A) 26.7%
B) 40%
The probability of A is given by 4/6(2/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 red out of 5 remaining.
The probability of B is given by 4/6(3/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 blue out of 5 remaining.
Assuming they are all standardised numbers, from largest:
Number of fans attending a World Series baseball game (10,000+)
Value of a home computer (~800)
Number of buttons on a telephone (10)
Average number of cars that can fit in a home garage (2)
Answer:
The second fish was heavier by almost 2.5 pounds
Step-by-step explanation:
6 5/8 - 4 1/6 = 59/24 = 2 11/24 = 2.458
Standard deviation is simply the square root of the variance.
We need to get the square root of each variance to see whether its standard deviation is greater than its variance.
A. 0.25 ⇒ √0.25 = 0.50B. 1.75 ⇒ √1.75 = 1.32C. 2.5 ⇒ √2.5 = 1.58D. 1.5 ⇒ √1.5 = 1.22
Among the choices, only A. 0.25 has a standard deviation that is greater than the variance. The standard deviation is 0.50
