Answer:

Follows are the solution to this question:

Step-by-step explanation:

In the given question some of the data is missing so, its correct question is defined in the attached file please find it.

Let

A is quality score of A

B is quality score of B

C is quality score of C

[tex]\to P[A] =0.55\\\\\to P[B] =0.28\\\\\to P[C] =0.17\\[/tex]

Let F is a value of the content so, the value is:

[tex]\to P[\frac{F}{A}] =0.15\\\\\to P[\frac{F}{B}] =0.12\\\\\to P[\frac{F}{C}] =0.14\\[/tex]

Now, we calculate the tooling value:

[tex]\to p[\frac{C}{F}][/tex]

using the baues therom:

[tex]\to p[\frac{C}{F}] = \frac{p[C] \times p[\frac{F}{C} ]}{p[A] \times p[\frac{F}{A}] + p[B] \times p[\frac{F}{B}]+p[C] \times p[\frac{F}{C}] }[/tex]  

            [tex]= \frac{ 0.17 \times 0.14 }{0.55 \times 0.15 + 0.28 \times 0.12 + 0.17 \times 0.14 } \\\\= \frac{0.0238}{0.0825 + 0.0336 + 0.0238} \\\\= \frac{0.0238}{0.1399} \\\\=0.1701[/tex]

Answer: x^2+6x+9

Step-by-step explanation:

this will factor out to

X^2+6x+9

Answer:

x^2 + 6x + 9

Step-by-step explanation:

This is asking for (x+3) (x+3)

Using the FOIL method

(x * x) First, x times x

+ 3x Outside, x times 3

+ 3x Inside, x times 3

+ 9 Last, 3 times 3

Therefore, we have

(x*x) + 3x + 3x + 9

And simplified

x^2 + 6x + 9

Answer:

[tex]Time = 1.2\ hours[/tex]

Step-by-step explanation:

Given

[tex]Speed= 85\ miles/hour[/tex]

Required

Determine the time for 102 miles

In this case, we make use of Speed formula as follows:

[tex]Speed = \frac{Distance}{Time}[/tex]

This gives:

[tex]85 = \frac{102}{Time}[/tex]

Solve for Time

[tex]Time = \frac{102}{85}[/tex]

[tex]Time = 1.2\ hours[/tex]

Hence, the time needed is 1.2 hours

Hi there !

Volume (sphere) formula

V(s) = (4/3) × π × r³

we have two hemisheres

V(h) = (4/3) × π × r³ /2

= (2/3) × π × r³

V₁ = 2/3 ₓ π ₓ (12cm)³

= 2/3 ₓ π ₓ 1728cm³

= 1152π cm³

V₂ = 2/3 ₓ π ₓ (4cm)³

= 2/3 ₓ π ₓ 64cm³

= 128π/3 cm³

V = V₁ + V₂

= 1152π cm³ + 128π/3 cm³

= 3617.28 cm³ + 133.97 cm³

= 3751.25 cm³

Good luck !

Answer:

Since 6X2 + 6Y2 = 13 xy

-- 6X2 / XY + 6Y2/XY =13

---> 6 X/Y + 6 Y/X =13

    6a + 6/a =13

--->  6a2  + 6 =13a

---> 6a2 -13a +6 =0

--->  6a2 -9a - 4a +6 =0

---> (2a-3) (3a-2) =0

2a-3 = 0

a= 3/2  

So the Ratio will be = 3:2

Answer:

The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship.

Step-by-step explanation:

Answer:

The scale factor is a proportional relationship.   The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship. Enlargements have a scale factor greater than 1.  Reductions have a scale factor between 0 and 1. The proportion should be preserved.

Answer:

The function values of [tex]{q(2)}[/tex] is [tex]\bold{\dfrac{11}{4}}[/tex], [tex]q(0)[/tex] is UNDEFINED and [tex]q(-x)[/tex] is [tex]\bold{2+\dfrac{3}{x^2}}[/tex]

Step-by-step explanation:

Given,

[tex]q(t)=\dfrac{2t^2+3}{t^2}[/tex]

Part (a)

Find [tex]q(2)[/tex]

Put [tex]2[/tex] for [tex]t[/tex] for finding the value of the function [tex]q(2)[/tex].

Therefore,

[tex]\begin{aligned}q(2)&=\dfrac{2\times2^2+3}{2^2}\\&=\dfrac{8+3}{4}\\&=\dfrac{11}{4}\end{aligned}[/tex]

Part (b)

Find [tex]q(0)[/tex]

Put [tex]0[/tex] for [tex]t[/tex] for finding the value of the function [tex]q(0)[/tex].

[tex]\begin{aligned}q(0)&=\dfrac{2\times0^2+3}{0^2}\\&=\dfrac{3}{0}\\&=\infty\end{aligned}[/tex]

Part (c)

Find [tex]q(-x)[/tex]

Put [tex]-x[/tex] for [tex]t[/tex] for finding the value of the function [tex]q(-x)[/tex].

Therefore,

[tex]\begin{aligned}q(-x)&=\dfrac{2\times(-x)^2+3}{(-x)^2}\\&=\dfrac{2x^2+3}{x^2}\\&=2+\dfrac{3}{x^2}\end{aligned}[/tex]

Answer:

$15.9

Step-by-step explanation:

$397.5 = 25 hour

=> x dollars = 1 hour

=> 397.5 * 1 = 25 * x

=> 397.5 = 25x

=> 397.5/25 = 25x/25

=> 15.9 = x

So, for 1 hour he earns $15.9

The completed table is:

Eggs                                 Time (hours)

  3                                            75

 100                                        2500

  12                                          300

In a double number line diagram, equivalent ratios are represented by two parallel number lines.

Given that, the hen takes 25 hours to produce 1 egg.

1 egg = 25 hours

3 eggs = 25 × 3 hours

3 eggs = 75 hours

Similarly,

100 eggs = 2500 hours

and,

12 eggs = 300 hours

Hence, the completed table is:

Eggs                                 Time (hours)

  3                                            75

 100                                        2500

  12                                          300

Answer:

put a dot on point (2,-4) then go one to the right and one down hope this helps

Step-by-step explanation:

The equation of the line having a slope of -1, and passing through the point (2, -4) is x + y = - 2.

The equation of a line is the relation between the x-coordinates and y-coordinates of the points on the line, such that all (x, y) points, satisfies this equation.

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept of the line.

In the question, we are asked to graph the line with slope -1, and passing through the point (2, -4).

We know that, the slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept of the line.

Substituting m = -1, x = 2, and y = -4, in the equation, we get:

-4 = -1(2) + b,

or, b = -4 + 2 = -2.

Thus, the equation of the line is: y = -1(x) - 2,

or, x + y = -2.

Thus, the equation of the line having a slope of -1, and passing through the point (2, -4) is x + y = - 2.

The graph for the equation is attached.

Answer:

130 ± 1.82 inches i.e the range of the values is 128.18 inches to 131.82 inches.

Step-by-step explanation:

The range of values required here implies the values fall between the least and maximum values.

Since the values can vary by 1.4%, the range can be determined by:

1.4% of 130 = [tex]\frac{1.4}{100}[/tex] x 130

                  = 0.014 x 130

                  = 1.82

The addition or subtraction of 1.82 to/from 130 inches gives the required range.

i.e the range of allowable values = 130 ± 1.82 inches.

Thus,

130 - 1.82 = 128.18 inches

130 + 1.82 = 131.82 inches

The values falls between 128.18 inches to 131.82 inches.
