Answer:
Explanation:
You draw a vertical line going upward from<em> x = -1</em>, stop where your vertical line intercetpts the <em>function</em> (the red line); then draw a horizontal line unitl you reach the y-axis; finally, you can read the y-value on the y-axis. That is the value of the function.
It is pretty close to the midpoint between y = 1 and y = 2, thus a good estimate would be y = 1.5.
The pattern is adding 1.43 to the term before
1.11 + 1.43 = 2.54 + 1.43 = 3.97 + 1.43 = 5.40 . . .and so on.
Answer:
B
Step-by-step explanation:
The answer is option B
When drawn option B looks like the image
it crosses at the points (-1,-3), (0,-2),(2,0)
rearranging the equations and drawing a table graph shows how to draw the lines
The Solution:
Given:
Required:
Find the standard deviation of the probability distribution.
Step 1:
Find the expected value of the probability distribution.
Step 2:
Find the standard deviation.
Thus, the standard deviation is 1.60
Answer:
1.60
