Find the number of permutations of the letters of the word LOOPHOLE
Answer:
6!/3!=6x5x4x3x2/3x2=6x5x4=120
Step-by-step explanation:
There are L, O, O, P, H, O, L, E; 8 letters in LOOPHOLE. However, three letters repeat: OOO. That means we cannot count them as different and use ! for them.
L,P,H,L,E,O are the letters not double counted. There are SIX letters, so 6!, however, you still have to divide since there are the Os you have to consider.
You have to divide by 3! as they repeat 3 times.
Thus, 6!/3!
"There is a subset of permutations that takes into account that there are double objects or repetitions in a permutation problem. In general, repetitions are taken care of by dividing the permutation by the factorial of the number of objects that are identical" -www. ck12. org > probability > lesson > permutation
there were 3 coins and they were tossed 200 times total. 23 times, 3 of them showed heads, 72 times, 2 of them showed heads, 77 times, 1 of them showed heads, 28 times, 0 showed heads. whats probability for each of the events?
Answer:
Step-by-step explanation:
If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.Solution:Probability of an event, P(E) = Number of occurrences where the event takes place / Total number of occurrencesThe probability of 2 heads coming up when three coins are tossed simultaneously is given by the ratio of the number of times a particular outcome occurs to the total number of tosses.Total number of tosses = 200Number of 2 heads outcomes = 72Probability of 2 heads outcomes = Number of 2 heads outcomes / Total number of tosses= 72/200= 9/25

Which expression is equivalent to
(3^2) ^-2. -81 , -12 , 1/81 , 1/12
Answer:
1/81
Step-by-step explanation:
First lets simplfy the equation :
(3^2)^-2
(remember that you can mutiply the exponent outside the paranthesis by the exponent inside so -2*2=-4)
3^-4
Now lets evaluate this further!
3^-4
(negative exponets mean that you have to raise the number but as the denominator of a fraction)
1/3^4
Now we can solve it fully
1/3^4
1/81

7ײ+9ײ-ײ
Step-by-step explanation:
7x² + 9x² - x²
when you wrote the expression you used the "multiplication ×" and not "x".
anyway, when you have terms of the same variable of the same exponent, then the combination variable and exponent become an item. and the same items can simply be added in an expression.
this is similar to
7 apples + 9 apples - 1 apple
what would you do there ?
see ?
and the same we are doing now for the given expression : we are adding the terms up :
7x² + 9x² - x² = (7 + 9 - 1)x² = 15x²
and in the middle I gave you even the reason why we can do that.

Answer:
C
Step-by-step explanation:
While playing a real-time strategy game, Juan created military units for battle: long swordsmen, spearmen, and crossbowmen.
Long swordsmen require 75 units of food and 25 units of gold. Spearmen require 40 units of food and 30 units of wood.
Crossbowmen require 30 units of wood and 40 units of gold. If Juan used 1475 units of gold, 1500 units of wood, and 4025 units
of food to create the units, how many of each type of military unit did he create?
Juan created
long swordsmen.
Parti
Juan created 35 long swordsmen, 35 spearmen and 15 crossbowmen.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represnt the number of long swordsmen, y represent the spearmen and z represent the crossbowmen. Hence:
75x + 40y = 4025 (1)
25x + 40z = 1475 (2)
And:
30y + 30z = 1500 (3)
Hence;
x = 35, y = 35 and z = 15
Juan created 35 long swordsmen, 35 spearmen and 15 crossbowmen.

Prove that y=tan(mx) = sin(mx)/cos(mx)
The equation tan(mx) = sin(mx)/cos(mx) is a trigonometry equation
The trigonometry equation tan(mx) = sin(mx)/cos(mx) is true
How to prove the statement?The equation is given as:
tan(mx) = sin(mx)/cos(mx)
The tangent of an angle is the ratio of the sine and the cosine of the angle.
This means that:
tan(α) = sin(α)/cos(α)
By comparison, we have:
α = mx
Substitute α = mx in tan(α) = sin(α)/cos(α).
So, we have:
tan(mx) = sin(mx)/cos(mx)
Hence, the trigonometry equation tan(mx) = sin(mx)/cos(mx) is true

