Answer: the probability that a randomly selected value is greater than 161.9 is 0.977
Step-by-step explanation:
Since the distribution of values is normal, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = randomly selected values.
µ = mean value
σ = standard deviation
From the information given,
µ = 165.6
σ = 18.7
We want to find the probability that a randomly selected value is greater than 161.9.. It is expressed as
P(x > 161.9) = 1 - P(x ≤ 161.9)
For x = 161.9
z = (161.9 - 165.6)/18.7 = - 0.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.023
P(x > 161.9) = 1 - 0.023 = 0.977
Answer:
No, it is not okay to conduct the simulation this way.
Step-by-step explanation:
In statistics, simulation refers to a technique that is employed to model random events so that the results obtained from using the simulation is significantly similar to the results obtained from observing the real-world.
Researchers are therefore able to understand the real world when they observe the simulated outcomes.
From the description above, it can be seen that simulation is about studying random events. Therefore, a sample of the population that will be used in the simulation must be selected through a random sampling.
Random sampling refers to the sampling method that gives equal opportunity of being selected to each member of the population. This makes the sample selected through random sampling technique to be an unbiased representation of the total population.
As a result, making up 31 numbers between 1 and 365 by the student is not a random sampling, because his method may favor some numbers over others. It is therefore a defective method of carrying out simulation.
Therefore, the it is not okay to conduct the simulation this way.
I wish you the best.
Answer:
-i(6/7)√2
Step-by-step explanation:
42.5p=c
You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.
M is representing the amount of money each person paid
(M)10=425
M=425/10
M=42.50 <- since it’s about money
Each person paid $42.50
The cost for 15 people is $637.50.
42.5p=c
42.5(15)=637.5
Hey There!
In order to simplify this expression, you would have to combine the like terms.
9+1 = 10
Nothing else could be done, therefore the answer would be.
7v + 10
Hope this helped!
