How many ways can 6 people be chosen and arranged in straight line if there are 8 people to choose from? a. 48.b. 720.c. 20, 160.d. 40, 320.
Answer:
C. 20,160Step-by-step explanation:
This question bothers on permutation since we are to select a some people out of a group of people and then arrange in a straight line. If r object are to be arranged in a straight line when selecting them from n pool of objects. This can be done in nPr number of ways.
nPr = n!/(n-r)!
Selection of 6 people out of 8 people can therefore be done in 8C6 number of ways.
8P6 = 8!/(8-6)!
8P6 = 8!/2!
8P6 = 8*7*6*5*4*3*2!/2!
8P6 = 8*7*6*5*4*3
8P6 = 56*360
8P6 = 20,160
Hence this can be done in 20,160 number of ways

I've been stuck on this for awhile
Answer:
B) $3.56
Step-by-step explanation:
The price of one egg: $1.69
The price of a slice of bacon: $1.49
The price of a glass of orange juice: $1.09
Sara buys 2 eggs, 1 slice of bacon, and 1 glass of orange juice.
(2 eggs x $1.69) + (1 bacon x $1.49) + (1 glass of oj x $1.09) =
($3.38) + ($1.49) + ($1.09) = $5.96
Next, add the total gotten with the sales tax.
Sales tax: $0.48
$5.96 + 0.48 = $6.44
Then, subtract the total from the $10 that she used to pay:
$10 - 6.44 = $3.56
B) $3.56 is your answer.
~
Answer:
3.56
Step-by-step explanation:
because first, you 1.69$ dollars 2 times since your ordering it 2 times which gets you 3.38 $ next you add 1.49$ dollars because that's what a slice of bacon cost, then add1.09 since that's what a cup of orange juice cost. Then add 0.48 cents because that's the sale tax, at the end when you add everything up you get 6.44$ then subtract that from 10.00, then you get your answer!

Y is the midpoint of XZ. X has coordinates (2, 8), and Y has coordinates (–3, 10). Find the coordinates of Z.
Answer:
The coordinates of Z is (-8,12)
Step-by-step explanation:[tex]\frac{2+x^{2} }{2}= -3 \\\frac{8+y^{2} }{2} = 10[/tex]
You multiply -3 by 2 to get -6 then multiply 10 by 2 to get 20
then you create the equations [tex]2+x^{2} =-6\\8+y^{2} =20[/tex] you subtract 2 by -6 and you get -8 (x coordinate) and you subtract 8 by 20 to get 12 (y coordinate)
To check your answer you use the Midpoint formula [tex](\frac{x^{1}+ x^{2} }{2} )(\frac{y^{1}+y^{2}}{2}) =M[/tex]
[tex]\frac{2+-8}{2} =\frac{-6}{2} = -3\\\frac{8+12}{2} =\frac{20}{2} =10[/tex] and you get your midpoint.

The heights of tomato plants are Normally distributed with About % of tomato plants have a height
a mean of 3.56 feet and a standard deviation of 0.25 feet.
between 2.98 feet and 3.48 feet. Round the percent to 2
About what percent of tomato plants have a height decimal places, if necessary
between 2.98 feet and 3.48 feet?
Use the z-table to answer the question.
Answer:
36.43
Step-by-step explanation:
In normal distribution(z) tomato plants have a height of less than 2.58 feet is 1.017%.
What is a normal distribution?The normal distribution is a "continuous probability distribution that its symmetrical around its mean with most values near the central peak".
According to the question,
The heights of tomato plants are Normally distributed.
Mean(μ) = 3.56
Standard deviation (σ) = 0.25
For a tomato plant that has a height of 2.98 feet
In order to find the Percentage of tomato plantof s have a height less than 2.98 feet
Standard Normal Distribution Formula,
z = (x-μ)/σ where X~(μ,σ).
( 2.98 - 3.56 ) / 0.25 =-0.58 / 0.25 = -2.32.
P ( x < 2.58 ) = P( z < -2.32 )
= 0.01017( Using standard Normal distribution table)
Find the percentage of tomato plants with have a height of fewer than 2.58 feet is
Multiply 0.01017 by 100
= 0.01017 x 100 %
= 1.017%
Hence, using Standard Normal distribution we find tomato plants have heights less than 2.58 feet is 1.017%

Find the distance between A (-2, 4) and B (-6, -7). Leave your answer in exact (radical) form
Answer:
The answer is
[tex]\sqrt{137} \: \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A (-2, 4) and B (-6, -7).
The distance between them is
[tex]d = \sqrt{ ({ - 2 + 6})^{2} + ({4 + 7})^{2} } \\ = \sqrt{ {4}^{2} + {11}^{2} } \\ = \sqrt{16 + 121} \\ = \sqrt{137} \: \: \: \: \: \: \: \: \: \: [/tex]
We have the final answer as

What is the area of the triangle?
(-6,3)
(-3,-5)
(-1,3)
Hey there! I'm happy to help!
To find the area of a triangle you multiply the base by the height.
We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.
To find the area of a triangle, you just multiply the base by the height then divide by 2.
5(8)=40
40/2=20
The area is 20 square units.

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except –3. Which of the following describes the domain of (g circle f) (x)?
Answer:
Domain of a function means the set of values of the variable for which the given function exists.
(g circle f) (x) means g{f(x)}.
g{f(x)} will exists for all the real values of x except x = 7 and that particular x for which f(x) = -3.
Hence the domain of g{f(x)} will be all real values except x = 7 and the x for which f(x) = -3

How would you answer this question?
Answer: Choice B
If you lower your rates by 6% you will increase the number of occupancies by 12%
========================================================
Explanation:
Price Elasticity of Demand is found by dividing the percent change of demand over the percent change in price
[tex]\text{Price Elasticity of Demand} = \frac{\% \text{ change in demand}}{\% \text{ change in price}}[/tex]
If the price drops 6% leads to a 12% increase in demand, then we get this elasticity
[tex]\text{Price Elasticity of Demand} = \frac{\% \text{ change in demand}}{\% \text{ change in price}}\\\\\text{Price Elasticity of Demand} = \frac{12\% \text{ increase in demand}}{6\% \text{ drop in price}}\\\\\text{Price Elasticity of Demand} = \frac{12\%}{-6\%}\\\\\text{Price Elasticity of Demand} = \frac{0.12}{-0.06}\\\\\text{Price Elasticity of Demand} = -2\\\\[/tex]
The absolute value of that result is 2. We work backwards going from 2 to see the relationship between the 12% and 6%.
-------------
Side notes:
Choice A is incorrect as a price elasticity of demand larger than 2 means we have elastic (rather than inelastic) demand. Choice C is incorrect because while raising rates does bring in more money in certain situations, there's a limit to how much the price goes up before people stop showing up. The prices can't go up forever. Also, the fact we have an elastic product means people are either forgoing this hotel or finding a substitute.Choice D is incorrect. Products with high demand elasticity usually have substitutes. Any slight change in the price leads people to seek cheaper options. Unless we're dealing with a small town there are usually multiple hotels to choose from.I roll a number cube twice. What is the probability of rolling a 3 twice?
