What is the sum of 18+516+38 1 8 + 5 16 + 3 8 ?

Answer:

To find the number of bags of rice in 2850kg, we need to divide the total weight of rice by the weight of each bag. In this case, each bag weighs 50kg, so:

Number of bags = 2850 kg / 50 kg per bag

Simplifying this expression, we get:

Number of bags = 57 bags

Therefore, there are 57 bags of rice in 2850kg.

To find the value, we need to know the price per bag of rice. If we know this price, we can simply multiply the number of bags by the price per bag to get the total value. Without knowing the price, we cannot determine the value.

The quadratic equation in the given graph can be written in the vertex-form as:

y = -2(x - 1)² + 4

We can see the graph of a quadratic equation. Remember that a quadratic equation with a vertex (h, k) and a leading coefficient a can be written as:

y = a*(x - h)² + k

in the graph we can see that the vertex is (1, 4), replacing that we will get:

y = a*(x - 1)² + 4

In the graph we also can see that the curve passes through the point (0, 2), replacing thesevalues in the equation we will get:

2 = a*(0 - 1)² + 4

2 = a + 4

-2 = a

Then the quadratic is:

Therefore , the solution of the given problem of interest comes out to be Offer 1 should be selected by the new homeowner since it has a reduced overall cost.

Divide the sum by the funding cost, the remaining time, and other factors to determine the simple interest rate. Principal loan repayment hours is the marketing plan with the simplest return. The simplest way to determine involvement is through this technique. In most instances, income is calculated as a percentage of the starting sum.

Here,

Part A: To start, we must divide the yearly interest rate by 12 to determine the monthly interest rate:

Monthly interest rate equals 24.90% divided by 12 equals 0.0249 per month.

=> Monthly payment = (P * r) / (1 - (1 + r)⁻ⁿ

=> Monthly payment = $104.23 per month

=>  (2784 * 0.0249 / (1 - (1 + 0.0249)(-36)).

Taking the entire number of months (36) into account, we get:

Cost of the whole deal 1 = 36 * $104.23 = $3,751.28

As a result, offer 1's overall price is $3,751.28.

Part B:

First, we figure out the interest rate per month:

Monthly interest rate = 22.90% / 12 = 0.0229 / month.

=> Monthly payment = (P * r) / (1 - (1 + r)⁻ⁿ

=> Monthly payout

=> (1 - (1 + 0.0229)(-48)) / (2784 * 0.0229) ≈ $82.12/month

Using the entire number of months (48) as a multiplier, we obtain:

Cost of the whole deal 2 = 48 * $82.12 = $3,938.56

Part C:

Offer 1 costs $3,751.28 in total, while Offer 2 costs $3,938.56 in total.

Offer 1 should be selected by the new homeowner since it has a reduced overall cost.

Answer: a) We know that the Revenue equation is a polynomial of order 1, so we can write it in the form:

R(x) = ax + b

where a and b are constants to be determined. We also know that R(1) = 1 and R(5) = 9, so we have two equations:

a(1) + b = 1

a(5) + b = 9

Solving these equations simultaneously, we get:

a = 2, b = -1

Therefore, the Revenue equation is:

R(x) = 2x - 1

Similarly, the Cost equation is a polynomial of order 2, so we can write it in the form:

C(x) = ax^2 + bx + c

where a, b, and c are constants to be determined. We know that C(1) = R(1) = 1 and C(5) = R(5) = 9, so we have two equations:

a(1)^2 + b(1) + c = 1

a(5)^2 + b(5) + c = 9

We also know that C(2) = 0, so we have a third equation:

a(2)^2 + b(2) + c = 0

Solving these equations simultaneously, we get:

a = 1, b = -4, c = 4

Therefore, the Cost equation is:

C(x) = x^2 - 4x + 4

b) The common solutions to the Revenue and Cost equations represent the production level(s) at which the company makes a profit, since the Revenue equation represents the amount of money the company earns and the Cost equation represents the amount of money the company spends. In other words, the common solutions are the values of x for which R(x) - C(x) > 0. At these production levels, the company's revenue is greater than its cost, resulting in a profit. At production levels where R(x) - C(x) < 0, the company is making a loss. At production levels where R(x) - C(x) = 0, the company is breaking even. Therefore, the common solutions to the two equations signify the production levels at which the company makes a profit or breaks even.

