The size of the square that should be cut out of each corner to get a bin with maximum volume is 8 inches.

Let's assume that we cut out a square of side length x from each corner of the plastic piece. After cutting out the squares, the remaining length of the rectangle will be 32-2x inches, and the remaining width will be 42-2x inches.

The height of the bin will be x inches, since we fold up the flaps on each side.

The volume of the bin will be

V = (length) × (width) × (height)

= (32-2x) × (42-2x) × x

To find the value of x that maximizes the volume, we need to take the derivative of V with respect to x, set it equal to zero, and solve for x

dV/dx = 4x^3 - 148x^2 + 1344x

= 4x(x^2 - 37x + 336)

Setting this expression equal to zero and solving for x, we get

x = 8 inches, x = 21 inches, or x = 0 inches

However, x = 0 inches would result in no bin being formed.

To determine which value of x maximizes the volume, we need to evaluate V at each critical point

V(8) = 2688 cubic inches

V(21) = 1176 cubic inches

Therefore, the size of the square that should be cut out of each corner is 8 inches

The mean commuting time for the particular train, assuming a uniform distribution between 20 and 50 minutes, is 35 minutes. This means that, on average, commuters can expect their commuting time to be around 35 minutes.

To calculate the mean commuting time, we need to find the average value of the uniformly distributed commuting time between 20 and 50 minutes.

In a uniform distribution, the probability density function (PDF) is constant within the range of the distribution. Since the distribution is uniform between 20 and 50 minutes, the PDF is constant over that interval.

The mean of a uniform distribution can be calculated using the formula:

Mean = (a + b) / 2

where 'a' is the lower limit of the distribution (20 minutes) and 'b' is the upper limit (50 minutes).

Plugging in the values into the formula, we get:

Mean = (20 + 50) / 2 = 70 / 2 = 35 minutes

The calculation is straightforward because in a uniform distribution, the mean is simply the average of the minimum and maximum values of the distribution.

In this case, the commuting time is equally likely to be any value between 20 and 50 minutes. So, on average, commuters can expect a mean commuting time of 35 minutes.

It is important to note that the mean represents the average value and may not necessarily reflect the most frequently occurring commuting time. In this case, there is an equal likelihood of any time within the given range.

Never second guess yourself

Step-by-step explanation:

The total electric force on the 7.00−μC charge is 0.872 N at an angle of 330°.

The force exerted on the 7.00−μC charge by the 2.00−μC charge is

F₁​ ​= \(k_{e}\)q₁q₂​​/r₂ r^

= [(8.99×10⁹N.m²/C²)(7.00×10^−6C)(2.00×10^−6C) ×(cos60°i^+sin60°j^​)]/ (0.500m)²

F₁ ​= (0.252i^+0.436j^​)N

Similarly, the force on the 7.00μC charge by the −4.00−μC charge is

F₂​ ​= \(k_{e}\)q₁​q₃/​r² ​​r^

= [(8.99×10⁹N.m²/C²)(7.00×10^−6C)(−4.00×10^−6C)​×(cos60°i^−sin60°j^​)]/(0.500m)²

F₂​ ​=(0.503i^−0.872j^​)N

Hence, the total force on the charge 7.00−μC  is

F = F₁​​+F₂​

​=(0.755i^−0.436j^​)N

We can also note the total force as:

Step-by-step explanation:

Miko bought 4.5 pounds of regular carrots.Given that regular carrots cost $0.88 per pound, and baby carrots cost $1.48 per pound.

Miko buys three more pounds of regular carrots than baby carrots.

Miko pays $6.18 for carrots.

We are to find how many pounds of regular carrots did Miko buy.

Let us assume that Miko bought x pounds of baby carrots.

Then, the number of pounds of regular carrots bought will be (x + 3).

We know that the cost of baby carrots per pound is $1.48. So, the cost of x pounds of baby carrots is $1.48 × x.

We also know that the cost of regular carrots per pound is $0.88.

So, the cost of (x + 3) pounds of regular carrots is $0.88(x + 3).

Miko paid a total of $6.18 for carrots.

