Answer:
Option D) s = 1
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 69
X = 68
Formula:
Computing z-scores for different standard deviation:
The standard deviation with highest z-score gives the most extreme position in the distribution.
Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.
Option D) s = 1
Find the equation of the line connecting (0, 5) and (-2, 0).
As we go from the first point to the second, x decreases by 2 and y decreases by 5. Thus, the slope of this line is m = rise / run = -5/(-2), or 5/2.
Starting with the general equation of a line in slope-intercept form, y = mx + b, substitute the knowns as appropriate to determine the value of b:
y= mx + b => 5 = (5/2)(0) + b. Then b = 5, and the desired equation is
y = (5/2)x + 5.
Check this! If we subst. the coordinates of (-2,0) into this equation, is the equation true?
0 = (5/2)(-2) + 5
Yes. So, y = (5/2)x + 5 is the desired equation.
Answer:
number 3 is a function, the other one is not a function.
the range for number 2 is -2,0,2,4 and for number 3 the rage is 0,1,2,3
6,11,17,17,19
median is 17
11+17+19+6+17=70
70/5=14
mean is 14
19-6=13
13 is range
The answer is 92. subtract 44 from 136 and you get x = 92
