Answer:
D.) 0.9990
Step-by-step explanation:
Given :
Number of questions = 10
True or False questions ; probability of success, p = 1/2 = 0.5
Using binomial distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability of getting atleast one correct answer :
P(x ≥ 1) = p(1) + p(2) +... P(x = 10)
Using a binomial probability calculator :
P(x ≥ 1) = 0.9990
To find out how many brothers they have, they need to multiply 4×1= 4
So there are 4 brothers.
I hope this helped :)
If by description you mean simplification then: 84x/28
Based on the capacity of the container and the capacity currently being used, the amount of water in the container is <u>3/8 gallons. </u>
The container is capable of holding 1/2 gallons of water.
If it is holding 3/4 of that 1/2 gallons, the amount of water it would be holding is:
<em>= Capacity of container x Percentage full </em>
= 1/2 x 3/4
= 3/8 gallons of water
In conclusion, the container is currently holding 3/8 gallons of water.

Answer:
This is a ratio table,so therefore there is always a pattern.
Step-by-step explanation:
In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is <u>not</u> even,or the numbers are <u>not</u> even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.
