Dorothy Little purchased a mailing list of 2,000 names and addresses for her mail order business, but after scanning the list she doubts the authenticity of the list. She randomly selects five names from the list for validation. If 40% of the names on the list are non-authentic, and x is the number on non-authentic names in her sample, the expected (average) value of x is ______________.
a) 2.50
b) 2.00
c) 1.50
d) 1.25
e) 1.35
Answers
Answer:
b) 2.00
Step-by-step explanation:
For each name, there are only two possible outcomes. Either it is authentic, or it is not. The probability of a name being authentic is independent of any other name. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
She randomly selects five names from the list for validation.
This means that [tex]n = 5[/tex]
40% of the names on the list are non-authentic
This means that [tex]p = 0.4[/tex]
The expected (average) value of x is
[tex]E(X) = np = 5*0.4 = 2[/tex]

How would the expression x-9 be rewritten using Difference of Squares?
Answers
Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out

Answers:
Statistical questionNot a statistical questionStatistical question==========================================
Explanations:
The phrasing here is a bit vague, but I think your teacher means "your" in the sense that it is directed at whoever is taking the survey and not a specific single person. If it was directed at exactly one person, and one person only, then no statistics are needed. You can simply count the number of songs on the device and that's the end of that story. However, when it comes to multiple people, statistics is used to give an idea of how the population is overall. Recall that the sample is supposed to represent the population, assuming no biases are present. I'll assume that your teacher is aiming for the more broader definition of "your" and that's why this is a statistical question. Similar reasoning will apply for problem 3.Unlike problems 1 and 3, this is not a statistical question. Why not? Because we know exactly how many feet are in 1 yard, and that will not change no matter what happens. It's simply a definition we set up earlier, and have stuck to. Having it change won't help things. Statistical questions address variables in which not only are allowed to change, but do so randomly (according to some pattern). Here we have 3 feet to a yard and no statistics are needed to address this.Similar to problem 1. I'm assuming your teacher is asking a broader audience and not exactly one single specific person. In this case, the name of the favorite movie would be considered qualitative categorical data, and also considered nominal as well. We don't have ordinal data because movies cannot be ordered or ranked, as that is subjective. I'm not considering alphabetical order. We have a statistical question here for the broader audience because the variable "favorite movie" is allowed to change, and is subject to some degree of randomness. Hence the phrasing "random variable".Answer:
multiply the length value by 3
so its 3 foot

2y + 3y -3y -6(y + 2) = -y + 6
Answers
my apologies if it’s wrong
Answer:
Step-by-step explanation:
2y + 3y -6(y + 2) = -y + 6
Solving lik terms
5y - 6(y + 2) = - y + 6
5y - 6y - 12 = - y + 6
-y - 12 = - y + 6
Bringing like terms on one side
-12 - 6 = - y + y
-18 = y
A car bought for $22,959 depreciates at 12% annually. What is its value after 7 years?
Answers
Answer:
After 7 years the car will be worth $ 9,382.78.
Step-by-step explanation:
Given that a car bought for $ 22,959 depreciates at 12% annually, to determine what is its value after 7 years, the following calculation must be performed, using exponential expressions to determine the price decrease:
100 - 12 = 88
22,959 x 0.88 ^ 7 = X
22.959 x 0.4086 = X
9,382.78 = X
Therefore, after 7 years the car will be worth $ 9,382.78.

Find the 9th term of the geometric sequence 5, -25, 125, ...
Answers
9514 1404 393
Answer:
1,953,125
Step-by-step explanation:
The first term is a1 = 5; the common ratio is r = -25/5 = -5. The generic term is ...
an = a1×r^(n-1)
an = 5×(-5)^(n-1)
So, the 9th term is ...
a9 = 5×(-5)^(9-1) = 1,953,125
Ben in n years old chloe is twice as old as Ben Dan is 5 years younger than Ben

T = 4n - 5
Step-by-step explanation:

4n - 5 = T years
Health insurers are beginning to offer telemedicine services online that replace the common office visit. Wellpoint provides a video service that allows subscribers to connect with a physician online and receive prescribed treatments. Wellpoint claims that users of its LiveHealth Online service saved a significant amount of money on a typical visit. The data shown below ($), for a sample of 20 online doctor visits, are consistent with the savings per visit reported by Wellpoint.
90 34 41
106 83 53
54 49 38
75 48 97
94 74 71
80 95 99
51 80
Assuming the population is roughly symmetric, construct a 95% confidence interval for the mean savings for a televisit to the doctor as opposed to an office visit (to 2 decimals).
95% confidence interval: $ to $ per visit
