Answer:
The probability that an athlete chosen is either a football player or a basketball player is 56%.
Step-by-step explanation:
Let the athletes which are Football player be 'A'
Let the athletes which are Basket ball player be 'B'
Given:
Football players (A) = 13%
Basketball players (B) = 52%
Both football and basket ball players = 9%
We need to find probability that an athlete chosen is either a football player or a basketball player.
Solution:
The probability that athlete is a football player = 
The probability that athlete is a basketball player = 
The probability that athlete is both basket ball player and football player = 
We have to find the probability that an athlete chosen is either a football player or a basketball player 
.
Now we know that;
Hence The probability that an athlete chosen is either a football player or a basketball player is 56%.
A)6 b)4 c)2 d)0. You just have to replace X with given number.
Answer:
2
a) 6.37%
b) 6.25%
3
a) 0.60 %
b) 0.59 %
Step-by-step explanation:
2 )
a) With replacement
Probability of extracting a club is 13/52
Probability of extracting a spade is 13/51
13/52 * 13/51
= 6.37 %
b) Without replacement
13/52 * 13/52
= 6.25 %
3) With replacement
Probability of extracting a ace is 4/52
Probability of extracting a queen is 4/51
4/52 * 4/51
= 0.60 %
b) Without replacement
4/52 * 4/52
= 0.59 %
Answer:
3^2 x 3^10
Step-by-step explanation:
Answers: 1:B, 2:450
How-To:
Using the formula for area on the bottom of the can, (pi*r^2) you can then multiply by the amount of height missing, which is 4.
Since it was originally 10, you subtract 4 in order to get 6.
That's how to get 4.
Now, plug in pi*r^2 into a calculator (or if you must work it out, radius, r, is 10, so 10*10 is 100. 100*3.14159265 is 314.159265
Now multiply 314 by the height missing (4) to get approximately 1257.
Now for number 2.
It says it is dilated by a scale factor of 1:3 (from 1350). That means that it was made smaller, (that's what dilated means) by 3 for every 1. So take 1350 and divide it by 3 to get 450
