Total cubes:10
Yellow/10=6/10
6/10= 3/5
The probability of picking a yellow cube is 3/5. Hope this helps!
Answer:
2.3
Step-by-step explanation:
Using SOH CAH TOA, we can label CB as the alternate side seeing as it's opposite to the known angle 50 degrees. We know AB is the hypotenuse since it's the longest side. Therefore CA must be the alternate side.
Since we want to know BC, and we know information about AB, we need to use the use of the hypotenuse and the opposite. In SOH CAH TOA, SOH uses both of these.
Using S O H, we understand that sin(50) * 3 = CB
Therefore CB = 2.3 to 1 decimal place.
If you cut them into equal parts they will be 12.5 inches each piece.
Answer:
mean=14, variance=9.1
Step-by-step explanation:
for binomial distribution
n=number of outcomes
p=probability of succcess
q=probability of faliure
p+q=1
any probability given is always 'p'
mean=np
n=40
p=0.35
mean=40*0.35
mean=14
variance=npq
p+q=1
q=1-p
q=1-0.35
q=0.65
variance=40*0.35*0.65
variance=9.1
To subtract fractions, we need a common denominator, which would be 10. To do this, multiply 3/5 by 2
3 * 2 = 6
5 * 2 = 10
Now subtract
