160 ounces or 10 pounds of cheese is $ 15 and 84 cents.

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Direct Variation

When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other. For instance, a rise in the quantity of commodities will result in higher costs.

Indirect Variation

A change in one quantity will directly affect a change in another, known as a direct variation. A rise in the quantity of goods, for instance, will result in higher costs.

We can say 1 pound = 16 ounces

10 pounds = 10 * 16 = 160 ounces

10 ounces of cheese is 99 cents

1 ounce of chess is 99/10 cents

160 ounces of cheese is 99*160/10 = 1584 cents = $ 15 and 84 cents.

Step-by-step explanation:

Probability of getting minimum value of 20 fair dice rolls to be 1 is (1/6)^20 = 1.275 * 10^-9.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

Let X be a random variable representing the minimum value among 20 fair six-sided dice rolls. We are interested in finding P(X = 1).

The event {X = 1} occurs if and only if all 20 dice rolls result in a 1. The probability of a single dice rolling a 1 is 1/6, and the rolls are independent, so the probability of all 20 dice rolling a 1 is (1/6)^20. Hence,

P(X = 1) = (1/6)^20 = 1.275 * 10^-9.

Probability of getting minimum value of 20 fair dice rolls to be 1 is (1/6)^20 = 1.275 * 10^-9.

The equation which represents total pay P and number of copies sold N is P =1800 + 70N and the total pay for 28 copies sells will be $3760.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

From the question, we were given the following parameters

P = total pay

The length of BD is approximately 8.62 cm and the length of CD is approximately 4.30 cm.

A: Length of BD:

Using the law of sines, BD can be calculated as:

BD = 10 * sin(56) = 8.62 cm (approx)

B: Length of CD:

Using the Pythagorean theorem, AD can be calculated as:

AD = sqrt(BD^2 + AB^2 - 2 * BD * AB * cos(56)) = 12.92 cm (approx)

And then, CD can be calculated as:

CD = AD - BD = 12.92 cm - 8.62 cm = 4.30 cm (approx)

The pressure gradient is a function of the pressure itself, the local acceleration due to gravity, and the density of the fluid.

The sum-of-forces equation is 0=∑ify,i=pa−(p dp)a−ρagdy. Rearranging the equation to isolate dp yields the following expression:

dp = (pa - ρagdy) / p

Differentiating both sides with respect to y yields the differential equation for pressure:

dp/dy = (a(pa - ρagdy) - (dp)(pa)) / p

This equation can be further simplified using the product rule to yield:

dp/dy = pa2/p2 - ρag/p.

For an nth root, there are n solutions of the equation z^n = ω.

To find these solutions, we use the polar form of z = r * e^(iθ). Substituting into the equation, we get:

r^n * e^(iθn) = s * e^iφ

Comparing the magnitude of both sides, we have:

r^n = s

Comparing the phase of both sides, we have:

nθ = φ + 2πk (where k is an integer)

So, we can set:

r = s^(1/n)

θ = (φ + 2πk) / n

Therefore, the n solutions are:

z = s^(1/n) * e^(i(φ + 2πk) / n)

for k = 0, 1, 2, ..., n-1.

20 feet per minute is equal to 400 yards/hour

What is unit rate?

A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

For 1 minute 20 feet

For 60 minutes , 60*20=1200 feet

1 hour = 60 minutes

Thus, we have 1200 feet per hour

3 feet = 1 yard

So, 1200 feet = 1200/3 yrads = 400 yards

Thus, 20 feet per minute is equal to 400 yards/hour

The answer to this question requires the use of the Poisson distribution and the cumulative distribution function.

(a) We are asked to find the probability that the fourth person weighed is the first person to be overweight. Since 63% of Americans are overweight, this means that the probability of a randomly selected American being overweight is 0.63. The probability of the first overweight person being the fourth person weighed is given by P(X=3) where X is the number of overweight people in the first 4 people weighed. Using the binomial distribution formula, we have:

[tex]P(X=3) = (4 choose 3) * (0.63)^3 * (0.37)^1\\\\ = 4 * (0.63)^3 * (0.37)[/tex]

(b) We are asked to find the probability that it takes more than 4 people to observe the first overweight person. This is equivalent to finding the probability that none of the first 4 people weighed are overweight. Using the complement rule, we have:

[tex]P(X=0) = 1 - P(X > 0)\\\\ = 1 - [P(X=1) + P(X=2) + P(X=3) + P(X=4)]\\\\ = 1 - [ (4 choose 1) * (0.63)^1 * (0.37)^3 + (4 choose 2) * (0.63)^2 * (0.37)^2 + P(X=3) ][/tex]

(c)  The expected value (mean) of a binomial distribution is given by μ = np, where n is the number of trials and p is the probability of success in each trial. In this case, n=4 and p=0.63. Thus, the mean number of overweight people in 4 trials is 4 * 0.63 = 2.52. The variance of a binomial distribution is given by σ^2 = np(1-p), so in this case the variance is 4 * 0.63 * 0.37 = 1.41. The standard deviation is the square root of the variance, so the standard deviation is approximately [tex]\sqrt{(1.41) } = 1.19[/tex].

The average rate of change and the instantaneous rate of change are same for ƒ(x) = 2x + 5. The solution has been obtained by using the concept of rate of change.

What is rate of change?

The pace at which one quantity changes in relation to another is described by the rate of change function. Simply expressed, the amount of change in one item is divided by the same amount of change in another to determine the rate of change. The relationship between how one quantity changes in relation to a change in another quantity is provided by the rate of change formula.

The average rate of change is:

[tex]r_{avg} =\frac{f(b)-f(a)}{b-a}[/tex], on interval [a,b]

Here, we are given  ƒ(x) = 2x + 5

So,

[tex]r_{avg} =\frac{(2b+5)-(2a+5)}{b-a}[/tex]

[tex]r_{avg} =\frac{2b-2a}{b-a}[/tex]

[tex]r_{avg} =2[/tex]

The slope of f assessed at a single point, such as f′(c), where c is a predetermined point, is the definition of the instantaneous rate of change.

So, for ƒ(x) = 2x + 5,

f′(c) = 2

Therefore, instantaneous rate of change is 2.

(a) The probability that an assembly will have exactly one defect is 0.2.

This can be calculated using the Poisson distribution formula, which states that the probability of a given number of events (in this case, defects) occurring in a given interval is equal to the mean number of events (in this case, defects) multiplied by the exponential of the mean number of events (in this case, defects).

And multiplied by the exponential of the mean number of events (in this case, defects) multiplied by the exponential of the mean number of events (in this case, defects) divided by the factorial of the given number of events (in this case, defects). Thus, the probability of an assembly having exactly one defect is 0.2.

(b) The probability of an assembly having one or more defects is 1 - 0.2 = 0.8. This can be calculated using the same formula as in (a).
