The coordinate grid shows points A through K. What point is a solution to the system of inequalities?
1 answer:
Answer:
Option C.) B
Step-by-step explanation:
we have
y > -2x+10 -----> inequality A
The solution of the inequality A is the shaded area above the dashed line y=-2x+10
The slope of the dashed line is negative m=-2
The y-intercept of the dashed line is (0,10)
The x-intercept of the dashed line is (5,0)
y > (1/2)x-2 -----> inequality B
The solution of the inequality B is the shaded area above the dashed line
y= (1/2)x-2
The slope of the dashed line is positive m=1/2
The y-intercept of the dashed line is (0,-2)
The x-intercept of the dashed line is (4,0)
using a graphing tool
The solution of the system of inequalities is the shaded area
see the attached figure
Points B and I are solution to the system of inequalities

Answer:
0.7569, 0.5729,0.4371
Step-by-step explanation:
Given that the books are of only two types either non dash fiction or fiction.
Also probability of selecting a fiction = 0.87 = p
X - no of books fiction selected is binomial with p = 0.87 and n =2
(since each trial is independent of the other and there are only two trials)
a) the probability that both books are fiction=
b) Here n =4 with same p.
c) Prob atleast one is non dash fiction =
This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.
