Answer: 1.55630250

Step-by-step explanation:

g(x) = 2 log (2x)

For g(3) put 3 in place of x

g(3)=2 log (2*3)

      =2log(6)

g(3)      =1.55630250

Answer:

y = 2*x - 4

Step-by-step explanation:

The general equation for a line is:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this case, we know that the line passes through (4, 4) and the y-intercept is -4.

Then:

b = -4

So our line is something like:

y = a*x - 4

Now, we know that the line passes through (4, 4), which means that when x = 4, y = 4.

If we replace these values in the equation, we get:

4 = a*4 - 4

Now we can solve this for a.

4 = a*4 - 4

4 + 4 = a*4

8 = a*4

8/4 = a = 2

Then the equation for the line is:

y = 2*x - 4

Answer:

1. 18.84 2. 172.2 3.219.8

Step-by-step explanation:

1.   formula: v=(r*pi)*h

v=(6^2*3.14)*4

v=(36*3.14)*4

v=113.04*4

v=452.16

2. formula: v=(r*pi)*h

because you were given the diameter for number 2 you would have to do 10/2 to find the radius. so 5

now plug it into you're equation.

v=(5^2*3.14)*11

v=(25*3.14)*11

v=78.5*11

v=863.5

3. formula: v=(r*pi)*h

v=(7^2*3.14)*10

v=(49*3.14)*10

v=153.86*10

v=153.86

Answer:

The cubic regression that fits the given set of points is [tex]y = 2\cdot x^{3}-2\cdot x^{2} -3\cdot x + 7[/tex].

Step-by-step explanation:

Let the cubic regression be represented by the following third order polynomial:

[tex]y = a\cdot x^{3}+b\cdot x^{2}+c\cdot x + d[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]a,b,c,d[/tex] - Coefficients.

By Algebra, we can determine analytically the values of all coefficients by knowing four distinct points. If we know that [tex](x_{1}, y_{1}) = (1,4)[/tex], [tex](x_{2},y_{2}) = (2,9)[/tex], [tex](x_{3}, y_{3}) = (3, 34)[/tex] and [tex](x_{4}, y_{4}) = (-2, -11)[/tex], then the system of linear equations is:

[tex]a+b+c+d = 4[/tex] (1)

[tex]8\cdot a + 4\cdot b + 2\cdot c + d = 9[/tex] (2)

[tex]27\cdot a + 9\cdot b + 3\cdot c + d = 34[/tex] (3)

[tex]-8\cdot a + 4\cdot b -2\cdot c + d = -11[/tex] (4)

The solution of the system of linear equations is: [tex]a = 2[/tex], [tex]b = -2[/tex], [tex]c = -3[/tex], [tex]d = 7[/tex]

The cubic regression that fits the given set of points is [tex]y = 2\cdot x^{3}-2\cdot x^{2} -3\cdot x + 7[/tex].

The answer for the right triangle is 5

Answer:

x = -8, y = -7

Step-by-step explanation:

=> x = 6 + 2y

substitute x = 6 + 2y into the equation 3x - 5y = 11 to solve for y:

=> 3(6 + 2y) - 5y = 11

=> 18 + 6y -5y = 11

=> y = -7

substitute y = -7 into the equation x - 2y = 6 to solve for x:

=> x - 2(-7) = 6

=> x +14 = 6

=> x = -8

Step-by-step explanation:

The quadratic equations that would be used when solving the given information is 4x² + 72x = 20 , Option B is the correct answer.

Area is the space occupied by any surface ,It is measure in square units of length.

It is given that

A photographer needs a frame for a 16 x 20 inch picture

total area is 340 sq. in

width of the frame =?

Let width of the frame be x

The frame is in the shape of a Rectangle

Side of the frame =  ( 16+2x) and (20 +2x)

Area of a frame = Total Area -  Area of the picture

Total Area =  ( 16+2x) (20 +2x)

( 16+2x) (20 +2x) = 340

320 + 72x +4x² = 340

72x +4x²= 20

4x² + 72x = 20

The quadratic equations that would be used when solving the given information is 4x² + 72x = 20 , Option B is the correct answer.

Answer:

We Do not have enough evidence

Step-by-step explanation:

H0 : σ² ≤ 1.1

H0 : σ² > 1.1

The test statistic (X²) :

χ² = [(n - 1) × s²] ÷ σ²

n = sample size, = 20

s² = 1.6

σ² = 1.1

α = 0.01

χ² = (19 * 1.6) / 1.1

χ² = 27.64

Pvalue :

Using the Pvalue from Chisquare score calculator ; χ² = 27.64 ; df = 19

Pvalue = 0.091

If Pvalue < α ; Reject H0

0.091 > 0.01

Hence, Pvalue > α ; Thus we fail to reject H0.

We thus conclude that, we do not have enough evidence to support the claim that her standard deviation is greater than the target.
