The sport of korfball is played by teams of eight players. Each team has fourmen and four women on it. Halliday High School has seven men and 11 women interested in playing korfball.In how many ways can they form a korfball team from their 18 interested students
Answer:
There are 11550 possible selections
Step-by-step explanation:
Given
[tex]Men = 7[/tex]
[tex]Women = 11[/tex]
Required
How many ways can 4 men and 4 women be selected
The keyword in the question is SELECTION and it means COMBINATION;
So, number of selection is:
[tex]Number = Men * Women[/tex]
[tex]Number = ^7C_4 * ^{11}C_4[/tex]
This gives
[tex]Number = \frac{7!}{(7-4)!4!} * \frac{11!}{(11-4)!4!}[/tex]
[tex]Number = \frac{7!}{3!4!} * \frac{11!}{7!4!}[/tex]
[tex]Number = \frac{7 * 6 * 5 * 4!}{3!4!} * \frac{11 * 10 * 9 * 8 * 7!}{7!4!}[/tex]
[tex]Number = \frac{7 * 6 * 5}{3!} * \frac{11 * 10 * 9 * 8}{4!}[/tex]
[tex]Number = \frac{7 * 6 * 5}{3 * 2 * 1} * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}[/tex]
[tex]Number = \frac{7 * 6 * 5}{6} * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}[/tex]
[tex]Number = 7 * 5 * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}[/tex]
[tex]Number = 7 * 5 * \frac{7920}{24}[/tex]
[tex]Number = 7 * 5 * 330[/tex]
[tex]Number = 11550[/tex]
Hence;
There are 11550 possible selections

4/4, 5/4, and 6/4 will come in the given sequence of the pattern.
What is the pattern?A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
The hint which is present in a given pattern hides in the pattern only.
For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.
Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.
Given the pattern,
1/4, 1/2, 3/4
Now if we look then we will get to know that if we add 1/4 consecutively then the next term will come.
For example
1/4 + 1/4 = 1/2
1/4 + 1/4 + 1/4 = 3/4
So,
The next three terms will be
4/4,5/4 and 6/4.
Hence "4/4, 5/4, and 6/4 will come in the given sequence of the pattern".

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y = 1 + sec(x), −π 3 ≤ x ≤ π 3 , y = 3; about y = 1
Using the washer method, the volume is given by the integral
[tex]\displaystyle\pi\int_{-\pi/3}^{\pi/3}\bigg((3-1)^2-((1+\sec x)-1)^2\bigg)\,\mathrm dx=2\pi\int_0^{\pi/3}(4-\sec^2x)\,\mathrm dx[/tex]
where 3 - 1 = 2 is the distance from y = 3 to the axis of revolution, and similarly (1 + sec(x)) - 1 = sec(x) is the distance from y = 1 + sec(x) to the axis. The integrand is symmetric about x = 0, so the integral "folds" in on itself, and the integral from -π/3 to π/3 is twice the integral from 0 to π/3.
So the volume is
[tex]\displaystyle2\pi\int_0^{\pi/3}(4-\sec^2x)\,\mathrm dx=2\pi(4x-\tan x)\bigg|_0^{\pi/3}=\boxed{\dfrac{8\pi^2}3-2\pi\sqrt3}[/tex]

