I put a condensed version of this answer in the comments, but here is the full version.

Answer:

19.5

Step-by-step explanation:

The dots on the chart show the frequency of the numbers.

For example, 16 is only listed once while 22 is featured twice.

List all of the numbers:

16, 17, 17, 17, 17, 19, 19, 19, 19, 21, 22, 22, 23, 25

Now find the mean.

Mean = the average of all the numbers in a data set

To find the mean add all of the numbers, then divide by the number of numbers in the data set.

Add:

16 + 17 + 17 + 17 + 17 + 19 + 19 + 19 + 19 + 21 + 22 + 22 + 23 + 25 = 273

Divide:

There are 14 numbers, so divide by 14.

273/14 = 19.5

Therefore, the mean is 19.5

juin [17]

Answer:

The farmer bought 36 pigs in all.

Step-by-step explanation:

Given that a farmer bought a number of pigs for $ 160, but, however, 8 of them died before he could sell the rest at a profit of 6 per pig, and his total profit was $ 8, to determine how many pigs did he originally buy the following calculation must be performed:

160 + 8 = 168

168/6 = 28

28 + 8 = 36

Thus, the farmer bought 36 pigs in all.

Please help I am terrible at algebra

Marina CMI [18]

Answer:

y = (x-0)^2 + (-5) ⇒ y = x^2 - 5

Step-by-step explanation:

The general vertex form of the parabola y = a(x - h)² + k

Where (h,k) is the coordinates of the vertex.

As shown at the graph the vertex of the parabola is the point (0, -5)

So,

y = a(x-0) + (-5)

y = ax^2 - 5

To find substitute with another point from the graph like (1,-4)

So, at x = 1 ⇒ y = -4

-4 = a * 1^2 - 5

a = -4 + 5 = 1

<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
