Answer:
d 0.5282
Step-by-step explanation:
Given the following :
Probability of getting to the bus on time = 70% = P = probability of success = 0.7
(1 - p) = probability of failure = 0.3
Number of trials(n) = 5 days
Number of sucesses (r) = atleast 4 days : >= 4
This is a binomial probability problem
P(r) = nCr × P^r × (1 - P)^(n - r)
P(X >=4) = P(4) + P(5)
P(4) = 5C4 × (0.7)^4 × (0.3)^1 = 0.36015
P(5) = 5C5 × (0.7)^5 × (0.3)^0 = 0.16807
P(4) + P(5) = 0.36015 + 0.16807 = 0.52822
Answer:
see explanation
Step-by-step explanation:
Given
= 
( cross- multiply )
56x = 14 × 16 = 224 ( divide both sides by 56 )
x = 4
Y + 1 = -2(x - 1)
the formula is y-y1=m(x-x1), the variables with the numbers representing the y and x coordinates of the given point, and m representing the slope. just plug in and that’s your equation :)
Answer:
-3
Step-by-step explanation:
divide -72 by 24.
-72 ÷ 24 = -3
