Central angles are subtended by an arc between those two points, and the arc length is the central angle of a circle of radius one. The central angle is also known as the arcs angular distance.
Answer:
The probability of the occurring the event is 0.01632 approximately
Step-by-step explanation:
Consider the provided information.
We have selected 5 red candies and no green ones. Let's say there were 6 green and 7 red candies in the bowl before discovery.
Therefore the total number of candies are 6+7=13
I have selected 5 red candies out of 7 red candies.
Thus, the probability of selecting 5 red candies and no green candies is:
Hence, the probability of the occurring the event is 0.01632 approximately
Answer:
The true statement about the results of the survey is:
- <u>48% of students preferred the seacoast</u>.
Step-by-step explanation:
To identify if the D option is right, you only must use a simple rule of three, where you use the total of the members surveyed in the club (150), and the number of members that preferred the seacoast (72), by the last the operation must confirm that this value (72) is equal to the 48% (how says in the D option). First, you must establish the rule of three:
- 150 = 100 (100% of surveyed really, but is easier to understand in this form)
- 72 = X
And operate:
- X= (72 * 100) / 150
- X = 48 (this means the 48%)
How you can see, <em>the value obtained in the simple rule of three is exactly </em><em>the percentage of the D option, for this reason, this is the true statement</em>.
Answer:
A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school? and "how old are you?" are statistical questions.