Hence, we can form the equation:

\(1.48x+ $0.88(x + 3)\)

\(= $6.18$1.48x + $0.88x + $2.64\)

\(= $6.18$2.36x\)

\(= $6.18 - $2.64\)

\(= $3.54x\)

\(= $3.54/$2.36x\)

\(= 1.5\)

Hence, Miko bought 1.5 pounds of baby carrots.

Therefore, the number of pounds of regular carrots bought will be (x + 3) = (1.5 + 3) = 4.5 pounds.

Answer: Miko bought 4.5 pounds of regular carrots.

To solve this problem, we can use the Poisson distribution, which models the number of events that occur in a fixed period of time, given the average rate of occurrence.

a. To find the probability that at most 425 people are struck by lightning in a year, we can use the Poisson distribution with a mean of 400. The formula for the Poisson distribution is:
P(X ≤ k) = e^-λ ∑_(i=0)^k (λ^i/i!)
where X is the random variable (the number of people struck by lightning in a year), λ is the mean (400), and k is the maximum number of people we're interested in (425). Plugging in the values, we get:
P(X ≤ 425) = e^-400 ∑_(i=0)^425 (400^i/i!) = 0.8855
So the probability that at most 425 people are struck by lightning in a year is 0.8855, or about 88.55%.
b. To find the probability that at least 375 people are struck by lightning in a year, we can use the complement rule: the probability of an event happening is 1 minus the probability of the event not happening. So in this case, we want to find the probability that fewer than 375 people are struck by lightning, and subtract that from 1 to get the probability of at least 375 people being struck.
P(X ≥ 375) = 1 - P(X < 375) = 1 - e^-400 ∑_(i=0)^374 (400^i/i!) = 0.9369
So the probability that at least 375 people are struck by lightning in a year is 0.9369, or about 93.69%.
It's important to note that these probabilities are based on the assumption that the number of people struck by lightning in a year follows a Poisson distribution with a mean of 400. This may not be a perfect model, but it's a reasonable approximation based on the available data. Additionally, the chances of being struck by lightning are still relatively low - even at the high end of our estimates, only about 0.1% of the US population would be affected.

Based on the given information of 400 people being struck by lightning in the United States on average each year, we can calculate the probabilities for the scenarios you mentioned.
a. The probability that at most 425 people are struck by lightning in a year:
To calculate this, we'll need to know the distribution of people being struck by lightning, which isn't provided. However, let's assume it follows a normal distribution with a mean of 400 and some standard deviation. In this case, we would calculate the z-score for 425 people and find the corresponding probability from the z-table. Unfortunately, without the standard deviation, we cannot compute the exact probability.
b. The probability that at least 375 people are struck by lightning in a year:
Similarly, to calculate this probability, we'd need the standard deviation to find the z-score for 375 people and then find the corresponding probability from the z-table. Again, without the standard deviation, we cannot compute the exact probability.
In conclusion, without knowing the standard deviation or the distribution of people being struck by lightning, we cannot provide a precise probability for the given scenarios.

Answer:

if 5 people =1 hour. which is 60 minutes.

so 8people.52 minutes ...it wont take hours .since an hour is 60 min.

Answer:

Step-by-step explanation:

Let's solve:

\( \mathsf {people \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: time( \: in \: minutes) }\)

\( \mathsf{5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 1 hour = 60 minutes}\)

Here, Let 8 people take x minutes to complete the work.

Since, the number of people and their working minutes are indirect proportional. So,

Here, the ratio of people = 5 : 8

The ratio of minutes = 60 : x

So,

\( \mathsf{ \frac{5}{8} = \frac{x}{60} }\)

Apply cross product property

⇒\( \mathsf{8x = 60 \times 5}\)

Multiply the numbers

⇒\( \mathsf{8x = 300}\)

Divide both sides of the equation by 8

⇒\( \mathsf {\frac{8x}{8} = \frac{300}{8} }\)

Calculate

⇒\( \mathsf{x = 37.5 \: minutes}\)

The equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

What is the equation of the line?

To find the equation of a line that passes through two given points, we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, and m is the slope of the line.

The slope of the line can be found by using the two points:

m = (y2 - y1) / (x2 - x1)

So,

m = (2 - 4) / (-2 - (-6)) = -2/4 = -1/2

We know that the line passes through the point (-6,4) so we can substitute the values into the equation:

y - 4 = -1/2(x + 6)

Hence, the equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)
