Answer:

120 yards 1.

Step-by-step explanation:

In the shape, it is a rectangle with a triangle cut out from it. What is the area of the shape:

Area of rectangle = length × width

12 × 15 = 180 yards²

Area of triangle = ½ × base × height

½ × 10 × 12 = 60 yards²

Now subtract the area of triangle from the area of rectangle:

180 - 60 = 120 yards ²

The corresponding probabilities of the random variables x = (0, 1, 2, 3, 4, 5, and 6) are  (0.2401, 0.4116, 0.2646, 0.0756, 0.0081, 0, and 0)

Since we are dealing with a binomial probability distribution. We are going to use the binomial distribution formula for determining the probability of x successes:

P(x = r) = nCr . π^r  . q^n-r

Given: n = 4 and π = 0.30, q = 1 - π = 1 - 0.30 = 0.70 and x = (0, 1, 2, 3, 4, 5, 6)

P(x = 0) = 4C0 × 0.3⁰ × 0.7⁴⁻⁰ = 0.2401

P(x = 1) = 4C1 × 0.3¹ × 0.7⁴⁻¹ = 0.4116

P(x = 2) = 4C2 × 0.3² × 0.7⁴⁻² = 0.2646

P(x = 3) = 4C3 × 0.3³ × 0.7⁴⁻³ = 0.0756

P(x = 4) = 4C4 × 0.3⁴ × 0.7⁴⁻⁴ = 0.0081

P(x = 5) = 0

P(x = 6) = 0

Note: P(x = 5) and P(x = 6) are 0 because their x (5 and 6) is greater than the n (4)

Therefore, the probabilities of the random variables x(0, 1, 2, 3, 4, 5, and 6) are  0.2401, 0.4116, 0.2646, 0.0756, 0.0081, 0, and 0 respectively

5) b. low population growth

We have,

1)

A limit imposed by the government on the quantity of a good or product that can be brought into the country is called a quota.

Tariffs, on the other hand, are taxes imposed on imported goods, while foreign bills of exchange refer to payment methods in international trade, and value-added tax (VAT) is a tax on the value added to goods and services.

2)

The argument that enacting trade restrictions makes foreign products cheaper to U.S. shoppers is not effective because it is contradictory.

Trade restrictions, such as tariffs or quotas, are intended to make foreign products more expensive and protect domestic industries from foreign competition.

3)

If a country is on the gold standard, it means that it sets the value of its currency in relation to a specific amount of gold.

The value of the currency is directly linked to the amount of gold held in reserves by the government and can be exchanged for gold at a fixed rate.

4)

Economists tend to classify a country as less developed if the country's average level of income is less than $3,040 per person.

This is the World Bank's definition of low-income countries, which are typically characterized by high levels of poverty, limited access to education and healthcare, and underdeveloped infrastructure.

5)

Low population growth is not considered a barrier to economic development.

In fact, some economists argue that high population growth can put a strain on resources and hinder economic development.

Barriers to economic development typically include factors such as political corruption, lack of investment capital, and low levels of education and human capital.

Step-by-step explanation:

Given the relation :

P = (318t + 6792) / (1.19t + 107.36)

P = % of household with PC

t = years since 2000

1.) We need to find t, when P = 85%

P = 0.85

0.85 = (318t + 6792) / (1.19t + 107.36)

0.85(1.19t + 107.36) = (318t + 6792)

1.0115t + 91.256 = 318t + 6792

Collect like terms :

1.0115t - 318t = 6792 - 91.256

−316.9885t = 6700.744

t = 6700.744 / - 316.9885

t = - 21.138760

t = - 21 years

2000 - 21 years = 1979

Percentage who had computer in 2014

t = 2014 - 2000 = 14

The compound interest earned on a four year investment at $3500 at 4.5% compounded monthly is $724.46 (calculated by subtracting the initial investment amount of $3500 from the total amount of $4224.46).

Compound interest is the interest that is generated on the interest that has been accrued over a certain period of time.

The compound interest that is earned on a four year investment at $3500 at 4.5% compounded monthly can be calculated using the formula for compound interest, which is given as:

A = P(1 + r/n)^(nt)

Where:

A is the total amount of money after the investment period,P is the principal or initial amount of money invested,r is the annual interest rate,n is the number of times the interest is compounded in a year,

t is the total number of years the investment is held.Substituting the given values in the above formula,

we get:A = 3500(1 + 0.045/12)^(12*4)A

= 3500(1 + 0.00375)^(48)A

= 3500(1.00375)^(48)A

= 3500(1.2067)A

I would sell the 1 MW of electricity contract for 12 PM at the bid price of 95 pounds/MWh, and lock in a loss of 5 pounds/MWh.