Answer:
1, 4 or -1, -4
Step-by-step explanation:
Let the two numbers be x and such that x > y.
According to the first condition:
[tex]x^2 -y^2= 15[/tex]
[tex]\implies x^2 =y^2+15[/tex]......(1)
According to the second condition:
[tex]3x^2 +y^2= 49[/tex]
[tex]\implies 3(y^2+15) +y^2= 49[/tex]
(From equation 1)
[tex]\implies 3y^2+45 +y^2= 49[/tex]
[tex]\implies 4y^2 =49-45[/tex]
[tex]\implies 4y^2 =4[/tex]
[tex]\implies y^2 =\frac{4}{4}[/tex]
[tex]\implies y^2 =1[/tex]
[tex]\implies y =\pm 1[/tex]
When y = 1
[tex]\implies x^2 =(1)^2+15=1+15=16[/tex]
[tex]\implies x =\pm 4[/tex]
When y = -1
[tex]\implies x^2 =(-1)^2+15=1+15=16[/tex]
[tex]\implies x =\pm 4[/tex]
Thus, the required numbers are either 1, 4 or -1, -4
barbara purchased stock last year for 8500 and paid a 1.25% broker fee. she sold it for 7324 and had to pay a .5% broker fee.
Barbara's net loss on the sale of the stocks she purchased last year is 1245.63.
What is the net loss?A net loss is earned when the cost price of purchasing the stock is greater than the selling price.
Net loss = cost price - selling price
Cost price = 8500 + (8500 x 1.25%) = 8606.25
Selling price = 7324 + (7324 x 0.5%) = 7360.62
Net loss = 8606.25 - 7360.62 = 1245.63

Using mathematically precise language, explain in detail how you would multiply the complex number z1=r1 (cos theta1+isin theta 1) with the complex number z2=r2 (cos theta 2+isin theta 2)
Answer:
Multiply the moduli and add the arguments.Step-by-step explanation:First write out the two terms being multiplied: z1z2= [r1(cos(theta 1) + isin(theta 1))][r2(cos(theta 2)+ isin(theta 2))] z1z2= r1r2 (cos(theta 1) + isin(theta 1))(cos(theta 2)+ isin(theta 2)) z1z2= r1r2(cos(theta 1)cos(theta 2))+(icos(theta 1)sin(theta 2))+(icos(theta 2)sin(theta 1))+(i^2 sin(theta 1)sin(theta 2)) Next group and rewrite the like term with the sums and differences. Your answer is the multiplication of the moduli and the addition of the arguments: z1z2= r1r2[cos(theta 1 + theta 2) + i sin (theta 1 and theta 2)].
The product complex number is [tex]z_1z_2[/tex]= [tex]r_1r_2[/tex][cos (θ1+θ2) + i sin (θ1+θ2)].
What is Complex number?A real number and an imaginary number are effectively combined to create a complex number. The complex number is written as a+ib, where a and ib are real and imaginary numbers, respectively.
We have,
z1=r1 (cos θ1 +i sin θ1)
z2=r2 (cos θ2 +i sin θ2)
where r-radius/radii
and, m-modulus/moduli
Now, the product is
[tex]z_1z_2[/tex] = r1 (cos θ1 +i sin θ1) x r2 (cos θ2 +i sin θ2)
[tex]z_1z_2[/tex] = r1 r2(cos θ1 . cos θ2 +i cos θ1 sin θ2 + i sin θ1 cos θ2 + i² sin θ1 sin θ2)
[tex]z_1z_2[/tex] = r1 r2(cos θ1 . cos θ2 +i cos θ1 sin θ2 + i sin θ1 cos θ2 - sin θ1 sin θ2)
We know,
cos (a + b)= cos a cos b - sin a sin b
sin (a+b) = sin a cos b + cos a sin b
Thus, [tex]z_1z_2[/tex] = [tex]r_1r_2[/tex][cos (θ1+θ2) + i sin (θ1+θ2)].

Assume that Quick Release lets go of the ball 6 feet above the ground and the receiver
catches it 6 feet above the ground. The ball reaches a maximum height of 16 feet above
the ground halfway to the receiver. Write an algebraic rule that models the path of the
football. Show all your work and explain your reasoning.
The equation that models the path of the football released from the given position is h(t) = -10 + 25.37t - 16.1t².
Initial velocity of the ball
The initial velocity of the ball is determined by applying third kinematic equation as shown below;
Vf² = V₀² - 2gh
at maximum height, the final velocity, Vf = 0maximum height reached from the point of projection, = 16 ft - 6ft = 10 ft0 = V₀² - 2gh
V₀² = 2gh
V₀ = √(2gh)
V₀ = √(2 x 32.17 x 10)
V₀ = 25.37 ft/s
Equation of motion of the ballThe equation of the ball's motion can be modelled as follows;
h = V₀t - ¹/₂gt²
10 = 25.37t - ¹/₂(32.17)t²
10 = 25.37t - 16.1t²
h(t) = -10 + 25.37t - 16.1t²
Thus, the equation that models the path of the football at any given position is h(t) = -10 + 25.37t - 16.1t².

Step-by-step explanation:
[tex]\sf \cfrac{x^2+10+25}{x+5}-\cfrac{x^2-6}{x-5}[/tex]
First, Let's factor the expressions that are not already factored in x^2+10+25/x+5
