So option 1 is the correct answer ..

Answer:

350 lightbulbs

Step-by-step explanation:

First, we need to find the rate of lightbulbs that are inspected. This can be calculated as the division between the number of lightbulbs selected for inspection and the number of light bulbs produced. This is:

Rate = 7/400 =0.0175

That means that for every lightbulb produced, 0.0175 are inspected. Then if the factory produces 20000 light bulbs, the number of light bulbs inspected is:

20000*0.0175 = 350 lightbulbs

By solving for the unknown, the number of lightbulbs inspected can be determined as 350.

The quality control manager selects 7 lightbulbs out of 400 for inspection.

To find the number of lightbulbs inspected, we set up a proportion:

7 lightbulbs / 400 lightbulbs = x lightbulbs / 20000 lightbulbs

Solving for x gives:

x = (7/400) * 20000 = 350 lightbulbs inspected.

Answer:

12x=2pi*r

Step-by-step explanation:

2*22/7*r=12x

r=12x*7/44

r=21x/11

The radius of a circle is calculated by dividing the given circumference by 2π. When given circumferences of 6 inches, 6π inches, 12 inches, and 24π inches, the corresponding radii are approximately 0.955 inches, 3 inches, 1.91 inches, and 12 inches, respectively.

To find the radius of a circle given its circumference, we use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius. Since we are given the circumference, we can rearrange this formula to solve for the radius as follows: r = C / (2π).

Given the possible circumferences provided, we can calculate the radius for each.

For 6 inches: r = 6 / (2π) = 6 / (2 * 3.14) = 6 / 6.28 = approximately 0.955 inches

For 6π inches: r = 6π / (2π) = 6 / 2 = 3 inches

For 12 inches: r = 12 / (2π) = 12 / (2 * 3.14) = 12 / 6.28 = approximately 1.91 inches

For 24π inches: r = 24π / (2π) = 24 / 2 = 12 inches

Answer:

Step-by-step explanation:

Remember, a sphere is defined as a three-dimensional object where all points on its surface are equidistant form its center.

According to its definition, all point on the boundaries can be called a point on the sphere.

So, among the options, only point B is on the sphere, because J and S are inside.

Therefore, the right answer is Point B.

Answer:

Option B , D and E are correct.

Step-by-step explanation:

We set the denominator equal to zero to find the number to put in division box

So, if 3 is in the division box then the denominator will be

x-3 = 0 => x=3 is the root.

So, Option E is correct

2x^2-2x-12 ÷ x-3 = 2x+4 is correct.

because after division the result given is 2x+4 which is correct.

So, Option B is correct

x-3 is a factor of 2x^2-2x-12 because because when the term is divided we get the remainder 0.

So, Option D is correct

So, Option B,D and E are correct.

Answer:

(2.5, - 2)

Step-by-step explanation:

The solution to a system of equations given graphically is at the point of intersection of the 2 lines, that is

(2.5, - 2 ) ← point of intersection

Answer:

Option D is the correct answer.

Step-by-step explanation:

Refer the given figure showing the graph.

We can see the point of intersection is (2.5, -2).

Option D is the correct answer.

Alternatively:

2x + y = 3  ---------------------eqn 1

2x - 5y = 15  ---------------------eqn 2

eqn1 - eqn 2 gives

  2x + y - ( 2x - 5y) = 3 - 15

           6y = -12

             y = -2

Substituting in eqn 1

         2x - 2 = 3

            x = 2.5

Point of intersection is (2.5, -2).

Option D is the correct answer.

Answer:

x = 2

Step-by-step explanation:

Given 2 secants intersecting a circle from an external point, then

The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)

(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides

x² + 13x + 12 = x² + 9x + 20

Subtract x² + 9x from both sides

4x + 12 = 20 ( subtract 12 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Answer:

degrees apart in latitude: 91.22

degrees apart in longitude: 147.95

Step-by-step explanation:

Liverpool and Melbourne are two cities that are located very far away from each other. Liverpool is located in the northwestern part of England, while Melbourne is located in the southeastern part of Australia, so understandably their latitudes and longitudes are very different. In order to get to the distance in degrees between these two cities in latitude and longitude, we just simply need to sum the degrees of both of them and we will get to the result. The reason why simple summing will do the job is because they are on separate hemispheres, with Liverpool being on the Northern and Western Hemisphere, while Melbourne being on the Southern and Western Hemisphere.

Latitude distance:

53.41 + 37.81 = 91.22

Longitude distance:

2.99 + 144.96 = 147.95

Answer: 0.3 times

Step-by-step explanation:

Answer:

1.3 times

Step-by-step explanation:

The function [tex]f(x)=603(1.3)^{x}[/tex] represents the number of students enrolled at a university, x years after it was founded.

So the sequence will be formed to represent the number of students will be

f(1) = 603(1.3)

f(2) = 603(1.3)²

f(3) = 603(1.3)³

and so on.

Now the common ratio between second and first term will be

= [tex]\frac{(603)(1.3)^{2}}{603(1.3)}=1.3[/tex]

Therefore, second term of the sequence will be 1.3 times of the first term.

Answer will be - "Each year, the number of students will be 1.3 times the number the year before".

Answer:

The original price of the car can be written in percentage which is 100%. Because the price increased by 6%, therefore, the new price should be represented as:

100% + 6% = 106% = 1.06 (remember: not 0.06, that is how much the price increased, not 0.94 either, because the price increased, not decreased).

So the answer for the first question should be:

(a) new price = 1.06 × original price

from that, we can appy the answer above for the second question:

(b) new price: $33390

Option a: Line slants down.

Step-by-step explanation:

 It is important to remember that the equation of the line in Slope-Intercept form is the following:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

The slope of a line can be positive (The line slopes upwards to the right), negative (The line slopes downwards to the right), zero (Horizontal line), or undefined (Vertical line).

Therefore, the statement that best describes a line in a slope-intercept form when the coeficient of the x-term (The slope) is negative is: "Line slants down".

That is true.

The diameter is a line that passes through the center of a circle.

Answer: True is the answer

To find the volume of the new sphere, calculate the volume of the original sphere and then multiply it by the scale factor cubed. Convert the volume from cubic centimeters to cubic inches using the conversion factor: 1 cm³ = 0.0610237 in³. The approximate volume of the new sphere in cubic inches is 255.3 in³.

To find the volume of the new sphere, we need to first find the volume of the original sphere and then multiply it by the scale factor cubed. The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius.

Given that the radius of the original sphere is 5 cm, we can calculate its volume using the formula:

V1 = (4/3)π(5 cm)³ ≈ 523.6 cm³.

Next, we can calculate the volume of the new sphere by multiplying the volume of the original sphere by the scale factor cubed:

V2 = V1 × (2)³ = 523.6 cm³ × 8 ≈ 4188.8 cm³.

Finally, to convert the volume from cubic centimeters to cubic inches, we need to use the conversion factor: 1 cm³ = 0.0610237 in³. Therefore, the approximate volume of the new sphere in cubic inches is:

V2 ≈ 4188.8 cm³ × 0.0610237 in³/cm³ ≈ 255.3 in³.
