Final answer:
There is a family of normal probability distributions, each representing different populations or sets of data with varying mean and standard deviation values.
Explanation:
Yes, there is a family of normal probability distributions. The normal distribution is a continuous probability distribution that can take on different forms depending on the mean and standard deviation. The family of normal distributions is characterized by different mean and standard deviation values, which result in different shapes of the distribution curve.
For example, the standard normal distribution has a mean of 0 and a standard deviation of 1, and its curve is symmetrical around the mean. Other normal distributions may have different means and standard deviations, resulting in curves that are shifted or stretched.
Each normal distribution in the family represents a different population or set of data, and knowing the specific mean and standard deviation allows us to calculate probabilities and make statistical inferences.

Why would a bank charge a fee to noncustomers who use it’s ATM?
ANSWER: Charging a noncustomer helps pay for the cost of keeping the ATM running and supplied with cash. Customers of the bank already cover the ATM costs with regular fees or by allowing the bank to loan out their money.
Answer:
Bank charges fee to non customers while using ATM. ATM's frequently charge fees to users who are not account holders from that same bank whose ATM you are operating.
This fee goes towards the compensation for the costs associated with owning and operating the machine.
Same bank persons pay many types of fee yearly to their banks, so same bank ATM do not charge any fee.
When using other banks, your bank has to pay some interchange amount to that bank, this is also the reason why banks charge fee, basically they recoup the money that they will have to pay to other banks for interchange.

The use of the normal probability distribution as an approximation of the sampling distribution of p̄ is based on the condition that both np and n(1 – p) equal or exceed _____.
a. .05
b. 5
c. 15
d. 30
The use of the normal distribution as an approximation for the sampling distribution of[tex]\( \bar{p} \)[/tex] requires both [tex]\( np \)[/tex] and [tex]\( n(1 - p) \)[/tex] to be at least 5. So, the answer is (b) 5.
The normal approximation for the sampling distribution of [tex]\( \bar{p} \),[/tex] the sample proportion, relies on the conditions that both[tex]\( np \)[/tex] and [tex]\( n(1 - p) \)[/tex] are greater than or equal to 5. Here, [tex]\( n \)[/tex] represents the sample size, and [tex]\( p \)[/tex] is the probability of success in a binary outcome. These conditions ensure that the distribution of[tex]\( \bar{p} \)[/tex] is approximately normal, allowing for the application of statistical techniques based on the normal distribution. When[tex]\( np \)[/tex]and [tex]\( n(1 - p) \)[/tex]are both at least 5, the central limit theorem asserts that the distribution of [tex]\( \bar{p} \)[/tex] is sufficiently close to normal, facilitating the use of standard normal tables and z-scores for making probability calculations and inferences about the population proportion. This approximation is pivotal in hypothesis testing and confidence interval construction for proportions in statistical analyses.

Question Help Find the dimensions of the open rectangular box of maximum volume that can be made from a sheet of cardboard 45 in. by 24 in. by cutting congruent squares from the corners and folding up the sides. Then find the volume.
Answer:
The dimensions are [tex]35\times 14\times 5[/tex] and the volume is 2450 inches³.
Step-by-step explanation:
Given : The open rectangular box of maximum volume that can be made from a sheet of cardboard 45 in. by 24 in. by cutting congruent squares from the corners and folding up the sides.
To find : The dimensions and the volume of the open rectangular box ?
Solution :
Let the height be 'x'.
The length of the box is '45-2x'.
The breadth of the box is '24-2x'.
The volume of the box is [tex]V=L\times B\times H[/tex]
[tex]V=(45-2x)\times (24-2x)\times x[/tex]
[tex]V(x)=4x^3-138x^2+108x[/tex]
Derivate w.r.t x,
[tex]V'(x)=4(3x^2)-138(2x)+108[/tex]
[tex]V'(x)=12x^2-276x+108[/tex]
[tex]V'(x)=12(x^2-23x+90)[/tex]
The critical point when V'(x)=0
[tex]12(x^2-23x+90)=0[/tex]
[tex]x^2-23x+90=0[/tex]
[tex](x-18)(x-5)=0[/tex]
[tex]x=18,5[/tex]
18 is not possible we reject.
So, the height is 5 inches.
Derivate again w.r.t x,
[tex]V''(x)=24x-276[/tex]
[tex]V''(5)=24(5)-276[/tex]
[tex]V''(5)=120-276[/tex]
[tex]V''(5)=-156<0[/tex]
i.e. V(x) is maximum at x=5.
The dimensions are
Height = 5 inches
Length = 45-2(5)=35 inches
Breadth = 24-2(5)=14 inches.
The maximum volume is
[tex]V=35\times 14\times 5[/tex]
[tex]V=2450[/tex]
So, The dimensions are [tex]35\times 14\times 5[/tex] and the volume is 2450 inches³.

An orchard has 864 orange trees. The number of rows exceeds the number of trees per row by 5 . How many trees are there in each row?
Final answer:
Using a quadratic equation, we found that there are 24 orange trees in each row of the orchard.
Explanation:
To determine how many orange trees are there in each row, we will set up an equation based on the information provided. Let's let x represent the number of trees per row. According to the problem, the number of rows is x + 5. Since the total number of trees in the orchard is 864, we can create the following equation:
x * (x + 5) = 864
To solve this quadratic equation, we need to find the value of x that satisfies the equation:
First, expand the left side of the equation: [tex]x^{2}[/tex] + 5x.
Write the equation in standard form: [tex]x^{2}[/tex] + 5x - 864 = 0.
Factor the quadratic equation: (x + 36)(x - 24) = 0.
Solve for x: x = -36 or x = 24.
Since we cannot have a negative number of trees per row, we disregard x = -36.
Therefore, there are 24 trees in each row.

