Answer:
The answer to your question is in the picture below
Step-by-step explanation:
y + 3/4x < 2
y+ 3/4x = 2
y = -3/4x +2
Interceptions (0,2) and (8/3, 0) It's a dotted line and we are interested in the area below the line
y - 1 ≥ 2x
y - 1 = 2x
y = 2x + 1 Interception, it's not a dotted line with interceptions (0,1) and (-1/2, 0), we are interested in the area up the line.
Answer:
0.1527
Step-by-step explanation:
Given that a researcher wishes to conduct a study of the color preferences of new car buyers.
Suppose that 50% of this population prefers the color red
15 buyers are randomly selected
Let X be the no of buyers who prefer red.
X has exactly two outcomes red or non red.
Also each buyer is independent of the other
Hence X is binomial with p = 0.5 and n = 15
Required prob =The probability that exactly three-fifths of the buyers would prefer red
= P(X=9)
=
=
