Answer:3,575 lbs, or 45% less

Step-by-step explanation:

Unit for garbage collected: pounds (lbs)

Unit for time: month (mo)

Let's use "t" as the variable for time (in months).

Expression for the amount of garbage collected:

For the initial cleanup: 6,500 lbs

For subsequent cleanups: 45% less garbage collected each month, which means they collect 55% of the previous month's garbage. So, the expression for the amount of garbage collected each month (starting from the second month) would be:

0.55^(t-1) * 6,500 lbs

where "t" represents the number of months after the initial cleanup.

Note that for t=1 (i.e., the first subsequent cleanup), the expression evaluates to 0.55^(1-1) * 6,500 lbs = 6,500 * 1 = 6,500 lbs, which is consistent with the initial cleanup. For t=2, the expression evaluates to 0.55^(2-1) * 6,500 lbs ≈ 3,575 lbs, which is 45% less than the amount collected in the first subsequent cleanup.

Andrés is 35 years old, Carlos is 31 years old, and Rodolfo is 24 years old based on the sum is given.

Let's assume the age of Andrés is x years.

According to the problem, Carlos' age is (x - 4) years and Rodolfo's age is (x - 11) years.

Now, we know that the sum of their ages is 90, so we write an equation:

x + (x - 4) + (x - 11) = 90

Simplify following equation:

3x - 15 = 90

Adding 15 to both sides, we get:

3x = 105

Dividing by 3, we get:

x = 35

So Andrés' age is 35 years.

Carlos' age is (x - 4) = 31 years.

Rodolfo's age is (x - 11) = 24 years.

Toby sold 16 more games than Molly.

A ratio is a comparison of two or more quantities of the same kind. It is often expressed as a fraction or with a colon (:). For example, the ratio of the number of boys to the number of girls in a class of 30 students could be 2:3, which means that for every two boys, there are three girls.

Let's start by finding the total number of parts in the ratio: 5 + 3 + 1 = 9.

Next, we can use the ratio to find out how many parts of the total each person sold:

Katie: 5/9 of 72 games = 40 games

Toby: 3/9 of 72 games = 24 games

Molly: 1/9 of 72 games = 8 games

To find out how many more games Toby sold than Molly, we can subtract Molly's sales from Toby's sales: 24 - 8 = 16.

Therefore, Toby sold 16 more games than Molly.

The proportion of students who took ACT and scored between 18 and 28, P(18 < X < 28) is 0.607.

The proportion of students who took ACT and scored between 18 and 28, P(18 < X < 28) is given by the formula:

P(18 < X < 28) = P(Z < (28 - 21)/5.5) - P(Z < (18 - 21)/5.5)

We can then calculate the z-scores for the lower and upper bounds of the range as follows:

Z1 = (28 - 21)/5.5 = 1.27Z2 = (18 - 21)/5.5 = -0.55

Using a z-table or calculator, we can find the probabilities associated with these z-scores:

P(Z < 1.27) = 0.898P(Z < -0.55) = 0.291

Therefore,P(18 < X < 28) = P(Z < 1.27) - P(Z < -0.55) = 0.898 - 0.291 = 0.607

The experimental probability of the following spin landing on white is 5/7, or roughly 0.714 based on given events.

The number of times an event occurred divided by the total number of trials done is used to compute the experimental probability of the event. In this instance, there have been 14 trials, and the event is landing on white.

Out of 14 spins, the spinner landed on white 10 times, according to the information provided. the following is the experimental likelihood of landing on white:

Experimental probability is calculated as follows: White landings / total spins

10/14 is the experimental probability.

5/7 is the experimental probability.

Hence, the experimental likelihood that the following spin will land on white is 5/7, or roughly 0.714. It's crucial to keep in mind that this likelihood is just based on the small sample size of 14 spins and might not fully reflect the spinner's long-term chances of landing on white.

The design and balance of the spinner might affect the results, thus if there are any problems with its construction, the spinner may not be an accurate depiction of likelihood. The experimental probability might not be helpful in this situation to forecast future events.

You want the determinant of the matrix ...

  [tex]\left[\begin{array}{cc}1&-2\\3&4\end{array}\right][/tex]

The determinant of a matrix is a sum of products. Each product is the element of a row or column multiplied by its cofactor.

For a 2×2 matrix, this becomes the difference between the product of diagonal terms and the product of off-diagonal terms:

  (1·4) - (3·(-2))

  = 4 +6

  = 10

__

Additional comment

The cofactor of term a[i, j] is (-1)^(i+j)·det(M[i,j]), where M[i,j] is the minor matrix obtained by removing row i and column j from the original. As you can see, this definition of a determinant is recursive.

The above describes the determinant of a 2×2 matrix. The determinant of a 3×3 matrix resolves to a sum of 6 3-element products. For larger matrices, the computation burden can be reduced by taking advantage of rows or columns containing zeros.

To find the percent decrease in customers, we first need to find the difference in the number of customers between the two given hours.

Number of customers on Saturday from 6:00 p.m. to 7:00 p.m. = 68

Number of customers on Wednesday from 5:00 p.m. to 6:00 p.m. = 5

Difference in number of customers = 68 - 5 = 63

Next, we need to find the percent decrease in customers, which is given by:

(percent decrease) = (difference / original) x 100%

where "original" refers to the number of customers on Saturday from 6:00 p.m. to 7:00 p.m.

