As we can see, both equations have the same slope but different y-intercepts. This means that both lines are parallel.

If both lines had the same slope and the same y-intercept, they would be essentially the same line, and that would mean infinite solutions.

But, we have the same slope and different y-intercepts. This means that the lines are parallel, and thus have no solution.

Your answer is B. No Solution.

Y = 6x + 9

y = 6x + 2

Therefore  y = 6x + 9 = 6x + 2

6x + 9 = 6x + 2

6x - 6x  = 2 - 9

0 =  -7.              This is not true.

So there is:

Two angle measures in a triangle is 81 and 62 what is the missing angle
tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

Let the missing angle be x then .,

81 + 62 + x = 180 (being sum of angles of triangle )

143 + x = 180

x = 180 - 143

x = 37

<em>Therefore the missing angle is 37</em>

Mean: 65

MAD: 6.4

2.

Mean: 60.5

MAD: 6.4

3. The diference of the means are 4.5

I’m sorry, I do not understand the last one.

Step-by-step explanation:

The mean is the average, add all of the values and divide the result by the number of values. The MAD is the mean absolute deviation. You find it by taking the distance between the values and the mean. You then add them together and divide it by the mean. I really hope this helps you!

The manager of a theater noted that for every 10 admission tickets sold, the theater sells 3 bags of popcorn at $2.25 each, 4 so
Shalnov [3]

Answer:

$1.475 is the average amount of snack sales per ticket sold.

Step-by-step explanation:

We are given the following in the question:

Number of popcorn bags sold = 3

Cost of  a popcorn bag = $2.25

Total cost of popcorn bag = 2.25\times 3 = $6.75

Number of soda sold = 4

Cost of  a soda = $1.50

Total cost of soda = 1.50\times 4 = $6.00

Number of candy bars sold = 2

Cost of  a candy bar = $1.00

Total cost of candy bars =  1.00\times 2 = $2.00

Total sales =

Total cost of popcorn + Total cost of soda + Total cost of candy bar

= 6.75 + 6 + 2\\=\$14.75

\text{Average} = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Average amount of snack sales per ticket sold =

\dfrac{\text{Total sales}}{\text{Number of tickets}} = \dfrac{14.75}{10} = 1.475

Thus, $1.475 is the average amount of snack sales per ticket sold.
