If twice a number is at most 24, find the number.

Answer: The input force (effort) on the rope is 20 N.

Step-by-step explanation:

In a frictionless pulley system, the tension in the rope is constant throughout. Therefore, the force applied to the rope on one side of the pulley system is equal to the force exerted on the other side of the system.

In this problem, we know that the weight of the block is 20 N. This means that there is a force of 20 N acting downwards on one side of the pulley system.

Since the pulley system is frictionless, the tension in the rope is also 20 N. Therefore, the force applied to the rope on the other side of the pulley system (i.e., the input force or effort) must also be 20 N in order to balance the weight of the block.

So the input force (effort) on the rope is also 20 N.

From the given information provided, the number of people having brown eyes in town is 180.

If the probability that a person in the town has brown eyes is 2/5, then we can expect that 2 out of every 5 people have brown eyes.

To find the number of people in the survey who would be expected to have brown eyes, we can use the following proportion:

(2/5) = (x/450)

where x is the number of people expected to have brown eyes.

Solving for x, we can cross-multiply:

5x = 2 × 450

5x = 900

x = 180

Therefore, the expected number of people in the survey who would have brown eyes is 180.

Suppose sat writing scores are normally distributed with a mean of 497 and a standard deviation of 114. A university plans to admit students whose scores are in the top 30%, the minimum score required for admission is 434

Given information:

Let X be the random variable which represents the SAT writing scores. Then X ~ N(497, 114)Now we have to find the minimum score required for admission. We can solve the problem using the standard normal distribution table. Here we need to find the z-score.

The formula for z-score is given below:z = (X - μ) / σ z-score corresponding to the probability (p) can be calculated as:z = ZpWhere Zp is the standard normal variable, which gives the area to the left of the z-score. So, Zp = InvNorm(0.30) = - 0.524For the top 30% of the scores, we have Zp = -0.524. Now the z-score is known. So we can calculate the minimum score required for admission as :X = μ + z * σ = 497 + (-0.524) * 114 = 433.584 ≈ 434The minimum score required for admission is 434.

What is mass ?

Mass is a physical property of matter, which refers to the amount of substance present in an object. It is typically measured in units of grams or kilograms, and can be thought of as a measure of the object's inertia or resistance to acceleration. Mass is often used interchangeably with weight in everyday language, but they are technically different concepts. Weight is a measure of the force of gravity acting on an object, and varies depending on the object's location in the gravitational field.

According to the question:
First, we need to find the mass of the bouncy balls in the box by subtracting the mass of the box only from the mass of the box and bouncy balls.

Mass of bouncy balls in box = Mass of box and bouncy balls - Mass of box only

Mass of bouncy balls in box = 17,342 - 429

Mass of bouncy balls in box = 16,913 grams

Next, we need to find the mass of one bouncy ball by dividing the mass of 45 balls by 45.

Mass of one bouncy ball = Mass of 45 balls / 45

Mass of one bouncy ball = 505 / 45

Mass of one bouncy ball = 11.222 grams

Finally, we can estimate the number of bouncy balls in the box by dividing the mass of the bouncy balls in the box by the mass of one bouncy ball.

Number of bouncy balls in box = Mass of bouncy balls in box / Mass of one bouncy ball

Number of bouncy balls in box = 16,913 / 11.222

Number of bouncy balls in box ≈ 1506

Therefore, there are approximately 1506 bouncy balls in the box.

The dimensions of the can of greatest volume that can be made with 150 square inches of tin are a radius of approximately 5.78 inches and a height of approximately 3.85 inches.

The dimensions of the soup can of greatest volume that can be made with 150 square inches of tin are given by the formula [tex]V = \pi r^2h[/tex], where V is the volume of the can, r is the radius of the base, and h is the height of the can. We can solve for the radius and height of the can using the given information.

Let the radius of the base be r and the height of the can be h. Then, the surface area of the can is given by the formula [tex]A = 2\pi rh + 2 \pi r^2[/tex]. We are given that the surface area of the can is 150 square inches, so we can write the equation [tex]2 \pi rh + 2 \pi r^2 = 150[/tex]. We need to find the dimensions of the can that maximize its volume, V. To do this, we can use the formula for the derivative of V with respect to r, which is [tex]dV/dr = 2 \pi rh + \pi r^2 dh/dr[/tex].

Setting this equal to zero and solving for h, we get [tex]h = -2r/3[/tex]. Substituting this into the equation for A, we get the equation [tex]2 \pi r(-2r/3) + 2 \pi r^2 = 150[/tex], which simplifies to [tex]-4 \pi r^2/3 + 2 \pi r^2 = 150[/tex]. Solving for r, we get [tex]r = 5.78[/tex] inches. Substituting this into the equation for h, we get [tex]h = -3.85[/tex] inches.

Since we cannot have a negative height, we must discard this value and take the positive value of h, which is approximately 3.85 inches. Therefore, the dimensions of the can of greatest volume that can be made with 150 square inches of tin are a radius of approximately 5.78 inches and a height of approximately 3.85 inches.

Step-by-step explanation:

The selling price of the 501 carat diamond rings is approximately $168,750.00, rounded to the nearest cent.

To find the selling price of the 501-carat diamond rings, we need to use the information given about the cost of the purchase and the markup percentage.

Let's assume the markup percentage is m. Then, the selling price S can be calculated as:

S = C * (1 + m/100)

where C is the cost of the purchase ($125,000 in this case).

If the markup percentage is not given, we can use another piece of information to calculate it. For example, if we know that the company wants to earn a profit of P dollars on the sale, we can set the equation:

S - C = P

and solve for the markup percentage:

m = (P/C) * 100

Assuming a markup percentage of 35%, we can calculate the selling price as:

S = 125,000 * (1 + 35/100)

S ≈ $168,750.00

Therefore, the selling price of the 501 carat diamond rings is approximately $168,750.00, rounded to the nearest cent.

Simply put, probability is the likelihood that something will occur. When we don't know how an occurrence will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of occurrences that follow a probability distribution.
It is predicated on the likelihood that something will occur. The justification for probability serves as the primary foundation for theoretical probability. For instance, the theoretical chance of receiving a head when tossing a coin is 12.

90% don't have of those 99%
5% will be positive
1% positive of those 1%
90% positive
10% negative.
Well we need it to be the same, so 99*(.05*.05+.95*.95)+.01*(.9*.9+.1*.1)= 90.4%.

If product of two numbers is 19,200 and HCF is 40, then the LCM is 480

Given that the product of two numbers is 19,200 and the highest common factor (HCF) is 40.

Let us assume the two numbers to be x and y.

Therefore, x × y = 19,200

Also, HCF of x and y is 40.

We can write x = 40a and y = 40b, where a and b are co-prime.

Then, x × y = 40a × 40b = 1600ab = 19,200

Therefore, ab = 12

Now, we need to find the LCM of x and y.

LCM(x, y) = (x × y)/HCF(x, y) --- (1)

Substituting the values of x, y and HCF in the above equation, we get,

LCM(x, y) = (40a × 40b)/40 = 40ab

= 40 × 12 (as ab = 12)
