When the equation contains variable adds as out and the final sentence as true it contains the infinite solution
<u>Step-by-step explanation:</u>
- When you solve an equation and it ends up with a true statement in that case solution for that particular equation will be mostly dealing with all the real numbers and stuff.
- For example, If your last steps in the equation complete in this step as 10X=10X.
- Here X denotes the value and x can take an infinite number of values.
Given Information:
Probability of success = p = 75 %
Total number of students = n = 1200
Required Information:
Standard deviation = σ = ?
Answer:
Standard deviation = 15
Step-by-step explanation:
In a binomial distribution, the probability of success does not change from trial to trial and the probability of events in not dependent on each other. Also the number of trials are fixed. So this problem can be modeled using binomial distribution.
The mean of the number of students who choose to enroll is given by
μ = n*p = 1200*0.75
μ = 900
The standard deviation of the number of students who choose to enroll is given by
σ = √np(1 - p)
σ = √1200*0.75(1 - 0.75)
σ = 15
Therefore, the standard deviation of the number of students who choose to enroll is 15.
Answer:
4 ft
Step-by-step explanation:
We know that 1 ft = 12 inches
48 inches * 1 ft/ 12 inches = 4 ft
12/15
Divide 12 by 15 and then you should get 0.8
0.8 is obviously equal to 8/10ths or 80%
Hope this helps :)
Answer:
36
Step-by-step explanation:
Let the total number of cotton candy = A
Number of blue cotton candy = 27 cones
Percentage of blue cotton candy = 75%
Therefore, the total number of cotton candy is calculated as:
27/A × 100 = 75%
2700/A = 75
Cross Multiply
75A = 2700
A = 2700/75
A = 36
Therefore, the amount of total cotton candy that we have is 36.
