<h3>Answer: 36%</h3>
============================================
Explanation:
There are 20 blue cards out of 10+20+25 = 55 cards total.
Divide the 20 over 55 to get
20/55 = 0.363636...
where the "36"s go on forever
So 20/55 = 0.3636 approximately
Move the decimal point over 2 spots to go from 0.3637 to 36.37%
Then round to the nearest percent: 36.37% ---> 36%
The probability of getting a blue card is approximately 36%
Answer:
I believe the answer is B
Step-by-step explanation:
The answer is b, because it is linear and x and y have a proportional relationship with x increasing by 2 and y increasing by 4. So the slope is 2/4 or 1/2 making it a proportional relationship.
Answer:
69.77 % population increased from year 1 to year 5
Step-by-step explanation:
Population of year 1 = 2150
Population of year 2 = 3650
increase in population = 3650-2150 = 1500
Percentage increase = ( increased/intial) x 100
= (1500/2150) x 100
= 69.77
Answer:
Step-by-step explanation:
Given that the number of children in a household has a binomial distribution with parameters n-8 and p-50%
As per binomial definition we have
=
a) P(x=3 or 7) = P(3)+P(7) = 0.2188+0.0313=0.2501
b) P(X≤5)=0.8555
c) P(X≥3)=0.8555
d) P(x<7) =0.9648
