There's one piece of information missing from the question, so
in order to completely calculate the answer, we must assume the
missing number.
We have no information that helps us calculate the probability
that you will eat the first jelly bean. So we'll have to assume that
you will definitely eat it, no matter what color it is. The probability is 1 .
-- You start out with (2 + 4 + 8 + 6) = 20 jelly beans in the package.
8 of them are purple.
-- If you close your eyes and pull one out of the package, then the
probability that it will be purple is
8 / 20 .
-- You definitely eat it. The probability of this event is 1 .
-- Now there are 19 jelly beans left in the package.
6 of them are blue.
-- The probability of picking a blue one out of the package without peaking is
6 / 19 .
-- The probability of all three of these events happening is
(8/20) · (1) · (6/19)
= (8 · 1 · 6) / (20 ·19)
= 48 / 380
= 12/95 = 0.1263... = 12.63...% (rounded)
Answer:
Points scored in a basketball game vary directly with shots taken.
This means that this question can be solved
by proportions, using a rule of three.
How many would she have scored if she takes 60 shots?
Using a rule of three:
50 points - 40 shots
x points - 60 shots
Applying cross multiplication:
4x = 50 × 60
Divide from both sides
x = 50 × 1.25 = 75
Answer is 75
Step-by-step explanation:
Here is a easier explanation if you didn't understand clearly:
It asked for how many 60 shots would score.
You would look at the first time he scored which is 50 and took 40 shots. Divide them
50 ÷ 40 = 1.25 or 1.5
So now you know each point scores 1.25 or 1.5
Now you multiply 1.25 or 1.5 with how many shots to see how much was scored and in this case 60 shots.
60 × 1.25 or 60 × 1.5
& They both end up equaling just the same, 75.
Hope it made sense :)
Answer:
20-gon
Step-by-step explanation:
First we start with the formula to find what the sum of angles will be if we know the number of sides.
S=(n-2)*180 where S is the sum of angles and n is the number of sides.
Normally you'd plug in n to find S, but you can do the opposite too.
3240=(n-2)*180
Let me know if you need help working it from here.
