Answer:
A. 12.3%
Step-by-step explanation:
Model this as a binomial distribution
where X is the random variable, n is the number of trials, and p is the probability of success.
Therefore,
- X = lambs born male
- n = 60
- p = 0.5
(If the probability of lambs being male and female is equal, then the probability of males being born = 0.5)
The probability that at least 35 lambs will be born male:
It is impossible to answer this question without a given ordered pair. I apologize.
Answer:
- (4x -4)° +x° +(6x-3)° = 180°
- J = 99°
- K = 64°
- L = 17°
Step-by-step explanation:
The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."
__
<h3>equation</h3>
(4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle
<h3>solution for x</h3>
11x -7 = 180 . . . . . . . divide by °, collect terms
11x = 187 . . . . . . . . add 7
x = 17 . . . . . . . . . divide by 11
<h3>angle values</h3>
m∠J = (6x -3)° = (6(17) -3)° = 99°
m∠K = (4x -4)° = (4(17) -4)° = 64°
m∠L = x° = 17°
