Answer:
y=4/3x - 5
Step-by-step explanation:
Answer: -(22/4)
Step-by-step explanation:
Answer:
0.0064
0.00032
Step-by-step explanation:
Given the details:
P(X > 3), n = 5, p = 0.2
The binomial distribution is related using the formula:
P(x = x) = nCx * p^x * q^(n-x)
q = 1 - p = 1 - 0.2 = 0.8
P(X > 3) = p(x = 4) + p(x = 5)
P(x = 4) = 5C4 * 0.2^4 * 0.8^1 = 5 * 0.2^4 * 0.8^1 = 0.0064
P(x = 5) = 5C5 * 0.2^5 * 0.8^0 = 1 * 0.2^5 * 0.8^0 = 0.00032
prob( it lands on open end) = 8/20 = 2/5
prob ( lands on closed end) = 4/20 = 1/5
The second choice is correct.
Answer:
Step-by-step explanation:
-0.25x+1.75x<-1.75+2.5 x
sift terms containing x to right and constant term to left
1.75<2.5 x+0.25x-1.75 x
1.75<2.75x-1.75x
1.75<1.00 x
or 1.75 <x
or x>1.75
