Answer: This is a problem of inverse variation, where the number of days that the food lasts is inversely proportional to the number of soldiers in the fort. We can use the formula:
d = k / s
where d is the number of days, s is the number of soldiers, and k is a constant of proportionality. We can find the value of k by using the initial information:
48 = k / 1500 k = 48 * 1500 k = 72000
Now we can use the information after 13 days to find the new number of soldiers. Let x be the number of soldiers who joined the fort. Then we have:
25 = 72000 / (1500 + x) 25 * (1500 + x) = 72000 37500 + 25x = 72000 25x = 34500 x = 1380
Answer: The number of soldiers who joined the fort after 13 days is 1380.

I don't know, I kind of wonder the same thing sometimes. But everyone understands things at a different rate, so that's why I'm here helping people by answering their questions and doing my best to explain how I got there.
thank you for the free points though :)

this is what happened to me
defective rate on the assembly line has gone up to 12% and the manager wants to know the
probability that a skid of 50 DVD players will contain at least 3 defective units.
a) Help Avery use the binomial distribution P(x)=, C.pqrs to answer this question
Answer:
0.9487
Step-by-step explanation:
a) The probability of having a defective product = p = 12% = 0.12
The probability of not having a defective product = q = 1 - p = 1 - 0.12 = 0.88
The number of DVD players = n = 50
X is the number of defective products.
The probability that a skid of 50 DVD players will contain at least 3 defective units = P(X ≥ 3) = 1 - P(X ≤ 2)
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
Using binomial:
P(X = 0) =
P(X = 1) =
P(X = 2) =
P(X ≤ 2)= 0.0017 + 0.0114 + 0.0382 = 0.0513
P(X ≥ 3) = 1 - P(X ≤ 2) = 1 - 0.0513 = 0.9487 = 94.87%

Answer:
The area of the soccer field where Ronald played his last game is 7,700 sq yd.
Step-by-step explanation:
From the question,
The area of the soccer field where Ronald played his last game was 69,300 square feet.
To determine the area, in square yards (sq yd), of the soccer field where Ronald played his last game, we will convert 69,300 square feet to square yards.
Also, from the question
There are 3 feet in a yard, that is, 3 feet = 1 yard
If 3 feet = 1 yard
∴ 3² square feet (ft²) will be equal to 1² square yard (yd²)
That is,
9 square feet = 1 square yard
Now,
If 9 square feet = 1 square yard
Then, 69,300 square feet will be
(69,300 square feet × 1 square yard) / 9 square feet = (69300/9 )square yards
= 7700 square yards (sq yd)
Hence, the area of the soccer field where Ronald played his last game is 7,700 sq yd.
The rungs are perpendicular to the other side.
The sides are perpendicular to each other.
The rungs are parallel to the sides.