Plugging in the values, we get:

(percent decrease) = (63 / 68) x 100% ≈ 92.65%

Therefore, the percent decrease in customers from the given hour on Saturday to the given hour on Wednesday is approximately 92.65%.

The proportion of adults who have little faith in their automobiles, or the chance of success (p), is 44%.

The probability of an event occurring is referred to as probability. We frequently have to make predictions about the future in real life. We may or may not be aware of the outcome of an event.

At the point when this happens, we broadcast that there is plausible that the occasion will happen.

In conclusion, probability can be put to great use in business as well as in this rapidly expanding field of artificial intelligence. By simply dividing the total number of outcomes by the favorable number of possibilities, the probability of an event can be calculated using the probability formula.

Given that "p" stands for probability—that is, the fact that 45 percent of adults in the United States have little faith in their automobiles—p = 0.45, the likelihood of failure is q = 1-p = 1 - 0.45.

The chance of success (p), or the percentage of adults who have little faith in their automobiles, is therefore 44%, with q =0.55.

The value of B using Sine law is approximately 41.7 degrees.

To use the sine law to find angle B, we need to have either the length of side b or the sine of angle B. However, we can use the sine law to set up an equation involving sine B and then solve for it.

the sine law states:

a/sin A = b/sin B = c/sin C

where a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the opposite angles.

In this case, we are given a = 28.82 ft, c = 47.74 ft, and we want to find B. We can set up the following equation using the sine law:

a/sin A = c/sin C

Substituting the given values:

28.82/sin A = 47.74/sin C

Now, we need to find sin A and sin C. Since the angles in a triangle add up to 180 degrees, we have:

A + B + C = 180

We know that A and C are the angles opposite to sides a and c, respectively, so we can use the sine ratio to express them in terms of a and c:

sin A = a/cos B

sin C = c/cos B

Substituting these expressions into the equation above, we get:

28.82/(a/cos B) = 47.74/(c/cos B)

Simplifying and solving for cos B, we get:

cos B = (28.82 * c) / (a * 47.74)

Now that we know cos B, we can use the identity sin^2 B + cos^2 B = 1 to find sin B:

sin B = sqrt(1 - cos^2 B)

Substituting the given values, we get:

sin B = sqrt(1 - ((28.82 * 47.74) / (a * c))^2)

Calculating this expression gives:

sin B = 0.667

Therefore, angle B is:

B = sin^-1(0.667) = 41.7 degrees (rounded to one decimal place)

So, angle B is approximately 41.7 degrees.

The value of the investment after 3.5 years is approximately $2530.67.

The principal amount refers to the initial amount of money borrowed or invested, excluding any interest or additional fees. For example, if someone takes out a loan for $10,000, the principal amount is $10,000, and this is the amount that must be repaid to the lender, not including any interest that may accrue over time. Similarly, if someone invests $5,000 in a savings account, the principal amount is $5,000, and any interest earned on that amount will be calculated based on the principal amount. The principal amount is an important concept in finance and investing, as it determines the starting point for calculating interest, returns, and other financial transactions.

The formula for compound interest is:

[tex]A= P(1+\frac{r}{n} )^{nt}[/tex]

Where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

In this case, we have:

P = 2000

r = 0.04 (4% as a decimal)

n = 12 (compounded monthly, so 12 times per year)

t = 3.5 (3.5 years)

Plugging these values into the formula, we get:

[tex]A= 2000(\frac{1+0.04}{12})^{12*3.5}[/tex]

A = 2000(1.00333333)⁴²

A ≈ 2530.67

Therefore, the value of the investment after 3.5 years is approximately $2530.67.

The answer is  option (d)  "The volume of  sphere can be interpreted as  product of  radius cubed and  constant factor."

The volume of a three-dimensional object refers to the amount of space that it occupies. More specifically, it is a measure of the amount of enclosed space within a solid shape, like a cube, sphere, cylinder, or any other three-dimensional object. The formula for calculating volume of  solid depends on its shape. The formula for the volume of a sphere, as mentioned in the previous question, is V=4/3πr³, where r is the radius of the sphere.

Volumes are typically measured in cubic units, like cubic meters, cubic centimeters, or cubic feet.

The statement that is true is: "The volume of sphere can be interpreted as  product of radius cubed and  constant factor."

The formula for the volume of a sphere, V=4/3πr³, shows that the volume is proportional to the cube of the radius. This means that if the radius of a sphere is doubled, the volume will increase by a factor of 2³=8. Similarly, if the radius is tripled, the volume will increase by a factor of 3³=27.

The constant factor in the formula, 4/3π, is a fixed value that applies to all spheres, regardless of their size. It is a constant because it does not depend on the radius of the sphere.

Therefore, we can interpret the formula for the volume of a sphere as the product of the radius cubed and a constant factor.

The probability of spending more than 4 days in recovery is 0.8554

To calculate the probability of spending more than 4 days in recovery, we need to use the standard normal distribution since the patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.6 days and a standard deviation of 1.5 days.

The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.

If X is a normally distributed random variable with mean μ and standard deviation σ, then Z = (X-μ) / σ is a standard normal random variable.

So, P(X > 4) = P(Z > (4-5.6) / 1.5) = P(Z > -1.0667)

Using a standard normal distribution table, we find that P(Z > -1.0667) = 0.8554
