It opens downwards so it looks like this “n”. That is because a in the formula is a negative number in this situation
Can we see an attachment of the problem?
Answer:
There is a 1/6 chance of rolling a certain number and 1/2 chance of getting a heads.
1/6 x 1/2 = 1/12 so C.
1 is the chance of getting the wanted number / 6 is all the numbers in total
When there are multiple chances you just multiply the fractions
Step-by-step explanation:
Answer:
(a)|MA|, |MB| and |MC|
(b) |BD|
(c) |BC|
Step-by-step explanation:
An adapted diagram of this question is attached. You can vary the labelled letters as required.
<u>Definition</u>
- A <u>radius </u>is a line drawn from the center of a circle to its circumference.
- A <u>segment </u>is a line that connects two points.
- A <u>diameter</u> is a chord which passes through the center of the circle.
- A <u>chord</u> is any line joining two points on the circles' circumference.
By these definitions:
(a)Segments that are radii of this circle.
We have: |MA|, |MB| and |MC|
(b)Segment that is a diameter of this circle.
|BD|
(c)A chord of this circle that is not a diameter.
|BC|
Answer:
C. 56.25π
Step-by-step explanation:
Circumference=15π=πd⇒d=15
Area=πr^2⇒r=d/2⇒r=7.5⇒π7.5^2=56.25π
