Step-by-step explanation:

x is the number of miles driven, and I'm assuming that's supposed to say that he plans on driving 500 miles per day and has $210 to spend. We need a cost equation for his trip. $68.64 is the flat fee the company charges regardless of how many miles, x, are driven. If they charge $.12 per mile, that's the rate per mile of the equation which is the same thing as the slope of the linear equation. The cost equation is

y = .12x + 68.64

If he has $210 to spend, let's see how many miles he can go on that by subbing in 210 for y:

210 = .12x + 68.64 and

141.36 = .12x so

x = 1178

He can drive a total of 1178 miles with $210. If he drives 500 miles per day, 1178/500 = 2.356 days. So depending upon when he has to return the car and assuming it's in the morning, he can keep the car for 2 full days and stay within his budget.

The magnitude of the acceleration of the speck of clay on the edge of the potter's wheel is approximately 4.85 meters per second squared.

To find the magnitude of the acceleration of a speck of clay on the edge of a potter's wheel, we need to determine the angular velocity of the wheel first.

The angular velocity (ω) can be calculated using the formula:

ω = 2πf

Where f is the frequency of rotation in revolutions per second. In this case, the frequency is 51 rpm, which can be converted to revolutions per second by dividing by 60:

f = 51 rpm / 60 = 0.85 revolutions per second

Now we can calculate the angular velocity:

ω = 2π * 0.85 = 5.36 radians per second

The linear velocity (v) of the speck of clay on the edge of the wheel can be calculated using the formula:

v = ωr

Where r is the radius of the wheel. Since the diameter is given as 34 cm, the radius is half of that:

r = 34 cm / 2 = 17 cm = 0.17 meters

Now we can calculate the linear velocity:

v = 5.36 radians per second * 0.17 meters = 0.91 meters per second

Finally, the magnitude of the acceleration (a) can be calculated using the formula:

a = v^2 / r

Plugging in the values:

a = (0.91 meters per second)^2 / 0.17 meters = 4.85 meters per second squared

What is Binomial Distribution ?

The binomial distribution is the discrete probability distribution used in probability theory and statistics that only allows for Success or Failure as the possible outcomes of an experiment. For instance, if we flip a coin, there are only two conceivable results: heads or tails, and if we take a test, there are only two possible outcomes: pass or fail. A binomial probability distribution is another name for this distribution.

This is a binomial distribution, the probability distribution function is

P(X =x) = C^320 (0.15)^3(1-0.15)^20-3

           = [(20x19x18)/2x3](0.15)^3(1-0.15)^20-3

           = 0.2428

As a result, 0.2428 is the likelihood that the sample contains exactly three graduate students.

The test statistic-z or z-score will be 1.635.

What is test statistic-z?

A z-score, also known as a z-statistic, is a number that represents how many standard deviations above or below the mean population a z-test score is. It is essentially a numerical measurement that describes the relationship of a value to the mean of a collection of values. A z-score of 0 implies that the data point's score is the same as the mean score. A z-score of 1.0 indicates that the result is one standard deviation from the mean. Z-scores can be positive or negative, with a positive number indicating that the score is higher than the mean and a negative value indicating that it is lower than the mean.

Let p indicate the proportion of customers who are satisfied.

35 and 90 are the minimum and maximum values of the data set.

It means all observations are between those two numbers.

Hence the answer is 100%

Approximately 100% of the observations are between 35 and 90 in the given data set.

What is a median?

In statistics, the median is a measure of central tendency that represents the middle value of a set of data when arranged in ascending or descending order. It divides the data into two equal halves, with 50% of the values falling below the median and 50% falling above it.

To find the median, the data set is first arranged in order from smallest to largest (or vice versa). If the data set has an odd number of observations, the median is the middle value. For example, in a set of {1, 3, 5, 7, 9}, the median is 5.

The five-number summary consists of the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value. In this case, the minimum value is 35, and the maximum value is 90. Since these values define the range of the data set, all the observations are between these two values.

Therefore, approximately 100% of the observations are between 35 and 90.

When long radishes (SLSL) are crossed to oval radishes (SLSR), the F1 generation will all have the genotype SLSR because they inherit one allele for long shape from one parent and one allele for oval shape from the other parent. When the F1 generation is allowed to cross at random among themselves, the expected phenotypic ratio in the F2 generation will be 1:2:1 for long:round: oval.

