Answer:
Angle x is 75 degrees because 180-105 = 75 so the angle next to 105 is the alternate exterior angle to angle x which means they are equal
Step-by-step explanation:
Answer: D. The probability of a time from 75 seconds to 250 seconds.
Step-by-step explanation:
We know that a density curve graph for all of the possible values from a to b can be used to find the the probability of the values from a to b .
Given: A density graph for all of the possible times from 50 seconds to 300 seconds.
Then it can be used to find the the probability of a time in the range from 50 seconds to 300 seconds.
From all the given option only option D gives the interval which is lies in the above range.
i.e A density graph for all of the possible times from 50 seconds to 300 seconds can be used to determine the probability of a time from 75 seconds to 250 seconds.
Here sorry if this doesn't help
Answer:
Step-by-step explanation:
Recall that on the unit circle, each point is represented as
where
. In this case, we are asked to take a loot at the interval
.
We will use the definition of tangent to solve the problem. REcall that

So, in this case, tangent is undefined whenever the denominator is zero. That is, when
. Checking the unit circle with the interval
, this restriction corresponds to the upper half of the unit circle. In this case, the x component of each point is cosine. We are interested at the points where
.
. This happens only at the point (0,1), which is associated with the value of
