If f(x) = -x^3 + 2x^2 - 3,
f(2) = - (2)^3 + 2(2)^2 -3
= -8 +2*4-3
= -8+8-3
= -3
Choice B
A. (4,20)
y=20 5x-2y= -20 5x+3=23
A Is Correct
B. (5,28)
y=28 5x-2y= -31 5x+3= 28
B Is Correct
C. (4,23)
y= 23 5x-2y= -26 5x+3 23
C Is Correct
D. (-5,25)
y= 25 5x-2y= -75 5x+3 = -22
D Is Correct
Answer:
answer is C
Step-by-step explanation:
f(x)= 1/x+1
Answer:
There is no mode in the set
B. Because the mean is less than the median comma this distribution's shape is left dash skewed.
Step-by-step explanation:
Data set = {25, 18, -9, 14,32}
We find sum = 80 hence mean = 80/5 = 16
No mode since nothing is more repeated
Median is the middle entry after arranging in ascending order = 18
a) x bar=16
b) median = 18
c) mode is nil
Here median - mean >1
so negatively skewed
There is no mode in the set
B. Because the mean is less than the median comma this distribution's shape is left dash skewed.
