The "mean" of a group of numbers is also called their "average".

To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.

Step #1:  Addum up:  3+7+2+9+4+7+3+7+5+2 = 49

Step #2:  Count the number of items on the list:  I count 10 .

Step #3:  Divide the sum by the number of items on the list.

                 49 / 10  =  4.9

The mean (average) of the numbers on that list is  4.9 .

First to find the mean of the numbers we have to add the all up
3 + 7 + 2 + 9 + 4 + 7 + 3 + 7 + 5 + 2 = 49
Then we have to divide by how many numbers we have which is 10
49 divided by 10 equals 4.9
4.9 is the mean of the data set.

if 99 certons of milk was sold and 45 of them were regular flavor what is the ratio of chocolate milk sold to regular milk sold+
andreyandreev [35.5K]
Well 99 cartons sold, and 45/99 were normal
therefore 99-45 = 54
the ratio is 54:45 if they ask for chocolate to normal
wording of the question is crucial
I'm not sure if you can cancel the ration down to 6:5, you probably can

What are the approximate values of the minimum and maximum points of f(x) = x5 − 10x3 + 9x on [-3,3]? A. maximum point: (–2.4, 3
slava [35]

Answer:

(-2.4, 37.014)

Step-by-step explanation:

We are not told how to approach this problem.  

One way would be to graph f(x) = x^5 − 10x^3 + 9x on [-3,3] and then to estimate the max and min of this function on this interval visually.  A good graph done on a graphing calculator would be sufficient info for this estimation.  My graph, on my TI83 calculator, shows that the relative minimum value of f(x) on this interval is between x=2 and x=3 and is approx. -37; the relative maximum value is between x= -3 and x = -2 and is approx. +37.  

Thus, we choose Answer A as closest approx. values of the min and max points on [-3,3].  In Answer A, the max is at (-2.4, 37.014) and the min at (2.4, -37.014.

Optional:  Another approach would be to use calculus:  we'd differentiate f(x) = x^5 − 10x^3 + 9x, set the resulting derivative = to 0 and solve the resulting equation for x.  There would be four x-values, which we'd call "critical values."