A group incoming first-year students at Major University were surveyed in order to determine the factors that influenced their decisions to choose to attend Major U. The survey revealed the following information. 55 said "great football team" (F) 51 said "excellent party reputation" (P) 61 said "it was the only place that would accept me" (O) 9 said "great football team" but didn't say "excellent party reputation" and didn't say "it was the only place that would accept me" 26 said "it was the only place that would accept me" and "great football team" and "excellent party reputation" 31 said "excellent party reputation" and "great football team" 8 said only "excellent party reputation" 4 said none of the above reasons Required:a. How many said "it was the only place that would accept me" and "excellent party reputation"? b. How many said "great football team "or "it was the only place that would accept me"? c. How many said "great football team "but no "excellent party reputation"? d. How many were surveyed?
Answer:
Step-by-step explanation:
This is a problem of SETS.
Start by listing out important data:
1. Total that said F = 55
2. Total that said P = 51
3. Total that said O = 61
4. F only = 9
5. F ∩ P ∩ O = 26 [NOTE: If you were to draw a Venn Diagram, 26 would be in the innermost circle because it comprises all three categories]
6. F ∩ P = 31
7. P only = 8
8. Students that said none of the 3 reasons = 4
QUESTIONS
1. How many said O and P? In other words, find the intersect of O and P. Find O ∩ P
2. How many said either F or O? [Answer to be gotten using a venn diagram] Find F ∪ P which translates to "F union P"
3. How many said F without saying P? [Answer to be gotten from the venn diagram as well]
4. How many students in total were surveyed? [HINT: Remember to include the 4 students that had none of the three options]
A) 12 said "it was the only place that would accept me" and "excellent party reputation"; B) 17 said "great football team" or "it was the only place that would accept me"; C) 24 said "great football team" but no "excellent party reputation"; and D) 87 students were surveyed.
Given that a group incoming first-year students at Major University were surveyed in order to determine the factors that influenced their decisions to choose to attend Major U, and the survey revealed that 55 said "great football team" (F), 51 said " excellent party reputation "(P), 61 said" it was the only place that would accept me "(O), 9 said" great football team "but didn't say" excellent party reputation "and didn't say" it was the only place that would accept me ", 26 said" it was the only place that would accept me "and" great football team "and" excellent party reputation ", 31 said" excellent party reputation "and" great football team ", 8 said only "excellent party reputation", and 4 said none of the above reasons, to determine:
A) How many said "it was the only place that would accept me" and "excellent party reputation"?
B) How many said "great football team" or "it was the only place that would accept me"?
C) How many said "great football team" but no "excellent party reputation"?
D) How many were surveyed?
The following calculations must be performed:
F = 55 (F = 9 + FP = 5 + FO = 15 + FPO = 26) = 55 - (26 + 9) = 20 - (31 - 26) = 15 = 9 + 5 + 15 + 26 = 55 // / FO = 15 /// FP = 5 P = 51 (P = 8 + PF = 5 + PO = 12 + PFO = 26) = 51 - 8 - 5 - 26 = 12 /// PO = 12 O = 61 (O = 8 + OP = 12 + OF = 15 + OPF = 26) = 61 - 12 - 15 - 26 = O = 8 None = 4 4 + 9 + 8 + 8 + 5 + 12 + 15 + 26 = X 87 = X
Therefore, A) 12 said "it was the only place that would accept me" and "excellent party reputation"; B) 17 said "great football team" or "it was the only place that would accept me"; C) 24 said "great football team" but no "excellent party reputation"; and D) 87 students were surveyed.

What is the value of x in 3x-9
Answer:
x could be anything. you have to have a equation to solve for x.
Step-by-step explanation:
if you could generate energy by fusing the hydrogen in solution a, how much of the solution would you need to generate the electrical energy used daily in a certain home? energy released by fusion of hydrogen in 1 liter of solution A = 7.6*10^10 Electrical energy used daily in a certain family home = 3*10^4
Answer:
We know that:
Energy released by fusion of hydrogen in 1 liter of solution A = 7.6x10^10 J
Energy used daily in a certain family home = 3x10^4 J
(you did not write the units, so i suppose that are the same in both cases)
Then, if x is the number of liters of solution A used, the energy produced will be:
E(x) = x*7.6x10^10 J
And we want this equal to 3x10^4
then:
E(x) = x*7.6x10^10 J = 3x10^4 j
now we solve this for x.
x = (3x10^4 j)/(7.6x10^10 j) = 3.9x10^-7
Then you need to use 3.9x10^-7 L of solution a.

Answer:
A and B
Step-by-step explanation:
Quadratic Equations: f(x) = a(bx - h)² + k
Quadratic equations always have a degree of 2. That means that we will always have an x² term. Of the 4 choices, only A and B offer a term of x², making them a quadratic.
Answer:
Y = 5x - 3/2 + x^2
Y = x^2 + 5x - 2
Step-by-step explanation:
The function must contain x^2.
That is have a degree of 2.
one more than seven times the difference of a number and 4 is equivalent to twice the difference of the number and 1
Answer:
the number is 5
Step-by-step explanation:
We have to find the equation to solve the problem.
Let the number be x
lets write one more than seven times the difference of a number and 4 in mathematical form
1. Difference of number and 4 will be written as x - 4
now
2. seven times the difference of a number and 4 will be written as
7*( x - 4)
3. one more than seven times the difference of a number and 4 is expressed as
1 + 7*( x - 4)
_____________________________________________
1 + 7*( x - 4) is equal to twice the difference of the number and 1
4. difference of the number and 1 is x - 1
5. twice the difference of the number and 1 is 2*(x-1)
Thus,
1 + 7*( x - 4) = 2*(x-1)
=> 1 + 7x - 28 = 2x -2
=> 7x - 27 = 2x - 2
adding 27 both sides
=> 7x - 27 + 27 = 2x - 2 + 27
=> 7x = 2x + 25
subtracting 2x from both sides
7x -2x = 2x + 25 - 2x
=> 5x = 25
dividing both side by 5
5x/5 = 25/5
x = 5
Thus, the number is 5 answer

Answer:
x=1/10
Step-by-step explanation:
x^2=1/100
x=root(1/100)
x=1/10
Answer:
[tex]x = \frac{1}{10}[/tex]
Step-by-step explanation:
If x squared gets us [tex]\frac{1}{100}[/tex], then we can create the equation [tex]x^2 = \frac{1}{100}[/tex].
To solve for x, we find the square root of both sides.
[tex]\sqrt{x^2} = \sqrt{\frac{1}{100}}[/tex]
The square root of [tex]\frac{1}{100}[/tex] is [tex]\frac{1}{10}[/tex], since [tex]10\cdot10=100[/tex].
This means [tex]x = \frac{1}{10}[/tex].

