Step-by-step explanation:
Answer:
Standard deviation = 0.547
Step-by-step explanation:
Given the data
$5 for spade
$10 for any club
$20 for an ace club
Lets assume Probability of getting these cards to be
0.5, 0.20 and 0.30
Therefore, mean would be
Summation (PX) = 5×0.5 + 10×0.2 +20×0.3
Summation (PX)/n= 10.5/35 = 0.3
Standard deviation = √0.3
Standard deviation = 0.547
Answer:
The answer is 7 x + 3 =24 because its a problem solving
Answer:
The pythagorean theorem is a^2 + b^2 = c^2
Step-by-step explanation:
Not sure what you're asking! Sorry! :)
The smaller number is 'x' .
The larger number is (x+ 20)
Their sum is [ x + (x + 20 ]
2x + 20 = 44
Subtract 20 from each side:
2x = 24
Divide each side by 2 :
x = <u>12</u>
and
x + 20 = <u>32</u>
