Answer:
And using this formula we have this:
Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917
Step-by-step explanation:
Let X the random variable of interest that a woman must wait for a cab"the amount of time in minutes " and we know that the distribution for this random variable is given by:
And we want to find the following probability:
And for this case we can use the cumulative distribution function given by:
And using this formula we have this:
Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917
Answer:
B) 34°
Step-by-step explanation:
149 - 115 = 34°
Exterior angle = sum of other interior angles
Function tangent of an angle in a right triangle equals
- opposite side / adjacent side
- sine of the angle / cosine of the angle
For this reason, all answers choices are correct except the fourth one, which is the cotangent of angle PAB.
Answer: OPTION B.
Step-by-step explanation:
Given the equation 
you can find an equivalent equation by simplifying it.
You need to remember the multiplication of signs:
Now you can apply the Distributive property:
Simplifying the equation, you get:
You can observe that this equivalent equation matches with the equation provided in option B.
