Answer:
True
Step-by-step explanation:
Answer:
<em>Standard deviation for the number of people with the genetic mutation = 4.178</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given random sample size 'n' =600
proportion of the Population 'p'=3% or 0.03
Let 'X' be the random variable in binomial distribution
Mean of the binomial distribution
μ = n p
= 600 X 0.03
= 18
<em>Mean of the binomial distribution ' μ ' =18</em>
<em>Standard deviation of the binomial distribution</em>
<em> σ = </em>
<u><em>Conclusion:</em></u><em>-</em>
<em>Standard deviation for the number of people with the genetic mutation = 4.178</em>
Answer:
60
Step-by-step explanation:
0.7x=42
42/0.7=60
The total of 2 buckets of popcorn and 3 boxes of candy would be $23.25
To answer this question you need to form a set of simultaneous equations and solve them. We can do this by saying that a bucket of popcorn = P, and a box of candy = C. Then we can say:
4P + 6C = 46.50
P + C = 9.75
There are then two possible ways to solve; you can either say that C = 9.75 - P using the second equation and then substitute it into the first, or you can multiply the second equation by either 4 or 6 to cancel out P or C.
I’m going to multiply the second equation by 4:
4P + 4C = 39
Now we can subtract this for, the first equation:
4P + 6C = 46.50
4P + 4C = 39
2C = 7.50
C = 3.75
Now we can substitute this value of C into one of the equations to find P:
P + C = 9.75
P + 3.75 = 9.75
P = 6
And now to answer the question, you just multiply P by 2 and C by 3 and add them together, which gives you $23.25
I hope this helps! Let me know if you have any questions :)
