out of 100 people which are either tall or fat or both, 62 are tall, and 55 are fat. if i select one random person out of the 100 what is the probability, he is both tall and fat?
The probability a selected person is both tall and fat is 0.341
How to determine the probability?From the question, the given parameters are
People = 100
Fat = 55
Tall = 62
So, the individual probabilities are
P(Fat) = 55/100
P(Tall) = 62/100
Evaluate
P(Fat) = 0.55
P(Tall) = 0.62
The probability a person is both tall and fat is
P(Fat and Tall) = P(Fat) * P(Tall)
So, we have
P(Fat and Tall) = 0.55 * 0.62
Evaluate
P(Fat and Tall) = 0.341
Hence, the probability is 0.341

a gas grill originally priced at 399 is on sale for 30% off
what is the sales price of the grill?
sales tax is 8.375% find the price you will pay (including tax)
Answer:
$302.69
Step-by-step explanation:
399 x 30% = 119.7 # finding how much you save
399 - 119.7 = 279.3 # how much the item costs with the sale
279.3 x 8.375 = 23.39 # the sales tax for the discounted item
297.3 + 23.39 = 302.69 # adding sales tax to the discounted item
I think this is right. I was never that great at sales tax and discount.
7. |4n+ 2|= 34 solve for “N”
By solving |4n+2|=34 solve for N we get 8 .
What is N factor?
The factorial of a non-negative integer n, denoted by n!, is the product of all positive of integers less than or equal to n. The factorial of n also equals to the product of n with the next smaller factorial: For example, These are value of 0! is 1, according to the convention for an empty of product.
Sol-|4n+2|=34
Split into two equations
4n+2 = 34 or 4n+2=-34
4n+2 =34
Rearrange variable to the left side of the equation
4n =34-2
Calculate the sum or difference
4n=32
Devide both side of the equation by the coefficient of variable
n=32/4
Cross out the common factor
n=8
When n=8
LHS = |4×8+2|=34

The operations which must be part of the inverse function g(x) are:
Add 3Divide by 2.What is an inverse function?An inverse function can be defined as a type of function that is obtained by reversing or undoing a mathematical operation in a given function (f(x)).
In Mathematics, a given function (f(x)) and its inverse function has the following property f⁻¹(f(x)) = x.
Generally speaking, the inverse of multiplication is division while addition is the inverse of subtraction. In this context, we can reasonably and logically deduce that a "division by 2," followed by an "addition of 3" to the function f(x) are the operations that must be part of the inverse function g(x).

printer a can print a 300 page document in 10 minutes. printer b can print a 400 page document in 8 minutes. Both printers were run until a total of 1000 pages were printed. How many pages did printer b print?
Answer:
625 pages
Step-by-step explanation:
Rate x time of the one printer + the rate x time of the second printer = 1000 pages
t= time
([tex]\frac{300}{10}[/tex] )t +( [tex]\frac{400}{8}[/tex]) t = 1000
30t + 50t = 1000
t(30 + 50) = 1000
80t = 1000 Divide both sides by 80
t = 12.5
It took 12.5 minutes to get this job done with both printers.
Look at printer b
[tex]\frac{400}{8}[/tex] (12.5) = pages

the variance inflation factor (vif) is another measure that can detect a high correlation between three or more predictor variables even if no pair of predictor variables has a particularly high correlation. what is the smallest possible value of vif? (absence of multicollinearity).
Variance inflation factor can have a value as low as one (absence of multicollinearity). A VIF number greater than 5 or 10 generally denotes collinearity that is problematic.
The variance of bj is not inflated at all if the VIF is 1, which indicates that there is no association between the jth predictor and the other predictor variables.
VIF equal to 1 signifies that there is no correlation between the variables. A VIF of 1 to 5 indicates a moderate correlation between the variables. Variables are highly linked when the VIF is greater than correlated2.
VIF = 1.0 if all independent variables are orthogonal to one another. VIF = infinity if there is perfect correlation.

a certain store has 3,000 employees working at its main location in a city and 100 employees working at a smaller location outside the city. the store manager will select a sample of 50 employees from all the employees to ask their opinions about extending store hours during the holidays. what is the advantage of selecting a stratified random sample, with location as strata, instead of a simple random sample? responses
The answer is the stratified sample assures that the opinions of employees from both locations will be represented..
The survey results will accurately reflect the opinions of both urban and rural employees if you choose this option. By soliciting feedback from employees in both regions, it will be possible to ensure that any policy based on the results of this survey not only represents the interests of urban employees, who make up the bulk of the workforce, but also those of rural employees.
Option B is untrue since a stratified sample will cost more to implement than a straightforward random sample and won't always result in financial savings.
Option C does not applicable because it is just a supposition without any supporting data.
Choice D is False, since a stratified sample in this situation produces results that are more typical of the store's employees from both locations than a random sample.

The probability that a randomly selected band member is a senior given that he or she plays the trumpet is 34.78%.
Probability is defined as the likeliness of an event to happen. It can be calculated by dividing the total desired outcomes by the total outcomes.
P = desired outcomes / total outcomes
Of the 108 band members, if 23 play the trumpet, and 8 are seniors who play the trumpet, then the probability that a randomly selected band member is a senior given that he or she plays the trumpet is 8 divided by 23.

What is the equation of the line that passes through the point (-6, 5) and has a
slope of - 3/2
Answer:
y = - [tex]\frac{3}{2}[/tex] x - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - [tex]\frac{3}{2}[/tex] , then
y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
to find c substitute (- 6, 5 ) into the partial equation
