The probability that exactly 12 of them are strikes is 0.09.
In this question,
Number of pitches, n = 22
Probability of throwing a strike for each pitch, p = 0.431
Then, q = 1 - p
⇒ q = 1 - 0.431
⇒ q = 0.569
Number of strikes, x = 12
The probability that exactly 12 of them are strikes can be calculated using Binomial expansion,
[tex]P(X=x)=nC_xP^{x}q^{(n-x)}[/tex]
⇒ [tex]P(X=12)=22C_{12}(0.431)^{12}(0.569)^{(22-12)}[/tex]
⇒ [tex]P(X=12)=22C_{12}(0.431)^{12}(0.569)^{10}[/tex]
⇒ [tex]P(X=12)=(\frac{22!}{12!10!} )(0.431)^{12}(0.569)^{10}[/tex]
⇒ P(X=12) = (646646)(0.000041)(0.00355)
⇒ P(X=12) = 0.09431 ≈ 0.09
Hence we can conclude that the probability that exactly 12 of them are strikes is 0.09.

Which of these is a simplified form of the equation 7y 8 = 9 3y 2y? 7y = 6 2y = 1 12y = 17 5y = 17
The simplified equation of 7y + 8 = 9 + 3y + 2y is 2y = 1
How to simplify an equation?The equation can be simplified as follows:
7y + 8 = 9 + 3y + 2y
We have to combine like terms
Hence,
7y + 8 = 9 + 3y + 2y
7y + 8 = 9 + 5y
subtract 5y from both sides
7y - 5y + 8 = 9 + 5y - 5y
2y + 8 = 9

If csc(x)=7, for 90 deg
sin(x/2)=
cos(x/2)=
tan(x/2)=
The values of trigonometric functions sin(x/2) is [tex]\sqrt{\frac{7+4\sqrt{3}}{14}}[/tex], cos(x/2) is [tex]\frac{1}{\sqrt{14(7+4\sqrt{3})}}[/tex] and tan(x/2) is 7+4√3.
Given that the value of trigonometric function csc(x)=7 for 90°<x<180°.
We are given:
csc(x)=7 Where: 90° < x < 180°
This interval indicates that the angle x in the second quadrant and we know that at that quadrant sin(x) and CSC(x) functions are positive and all other trigonometric functions sign are negative.
Now:
sin(x)=1/csc(x)
sin(x)=1/7
Using the trigonometric identity sin²x+cos²x=1, we get
cosx=±√(1-sin²x)
cosx=±√(1-(1/7)²)
cosx=±√((49-1)/49)
cosx=±(4√3)/7
As x is in second quadrant.
Therefore, cosx=-(4√3)/7
consider the inequality, 90°<x<180°
Divide by 2, we get
45°<x/2<90°
This is the angle x/2 in the first quadrant and in that quadrant all functions sign are positive.
Substitute the value of cosx in half angle formula for sine function,
[tex]\begin{aligned}\cos x&=1-2\sin^2\left(\frac{x}{2}\right)\\ -\frac{4\sqrt{3}}{7}&=1-2\sin^2\left(\frac{x}{2}\right)\\ 2\sin^2 \frac{x}{2}&=1+\frac{4\sqrt{3}}{7}\\\sin \frac{x}{2}&=\pm\sqrt{\frac{7+4\sqrt{3}}{14}}\end[/tex]
As x/2 lies in first quadrant then [tex]\sin \frac{x}{2}=\sqrt{\frac{7+4\sqrt{3}}{14}}[/tex]
Again, Substitute the value of cosx in half angle formula for sine function,[tex]\begin{aligned}\sin x&=2\sin\left(\frac{x}{2}\right)\cos\frac{x}{2}\\ \frac{1}{7}&=2\sqrt{\frac{7+4\sqrt{3}}{14}}\cos\left(\frac{x}{2}\right)\\ \cos \frac{x}{2}&=\frac{1}{14\times\frac{\sqrt{7+4\sqrt{3}}}{\sqrt{14}}}\\\cos \frac{x}{2}&=\frac{1}{\sqrt{14(7+4\sqrt{3})}}\end[/tex]
Now find tan(x/2) as shown below, we get
[tex]\begin{aligned}\tan\frac{x}{2}&=\frac{\sin\frac{x}{2}}{\cos \frac{x}{2}}\\&=\frac{\sqrt{7+4\sqrt{3}}}{\sqrt{14}}\times \frac{\sqrt{14}\sqrt{7+4\sqrt{3}}}{1}\\&=7+4\sqrt{3}\end[/tex]
Hence, when trigonometric function csc(x)=7 for 90°<x<180° then sin(x/2) is [tex]\sqrt{\frac{7+4\sqrt{3}}{14}}[/tex], cos(x/2) is [tex]\frac{1}{\sqrt{14(7+4\sqrt{3})}}[/tex] and tan(x/2) is 7+4√3.