This is because each F1 individual can produce gametes with either the S allele or the L allele, and the S allele is dominant over the L allele for determining shape.

So, when two F1 individuals with the SLSR genotype cross, there are four possible offspring genotypes: SSLR (long), SLSR (long), SRSR (round), and SLSL (oval). The probability of each genotype is 1/4. However, since the S allele is dominant over the L allele, both the SSLR and SLSR genotypes will express the long-shape phenotype. Thus, the phenotypic ratio in the F2 generation will be 1 long: 2 round: 1 oval.

In summary, when long radishes are crossed to oval radishes and the F1 generation is allowed to cross at random among themselves, the expected phenotypic ratio in the F2 generation will be 1 long : 2 round : 1 oval.

The value of x must be between -18 and -6. The solution has been obtained using Triangle inequality theorem.

What is Triangle inequality theorem?

The triangle inequality theorem explains how a triangle's three sides interact with one another. This theorem states that the sum of the lengths of any triangle's two sides is always greater than the length of the triangle's third side. In other words, the shortest distance between any two different points is always a straight line, according to this theorem.

We are given three sides of a triangle as 8, 6 and x+20

Using Triangle inequality theorem,

⇒8+6 > x+20

⇒14 > x+20

⇒-6 > x

Also,

⇒x+20+6 > 8

⇒x+26 > 8

⇒x > -18

Also,

⇒x+20+8 > 6

⇒x+28 > 6

⇒x > -22

From the above explanation it can be concluded that x is less than -6 but greater than -22 and -18.

This means that x must lie between -18 and -6.

Hence, the value of x must be between -18 and -6.

Gareth has a capital gain of $34,894, which he will need to include in his assessable income.

To determine the amount Gareth has to include in his assessable income, we need to calculate the capital gain or loss on the sale of the rental house. Here's a breakdown of the calculations based on the given information:

Cost Base:

The cost base is the initial purchase price of the house plus any additional costs incurred to acquire or improve the property. In this case:

Cost Base = Purchase Price + Stamp Duty + Initial Repairs + Rates and Taxes + Interest on Loan

Cost Base = $175,000 + $8,425 + $3,100 + $15,300 + $56,000

Cost Base = $257,825

Adjusted Cost Base:

The adjusted cost base takes into account the depreciation deductions claimed (Division 43 deductions in this case).

Adjusted Cost Base = Cost Base - Division 43 Deductions

Adjusted Cost Base = $257,825 - $42,719

Adjusted Cost Base = $215,106

Capital Gain or Loss:

Capital Gain or Loss = Sale Price - Adjusted Cost Base

Capital Gain or Loss = $250,000 - $215,106

Capital Gain or Loss = $34,894

Gareth's assessable income from the sale of the rental house is $34,894. This is calculated by subtracting the adjusted cost base from the sale price, resulting in the capital gain.

The sum of (5.84×10^2) and (2.85×10^2) in scientific notation is 8.69×10^2.

To add numbers in scientific notation, we need to ensure that the exponents (powers of 10) are the same. In this case, both numbers have an exponent of 2.

(5.84×10^2) + (2.85×10^2)

Since the exponents are the same, we can add the coefficients:

5.84 + 2.85 = 8.69

Now, we keep the same exponent (2) and write the sum in scientific notation:

8.69×10^2

When we add (5.84×10^2) and (2.85×10^2), we get a sum of 8.69×10^2. This means the sum is 869 in standard form. Adding numbers in scientific notation involves adding the coefficients and keeping the exponent the same. In this case, the exponents were already the same, so we simply added the coefficients to obtain the final result.

To estimate the number of observations that are more than 74, we can use the properties of the normal distribution.

Given that the data are drawn from a bell-shaped distribution with a mean of 50 and a standard deviation of 12, we can calculate the z-score for the value of 74.

The z-score is a measure of how many standard deviations a value is away from the mean in a normal distribution. It is calculated using the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

In this case, we can calculate the z-score for x = 74 as:

z = (74 - 50) / 12 = 2

Once we have the z-score, we can use a standard normal distribution table or calculator to find the proportion of observations that are above this z-score. The z-score of 2 corresponds to approximately 0.9772 on the standard normal distribution table.

To estimate the number of observations more than 74, we multiply this proportion by the total number of observations (250):

Number of observations more than 74 = Proportion above 74 * Total number of observations

= 0.9772 * 250

≈ 244

Therefore, approximately 244 observations out of the 250 are expected to be more than 74.
