a. The function decreases its value over time.

b. A = 350(1 - 0.2)ˣ, where x is the time.

c.  A ≈ 47 to the nearest whole number.

d. x ≥ 26 to the nearest whole number.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

In 1970, an industrial waste site contained an estimated 350 tons of contaminated soil.

Special cleaning crews were contracted to clean up the site.

The crews can remove 20% of the contaminated soil each year.

a. The function decreases its value over time.

b. A = 350(1 - 0.2)ˣ, where x is the time.

c. 1979 to 1970 = 9.

A = 350(1 - 0.2)⁹

A = 350(0.8)⁹

A = 46.97

A ≈ 47 to the nearest whole number.

d.  1 ≤ 350(0.8)ˣ

log(1) ≤ log(350) + xlog(0.8)

0 ≤ 5.86 - (0.22)x

-26.25 ≤ - x

x ≥ 26 to the nearest whole number.

Therefore, all the required values are given above.

The marginal product of labor from the restaurant producing meals is B. 10.

Marginal product is the change in output to the change in input. It can also be written as (Δy/Δx). Marginal product leads to change in the graph of the function. The gradual increase in production happens due to additional labor.

We know the marginal product is a change in output divided by a change in input.

In the given context output is no. of meals produced and input is no. of employees.

∴ The marginal product is,

Answer: D) 2

Step-by-step explanation:

The standard deviation of the difference between the means of the two populations is given by:-

\(S.E.=\sqrt{\dfrac{\sigma^2_1}{n_1}+\dfrac{\sigma^2_2}{n_2}}}\)

where \(n_1\)= sample size of population 1

\(n_2\)= sample size of population 2

\(\sigma^2_1\)= variance of population 1

\(\sigma^2_2\)= variance of population 2

As per given,

\(S.E.=\sqrt{\dfrac{112.5}{45}+\dfrac{54}{36}}}\\\\=\sqrt{4}\\=2\)

The percent increase from $815 to $1043 is approximately 27.98% as $815 one year to $1043.

Percent means "per hundred" and is a way of expressing a fraction or a ratio as a part of 100. It is denoted by the symbol "%". For example, 50% means "50 per hundred" or "50 out of 100" and is equivalent to the fraction 1/2 or the ratio 50:100.

To find the percent increase from $815 to $1043, we can use the following formula:

percent increase = (new value - old value) / old value * 100%

Plugging in the values we get:

percent increase = ($1043 - $815) / $815 * 100%

percent increase = $228 / $815 * 100%

percent increase = 27.98%

Therefore, the percent increase from $815 to $1043 is approximately 27.98%.

The Intel pays $7,760 to Bally Manufacturing on August 14.

The first step in calculating what Intel Corporation pays Bally on August 14 is to determine the net price of the machinery after the trade discount and the return of $100 due to defects.

The trade discount of 40% is calculated as follows:

Discount = List price × Discount rate

Discount = $13,100 × 0.40 = $5,240

So the net price of the machinery after the trade discount is:

Net price = List price - Discount

Net price = $13,100 - $5,240 = $7,860

After Intel returns $100 of machinery, the cost of the machinery is further reduced to:

Net price after return = Net price - Return

Net price after return = $7,860 - $100 = $7,760

Since the payment terms are 3/10 EOM (end of month), Intel receives a discount of 3% if payment is made within 10 days. The 10-day period begins on August 1 and ends on August 10 (the payment due date). Since Intel pays the bill on August 14, payment is late and the 3% discount does not apply.

The answer is D. No, they are not independent, because P(girl) = 0.46 and P(girl | plays a sport) = 0.54.

What is independent event ?

In probability theory, two events A and B are said to be independent if the occurrence of one event does not affect the probability of the occurrence of the other event. That is, the probability of A occurring does not change based on whether B occurs or not, and vice versa.

Mathematically, two events A and B are independent if and only if the probability of their joint occurrence is the product of their individual probabilities:

P(A and B) = P(A) x P(B)

If this equation holds true, then we can say that A and B are independent events. Otherwise, they are dependent events.

According to the question:
The answer is D. No, they are not independent, because P(girl) = 0.46 and P(girl | plays a sport) = 0.54.

Two events A and B are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. In this case, we want to know if being a girl and playing a sport are independent events.

We are given that P(girl) = 0.46, which means that 46% of the students surveyed are girls. We are also given that P(girl | plays a sport) = 0.54, which means that 54% of the students who play a sport are girls.

If being a girl and playing a sport were independent events, then we would expect P(girl | plays a sport) to be equal to P(girl). However, we see that P(girl | plays a sport) = 0.54, which is different from P(girl) = 0.46.

This means that the probability of a student playing a sport is dependent on their gender. Therefore, being a girl and playing a sport are not independent events.

Answer:

A: y = x^3 + 1

Step-by-step explanation:

Answer:

Explained below.

Step-by-step explanation:

The random variable X is defined as the number of missing pulses and follows a Poisson distribution with parameter (μ = 0.50).

The probability mass function of X is as follows:

\(P(X=x)=\frac{e^{-\mu}\ \mu^{x}}{x!};\ x=0,1,2,3...\)

(a)

Compute the probability that a disk has exactly one missing pulse as follows:

\(P(X=1)=\frac{e^{-0.50}\ 0.50^{1}}{1!}=0.3033\)

Thus, the probability that a disk has exactly one missing pulse is 0.3033.

(b)

Compute the probability that a disk has at least two missing pulses as follows:

\(P(X\geq 2)=1-P(X<2)\\\)

                \(=1-[P(X=0)+P(X=1)]\\=1-[\frac{e^{-0.50}\ 0.50^{0}}{0!}+\frac{e^{-0.50}\ 0.50^{1}}{1!}]\\=1-0.6065-0.3033\\=0.0902\)

Thus, the probability that a disk has at least two missing pulses is 0.0902.

(c)

It is provided that the two disks selected are independent of each other.

The probability that a disk has no missing pulses is:

\(P(X=0)=\frac{e^{-0.50}\ 0.50^{0}}{0!}=0.6065\)

Compute the probability that neither of the two disks contains a missing pulse as follows:

\(P(X_{1}=0,\ X_{2}=0)=P(X_{1}=0)\times P(X_{2}=0)\)

                               \(=0.6065\times 0.6065\\=0.367842\\\approx 0.3678\)

Thus, the probability that neither of the two disks contains a missing pulse is 0.3678.

Based on an equation, the salaries of the two employees whose average weekly salary is $5,500 are as follows:

X = $5,25

S = $5,725.

An equation is a mathematical statement that shows that two or more algebraic expressions are equal or equivalent.

While equations use the equal symbol, mathematical or algebraic expressions combine variables with numbers, constants, and values using mathematical operands.

The average weekly salary of two employees = $5,500

The number of employees = 2

Th,e total weekly salaries of the two employees = $11,000 ($5,500 x 2)

Let the salary of Employee One = x

Let the salary of Employee Two = s

x = s - 450

11,000 = s - 450 + s

11,450 = 2s
