Answer:
The required probability is
Step-by-step explanation:
Consider the provided information.
We need to find the probability that the first flip results in a head.
Therefore probability of lending head is
The first flip is head can be calculated as:
Integrate the above function as shown below:
Hence, the required probability is
Multiply the change per hour by the number of hours:
3.5 degrees per hour x 2.5 hours = 8.75
Since the temperature dropped, the change would be a negative value.
The change was -8.75 ( -8 3/4) degrees.

Answer:
160
Step-by-step explanation:
The measure of an arc is always twice the degree of the corresponding angle inside the circle. For example, the measure of arc DC is just double the measure of angle DOC; angle DOC is 44 degrees, so arc DC must be 88 degrees.
Angle COB is 80 degrees, so arc CB is 160 degrees.
The Correct answer to it is -14 - (-6) = - 8
