The probability of hitting a target is 1/8. What is the probability of hitting the target exactly twice in five tries
Answer:
[tex]P(X=2) = 0.1047[/tex]
Step-by-step explanation:
Represent the probability of hitting the target with H.
So:
[tex]H = \frac{1}{8}[/tex]
Represent the probability of not hitting the target with T.
So:
[tex]T = 1 - H[/tex]
[tex]T =1 - \frac{1}{8}[/tex]
[tex]T =\frac{7}{8}[/tex]
Required
Probability of exactly 2 hits in 5 tries
This probability is a binomial probability and will be calculated using:
[tex]P(X=x) = ^nC_x H^xT^{n-x}[/tex]
In this case:
[tex]x = 2[/tex] i.e 2 hits
[tex]n = 5[/tex] i.e. 5 attempts
So, we have:
[tex]P(X=2) = ^5C_2 H^2T^{5-2}[/tex]
[tex]P(X=2) = ^5C_2 H^2T^3[/tex]
Apply combination formula:
[tex]P(X=2) = \frac{5!}{(5-2)!2!} H^2T^3[/tex]
[tex]P(X=2) = \frac{5!}{3!2!} H^2T^3[/tex]
[tex]P(X=2) = \frac{5*4*3!}{3!2*1} H^2T^3[/tex]
[tex]P(X=2) = \frac{5*4}{2} H^2T^3[/tex]
[tex]P(X=2) = 10* H^2T^3[/tex]
Substitute values for H and T
[tex]P(X=2) = 10* (\frac{1}{8})^2(\frac{7}{8})^3[/tex]
[tex]P(X=2) = 10* \frac{1}{64}*\frac{343}{512}[/tex]
[tex]P(X=2) = \frac{3430}{32768}[/tex]
[tex]P(X=2) = 0.1047[/tex]
Hence, the probability of 2 hits in 5 tries is 0.1047
In a certain town, 23% of males have a beard. In random samples of 25 men from
this town, what are the mean and standard deviation of the number of men with
a beard?
Answer:
Mean μ = 5.75
Standard deviation σ = 2.1041
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' = 25
Given proportion p= 23% = 0.23
Let 'X' be the random variable in a binomial distribution
Mean μ = np = 25 × 0.23 = 5.75
Step(ii):-
Standard deviation
σ = √npq
σ = [tex]\sqrt{25 X 0.23 X0.77}[/tex]
σ = 2.1041

The two quantitative elements of process variation are: Select one: a. common cause and special cause b. median and variance c. central tendency and spread d. inspection and detection
Answer:
The two quantitative elements of process variation are:
a. common cause and special cause.
Step-by-step explanation:
When a process fails to follow the prescribed process pattern, with reduced productivity, higher costs, longer lead times, and late deliveries, a process variation has occurred. Thus, process variation is a leading cause of quality issues. There are common cause variation, which is inherent in the system itself, and special cause variation, which is caused by external factors outside of the system. Process variations can be reduced by reducing the common and special cause variations, among other steps.

how do i solve it in 6th grade math?
Answer: what is the question
Step-by-step explanation:
A group is diving at an depth of 20 feet. If they rise 20 feet, their new elevation will.
A. end up at exactly 0 feet of elevation.
B. result in a positive elevation.
C. result in a negative elevation.
D. be less than it was before.
Answer:
A. end up at exactly 0 feet of elevation.
Step-by-step explanation:
This is because, at a depth of 20 feet, their position is -20 feet below the water surface. If they rise by 20 feet, we add 20 feet to their current position to reach their new position.
So, -20 feet + 20 feet = 0 feet.
So, their new elevation will end up at exactly 0 feet of elevation.

