G A professor has two light bulbs in his garage. When both are burned out, they are replaced, and the next day starts with two w
Aneli [31]

Answer:

2/7 or 0.2857

Step-by-step explanation:

The expected time before the first bulb burns out (two bulbs working) is given by the inverse of the probability that a bulb will go out each day:

E_1 = \frac{1}{0.02}=50\ days

The expected time before the second bulb burns out (one bulb working), after the first bulb goes out, is given by the inverse of the probability that the second bulb will go out each day:

E_2 = \frac{1}{0.05}=20\ days

Therefore, the long-run fraction of time that there is exactly one bulb working is:

t=\frac{E_2}{E_1+E_2}=\frac{20}{20+50}\\t=\frac{2}{7}=0.2857

There is exactly one bulb working 2/7 or 0.2857 of the time.

How do you round 38,288 to the nearest 100
lys-0071 [83]

Consider the number 38,288

Now, we have to round this number to the nearest hundreds place.

The place value to the extreme right of the number is ones, then tens, hundreds, thousands, ten thousands and so on.

So, the digit at hundreds place = 2

Consider the digit to the right of the hundred place which is '8', which is greater than 5.

Therefore, we will add '1' to the digit at hundreds place.

Therefore, the number 38,288 rounded to nearest hundreds is 38,300.

A farm can harvest 120 pounds of carrots per acre of land. Each crate can hold 24 pounds of carrots. If a farmer owns 4.8 acres
Shtirlitz [24]

Answer:

The farmer needs 24 crates to hold the carrots.

Step-by-step explanation:

To determine how many crates the farmer needs to hold the carrots, knowing that his farm has 4.8 acres of land, where he can harvest 120 pounds per acre, and that each crates can hold up to 24 pounds of carrots, the following calculation must be performed:

(4.8 x 120) / 24 = X

576/24 = X

24 = X

Thus, the farmer needs 24 crates to hold the carrots.
