

x = 4

(x + 7) or (x - 2)

Step-by-step explanation:

Given

x² + 5x - 14

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (+ 5)

The factors are + 7 and - 2, since

7 × - 2 = - 14 and 7 - 2 = + 5, hence

x² + 5x - 14 = (x + 7)(x - 2)

I think the awnser should be a.

Step-by-step explanation:

This is because people usally find interests in things that percieve them. Since I am in freshmen I can tell how you feel. If you want to be a leader make choices that affect people personally, and don't make them feel bad.

Answer:

A is the answer.

Step-by-step explanation:

If a high school sophomore randomly declares himself a leader to his classmates, he will have difficulty finding people who will listen to him.

This is because - People are less likely to obey people that are just like themselves.

People are more likely to obey someone who represents authority. This cannot be the answer as the kid has not been declared authority by the school or he is not elected by the students. A random kid self electing himself will not be taken seriously by the kids.

So, option A can be the answer.

Answer:

this gives you 144.5cm^2 and that is your answer

I hope my answer has come to your helpanswerStep-by-step explanation:

The area of the given figure is Option(C) 144.5 square centimeter.

In the diagram given aside, two shapes are mentioned one is a rectangle and other is a right-angled triangle.

The area of the rectangle is given by -  length*breadth

The area of the right-angled triangle is given by -  1/2*base*height

In the given figure, length = 13cm , breadth = 9cm , base = 11cm and height = 5cm

⇒ Total area = length*breadth + 1/2*base*height

⇒ Total area = 13*9 + 1/2*11*5 square centimeter

⇒ Total area = 117 + 27.5 square centimeter

∴  Total area = 144.5 square centimeter

Therefore, the area of the given figure is Option(C) 144.5 square centimeter.

The input value is the x value, and the output value is the y value.

You know y = 5, so you can plug it into the function to find the input:

y = x - 3         Plug in 5 for y

5 = x - 3      Add 3 on both sides

5 + 3 = x - 3 + 3

8 = x

Answer:

8

Step-by-step explanation:

y= x -3

to get the Anwer I got i Subtracted

Because the output value is supposed to be five so?

5= x-3

Well  2 does get 5 if you add 2+ 3 together!

but if you subtract 3 -2 you get 1..

and 5 - 3 = 2 not 5

and adding 8 + 3 is 11 but subtracting it is 5!

which is

5= 8 - 3

NO!

Answer:

1) Second option:  [tex]y=0.25x+2[/tex]

2) Third option: $14,500

Step-by-step explanation:

1) The equation of the line in Slope-intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

You know the point (20,7) of the line and you can observe in the graph that the y-intercept is:

[tex]b=2[/tex]

Then, you can substitute these values into the equation  [tex]y=mx+b[/tex]

and solve for the slope "m":

[tex]7=m(20)+2\\\\7-2=20m\\\\m=\frac{5}{20}\\\\m=0.25[/tex]

Therefore, the equation of this line is:

[tex]y=0.25x+2[/tex]

2) To calculate the total cost of producing 50 engines, you need to substitute [tex]x=50[/tex] into the equation of the line  [tex]y=0.25x+2[/tex]. Then you get:

 [tex]y=0.25(50)+2[/tex]

 [tex]y=0.25x+2[/tex]

 [tex]y=14.5[/tex]

Since the y-axis represents the total cost "y" in thousands of dollar, then the total cost of producing 50 engines is:

$14,500

Answer:

Option B is correct

Step-by-step explanation:

We need to solve the equation 3x^2 = 18 3/4 to find the value of x

3x^2 = 18 3/4

Converting mixed fraction into fraction form

3x^2 = 75/4

Dividing both sides by 3

3x^2/3 = 75/4*3

x^2 = 75/12 (dividing numerator and denominator by 3 which is common factor)

x^2 = 25/4

Taking square root on both sides to find value of x

√x^2 = √25/4

x = ± 5/2

x = ± 2 1/2

So, Option B is correct.
