Which of the following closed sets of ordered pairs is not a function?

A
{(3, 2), (4, 6), (5, 8)}

B
{(2, 1), (3, 2), (4, 3)}

C
{(1, 2), (2, 5), (1, 3)}

D
{(2, 4), (5, 3), (4, 1)}

Answer:

We start with 4 cards. The probability of picking the 4 is 1/4. That card is put back, so we again have 4 cards. The probability of picking the 6 (the number greater than 5) is 1/4.

Therefore, the probability of picking a 4 and then a 6 is (1/4)(1/4) = 1/16.

Answer:

1/16

Step-by-step explanation:

Answer:

6 more times

Step-by-step explanation:

To earn enough money to buy a game that costs $88, Ivan needs to earn 88 / 8 = 11 times his dog walking fee.

He already walked the dog 5 times, so he still needs to walk the dog

11 - 5 = 6 more times.

Therefore, Ivan needs to walk the dog 6 more times to earn enough money to buy the game.

Answer:

Step-by-step explanation:

1. 5/2

Using the two points you do rise over run.

2. zero

Any line that is horizontal is equal to zero (0

3. undefined

Any line that is vertical is undefined

4. The equation always is:

y^2-y^1/x^2-x^1

to find slope.

Label your ordered pairs according to the formula:

x^1 = -12

y^1 = -1

x^2 = -3

y^2 = -4

substitute

y^2-y^1/x^2-x^1

= -12 — -1 / -3 — -4

solve

-12 — -1 = -11

-3 — -4 = 1

-11/1 = -11

5. The equation always is:

y^2-y^1/x^2-x^1

to find slope.

Label your ordered pairs according to the formula:

x^1 = -11

y^1 = -1

x^2 = 7

y^2 = -2

substitute

y^2-y^1/x^2-x^1

= -11 — -1 / 7 — -2

solve

-11 — -1 = -10

7 — - 2 = 9

-10/9

I hope this is right...

Answer:

Beth's class left for the field trip at 7:13 A.M..

Step-by-step explanation:

To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.

The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.

To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.

9:41 A.M. minus 55 minutes is 8:46 A.M..

8:46 A.M. minus 93 minutes is 7:13 A.M..

Therefore, Beth's class left for the field trip at 7:13 A.M..

I hope that helps!

Answer:

6:59am

Step-by-step explanation:

1 hour and 33 minutes = 93 minutes

55 minute ride to museum

93+55=148

60 minutes in 1 hour

148 divided by 60 = 2 hours 46 minutes

Time Left: 9:41

9.41-2.46

6.59

They left at 6:59am

Answer:

The answer is D.

Step-by-step explanation:

y = mx + b

C = 5/9 (F - 32)

C = 5/9F - 5/9 (32)

Option (D) is correct.

Answer:

Step-by-step explanation:

Rise over run is the slope, m

m=2/5

a)  the slope is 2/5 = .4 which is below the boundary guideline.  So no this is not with in carpenter's guidelines

b) the image below show a line with slope 2/5 but with intercept 3

c) the stairs can be draw on the line with rise 2 run 5   from the line.  see image

d)equation is in image

2.

a) count the squares

horizontal distance =3

vertical distance =3

b)  slope is vertical distance over horizontal distance  so m= 3/3 =1

Answer:

107°

Step-by-step explanation:

the arrow is in between 6 and 8, but it's too thick to see seven underneath it, but I've zoomed in. it's also 107° rather than 73° because the angle is larger than 90° and starts on the left

As in how to determine it, first look at which side it's on first, if the Angle is bigger than 90° (the corner of a square) and which side it's on, if it's on the left it means u are using the top row of numbers, if it's on the right but at 107° however, it means u are using the wrong row of numbers.

Answer:

31t 2,446 lb 2oz

Step-by-step explanation:

24t+7t=31t

1,507+938=2,445 lb

12 oz+6 oz=18 oz = 1 lb + 2oz (16 oz in a pound)

31t+2,445 lb+1 lb + 2oz=

31t 2,446 lb 2oz

Answer:

Greater than for both i believe

Step-by-step explanation:

Answer:Yea both a greater than because if you do 2 x 5/2 it = 5 and 5 is a hole number 5/2 is not and 2 is a hole number but 5 is greater than 2.

Step-by-step explanation:

Answer:

   The original length of the board is 8 feet.

   The length that was cut off is 2 feet.

   One possible equation we can use is: x = 8 - 2, where x represents the length of the board that is left. Solving for x, we get x = 6 feet.

   The length of the board that is left is 6 feet.

Step-by-step explanation:

We are given that the board was originally 8 feet long. Bryce cuts off 2 feet from the board to use for a project. Therefore, the length of the board that is left is 8 - 2 = 6 feet.

To solve this problem algebraically, we can set up an equation where x represents the length of the board that is left. We know that the original length of the board is 8 feet, and 2 feet was cut off, so we can write:

x = 8 - 2

Simplifying this equation gives us:

x = 6

Therefore, the length of the board that is left is 6 feet.

Answer:12/15 and 8/10 do have the same value, if you were to take the two fractions and simplify them into decimals both answers would be 0.8.

Answer: yes they are the same

Step-by-step explanation:

Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

Answer:

60

Step-by-step explanation:

the reason for this is because the straight line is 180 and 100+20=120. So you would subtract 180-120 and you would get 60.

Answer:

Step-by-step explanation:

 The temperature at 11:00 a.m. was -8.4°C_. This is reasonable because the temperature decreased by -0.6°C each hour, meaning the ending temperature was 1.8°C lower than the beginning temperature.

Answer:

x = - 2

Step-by-step explanation:

3(5x + 2) - 7(3x - 4) = (5 - 9x)2

15x + 6 - 21x + 28 = 10 - 18x

34 - 6x = 10x - 18

-12x = 24

x = -2
