If it takes 5 hours for Felicia's phone to get to 1%, it will take x hours to get to 100%.

We need to find x.

So we can simply just say 5 • 100.

X = 500

So it would (unfortunately) take Felicia's phone 500 hours to get to 100%.

### 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?

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.

He hopes to win a free drink, a free dessert, or free fries. He says, “The probability that I get what I want is 1 out of 3, because there are 3 sections I want the arrow to land in.” Unfortunately, A.J. is incorrect. What is his actual probability of getting one of the three things he wants? What did he do wrong? How did you calculate the correct answer? Answer all three questions in complete sentences.

The actual probability of getting one of the three things he wants is 3/total number of sectios.
He thought it as since he needs to get 1 out of three items, so he did 1/3.
To get the correct answer, the number of items needed is divided with the total number of sections.

### Find the value of "a" for which the graph of the first equation is perpendicular to the graph of the second equation. 1) equation : y=a/3x-6 2) equation 4x+2y=6 Their is the same problems but different equation.1) 3y+ax=8 2)3/4x+2

Perpendicular lines will have negative reciprocal slopes. Example : if u r given a slope of 1/3, to find the negative reciprocal, flip the slope and change the sign. So the negative reciprocal of 1/3 is -3/1 or just -3. So slope 1/3 and slope -3 are perpendicular.
==================
equation 2 :
4x + 2y = 6
2y = -4x + 6
y = -2x + 3...the slope here is -2....a perpendicular line will have a slope of 1/2.

y = (a/3)x - 6......so we have to make a/3 = 1/2......1.5/3 = 1/2
so a = 1.5
===================
eq. 2 : 3/4x + 2
not sure what the entire equation is.....but it looks to have a slope of 3/4. That means a perpendicular line will have a slope of -4/3.

3y + ax = 9
3y = -ax + 9
y = (-a/3)x + 3.....therefore, a has to be 4
