Using the binomial distribution, it is found that the probabilities are:
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Exercise 1:
The parameters are:
n = 15, p = 0.4, x = 4.
Then:
Exercise 2:
The parameters are:
n = 12, p = 0.2, x = 2.
Then:
Exercise 3:
The parameters are:
n = 20, p = 0.05.
The probability is:
Using the binomial formula for each value and adding them:

When multiplying or dividing with negative and positive numbers, if the signs are the same, the result is positive...when the signs are different, the result is negative.
so a positive divided by a negative results in a negative...because the signs are different.
but if it was a negative divided by a negative or a positive divided by a positive the result would be positive because the signs are the same.
Answer:
below given!
Step-by-step explanation:
1) mean = (7.4 + 5.8 + 7.3 + 7 + 8.9 + 9.4 + 8.3 + 9.3 + 6.9 + 7.5 + 9 + 5.8 + 5.5 + 8.6 + 9.3 +3.8) / 16
mean = 7.47
Step-by-step explanation:
Convert the equation to the slope-intercept form (y = mx + b):
<em>subtract 5x from both sides</em>
<em>divide both sides by (-4)</em>
Choose any three values of x and calculate the values od y:
for x = -2:
for x = -6
for x = 2:
