Step-by-step explanation:

The probability of randomly selecting two good bulbs is equal to 0.665.

So, we have a set of 32 bulbs, such that 26 are good and 6 are burned.

The probability of randomly selecting one good bulb is equal to the quotient between the number of good bulbs and the total number of bulbs.

It gives:

P = 26/32

Now, for the next bulb, the probability is computed in the same way, but now there are 25 good bulbs and 31 in total, so the probability is:

P' = 25/31

The joint probability is given by the product between the two individual probabilities:

p = (26/32)*(25/31) = 0.655

Answer:

5 hours per lawn

Step-by-step explanation:

15 hours divided by 3 lawns brings you to 5 hours per lawn.

The rate at which Lauren mows lawns is 5 hours per lawn, which means on average, it takes her 5 hours to mow one lawn.

The question is asking us to find out how long, on average, it takes Lauren to mow one lawn given that she can mow 3 lawns in 15 hours. This is a classic problem of rate, specifically a rate of work. The formula we use for rate is simply: Rate = Total Work / Total Time. Here, the total work would be the 3 lawns that she mowed, and the total time would be the 15 hours. So, we divide 15 (total hours) by 3 (total lawns) to get the rate of mowing:

Rate = 15 / 3 = 5 hours per lawn.

This means that, on average, it takes Lauren 5 hours to mow a single lawn.

Answer:

Part B (solution): For 0.42... (with the two repeating forever), we need to break up the decimal into the part that does not repeat and the part that repeats.

For the part that does not repeat, pretend that the repeating part is not there (so you have 0.4). Then think about place value. The non-repeating part of this decimal (0.4) is 4 tenths, so write that as a fraction: 4/10.

For the part that repeats, pretend the part that does not repeat is not there (so you have 0.2....). Use the rule of 9s, which tells you to put the repeating part (2) over a nine for every place value that is repeating. In this case there is only one repeating place value (again, 2), so we have 2/9. However, since we skipped a place value (the 4 in our given problem), we need to multiply that place value (in this case 1/10) by 2/9, which is 2/90. Finally, we need to add that to 4/10. Make sure your answer is simplified. Click HERE for help on Question 1.

Part C (solution): For 0.42... (with the four AND two repeating forever), use the rule of 9s. The rule of 9s tells you to put the repeating part (42) over a nine for every place value that is repeating. In this case there is two repeating place values, so we have 42/99.

The fraction representation of 0.¯42 in simplest form is 14/33.

To express the repeating decimal 0.¯42 as a fraction in simplest form, we can use a mathematical technique.

Let's represent the repeating decimal as x = 0.¯42.

To remove the decimal part, we can multiply both sides of the equation by 100 (to move the decimal point two places to the right):

100x = 42.¯42.

Next, we subtract the original equation from the one multiplied by 100 to eliminate the repeating part:

100x - x = 42.¯42 - 0.¯42.

Simplifying both sides gives:

99x = 42.

Now, we can divide both sides of the equation by 99 to isolate x:

x = 42 / 99.

To simplify the fraction 42/99, we can find the greatest common divisor (GCD) of 42 and 99 and divide both the numerator and the denominator by it.

The GCD of 42 and 99 is 3:

42 = 3 x 14,

99 = 3 x 33.

Dividing both sides by 3 gives:

42 / 99 = (3 x 14) / (3 x 33) = 14 / 33.

Therefore, the fraction representation of 0.¯42 in simplest form is 14/33.

Final answer:

The possible dimensions for a rectangular prism with a volume of 72 cubic meters are options B (3 m x 4 m x 6 m), D (9 m x 8 m x 1 m), and E (12 m x 2 m x 3 m), as their product of dimensions equals 72 cubic meters.

Explanation:

The question presents a schoolwork problem related to finding the possible dimensions of a rectangular prism with a given volume. According to the formula for volume, V = B x h, where V stands for volume, B is the area of the base, and h is the height. For a prism to have a volume of 72 cubic meters, the product of its dimensions (length x width x height) must equal 72.

For option A (2 m x 6 m x 7 m), the volume is 2 x 6 x 7 = 84 cubic meters, which is not equal to 72.

For option B (3 m x 4 m x 6 m), the volume is 3 x 4 x 6 = 72 cubic meters, which is correct.

For option C (3 m x 8 m x 4 m), the volume is 3 x 8 x 4 = 96 cubic meters, which is not equal to 72.

For option D (9 m x 8 m x 1 m), the volume is 9 x 8 x 1 = 72 cubic meters, which is also correct.

For option E (12 m x 2 m x 3 m), the volume is 12 x 2 x 3 = 72 cubic meters, which is another correct possibility.

Therefore, the possible dimensions for the rectangular prism with a volume of 72 cubic meters are represented by options B, D, and E.

The area of the given rectangle is 48 square units.

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

We have the graph from which we can write

width of rectangle = 8 unit

Length of rectangle= 6 unit

So, the area of rectangle

= lw

= 8 x 6

= 48 unit²

Final answer:

The probability of first picking a green marble, replacing it, and then picking a blue marble from a bag containing 5 red, 4 green, and 3 blue marbles is 1/12.

Explanation:

The question is about calculating the probability of selecting a green marble and then a blue marble from a bag with a replacement in between the picks. The process involves two independent events since the green marble is replaced before picking the blue marble.

To calculate the probability of picking a green marble first, we consider the total number of marbles and the number of green marbles. Given there are 5 red, 4 green, and 3 blue marbles, the total number of marbles is 5+4+3=12. The probability of picking a green marble is thus 4/12 or 1/3. Because we replace the green marble, the bag's contents remain the same for the second pick.

The probability of picking a blue marble after replacing the green marble is therefore based on the same total of 12 marbles. The probability is 3/12 or 1/4. Now, since these are independent events, we multiply the two probabilities together to get the overall probability of both events happening in sequence: (1/3) * (1/4) = 1/12.

In summary, the probability of first picking a green marble, replacing it, and then picking a blue marble is 1/12.

Final answer:

The probability of randomly picking a green marble, replacing it, and then randomly picking a blue marble is 1/12.

Explanation:

To find the probability of randomly picking a green marble, replacing it, and then randomly picking a blue marble, we need to first calculate the individual probabilities.

The bag initially contains 5 red, 4 green, and 3 blue marbles. The probability of picking a green marble is 4/12, since there are 4 green marbles out of a total of 12 marbles.

Since the first marble is replaced, the bag still contains the same number of green marbles, so the probability of picking a blue marble on the second draw is also 3/12, since there are 3 blue marbles left out of 12 marbles.

To find the probability of both events happening, we multiply the individual probabilities: (4/12) * (3/12) = 1/12.

Answer: The height of the rocket after 9 seconds is 2068.1 meters.

The height of the rocket when it initially launched is 269 meters.

Step-by-step explanation:

Given, NASA launches a rocket at [tex]t=0[/tex] seconds.

Its height, in meters above sea-level, in terms of time is given by [tex]h=-4.9t^2+244t+269.[/tex]

To find, the height of the rocket after 9 seconds put t=9, we get

[tex]h=-4.9(9)^2+244(9)+269\\\\=-4.9(81)+2196+269\\\\=-396.9+2465\\\\=2068.1[/tex]

Hence, the height of the rocket after 9 seconds is 2068.1 meters.

To find, the height of the rocket when it initially launched put t=0, we get

[tex]h=-4.9(0)^2+244(0)+269\\\\=0+0+269\\\\=269[/tex]

Hence, the height of the rocket when it initially launched is 269 meters.

The correct answer of Resale value is :

The Ruiz family's laptop has the greater initial resale value.

The Ruiz family's laptop will have a higher resale value than the Sawyer family's laptop after 4 years.

The resale value of the Sawyer family's laptop decreases at a faster average rate than the resale value of the Ruiz family's laptop.

Based on the table, the Ruiz family's laptop has the greater initial resale value. They bought it for $640, while the Sawyer family bought their laptop for $620.

To compare the resale values of the two laptops after 4 years, we can evaluate the functions g(4) and A(4).

[tex]g(4) = 640 \times0.85^4 = 360.78[/tex]

[tex]A(4) = 620 \times 0.85^4 = 343.65[/tex]

Therefore, the Ruiz family's laptop will have a higher resale value than the Sawyer family's laptop after 4 years.

To compare the average rates of decrease of the resale values of the two laptops, we can calculate the following:

Average rate of decrease of the Ruiz family's laptop: (640 - 360.78) / 4 = 70.63

Average rate of decrease of the Sawyer family's laptop: (620 - 343.65) / 4 = 68.35

Conclusion:

The Ruiz family's laptop has the greater initial resale value.

The Ruiz family's laptop will have a higher resale value than the Sawyer family's laptop after 4 years.

The resale value of the Sawyer family's laptop decreases at a faster average rate than the resale value of the Ruiz family's laptop.
