Answer:
30.96
Step-by-step explanation:
First you must find the diameter of the circle which is 12
Then you must use the formula A=πr²
So it should be = to A = 3.14 ×144 which is 30.96
The best choice from the ones viewable in your picture is B) 1.
With that being said, 1 is used to indicate a perfect fit, which there is not one for this plot.
However, 0 would not be correct either, as 0 implies no correlation. We can see from the graph that there is a correlation.
-0.95 would not work either, as the line appears to trend upward; a negative correlation coefficient indicates it trends down.
One dice has 6 sides and two dice will give us 12 sides with 36 possibilities
it will be 9/36=.25
so it will have 25% chance of the two dice to have a sum of 9
Answer:
option d
Step-by-step explanation:
Given that a coin is tossed 5 times. Assuming it is a fair coin, head and tail are equally likely.
If we toss 5 times, the number of heads can be either 0 or 1 or 2...5.
Number of outcomes that have 2 heads
=out of 5, two heads and three tails
=5C2
=5(4)/2
=10
So answeris 10
Option d is right answer
