Find the value of x in the triangle shown below 8 2
Answers
In the triangle in question, x has a value of √68. The triangle is right - angled triangle based on the dimensions provided. According to this, the neighboring angle will also be x°.
What is an angle?An angle is a shape made up of two rays that share a terminus and is designated by the name of the angle (the vertex).
The plane that contains the rays contains the angles created by two beams. The meeting of two planes might also result in an angle. These are referred to as dihedral angles.
An angle is created when two straight lines or rays intersect at the same point. The point where all points converge is known as an angle's vertex.
The Roman word angulus, which means "corner," is where the term "angle" comes from. In plane geometry, an angle is a shape made up of two rays or lines with the same termination.
In the triangle in question, x has a value of √68.
The triangle is right- angled triangle based on the dimensions provided. According to this, the neighboring angle will also be √68.
Therefore, a given triangle's angles will all be expressed mathematically as -
Using Pythagoras theorem,
[tex]x^{2} = 8^2 + 2^2\\x^{2} = 64 + 4\\x^{2} = 68\\x = \sqrt{68}[/tex]
As a result, the given triangle's x value is √68.

[tex]f(8) = 81[/tex]
[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]
Step-by-step explanation:
Solving (a):
[tex]f(x) = x^2 + 2x +1[/tex]
[tex]g(x) = x - 5[/tex]
Solve for f(8)
We have:
[tex]f(x) = x^2 + 2x +1[/tex]
Substitute 8 for x
[tex]f(8) = 8^2 + 2*8 +1[/tex]
Solve
[tex]f(8) = 64 + 16 +1[/tex]
[tex]f(8) = 81[/tex]
Solving (b):
[tex](g\ o\ f)(x)[/tex]
This is solved by:
[tex](g\ o\ f)(x) = g(f(x))[/tex]
So, we have:
[tex]g(x) = x - 5[/tex]
[tex]g(f(x)) = f(x) - 5[/tex]
Substitute: [tex]f(x) = x^2 + 2x +1[/tex]
[tex]g(f(x)) = x^2 + 2x + 1 - 5[/tex]
[tex]g(f(x)) = x^2 + 2x -4[/tex]
Hence:
[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]
Laurel divided 2/3 of a gallon of paint into 4 containers. How much of the of the
paint was put into each container?
Answers
Answer: 1/6 of the paint went to each container
Step-by-step explanation: Since we know he had 2/3 of a gallon of paint and they were divided into 4 containers, we have to divide 2/3 by 4 and when you do that you get 0.16666 continuous but in fraction for you arrive at 1/6 of a gallon of paint

Data was collected from a simple random sample of 200 cell phone users age 18 or older in the United States. Each user was categorized by age-group and by whether he or she uses a certain cell phone app. The table shown summarizes the data, with expected cell counts in parentheses.
Uses Cell Phone App
Yes No Total
Age-Group Young Adults 4 (15.2) 76 (64.8) 80
Older Adults 29 (19.38) 73 (82.62) 102
Elderly Adults 5 (3.42) 13 (14.58) 18
Total 38 162 200
Which statement is true about whether the conditions for a chi-square test for independence have been met?
A. All necessary conditions are satisfied to apply a chi-square test for independence between age group and texting use by cell phone users.
B. The data from the different age groups are not the result of independent random samples; therefore, the conditions for the test are not met
C. The total sample size in one or more of the age-groups is too small to meet the conditions of the chi-square test for independence.
D. Not all of the observed cell counts are large enough to satisfy the conditions for the chi-square test for independence.
E. Not all of the expected cell counts are large enough to satisfy the conditions for the chi-square test for independence

Answer:
√29
Step-by-step explanation:
We can call the given points A(3, 4) and B(-2, 6).
The right triangle with segment AB as a hypotenuse can best be drawn along grid lines. Then the vertical leg is the difference of y-coordinates: 6-4 = 2, and the horizontal leg is the difference of x-coordinates: 3 -(-2) = 5.
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs.
AB² = 2² + 5²
AB² = 4 + 25 = 29
Taking the square root, we find the length of the line segment between the points to be ...
AB = √29

A company categorizes its employees in three groups: I, II, and III, which constitute 20%, 60%, and 20% of the workforce respectively. Furthermore, 10%, 20%, 5% employees of group I, II, III respectively are considered certified. Given that a randomly picked employee is not certified, what is the probability that this employee belongs to group I?
Answers
Answer:
the probability that this employee belongs to group I is 0.2118
Step-by-step explanation:
Given the data in the question;
P( group 1 ) = 0.20
P( group 11 ) = 0.60
P( group 111 ) = 0.20
now
[tex]P( \frac{certified}{Group1} )[/tex] = 0.10
[tex]P( \frac{Not-certified}{Group1} )[/tex] = 0.90
[tex]P( \frac{certified}{Group11} )[/tex] = 0.20
[tex]P( \frac{Not-certified}{Group11} )[/tex] = 0.80
[tex]P( \frac{certified}{Group111} )[/tex] = 0.05
[tex]P( \frac{Not-certified}{Group111} )[/tex] = 0.95
so
[tex]P( \frac{group1}{Not-certisfied} )[/tex] = [ [tex]P( \frac{Not-certified}{Group1} )[/tex] × P( group 1 ) ] / [ [tex]P( \frac{Not-certified}{Group1} )[/tex] × P( group 1 ) + [tex]P( \frac{Not-certified}{Group11} )[/tex] × P( group 11 ) + [tex]P( \frac{Not-certified}{Group111} )[/tex] × P( group 111 ) ]
we substitute
[tex]P( \frac{group1}{Not-certisfied} )[/tex] = [ 0.90×0.20 ] / [ 0.90×0.20 + 0.80×0.60 + 0.95×0.20
[tex]P( \frac{group1}{Not-certisfied} )[/tex] = 0.18 / [ 0.18 + 0.48 + 0.19 ]
[tex]P( \frac{group1}{Not-certisfied} )[/tex] = 0.18 / 0.85
[tex]P( \frac{group1}{Not-certisfied} )[/tex] = 0.2118
Therefore, the probability that this employee belongs to group I is 0.2118
