Answer:

The second one

Step-by-step explanation:

A function is a group of ordered pairs that do not have the same ordered pair. The second one has 2 fives in the x coordinate, therefore the second one is not a function

Answer:

w =2.5

Step-by-step explanation:

the area of the triangle is 6*5 divided by half which is 15. this means that the area of the rectangle is also 15. so to find the value of the width we have to divide the area by the known value to get our answer. 15/6 is equal to 2.5 so that's what the value of w is.

Answer:

P₂  = [tex]\frac{P_{1} V_{1} }{V_{2} }[/tex]  

Step-by-step explanation:

Given expression:

     Boyle's law:

             P₁ V₁   = P₂ V₂

Problem is to find P₂;

Solution:

              P₁ V₁   = P₂ V₂

 To solve this problem, multiply both sides by [tex]\frac{1}{V_{2} }[/tex];

   P₁ V₁  x   [tex]\frac{1}{V_{2} }[/tex]; = P₂ V₂  x  [tex]\frac{1}{V_{2} }[/tex];

     [tex]\frac{1}{V_{2} }[/tex] cancels out V₂ on the right hand side;

              P₂  = [tex]\frac{P_{1} V_{1} }{V_{2} }[/tex]

Answer:

-5/8

Step-by-step explanation:

Answer:

- 1 and 15

Step-by-step explanation:

Substitute x = 2 and x = - 2 into f(x)

f(2) = - 4(2) + 7 = - 8 + 7 = - 1

f(- 2) = - 4(- 2) + 7 = 8 + 7 = 15

Answer:

Multiply both numbers by 10 and create a fraction. Then simplify that fraction by dividing both top and bottom by the greatest common factor.

Step-by-step explanation:

Treating 3 1/2 as 3.5 you could set up the fraction as such.

3.5 x 10 = 35

21 x 10 = 210

so you have the fraction 35/210. The GCF of the top and bottom is 35. There is one 35 in 35 and six 35s in 210

So the fraction in the simplest form is 1/6. So the quotient is 1/6.

Answer:

The company manufactures 5 delta cars, 8 beta cars and 12 sigma cars.

Step-by-step explanation:

let in the motor company x number of delta cars, y number of beta cars and z number of sigma cars are manufactured.

from the condition given in the question we can write

9x + 13y + 9z = 257 ........ (1)

4x + 6y + 4z = 116 ........... (2) and    

3x + 4y + z = 59 ......... (3)

From equation (2) we get

9x + 13.5y + 9z = 261 ....... (4) {Multiplying with  both sides}

solving equations (1) and (4) we get

0.5y = 4

and ⇒ y = 8.

from equation (2) putting the value of y we get,  

4x + 4z = 116 - 48 = 68

⇒x + z = 17 .....(5)

Now, from equation (3) putting y = 8 we get,  

3x + z = 59 - 32 = 27 ....... (6)  

hence, solving equations (5) and (6) we get, 17 - x = 27 - 3x

⇒ 2x = 10

⇒ x = 5  

So, z = 17 - x = 12

therefore, the company manufactures 5 delta cars, 8 beta cars and 12 sigma cars.

Answer:

Jason would have to work 60 hours.

Step-by-step explanation:

The equation you would use would be 450 + 12.50t = 1200.

1200 is the money needed, 450 is a constant factor, but the 12.50 changes depending on how many hours Jason works.

You will have to use inverse operations so you would go 450 + 12.50t - 450 = 1200 - 450. That equals 12.50t = 750. Then you divide 12.50 by 750 because 12.50t is multiplying. 750 ÷ 12.5 = 60. So Jason has to work 60 hours!

Answer:

3(34) + 20 -> Angle 6 = 122

2(34) - 10 -> Angle 3 = 58

Step-by-step explanation:

Since measure of angle 2 is equal to measure of angle 6, and measure of angle 7 is equal to measure of angle 3, we can determine the angle measures for angle 3 and angle 6.

First, we solve for x by adding together the two equations and setting it equal to 180 because of the supplementary angles theorem.

3x + 20 + 2x - 10 = 180

Combine like terms.

5x + 10 = 180

Subtract 10, then divide by 5 on both sides.

5x = 170

x = 34

Now we can plug the x value into the equations.

3(34) + 20 -> Angle 6 = 122

2(34) - 10 -> Angle 3 = 58

Answer:

x=1/3

Step-by-step explanation:

The variance of the set  { 2 , 6 , 8 , 3 , 7 , 9 , 1 , 4 } is 7.5

What is Variance?

Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean. Variance is a measure of dispersion, meaning it is a measure of how far a set of numbers is spread out from their average value

Given data ,

The set S = { 2 , 6 , 8 , 3 , 7 , 9 , 1 , 4 }

Step 1 :

To calculate the mean ,

Mean = Sum of Observations / Number of Observations

         = ( 2 + 6 + 8 + 3 + 7 + 9 + 1 + 4 ) / 8

         = 40 / 8

         = 5

Step 2 :

Take each difference from mean and square it

( 2 - 5 )² = 9

( 6 - 5 )² = 1

( 8 - 5 )² = 9

( 3 - 5 )² = 4

( 7 - 5)² = 4

( 9 - 5 )² = 16

( 1 - 5 )² = 16

( 4 - 5 )² = 1

And Sum of 9 + 1 + 9 + 4 + 4 + 16 + 16 + 1 = 60

Step 3 :

Variance = The mean of squared difference

               = 60 / 8

               = 7.5

Hence , the variance is 7.5
