Answer:
slice priced $1.50 is better value
Step-by-step explanation:
Angles around a point add up to 360°
Area of a circle = πr²
360° ÷ 60° = 6
⇒ This slice is 1/6 of the whole pizza
⇒ area of the slice = (1/6)π × 6² = 6π in²
⇒ $1.50 ÷ 6π = $0.079577... per in²
360° ÷ 45° = 8
⇒ This slice is 1/8 of the whole pizza
⇒ area of the slice = (1/8)π × 7² = (49/8)π in²
⇒ $1.70 ÷ (49/8)π = $0.088347.. per in²
Therefore, the slice priced $1.50 is cheaper per in²
Answer:
y = 2x - 3
Step-by-step explanation:
The y-intercept is -3 because that is where the line hits the y-axis.
The slope is 2 because from 1 point the the next, you go up 2 right 1.
Using the binomial distribution, there is a 0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.
<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.
For this problem, the values of the parameters are:
p = 0.5, n = 13
The probability that at most eleven of the thirteen babies are girls is:
In which
P(X > 11) = P(X = 12) + P(X = 13)
Then:
So:
P(X > 11) = P(X = 12) + P(X = 13) = 0.0016 + 0.0001 = 0.0017
0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.
