Answer:
c. 0.219
Step-by-step explanation:
If the coin is fair, then the probability of flipping a head is 1/2 = 0.5
Therefore, we can model this as a binomial distribution:
X ~ B(n, p) where n is the number of events and p is the probability of success
Given:
X ~ B(8, 0.5)
Using a calculator:
P(X = 5) = 0.21875 = 0.219 (3 dp)
Using the formula:
(where n is the number of events, x is the number of desired successes and p is the probability of success)
That's Be 40-3 squared , 40-27 = 13
Answer:
x-intercept = (-4/35, 0)
y-intercept = (0, 4).
Step-by-step explanation:
x intercept occurs when y = 0 so
35x + 4 = 0
x = -4/35.
Y - intercept ( when x = 0):
y = 35(0) + 4 = 4.
