1. I feel the need to explain things first before I write the numeric value. 
   Let x be the total number of students in the school. 25% of this value is given to be 35.
                        (0.25)x = 35
The value of x is 140. 75% of this value is the answer which is equal to 105.

2. Let y be the alternative schools. With this, the number of charter schools is 2x - 6 which is equal to 52 
                              2x - 6 = 52
The value of x is 29. Therefore, there are 29 charter schools.

The Dot plots below show the number of sales made by Jason and Shane at work over the past seven days. Which observation about t
IgorLugansk [536]

Jason's data distribution is symmetrical and shows no outliers; Shane's data distribution is uniform and shows no outliers also. Therefore, the correct observation about the data sets that is correct is:<em> Option B.</em>

<h3>Symmetrical and Uniform Data Distribution on a Dot Plot</h3>
  • If the data plotted on the dot plot shows a bell shape curve and can be divided into equal halves by a vertical line, the data distribution is symmetrical.
  • When the data is spread equally across the range with no clear peaks, the data distribution is uniform.

<h3>What are Outliers?</h3>

Outliers are values that are far from the middle and are entirely different from the rest of the data.

The dot plots for sales made by Jason and Shane are shown in the image attached below.

Jason's data distribution is symmetrical and shows no outliers; Shane's data distribution is uniform and shows no outliers also. Therefore, the correct observation about the data sets that is correct is:<em> Option B.</em>

A note with a face value 4300 was discounted at 3%. if discount was 21 dollars. find the length of loan in days
Doss [256]
The annual discount is 3%, therefore the total discount for 1 year would be:

4300 × 3 ÷ 100 = 129$

Now, you can set a proportion:

discount : annual discount = loan days : days in one year
21 : 129 = x : 360
 
x = 21 × 360 / 129 = 58.6 days

Hence, the loan duration was 60 days.
