Question 2 is 250 idk about 4
The range of a graph is the high-and-low points of the graph on the y-axis.
The high point looks like it is at y = 5. The low point appears at y = - 9
Option D is your answer.
We need to change the English writing into an inequality.
We know that a number "n" added to 7 is less than or equal to 9.
This can be written as follows:
n + 7 <span>≤ 9
Now, we will isolate the "n" at one side of the inequality. We will do this by subtracting 7 from both side as follows:
n + 7 - 7 </span><span>≤ 9 - 7
n </span><span>≤ 2</span>
To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps
