<span>The image gives the interval of the values of a data set. It is the difference between the highest number and the lowest number in a dataset. It summarizes all the values of a data with a single number. (3). Since the data has no outlier, the mean will be the best measure of central tendency to describe the score.</span>
The measures of the angles are given to be x and y. Since y is 65 degrees less than the measure of angle x then, it can also be expressed as x - 65. The sum of the angles x and y should be 180 degrees as they are supplementary angles,
x + y = 180
x + (x - 65) = 180
The value of x is 122.5 and that of y is 57.5. Therefore, the measures of the angles are 122.5 and 57.5.
Given:
Total number of students at Colfax Middle School = 270
Ratio of boys to girls is 5:4.
Total number of students at Winthrop Middle School = 180
Ratio of boys to girls is 4:5.
The two schools hold a dance and all students from both schools attend.
To find:
The fraction of the students at the dance are girls
Solution:
There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4.

Number of boys 
Number of girls 
There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5.

Number of boys 
Number of girls 
Now,
Total number of students in both schools 

Total number of girls in both schools 

The fraction of the students at the dance are girls is



Therefore, the required fraction is
.
Answer: y= -2x + 3
Step-by-step explanation:
Your answer is 7.
I subtracted 5 from 12 to find the missing number for KL that is 7.
Therefore, your answer is 7
