What is the probability that between 77 and 120 complaints are received in one week?
Answer:
0.6856
Step-by-step explanation:
[tex]\text{The missing part of the question states that we should Note: that N(108,20) model to } \\ \\ \text{ } \text{approximate the distribution of weekly complaints).]}[/tex]
Now; assuming X = no of complaints received in a week
Required:
To find P(77 < X < 120)
Using a Gaussian Normal Distribution ([tex]\mu =[/tex]108, [tex]\sigma[/tex] = 20)
Using Z scores:
[tex]Z = \dfrac{77-108}{20} \\\\ Z = -\dfrac{35}{20} \\ \\ Z -1.75[/tex]
As a result X = 77 for N(108,20) is approximately equal to to Z = -1.75 for N(0,1)
SO;
[tex]Z = \dfrac{120-108}{20} \\ \\ Z = \dfrac{12}{20}\\ \\ Z = 0.6[/tex]
Here; X = 77 for a N(108,20) is same to Z = 0.6 for N(0,1)
Now, to determine:
P(-1.75 < Z < 0.6) = P(Z < 0.6) - P( Z < - 1.75)
From the standard normal Z-table:
P(-1.75 < Z < 0.6) = 0.7257 - 0.0401
P(-1.75 < Z < 0.6) = 0.6856

A circle has a radius of 5 centimeters. What is the area?
Answer:
[tex]25\pi[/tex]
Step-by-step explanation:
The formula for the area of a circle is [tex]A=\pi r^{2}[/tex], r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however [tex]25\pi[/tex] is the exact answer.
The number of nails in a 5 lb box is normally distributed with a mean of 325 nails and a standard deviation of 15 nails
Suppose that 1200 different 5 lb boxes are in a warehouse.
About how many boxes contain more than 340 nails?
O 170
O 192
O 340
O 384
Answer: 192.. just took the test :)
Step-by-step explanation:
The number of boxes contains more than 340 nails will be 190. Option B is correct.
What is Z score?The number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured is known as the Z score.
Z score for the 340 nails is found as;
[tex]\rm Z-score= \frac{340-325}{15} \\\\ Z-score=1[/tex]
If the probability of the z score is grater than 1 is;
P(Z≥1)=1-P(Z≤1)
P(Z≥1)=1-0.8413
P(Z≥1)=0.1587
For the 1200 boxes with more than the 340 nails is 192.
Hence,option B is correct.

During the fall you charge $10 to go to a house and rake the leaves and an additional eight dollars for every hour that you rake the yard if you earned $42 how many hours did you spend raking the leaves
Answer:
4
Step-by-step explanation:
set up an equation:
let h be the number of hours you spent raking.
then, the cost would be 10 + 8 times the number of hours.
In equation form:
[tex]10 + 8h = 42[/tex]
solve:
[tex]10 + 8h = 42\\8h = 32\\h = 4[/tex]
So you worked for 4 hours
A perfect square is the product of any positive whole number used as a factor exactly two times. [Example: 49 is a perfect square because 7 × 7 = 49] … The positive whole number N, when multiplied by 150, is a perfect square.
Answer:
6
Step-by-step explanation:
The computation of the least possible whole number is shown below:
Here we need the factors of 150 i.e.
= 3 × 5 × 2 × 5
Here we can add to one box and the 5 to the other box
And, now if we can add 3 to one box and in the other we can add 2 so they cant be equal to each other
Now lets try 5 × 6 and 5
So, here The perfect square is 900
= 30 × 30
= 900
Hence, the number would be 6

Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, of all homeowners are insured against earthquake damage. Four homeowners are to be selected at random; let denote the number among the four who have earthquake insurance.
1. Find the probability distribution of X. [Hint: Let S denote a homeowner who has insurance and one who does not. Then one possible outcome is SFSS, with probability (.25)(.75)(.25)(.25) and associated X value 3. There are 15 other outcomes].
2. What is the most likely value for X?
3. What is the probability that at least two of the four selected have earthquake insurance?

Answer:
[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]
[tex]Mean = 1[/tex]
[tex]Pr = 0.2617[/tex]
Step-by-step explanation:
Given
[tex]n = 4[/tex]
[tex]p = 25\%[/tex]
Solving (a): The probability distribution of x
We have:
[tex]n = 4[/tex]
[tex]p = 25\%[/tex] [tex]= 0.25[/tex]
The probability of not having earthquake insurance (q) is:
[tex]q = 1 - p[/tex]
[tex]q = 1 - 0.25[/tex] [tex]= 0.75[/tex]
If x has insurance, then n - x do not.
The distribution follows a binomial pattern. So, the probability distribution is:
[tex]P(X = x) = ^nC_x * 0.25^x * 0.75^{n-x}[/tex]
Substitute 4 for n
[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]
Solving (b): The most likely value of x i.e. The mean
We have:
[tex]n = 4[/tex] and
[tex]p = 25\%[/tex] [tex]= 0.25[/tex]
[tex]Mean = np[/tex]
[tex]Mean = 4 * 0.25[/tex]
[tex]Mean = 1[/tex]
Solving (c): At least 2 of 4 selected have earthquake insurance.
This is calculated as
[tex]Pr = P(x = 2) + P(x = 3) + P(x = 4)[/tex]
[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]
[tex]P(X=2) = ^4C_2 * 0.25^2 * 0.75^{4-2}[/tex]
[tex]P(X=2) = 6 * 0.25^2 * 0.75^2 = 0.2109375[/tex]
[tex]P(X=3) = ^4C_3 * 0.25^3 * 0.75^{4-3}[/tex]
[tex]P(X=3) = 4 * 0.25^3 * 0.75 = 0.046875[/tex]
[tex]P(X=4) = ^4C_4 * 0.25^4 * 0.75^{4-4}[/tex]
[tex]P(X=4) = 1 * 0.25^4 * 1= 0.00390625[/tex]
So:
[tex]Pr = P(x = 2) + P(x = 3) + P(x = 4)[/tex]
[tex]Pr = 0.2109375 + 0.046875 + 0.00390625[/tex]
[tex]Pr = 0.26171875[/tex]
[tex]Pr = 0.2617[/tex] --- approximated

han want to buy a $30 ticket to a game, but the pre-oder tickets are sold out, he knowns there will be more tickets sold the day of the game, with a markup of 200% . how much should han expect to pay for the tickets if he buys it the dat of the game?
Answer: [tex]\$90[/tex]
Step-by-step explanation:
Given
The price of the ticket prior to match day is [tex]\$30[/tex]
It is stated that there is [tex]200\%[/tex] the markup on match day i.e.
The selling price of the ticket is
[tex]\Rightarrow S.P.=30+30\times 200\%\\\Rightarrow S.P.=30+30\times 2=30+60\\\Rightarrow S.P.=\$90[/tex]
So, han must expect to pay [tex]\$90[/tex] on that day