The projection for solar power has increased from 4 GW to 4.5 GW, which suggests that there will be more electricity available than anticipated by 12 PM, which would probably result in a decrease in market pricing.

The market is illiquid and volatile, as seen by the bid-offer spread of 10 pounds/MWh, and if I wait, the price may swing even further against me.

Regarding the supply or demand of electricity at 12 PM, I have no additional knowledge or predictions, and I don't want to guess on how the market will behave.

Instead of sticking onto the contract and expecting for a price increase, I would rather close my position and reduce the chance of more losses.

Since I am a risk-averse trader, I don't want to expose myself to the electrical market unnecessarily.

I don't have any other investments or hedging plans in the power market that would influence my choice.

I am free to purchase or sell any quantity or grade of power at 12 PM without any restrictions or commitments.

The average number of hours that adults spend working each day is 8 hours and Ryan is correct because he got the average of 8 right.

We know that,

The sample mean is a statistic that is computed by taking the arithmetic mean of the values of a variable in a sample. If the sample is taken from probability distributions with a shared expected value, the sample mean is an estimator of that value.

The mean is gotten from the formula;

x' = ∑x/n

Number of hours of work per day are; 6, 7, 8, 9 and 10

Thus; sum up all of it

∑x = 6 + 7 + 8 + 9 + 10

A circle is a two-dimensional geometric shape that is defined as a set of all points in a plane that are at a constant distance from a single fixed point called the center. The distance between the center and any point on the circle is called the radius, which is a fixed length for all points on the circle.

A circle is a closed curve and is often represented by the symbol "O". It has several important properties, such as its circumference (the distance around the circle) which is given by the formula C=2πr, where r is the radius, and π (pi) is a mathematical constant approximately equal to 3.14159.

So, the area of the circle covered by the sprinkler is:

A = π *\((40)^{2}\) ≈ 5026.55 square feet

Answer:

a) The random variable is the average life of a refrigerator.

b) 0.1151 = 11.51% probability that someone will keep a refrigerator fewer than 11 years before replacement.

c) 0.0548 = 5.48% probability that someone will keep a refrigerator more than 18 years before replacement

d) 0.6472 = 64.72% probability that someone will replace a refrigerator between 8 and 15 years

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Consumer Reports indicated that the average life of a refrigerator before replacement is 14 years with a standard deviation of 2.5 years

This means that:

The random variable is the average life of a refrigerator.

\(\mu = 14, \sigma = 2.5\)

a. State the random variable.

The random variable is the average life of a refrigerator.

b. What is the probability that someone will keep a refrigerator fewer than 11 years before replacement?

This is the pvalue of Z when X = 11. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{11 - 14}{2.5}\)

\(Z = -1.2\)

\(Z = -1.2\) has a pvalue of 0.1151

0.1151 = 11.51% probability that someone will keep a refrigerator fewer than 11 years before replacement.

c. What is the probability that someone will keep a refrigerator more than 18 years before replacement?

This is 1 subtracted by the pvalue of Z when X = 18. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{18 - 14}{2.5}\)

\(Z = 1.6\)

\(Z = 1.6\) has a pvalue of 0.9452

1 - 0.9452 = 0.0548

0.0548 = 5.48% probability that someone will keep a refrigerator more than 18 years before replacement.

d. What is the probability that someone will replace a refrigerator between 8 and 15 years?

This is the pvalue of Z when X = 15 subtracted by the pvalue of Z when X = 8.

X = 15

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{15 - 14}{2.5}\)

\(Z = 0.4\)

\(Z = 0.4\) has a pvalue of 0.6554

X = 8

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{8 - 14}{2.5}\)

\(Z = -2.4\)

\(Z = -2.4\) has a pvalue of 0.0082

0.6554 - 0.0082 = 0.6472

0.6472 = 64.72% probability that someone will replace a refrigerator between 8 and 15 years

Step-by-step explanation:

tThe sum of all arc measures that make up that circle is 360 degrees.

QS + RQ + RS = 360

QS = 360 - 120 - 140 = 100

An arc angle is the degree measurement of that angle inside the circle, opposite the arc

m∠R = arc QS = 100°

Answer:

∠ R = 50°

Step-by-step explanation:

the inscribed angle R is half the measure of its intercepted arc QS

the sum of the arcs on a circle is 360° , that is

RQ + QS + SR = 360°

120° + QS + 140° = 360°

QS + 260° = 360° ( subtract 260° from both sides )

QS = 100°

Then

∠ R = \(\frac{1}{2}\) × 100° = 50°

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.
