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: 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".

Step-by-step explanation:

The average rate of change over the entire slide is [tex]\( \frac{1}{10} \)[/tex] feet per foot.

To find the average rate of change over the entire slide, we need to calculate the change in height divided by the change in distance over the entire slide.

Let's denote:

- [tex]\( h_1 \)[/tex] as the initial height (when x = 0),

- [tex]\( h_2 \)[/tex] as the final height (when x = 20).

Given that the height of the slide is 2 feet when ( x = 20 ), we have:

[tex]\[ h_2 = 2 \, \text{feet} \][/tex]

We also know that the height of the slide is 0 feet when ( x = 0 ), so:

[tex]\[ h_1 = 0 \, \text{feet} \][/tex]

Now, the change in height ([tex]\( \Delta h \)[/tex]) over the entire slide is:

[tex]\[ \Delta h = h_2 - h_1 = 2 \, \text{feet} - 0 \, \text{feet} = 2 \, \text{feet} \][/tex]

The change in distance ([tex]\( \Delta x \)[/tex]) over the entire slide is simply the distance traveled, which is:

[tex]\[ \Delta x = 20 \, \text{feet} \][/tex]

The average rate of change over the entire slide ([tex]\( \text{Avg ROC} \)[/tex]) is then:

[tex]\[ \text{Avg ROC} = \frac{\Delta h}{\Delta x} \][/tex]

[tex]\[ \text{Avg ROC} = \frac{2 \, \text{feet}}{20 \, \text{feet}} \][/tex]

[tex]\[ \text{Avg ROC} = \frac{1}{10} \][/tex]

The average rate of change of the slide height is calculated as 0.1 feet per foot, indicating that the height increases by 0.1 feet for every foot along the slide.

Step by step calculation:

The average rate of change of a function over an interval is calculated using the formula:

       Average Rate of Change = (2 - 0) / (20 - 0) = 2 / 20 = 0.1 feet per foot

This means the height increases by 0.1 feet for every foot traveled along the length of the slide.

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.

To find the number of 5-digit numbers that can be formed using the digits 0-6 without repetition, we use permutations. The answer is 5,040.

To find the number of 5-digit numbers that can be formed using the digits 0, 1, 2, 3, 4, 5, 6 (without repetition), we need to use the concept of permutations.

Since repetition is not allowed, for the first digit, we have 7 choices (0 cannot be the first digit). For the second digit, we have 6 choices (since one digit has been used). For the third digit, we have 5 choices (since two digits have been used), and so on.

Therefore, the number of 5-digit numbers that can be formed is 7 x 6 x 5 x 4 x 3 = 5,040.

Answer:

Option C is correct.

Step-by-step explanation:

We need to find the pattern as the exponent decreases.

the first value in the table is 125.

if we divide 125 by 5 i.e 125/5 we get 25

the next value in the table is 25

if we divide 25 by 5 i.e 25/5 we get 5

the next value in the table is 5

if we divide 5 by 5 i.e 5/5 we get 1

the next value in the table is 1

if we divide 1 by 5 i.e 1/5 we get 1/5

the next value in the table is 1/5

if we divide 1/5 by 5 i.e 1/5*5 we get 1/25

the next value in the table is 1/25

So, the pattern is if we divide the previous value by 5 we get the next value in the table.

So, Option C is correct.

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
