EQUATION OF A CIRCLE = (x-h)² + (y-k)² =r²
Since the center of the cercle is in O, then h=5 & k=-2
(x-5)² + (y+2² =9
Answer:
the answer for this question is 18
Answer:The probability of the complement of an event is one minus the probability of the event. Since the sum of probabilities of all possible events equals 1, the probability that event A will not occur is equal to 1 minus the probability that event A will occur.
Step-by-step explanation:Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.

Answer:
The type of sampling method used is Stratified Sampling: Stratified Sampling is where the population has a number of distinct categories (different age groups in Billy's case). Here, the sampling frame can be organised into separate categories( age groups) which is called 'strata'. Each stratum is then sampled as an independent sub-population out of which individual elements can be randomly selected. In this case, each element in a group has a chance of being selected. With Stratified sampling, the best survey result occurs when elements within the strata are internally homogeneous ( in this case, the customers from each age group are selected).
