-5 + 4 = -1
start at -5 on ur number line....and since u r adding 4, move 4 spaces to the right and u should arrive at -1
what’s the rest of the question??
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)
The answer is 50/27 or 1 23/27 or approx 1.85185. Here is my work!
Multiply both sides by 10 : 20x + 6x = 50 - x
Collect the like terms: 20x + 6x = 50 - x
Move Variable to Left: 26x + x = 50
Collect like terms: 27x = 50
Divide both sides by 27: 50/27
Hope this helped :))
