Step-by-step explanation:
We have an elevator with 5 men and 7 women. We want to find the probability that 3 women and one man will come down from the elevator.
To calculate this probability we can use combinations.
The formula of combinations is:
[tex]nCr = \frac{n!}{r!(n-r)!}[/tex]
Where you can choose between n people and choose r from them.
First we calculate all the possible results of the experiment.
That is, the amount of ways to select 4 people from a group of 12 people.
[tex]12C4 = \frac{12!}{4!(12-4)!} = 495[/tex]
There are 495 results.
Now we calculate the possible number of ways to obtain the desired result, that is 3 women and one man.
The possible combinations of selecting 3 women from a group of 7 is.
[tex]7C3 = \frac{7!}{3!(7-3)!} = 35[/tex].
The possible combinations of selecting 1 a man from a group of 5 is
[tex]5C1 = \frac{5!}{1!(5-1)!} = 5[/tex]
Then the number of ways in which 3 women and one man can be obtained is:
[tex]7C3 * 5C1 = 35 * 5 = 175[/tex]
Finally the probability is:
P = Number of ways to obtain the desired result ÷ possible number of results
[tex]P = \frac{7C3 * 5C1}{12C4}\\\\P = \frac{175}{495}[/tex]
[tex]P = 0.354[/tex]

A cabin cruiser travels 48 miles upstream (against the current) and 48 miles downstream (with the current). The speed of the current is 4 miles per hour. Find the total time traveled if the cabin cruiser travels at 12 miles per hour in still water.
The answer is:
The total time traveled is equal to 9 hours.
Why?To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.
So, we need to write two equations:
Let be "x" the speed of the cabin cruiser (12 mph in still water)
Let be "y" the speed of the current (4 mph).
Then,
For the travel against the current (upstream), we have:
[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]
For the travel with the current (downstream), we have:
[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]
Also, we know that the speed of the cruise traveling in still water is equal to 12mph.
So,
Calculating the time traveled upstream, we have:
[tex](x-4mph)*t_{upstream}=48miles[/tex]
[tex](12mph-4mph)*t_{upstream}=48miles[/tex]
[tex](8mph)*t_{upstream}=48miles[/tex]
[tex]t_{upstream}=\frac{48miles}{8mph}=6hours[/tex]
Calculating the time traveled downstream, we have:
[tex](x+4mph)*t_{downstream}=48miles[/tex]
[tex](12mph+4mph)*t_{downstream}=48miles[/tex]
[tex](16mph)*t_{downstream}=48miles[/tex]
[tex]t_{downstream}=\frac{48miles}{16mph}=3hours[/tex]
Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:
[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]
Hence, we have that the total time traveled is equal to 9 hours.
Have a nice day!

How to find the median
To find the median of a data set, you need to arrange the data in ascending order (from smallest to largest) and then find the middle value.
In the stem and leaf plot, we have to express the numbers as follows
50 53 65 64 75 77 78 82 84 85 86 87 87 90 91 92 93 94 96 97 99
The data set is 21. The meidan is the number in the middle. This will be the 11 position in this case
The number in the 11th positon here is 86
Match each exponential function to the description of its percent rate of change. 22% growth 12% decay 2% decay 20% growth 20% decay 22% decay 2% growth 12% growth. f(x) = 44(0.88)^x, f(x) = 124(1.22)^x, f(x) = 22(0.8)^x, f(x) = 42(1.12)^x
The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.
Then we have the following:
1) 22% grow
y = a( 1 + 22%/100 )^x = a(1.22)^x
So the solution is: 124(1.22)^x
2) 12% decay
y = a( 1 - 12%/100 )^x = a(0.88)^x
So the solution is: y = f(x) = 44(0.88)^x
3) 20% decay
y = a( 1 - 20%/100 )^x = a(0.8)^x
So the solution is: f(x) = 22(0.8)
4) 12% Groth
y = a( 1 + 12%/100 )^x = a(1.12)^x
So the solution is: f(x) = 42(1.12)^x
Final answer:
Each exponential function is matched to its percent rate of change by the base of the exponent; a base greater than 1 indicates growth, while a base less than 1 indicates decay.
Explanation:
The question involves matching each exponential function to its corresponding percent rate of change, which indicates whether there is exponential growth or decay. The base of the exponent in the function represents the rate of change: a base greater than 1 indicates growth, while a base less than 1 indicates decay. Here's how we match the given functions:
f(x) = 44[tex](0.88)^x[/tex] corresponds to 12% decay because 0.88 represents a decay rate of 12%.
f(x) = 124[tex](1.22)^x[/tex] corresponds to 22% growth because 1.22 represents a growth rate of 22%.
f(x) = 22[tex](0.8)^x[/tex] corresponds to 20% decay because 0.8 represents a decay rate of 20%.
f(x) = 42[tex](1.12)^x[/tex] corresponds to 12% growth because 1.12 represents a growth rate of 12%.
By recognizing the base of the exponential function, we can determine the percentage rate of change and appropriately classify each function as either exponential growth or decay.

a quadradic polynomial has a degree of 2 true or false
Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:
[tex]f(x)=ax^2+bx+c[/tex]
You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial [tex]f(x)=ax^2+bx+c[/tex] that the highest exponent is "2", which is the exponent of the term [tex]ax^2[/tex]
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.

