Answer:

Step-by-step explanation:

Given,

Volume = 5600 sq.ft

Length = 35 ft

Width = 8 ft

Therefore,

By the problem,

[tex]height = \frac{volume}{length \times width} [/tex]

[tex] = > h = \frac{5600}{35 \times 8} ft[/tex]

=> h = 20 ft (Ans)

Yellow is the right answer.

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°.

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.

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

Answer:

Two independent sample t test

Step-by-step explanation:

The research described describes the statistics of two different samples which are also independent,

Sample 1 :

Sample size, n1 = 16

Mean, xbar = 4.75

Standard deviation s2 = 2.8

Sample 1 :

Sample size, n1 = 15

Mean, xbar = 3.93

Standard deviation s2 = 2.4

The hypothesis :

H0 : μ1 = μ2

H1 : μ1 ≠ μ2

The t statistic :

(xbar1 - xbar 2) ÷ sqrt[(s1²/n1 + s2²/n2)

From on the test statistic, obtain the p value and compare with Given α - value to make and conclude in a decision.

The correct answer is option c.

How graph is analyzed?

If we have function, then first we will find ordered pairs then will draw the graph and then will analyze the changes in the graph.

Compute the y values of the function at the given x values by substituting all the x values into the given function individually and make a table like Fig 1.

We will draw all the points of the table on the graph and will join them.

From the graph, it is clearly visible that the curve is decreasing while moving from left to right.

Therefore, the correct option is c.

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

Step-by-step explanation:

Answer:

[tex] y + 6 = -2(x - 4) [/tex]

Step-by-step explanation:

Given:

Slope (m) = -2

Point on the line = (4, -6)

Required:

Point-slope equation of the line

Solution:

Point-slope equation takes the following form:

[tex] y - b = m(x - a) [/tex],

Where,

m = slope of the line = -2

(a, b) = coordinates of the point on the line. = (4, -6)

Plug in the values into the slope-point equation

[tex] y - (-6) = -2(x - 4) [/tex]

[tex] y + 6 = -2(x - 4) [/tex]

Answer:

[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]

Answer:

[tex]4 \times - 2 {}^{n - 1} [/tex]

Step-by-step explanation:

Use the formula.

[tex]f(n) = f(1) \times {r}^{n - 1} [/tex]

where f(1) is the first terms, r is the common ratio, and n is our undefined term.

4 is our first term. so

f(1)=4.

Our common ratio is -2 so

r=-2.
