Answer:
P [ K > 3.95] = 0.5633
Step-by-step explanation:
The interpretation of the given question goes thus;
Suppose that K is a random variable
P[-3.95 ≤ K ≤ 3.95] = 0.725
where; P [ + 3.95 < K ] = P [K < - 3.95]
P[K< 3.95] - P [K > - 3.95] =0.725
P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725
P[k < 3.95] - 1 + P [ K < 3.95] = 0.725
3.95 P [ K < 3.95] -1 = 0.725
3.95 P [ K < 3.95] = 1.725
P [ K < 3.95] = 1.725/3.95
P [ K < 3.95] = 0.4367
P [ K > 3.95] = 1 - P[K< 3.95]
P [ K > 3.95] = 1 - 0.4367
P [ K > 3.95] = 0.5633
Number of ways = 4! = 4 x 3 x 2 x 1 = 24
Answer: 24
Im not too sure so dont take my word.
But if you're rounding the fraction to half or whole.
I would round down from 8/14 , to 7/14.
Which 7/14 simplified is 1/2
Your answer is 7/14 i believe
Answer:
(-3,4)
Step-by-step explanation:
Y - 4 = -2(x + 3)
Let x = -3
Y - 4 = -2(-3 + 3)
Y - 4 = -2(0)
Y -4 =0
Add 4 to each side
Y -4+4 =0+4
Y= 4
