The number of customers that come to a certain clothing store each day follows a normal distribution. The mean number of customers is 428, and the standard deviation is 32. What is the probability that more than 524 customers will come to the store on a given day?
A.
0.15%
B.
0.3%
C.
2.5%
D.
5%
Answer: the true answer is A
Step-by-step explanation:
Good luck, give Brainliest
Using the normal distribution, it is found that the probability that more than 524 customers will come to the store on a given day is given by:
A. 0.15%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 428, \sigma = 32[/tex].
The probability that more than 524 customers will come to the store on a given day is one subtracted by the p-value of Z when X = 524, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{524 - 428}{32}[/tex]
Z = 3
Z = 3 has a p-value of 0.9985.
1 - 0.9985 = 0.0015 = 0.15%.
Hence option A is correct.

Answer:
A. W
Step-by-step explanation:
The table in which each x-value is related to exactly one y-value is the table that represents a function.
Form the tables given, in table W, every x-value (input) has exactly one y-value (output) that is related to it.
The correct table that represents a function is table W
Functions and TablesFor a table of values to be a function, the input values also known as the domain of the function must NOT have a repeated values.
All values of the domain must have a unique values in the codomain for a table of values to be a function. From the given table, you can see that table X, Y and z all have repeated values in the domain column. This shows that these tables do not represent a functionHence the correct table that represents a function is table W

Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
infinite solutions
Step-by-step explanation:
you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.
-7(y= 1.5x - 6) which equals the equation below
-7y= -10.5x-42 then combine the other equation
7y=10.5x+42 and that equals

Answer:
551.8 feet
Step-by-step explanation:
We are given
Adjacent = 1300 feet
Opposite = x
Angle = 23°
We solve using the trigonometric function Tangent
tan θ = Opposite/Adjacent
tan 23 = x/1300 feet
Cross Multiply
x = tan 23 × 1300 feet
x = 551.81726107 feet
Approximately = 551.8 feet
The Length of the building = 551.8 feet
