l=length

w= width

h=height

Answer:

Step-by-step explanation:

Answer:

405 in^2

Step-by-step explanation:

Given data

Height= 27in

Circumference= 47.1 in

let us find the radius and the diameter of the base of the cylinder

from

C=2πr

47.1= 2*3.142*r

47.1= 6.284r

r= 47.1/6.284

r= 7.5 in

Diameter= 2r

D= 7.5*2

D= 15in

Hence the area of the cross-section

=H*D

=27*15

=405 in^2

Answer:

(3x^2) - 8x

Step-by-step explanation:

A = length x width

A = x(3x-8) *Distribute*

The required possible 90% confidence interval for the mean battery life is (10.95, 19.05) hours.

Statistic is the study of mathematics that deals with relations between comprehensive data.

Here,
Assuming that the sample means and sample standard deviation were calculated from the data, a possible 90% confidence interval for the population means battery life can be calculated using the t-distribution.

For example, if the sample mean is 15 hours and the sample standard deviation is 3 hours, with a sample size of 6 and a 90% confidence level, the t-interval would be:

t-interval = sample mean ± t*(sample standard deviation / √(sample size))

where t is the t-value with (sample size - 1) degrees of freedom and a 90% confidence level.

Using a t-table, the t-value for 5 degrees of freedom and a 90% confidence level is approximately 2.571. Plugging in the values, we get:

t-interval = 15 ± 2.571*(3 / √(6))

t-interval ≈ (10.95, 19.05)

Therefore, a possible 90% confidence interval for the mean battery life is (10.95, 19.05) hours.

........................

Answer:

(10111)2 = (23)10

Step by step solution

Step 1: Write down the binary number:

10111

Step 2: Multiply each digit of the binary number by the corresponding power of two:

1x24 + 0x23 + 1x22 + 1x21 + 1x20

Step 3: Solve the powers:

1x16 + 0x8 + 1x4 + 1x2 + 1x1 = 16 + 0 + 4 + 2 + 1

Step 4: Add up the numbers written above:

16 + 0 + 4 + 2 + 1 = 23.

So, 23 is the decimal equivalent of the binary number 10111.

Given:

Line KJ represents a proportional relationship.

Point K lies at (12,14).

To find:

The ordered pair of the coordinates of point J.

Solution:

If y is proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

It means, the ratios of y to x for all the point in a proportional relationship are same.

Line KJ represents a proportional relationship. Point K lies at (12,14).

So, the constant of proportionality is:

[tex]k=\dfrac{14}{12}[/tex]

[tex]k=\dfrac{7}{6}[/tex]

Similarly, find the ratio of y to x for all given points.

In option a,

[tex]\dfrac{3.5}{3}=\dfrac{3.5\times 2}{3\times 2}[/tex]

[tex]\dfrac{3.5}{3}=\dfrac{7}{6}[/tex]

In option b,

[tex]\dfrac{15}{17.5}=\dfrac{15\times 2}{17.5\times 2}[/tex]

[tex]\dfrac{15}{17.5}=\dfrac{30}{35}[/tex]

[tex]\dfrac{15}{17.5}=\dfrac{6}{7}[/tex]

In option c,

[tex]\dfrac{0}{2}=0[/tex]

In option d,

[tex]\dfrac{3}{3.5}=\dfrac{3\times 2}{3.5\times 2}[/tex]

[tex]\dfrac{3}{3.5}=\dfrac{6}{7}[/tex]

The ratio of y to x of point (3,3.5) is equal to the ratio of given point K(12,14). So, the coordinates of point J are (3,3.5).

Therefore, the correct option is A.

Answer:

6.25x + 2d

Step-by-step explanation:

6.25x = The Hourly Pay

2d = Bonus Pay

Add them to find the total:

6.25x + 2d

The amount of money that he makes during the first week will be C = 6.75x + 2d.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

You have a part-time job at a restaurant.

You get paid $6.75 the hour and get a daily bonus of $2 for each customer that orders dessert.

If you work x hours per week and there are d customers that order dessert per week.

Let C be the amount of money that he makes during the first week.

C = 6.75x + 2d

The amount of money that he makes during the first week will be C = 6.75x + 2d.

I think its.

The coterminal angles of ( 7π/8 ) are ( 9π/8 ) , ( -9π/8 ) and ( 23π/8 )

Angles with the same starting side and terminal side are said to be coterminal angles. Depending on whether the given angle is in degrees or radians, finding coterminal angles is as easy as adding or subtracting 360° or 2 to each angle. Coterminal angles can be found in an unlimited number of ways.

To find the coterminal angles of angle θ

The measure of coterminal angle is θ ± 360n,  if θ is measured in degrees.

And , measure of coterminal angle isθ ± 2πn,  if θ is measured in radians.

Given data ,

Let the angle be represented as θ

Now , the value of θ = ( 7π/8 )

On simplifying the equation , we get

To find the coterminal angles of angle θ

θ ± 2πn,  if θ is measured in radians.

Substituting the values in the equation , we get

x₁ = ( 7π/8 ) + 2π

x₁ = ( 23π/8 )

And ,

x₂ = 2π - ( 7π/8 )

x₂ = ( 9π/8 )

And ,

x₃ = ( 7π/8 ) - 2π

x₃ = ( -9π/8 )

Hence , the coterminal angles are ( 9π/8 ) , ( -9π/8 ) and ( 23π/8 )
