Answer:
P(X = 4) = 0.1876
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this question:
We want P(X = 4). So
<h2>
Hello!</h2>
The answer is:
The second option,
<h2>
Why?</h2>
We are working with a right triangle, it means that we can use the following trigonometric property:
Which applied to our problem, will be:
We are given:
m∠S, equal to 21°
The side TU (opposite) equal to 5 units.
So, substituting and calculating we have:
Hence, the answer is the second option
Have a nice day!
Answer:
7.6
Step-by-step explanation:
radius is half the diameter so multiply 3.8 times 2.
4y + 5 = -31
4y = -31 - 5
4y = -36
y = -36 / 4
y = -9