Kim has $10$ identical lamps and $3$ identical tables. How many ways are there for her to put all the lamps on the tables
There are 66 ways Kim can put the 10 identical lamps on the 3 identical tables
How to determine the number of ways?The given parameters are:
Identical lamps, n = 10Identical tables, r = 3The combination involving identical objects is calculated using:
(n + r - 1)C(r - 1)
So, we have:
n + r - 1 = 10 + 3 - 1
Evaluate the sum
n + r - 1 = 13 - 1
Evaluate the difference
n + r - 1 = 12
Also, we have:
r - 1 = 3 - 1
Evaluate the difference
r - 1 = 2
So, we have:
(n + r - 1)C(r - 1) = 12C2
Apply the following combination formula:
nCr = n!/((n - r)!r!)
So, we have:
12C2 = 12!/((12 - 2)! * 2!)
Evaluate the difference
12C2 = 12!/(10! * 2!)
Expand the numerator
12C2 = 12 * 11 * 10!/(10! * 2!)
Evaluate the quotient
12C2 = 12 * 11/2!
Expand the denominator
12C2 = 12 * 11/2 * 1
Evaluate the product
12C2 = 132/2
Evaluate the quotient
12C2 = 66
Hence, there are 66 ways Kim can put the 10 identical lamps on the 3 identical tables

Direct variation is modeled by the equation y = kx, where k is a constant and x and y vary based on the other's value.
We'll first need to find k, also known as the constant of variation, using our given values of x and y.
6 = k * -7
k = -6/7
Now that we have k, we can plug it in and substitute other values in for x or y. In this case, we'll plug in 4 for x and solve for y.
y = -6/7x
y = -6/7 * (4)
y = -24/7
y = -24/7
Hope this helps!
Answer:
y = -24/7
Step-by-step explanation:
We can use proportions for this question since y varies directly with x. This means that if x changes, y changes along with the x, and vice versa.
When y = 6, x = -7, so the proportion will be 6 : -7.
We need to find the y when x is 4, so our equation will be:
6 : -7 = y : 4
Since the proportion will be the same.
Next, we multiply the inner two numbers, and the outer two numbers, saying that the values are the same.
-7y = 24
y = 24 / -7
y = - 24/7
So y = -24/7 will be our answer!

Alice and Bob are currently 1000 feet apart and are both running directly
toward each other at a constant speed of 10 feet per second. A bird starts in the same
position as Alice and flies directly toward Bob at a speed of 20 feet per second. When the
bird reaches Bob, it turns around immediately and starts flying toward Alice at the same
speed, turning around immediately when it reaches Alice, and repeating this procedure until
Alice and Bob meet. When Alice and Bob finally meet, what is the total distance that the
bird has flown, in feet?
The distance the bird has flown by the time Alice and Bob meet is 40 feet.
What is the distance?Distance is a measurement of time and speed.
The distance equals speed multiplied by time.
Data and Calculations:Distance between Alice and Bob = 1,000 feet
Distance between the bird and Bob = 1,000 feet
Speed of Alice and Bob = 10 feet per second, respectively
The combined speed of Alice and Bob = 20 feet per second
Since the two are running directly toward each other, the distance each will cover at the meeting point is 50 feet (1,000/20)
The time covered at the meeting point = 20 seconds (1,000/50)
Speed of the bird = 20 feet per second
The distance covered by the bird towards Bob at their meeting point is 40 feet (20 feet x 20 seconds)
Thus, the total distance covered by the bird at the meeting point is 40 feet.

A private jet flies the same distance in 10 hours that a commercial jet flies in 7 hours. if the speed of the commercial jet was 144mph less than 2 times the speed of the private jet, find the speed of each jet.
The speed of private jet is = 252 mph
The speed of commercial jet is = 360 mph
What is speed ?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.Let the speed of private jet be x mph.
Then the speed of commercial jet will be = 2x - 144
Equation forms:
10x = 7 ( 2x - 144 )
Solving for x
10x = 14x - 1008
⇒ 10x - 14x = - 1008
⇒ - 4x = - 1008
⇒ x = 252
So, x = 252
Hence, the speed of private jet is = 252 mph

A glassware seller bought 1000 glass tumblers. 100 of them were broken and she sold the remaining tumbler at Rs 80 each. If she made a loss of 4%, at what proce did she purchase each tumbler?
Answer:
$75
My answer might be a bit off since I'm not really sure what you mean by "Rs 80", which I interpreted as $80, but if my interpretation is wrong, you can still use all the same steps and you should get the correct answer
Step-by-step explanation:
So we can represent the price of each tumbler as the variable "P", since it's some unknown value we're solving for. Let's also just say that "T" is the total price that she paid for all of the tumblers.
Using this equation we can derive the following equation.
1000P = T
Since multiplying the price of each glass tumbler times the price of one glass tumbler should equal the entire price.
Now she only sold 900 of them, since 100 were broken, and she sold them each for 80. So knowing this we can find how much she made in total from selling the remaining 900 glass tumblers
900 * 80 = 72,000
Now if she made a loss of 4%, that means the total money she made back, is only 96% the amount of money she paid for the product. The reason for this is (100-4)% represents a 4% loss.
Remember, how T represents the entire price, well we know that 72,000 represents 96% of it's value. To find what x% is of some number, you generally convert the percentage into a decimal by dividing by 100, so to find x% of some variable "a" you generally use the following equation: [tex]a*\frac{x}{100}[/tex] where the value of this expression will be equal to x% of a.
So let's convert 96% to decimal form: [tex]\frac{96}{100} = 0.96[/tex]. Now if we multiply this decimal 0.96 by T, we should get 72,000 since the 72,000 represents 96% of the original value
[tex]0.96T = 72,000[/tex]
To find the original value of T, we simply divide both sides by 0.96
[tex]T = 75,000[/tex]
So now that we know the original total price, we can use the original equation we derived to solve for P, which represents the price of each individual tumbler.
Original Equation
[tex]1000P = T[/tex]
Substitute 75,000 as T
[tex]1000P = 75,000[/tex]
Divide both sides by 1,000
[tex]75=P[/tex]
This means she sold each for 75