Answer:

We can use the formula for average rate of change to find the rate at which the gas is being used:

average rate of change = (change in y) / (change in x)

where y is the number of gallons left in the tank and x is the number of hours driven.

Substituting the given values, we get:

average rate of change = (5 - 14) / (5 - 0)

Simplifying, we get:

average rate of change = -9/5

Therefore, the rate at which the gas is being used is -9/5 gallons per hour, or -1.8 gallons per hour. This means that the gas in the tank is decreasing at a rate of 1.8 gallons per hour.

The calculated value mean of the sampling distribution for this population is 56

The mean of the sampling distribution for a population with a normal distribution is equal to the population mean.

Therefore, in this case, the mean of the sampling distribution is also 56.

To understand why this is the case, we can consider the central limit theorem, which states that the sampling distribution of the mean of a random sample from a population with any distribution will be approximately normal if the sample size is large enough.

This means that as the sample size increases, the mean of the sampling distribution approaches the population mean.

The correct graph would be the one with a normal distribution curve centered at 0, with two tails shaded on either side, representing the lowest and highest 4% of scores So option C is correct.

What is standard normal distribution ?

The standard normal distribution is a special case of the normal distribution in which the mean is 0 and the standard deviation is 1. It is also known as the "Z-distribution" because the scores are expressed in terms of their z-scores, which are the number of standard deviations above or below the mean.

The standard normal distribution is a bell-shaped curve that is symmetric around the mean of 0. It is used in statistics as a reference distribution for calculating probabilities and making statistical inferences.

To convert a normal distribution with a given mean and standard deviation to a standard normal distribution, we use the formula:

z = (x - μ) / σ

According to the question:
To find the bone density test scores that can be used as cutoff values separating the lowest 4% and highest 4%, we need to find the z-scores that correspond to the 4th and 96th percentiles of the standard normal distribution.

Using a standard normal table, we find that the z-score corresponding to the 4th percentile is approximately -1.75, and the z-score corresponding to the 96th percentile is approximately 1.75.

Therefore, the bone density test scores that can be used as cutoff values separating the lowest 4% and highest 4% are approximately -1.75 and 1.75, respectively.

To sketch the region containing the lowest 4% and highest 4%, we need to shade the area under the normal curve to the left of -1.75 and to the right of 1.75.

The shaded regions represent the lowest 4% and highest 4% of bone density test scores, respectively. The correct graph would be the one with a normal distribution curve centered at 0, with two tails shaded on either side, representing the lowest and highest 4% of scores.

Each element of X is given precisely one element of Y by the function from a set X to a set Y. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively. Initially, functions represented the idealized relationship between two variable quantities.

The function F(x) = x^2 represents a quadratic function, where the input value (x) is squared to produce the output value (F(x)).

To find the value of F(2), we simply need to substitute 2 in place of x in the equation:

F(2) = (2)^2 = 4

This means that when we input the value 2 into the function, it will output the value 4.

Answer:

Step-by-step explanation:

The polynomial function f(x) which produced the graph shown is f(x) = -6(x - 1/2)²(x + 1)²(x - 2).

In Mathematics and Geometry, a polynomial graph touches the x-axis at zeros, roots, solutions, x-intercepts, and factors with even multiplicities.

By critically observing the graph of the polynomial function shown above, we can logically deduce that its x-intercepts include the following;

x = -1 ⇒ x + 1 = 0.

x = 2 ⇒ x - 2 = 0.

Also, the graph has a zero of multiplicity 2 at x = 1/2;

x = 1/2 ⇒ x - 1/2 = 0.

(x - 1/2)²

In this context, an equation that represent the polynomial function is given by:

f(x) = a(x - 1/2)²(x + 1)²(x - 2)

By evaluating and solving for the leading coefficient "a" in this polynomial function based on the y-intercept (0, 3), we have;

3 = a(0 - 1/2)²(0 + 1)²(0 - 2)

3 = a(1/4)(-2)

3 = -a/2

a = -6.

Therefore, the required polynomial function is given by:

f(x) = -6(x - 1/2)²(x + 1)²(x - 2)

Area of rectangle = length x width = 84 ft x 36 ft = 3,024 square feet

A_semicircle = (1/2)πr^2 = (1/2) x 3.14 x 18^2 = 508.68 square feet

The total area of the two semicircles is:

2 x A_semicircle = 2 x 508.68 = 1017.36 square feet

The area of the rectangle plus the area of the two semicircles is:

A_track_outer = A_rectangle + 2 x A_semicircle