Factor out the GCF of 18x3y4+24x2y5
(A) 6x3y5(7)
(B) 6(3x3y4+4x2y5)
(C) 6x2y4(3x+4y)
(D) 42x5y9
Answer:
c
Step-by-step explanation:
18x³y⁴ = 2 * 3 * 3 * x³ * y⁴
24x²y⁵ = 2 * 2 * 2 * 3 * x² * y⁵
GCF = 2 * 3 * x² * y⁴ = 6x²y⁴
18x³y⁴ + 24x²y⁵ = 6x²y⁴(3x + 4y)

Answer:
[tex]y = 4x - 12[/tex]
Step-by-step explanation:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that [tex]m = 4[/tex].
So
[tex]y = 4x + b[/tex]
Contains point (1,-8).
This means that when [tex]x = 1, y = -8[/tex]. We replace this into the equation to find b. So
[tex]y = 4x + b[/tex]
[tex]-8 = 4(1) + b[/tex]
[tex]b = -12[/tex]
So
[tex]y = 4x - 12[/tex]
Tyre measured the average monthly temperature in degrees Fahrenheit for several months. If February is set ect 2 and June is oud to 6 what function best models these data from February to June?
Answer:
it will be d
Step-by-step explanation:
Answer:
f(x)=11x+12
Step-by-step explanation:
it shows that the intercept is around halfway between 0 and 20, and the plots are not exactly at the 10s marks, if you look- June is supposed to be 6, but it’s closer to 66. since 6*11=66, i’d say 11x+12 is the answer.

f(x)=x^2+8x-10 find f(a)+5
Answer:
We conclude that:
f(a) + 5 = a² + 8a - 5
Step-by-step explanation:
Given
The function is given by
f(x) = x²+8x-10
To determine
f(a)+5
In order to determine f(a)+5, first, we need to determine f(a).
Now substitute x = a in the function f(x) = x²+8x-10
f(a) = (a)² + 8(a) - 10
f(a) = a² + 8a - 10
Thus,
f(a) + 5 = (a² + 8a - 10) + 5
f(a) + 5 = a² + 8a - 5
Therefore, we conclude that:
f(a) + 5 = a² + 8a - 5
In his Fourteen Points, why did President Wilson include resolutions specifically about European
territories?
A Wilson insisted that Germany should take public responsibility for starting the war that had
destroyed many territories.
B The Treaty of Versailles did not include any detailed restrictions on territorial boundaries
C Territorial disputes among European nations were a major reason the war began in the first
place
D There was a strong international push for freedom of the seas and the reduction of armaments
Answer:
The correct answer is C. President Wilson included resolutions specifically about European territories in his Fourteen Points because territorial disputes among European nations were a major reason the war began in the first place.
Step-by-step explanation:
The Fourteen Points were the pacifist plan devised by President Woodrow Wilson at the end of World War I, with the aim of avoiding tensions between the former European combatants of the conflict and thus achieve a lasting peace between nations, framed in the League of Nations as supranational entity. Basically, the Fourteen Points sought to avoid the imposition of excessive sanctions on the defeated, as well as the obtaining of great benefits by the winners, so as not to break the territorial status quo prior to the war and thus avoid generating tensions in the future.
Answer:
C.) Territorial disputes among European nations were a major reason the war began in the first place.

Simplify sin θ/cosθ tan θ to a number or a single trigonometric function
Answer:
The answer is below
Step-by-step explanation:
Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.
Some trigonometric identities are:
secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.
Hence simplifying the question:
[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]
A store in Melrose, Massachusetts advertised a 35-mm camera for $259.99 and a wide-angle lens for $89.99. What is the total purchase price if the state sales tax rate is 6 percent
Answer:
The total purchase price is $370.97.
Step-by-step explanation:
Given;
price of the 35-mm camera, = $259.99
price of the wide-angle lens = $89.99
TAX rate = 6% = 0.06
The total purchase price = 0.06($259.99 + $89.99) + ($259.99 + $89.99)
The total purchase price = $20.99 + 349.98
The total purchase price = $370.97
Therefore, the total purchase price is $370.97.