A bicycle is traveling at 20 miles per hour.
How many feet will it cover in 25 seconds?
Round your answer to the nearest tenth of a foot.
Answer:
Distance= 73.333 feet
Step-by-step explanation:
Speed of the bicycle= 20 miles per hour
1 mile =
5280 feet
I hour= 3600 seconds
Speed in feet/seconds=( 20*5280)/(3600)
Speed in feet/second= 29.333 feet/s
Distance= speed*Time
Distance= 29.333*25
Distance= 73.333 feet
A 47-inch piece of steel is cut into three pieces so that the second piece is twice as
long as the first piece, and the third piece is two inches more than six times the
length of the first piece. Find the lengths of the pieces
2x
6x+2
First, find an equation that represents the total length of the piece of steel in terms of x by adding the three pieces together,
Answer:
first piece: 5 in second piece: 10 in third piece: 32 inStep-by-step explanation:
x - the length of the first piece
2x - twice the length of the first piece (the length of the second piece)
6x - six times the length of the first piece
two inches more:
6x+2 - the length of the third piece
first + second + third = 47 in {total length of the pieces of steel}
x + 2x + 6x + 2 = 47
9x + 2 = 47
9x = 45
x = 45:9
x = 5 in
first piece: 5 in
second piece: 2×5 = 10 in
third piece: 6×5 + 2 = 30 + 2 = 32 in
A ball is thrown into the air. Its height (in feet) t seconds later is given by h(t)=64t−16t^2 a) What is the height of the ball 1 second after it has been thrown? b) After how many seconds does the ball hit the ground? c) At what time(s) is the ball 30 feet above the ground?
Answer:
A) 48 feet
B) 4 seconds
C) 0.54 seconds and 3.46 seconds
Step-by-step explanation:
So we have the function:
[tex]h(t)=64t-16t^2[/tex]
Which represents the height h(t) of the ball after t seconds.
A)
To find the height of the ball 1 second after it has been thrown, substitute 1 for t. Thus:
[tex]h(1)=64(1)-16(1)^2[/tex]
Simplify:
[tex]h(1)=64-16[/tex]
Subtract:
[tex]h(1)=48[/tex]
So, after 1 second, the height of the ball is 48 feet above the ground.
B)
To find out how many seconds after being thrown does the ball hit the ground, we'll set h(t) to 0. 0 means that it will be 0 feet above ground level: in other words, on the ground. So:
[tex]0=64t-16t^2[/tex]
Solve for t. Factor out a 16t:
[tex]0=16t(4-t)[/tex]
Zero Product Property:
[tex]16t=0\text{ or } 4-t=0[/tex]
Solve for t:
[tex]t=0\text{ or } t=4[/tex]
We'll ignore the first zero. So, the ball lands after 4 seconds of being thrown into the air.
C)
To find out at what time(s) the ball is 30 feet above the ground, set h(t) to 30 and solve for t:
[tex]30=64t-16t^2[/tex]
First, divide everything by 2 to simplify things:
[tex]15=32t-8t^2[/tex]
Subtract 15 from both sides:
[tex]-8t^2+32t-15=0[/tex]
Now, to find the zeros, we can use the quadratic formula. a is -8, b is 32, and c is -15. Thus:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Substitute:
[tex]x=\frac{-32\pm\sqrt{32^2-4(-8)(-15)}}{2(-8)}[/tex]
Simplify:
[tex]x=\frac{32\pm\sqrt{544}}{16}[/tex]
Use a calculator. Approximate:
[tex]x\approx0.5422\text{ or } x\approx 3.4577[/tex]
So, the ball is 30 feet above the ground after 0.54 seconds and 3.46 seconds.
And we're done :)
Solve 10-5x+1=7x+11-12
Answer:
x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
10−5x+1=7x+11−12
Step 1: Simplify both sides of the equation.
10−5x+1=7x+11−12
10+−5x+1=7x+11+−12
(−5x)+(10+1)=(7x)+(11+−12)(Combine Like Terms)
−5x+11=7x+−1
−5x+11=7x−1
Step 2: Subtract 7x from both sides.
−5x+11−7x=7x−1−7x
−12x+11=−1
Step 3: Subtract 11 from both sides.
−12x+11−11=−1−11
−12x=−12
Step 4: Divide both sides by -12.
−12x