What type of angle is
Answer:
I'm really sorry I can't tell you the answer because you have to measure the angle by yourself using a protractor. But I gave you information about types of angles if you got the degree of angles ( e.g 90 degrees). Hope it helped.
Step-by-step explanation:
acute angle-an angle between 0 and 90 degrees
right angle-an 90 degree angle
obtuse angle-an angle between 90 and 180 degrees
straight angle-a 180 degree angle
For this case we have that by definition:
Sharp angle: It is less than 90 degrees.
Flat angle: Measures 180 degrees.
Obtuse angle: Measures more than 90 degrees
The figure shows a pair of angles, each measuring 77 degrees. Now they enter the definition of acute angles.
To find the angle CEB we subtract:
[tex]180-77 = 103[/tex] degrees
This is the same measure of angle AED.
These would be obtuse angles.
Answer:
Sharp angles (77 degrees)
Obtuse angles (103 degrees)
In a group of students, 18 read marketing, 19 read economics, 16read finance, 6 read marketing only, 9 read economics only, 5 read marketing and economics only, and 2 read economic and finance only... find out
1) how many read all three subjects?
2) how many read finance only?
3) how many read marketing and finance only?
4) how many students are there altogether?
Answer:1)3
2)7
3)4
4)36
Final answer:
1. The number of students reading all three subjects is 3.
2. Those reading finance only is 7.
3. Those who read marketing and finance only is 4.
4. In total, there are 36 students.
Explanation:
To solve this Venn diagram problem involving students reading different subjects, let's take a methodical approach.
First, we know that 6 students read only marketing, and 9 read only economics.5 read both marketing and economics but not finance. This is found by subtracting those who read both from the total only marketing and economics readers.Next, 2 read economics and finance, but not marketing.The number of students that read all three subjects is found by taking the intersection of all three subjects and subtracting the sum of the intersections of two, which is given as 18 (for marketing) + 19 (for economics) + 16 (for finance) - 6 (marketing only) - 9 (economics only) - 2 (economics and finance only) - 5 (marketing and economics only), subtracting the students counted twice. The total number of students reading only one subject is 17 (6 marketing only + 9 economics only + 2 finance only).For the students reading all three, we have the total number of students minus the number of students reading only one or two subjects giving us 3 students reading all three.Those who read finance only can be calculated by taking the total number of finance readers (16) and subtracting those who read finance with other subjects (5 marketing and economics, 2 economics and finance, 3 all subjects), which gives us 16 - 3 - 2 - 5 = 7.The number of students who read marketing and finance only is found by subtracting those who read all three (3) from those who read both marketing and finance (8), this is, 8 (from finance total) - 3 (all subjects) - 1 (finance and economics only) = 4.To find out how many students there are altogether, we sum all the distinct category readers including those who read all three subjects once. This gives us 6 (marketing only) + 9 (economics only) + 2 (finance only) + 5 (marketing and economics) + 2 (economics and finance) + 4 (marketing and finance) + 3 (all three subjects) = 31. However, since there are 36 students, we conclude that there are 5 more students who do not fit into our calculated categories.At a pizzeria one day, 15% of the pizzas sold were topped with mushrooms.If 12 pizzas were topped with mushrooms, what was the toal number of pizzas sold that day?

for the graphed exponential equation calculate the average rate of change from x=-4 to x=1
-1/3
-5/8
-4/5
-7/8
Answer:
- [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here [ a, b ] = [ - 4, 1 ]
f(b) = f(1) = - 4 ← value from graph
f(a) = f(- 4) = 0 ← value from graph
Hence
average rate of change = [tex]\frac{-4-0}{1-(-4)}[/tex] = - [tex]\frac{4}{5}[/tex]
The average rate of change of a function is -4/5 from x=-4 to x=1 function is decreasing.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function shown in the picture.
f(-4) = 0
f(1) = -4
Average rate of change of a function = (-4-0)/(1-(-4))
= -4/5
Thus, the average rate of change of a function is -4/5 from x=-4 to x=1 function is decreasing.

To ensure an excellent bond when brazing, the clearance gap between pipe and fitting must be _______ inches.
Step-by-step Answer:
Gap must be a maximum of 0.005 inches, and uniform all around. Round out with a sizing tool if necessary.
When brazing, the clearance gap between pipe and fitting should be between 0.002 and 0.006 inches.
This clearance gap is important to allow the brazing material to flow via capillary action and to create a strong, sealed joint. The exact clearance can vary depending on the materials and the application, but staying within this range is a good practice.
For brazing larger diameter pipes and fittings, a slightly larger gap may be acceptable, but generally it is best to maintain the smallest gap that will still allow for proper capillary action of the filler metal.
what is the mass in slugs of a body weighing 500 ib?
W=500lb
m=?
W=mg(m=W÷g)
500=m×10
500÷10=m
50=m
In the English Engineering system, the unit slug is used to measure mass. The mass of an object in slugs can be calculated by dividing its weight in pounds (lb) by the acceleration due to gravity (32.2 [tex]ft/s^2[/tex]). Therefore, a body weighing 500 lb would have a mass of about 15.53 slugs.
Explanation:In physics, the unit slug is used in the English Engineering system where force is expressed in pounds (lb). The relationship between slug and lb is tied to the acceleration due to gravity on Earth which is approximately 32.2 [tex]ft/s^2[/tex]. To convert the weight of an object in lb to its mass in slugs you divide the weight by the acceleration due to gravity.
Thus, if an object weighs 500 lb, its mass in slugs can be found by dividing 500 lb by 32.2 [tex]ft/s^2[/tex]. So, the equation is:
Mass = 500 lb / 32.2 [tex]ft/s^2[/tex] = 15.53 slugs
