# A school sells boxes of cookies each year for a charity fund. The data set shows the number of boxes the 10 families living on Willow Avenue buy, on average, every year. {2, 3, 2, 2, 0, 5, 2, 1, 1, 3} Does this data have negative, positive, or zero skew?

QUESTION POSTED AT 19/02/2020 - 04:25 PM

This data set has zero skew as it is symmetric.

## Step-by-step explanation:

We know that the symmetry exist in a data when the mean, median and mode of the data is same.

i.e. we are given a set of data as:

{2, 3, 2, 2, 0, 5, 2, 1, 1, 3}

• On arranging the data in increasing order we get :

0  1   1   2   2   2   2   3   3   5

Hence, the value that occur in the middle is: 2

Hence, we have Median=2

• Also, the mean is calculated as follows: Hence, Mean=2.1

• Also, the mode of the data is the most frequently occurring data point in the set.

Here 2 occurs most number of times i.e. 4 times and hence we have:

Mode=2

Now, as the Mean, Median and Mode of the data are approximately same.

Hence, we get the data is symmetric and hence has a zero skew.

### The sharadze family is planning a car trip to atlanta, georgia, which is 279 miles from their home. they plan to drive at an average speed of 62 miles per hour. they also plan to stop for lunch for 45 minutes. based on their plan, when should they leave in order to arrive in atlanta at 3:00 p.m.?

The Sharadaze family should leave at 10:45 am.

279(miles)/62(miles)=4.5(min.)  4.5(min.)-45(min.)=4.15

10:45+4:15=2:60 which is 3:00

which proves that the Sharadaze family should leave at 10:45 am.

### The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units

V = 4187 cubic units.

Step-by-step explanation:

Volume of a sphere = 4/3*π*r^3

Given: r = 10, π = 3.14

Volume of the sphere = 4/3*3.14*10^3

= 4/3*3.14*1000

= 4/3*3140

= 12560/3

V = 4186.66

When we round to the nearest whole number, we get V = 4187 cubic units.

Thank you.

Nina used 2 cups. The correct answer is B. Use this formula;
lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.

y = x(8)
Replace y with 16.
16 = x(8)
Divide by 8.
2 = x
Thus, 2 cups.

The general equation of a circle is where a and b are the x and y components of the center respectively. In order to get into this format, we have to use a method that I'm drawing a blank on the same, my apologies about that. Anyway, what you want is to first isolate the variable on side so now you have: (you'll see why I rearranged this soon) Now you have to make it into an equation that can be simplified into the format stated earlier. So, You have to take the x & y terms (-4x & -8y in this case) divide them each by two, and then square them. The result of this step is the equation: Notice the new components that have been added (4 & 16) and how the have been added to both sides. That is an important step.