5m-1=4m+5 what is m.
The correct answer is 6. In other words, the value of m that satisfies the solving linear equation is m = 6.
In the given equation, we are asked to find the value of m. The equation states that the quantity 5m minus 1 is equal to the quantity 4m plus 5.
To solve this equation, we can use algebraic methods. The goal is to isolate the variable m on one side of the equation.
First, we combine like terms. By subtracting 4m from both sides of the equation, we eliminate the term with m on the right side. This results in the equation m - 1 = 5.
Next, we isolate the variable m by adding 1 to both sides of the equation. This cancels out the -1 term on the left side and gives us m = 6.
Therefore, the correct answer is 6. In other words, the value of m that satisfies the solving linear equation is m = 6.

Animals Balloons
15 200
24 164
33 128
How many balloons does Amira use for each balloon animal?
Answer:
4 balloons for each balloon animal.
Step-by-step explanation:
Amira sells balloon animals. The given table compares the number of balloon animals sold and the remaining number of balloons on a certain day.
Animals Balloons
15 200
24 164
33 128
When she sold 15 animals the leftover balloons were 200.
then she sold 24 animals the number of leftover balloons were 164.
The difference of the number of items = 24 - 15 = 9 more animals sold
The difference of the leftover balloons = 200 - 164 = 36 balloons used
Now the number of her sold animals was = 33
and the left over balloons = 128
The number of sale was increased by 24 to 33 = 33 - 24 = 9 more animals
and the leftover balloons now 164 to 128 = 164 - 128 = 36 used
Therefore, we can see each sale of 9 balloon animals she used 36 balloons.
so Amira used for each balloon animal = [tex]\frac{36}{9}[/tex]
= 4 balloons.
Amira used 4 balloons for each balloon animal.

A painter made the table below to show the amount of paint it takes to cover a certain amount of square feet. The amount of paint varies directly with the area of each wall.
Answer:
Option A.
Step-by-step explanation:
The table made by the painter shows the amount of paint required to cover a certain amount of area of the wall.
Amount of paint is directly proportional to the area covered
In other words Amount of paint (y) ∝ Area covered (x)
y ∝ x
As we know when proportionality sign is removed, a constant known as proportionality constant is multiplied with the variable.
So y = k(x) where k is the proportionality constant
Now from the table to cover the area of 64 square feet, 4 pints of paint is required.
Now from the formula
4 = 64x
x = [tex]\frac{4}{64}=\frac{1}{16}[/tex]
Now we have to calculate the amount of paint required to cover the area of 256 square feet.
y = [tex]\frac{1}{16}\times 256[/tex]
y = 16 pints
Therefore, 16 pints of the paint will be required to cover 256 square feet.
Option A is correct.
Answer:
Just Pick 16 Pints

A lender estimates the closing costs on a home loan of $50,000 as listed below.
Closing Cost
Charge
Loan origination
$200
Title insurance
$530
Attorney’s fees
$600
Appraisal
$265
Inspection
$575
Recording fees
$130
Escrow
$800
If the lender's good faith estimates are accurate, are they a reasonable amount for closing costs? Why or why not?
a.
Yes, because the lender esitmated 3.08% of the home loan in closing costs which falls between 3 - 5%.
b.
Yes, because the lender estimated 4.6% of the home loan in closing costs which does not fall between 3 - 5%.
c.
No, because the lender estimated 6.2% of the home loan in closing costs which does not fall between 3 - 5%.
d.
No, because the lender estimated 17.7% of the home loan in closing costs which does fall between
Answer:c.
No, because the lender estimated 6.2% of the home loan in closing costs which does not fall between 3 - 5%
Step-by-step explanation:
Summation of the cost of loan =200+530+600+265+575+130+800
=3100
Now percentage of the estimate=
(3100/50000)*100%
=6.2%
C- The lender should not consider them as reasonable amount of closing costs because the lender estimated 6.2% of the home loan in closing costs which does not fall between 3-5%.
The lender cannot be accepting these costs as this will lead to the lender incurring losses over a longer period after doing all the necessary calculations.
The lender has disbursed a home loan of $50000 on which he has estimated certain closing costs and are considered to be true and accurate. The costs are loan origination, title insurance, attorney's fees, appraisal, inspection, recording fees, escrow, etc.The amounts will add up as a summation of all the fees and charges as titles above are mentioned which will end up totaling to $3100[tex]200+530+600+265+575+130+800=3100[/tex]
The calculation of of costs in to the percentage of total home loan is calculated as dividing the cost with total loan amount which will be totaled as 6.2%.[tex]\frac{3100}{50000} *100= 6.2[/tex]
The costing of this home loan is way above the ideal range of 3-5% and is not worth disbursing and may be called back.Hence, the correct option is C that the amounts of $3100 are not a reasonable amount of closing costs because the lender estimated 6.2% of the home loan in closing costs which does not fall between the range of 3-5%.
