The test with the relative highest score is given by: D. She scored relatively better on the ACT because her z-score is higher.​

In order to determine the test that has the relative highest score, we would determine the z-score for the two tests that Mackenzie took.

Mathematically, the z-score of a given sample score can be calculated by using this formula:

Z-score = (x - μ)/σ

Where:

For the ACT test, we have:

Z-score = (23 - 20.3)/6.0

Z-score = 2.7/6.0

Z-score = 0.45.

For the SAT test, we have:

Z-score = (1150 - 1060)/217

Z-score = 90/217

Z-score = 0.42.

Therefore, Mackenzie had the relative highest score in ACT test because it has a higher z-score than the SAT test.

The largest value (39.5% obese) is 2.11 standard deviations above the mean. The smallest value (23.0% obese) is 2.21 standard deviations below the mean. The mean and standard deviation for the percent of the population that is obese for each of the 50 US states are given as:

Mean: 31.43, Standard Deviation: 3.82

To calculate the z-score for the largest value (39.5% obese), we can use the formula: z = (x - μ) / σ

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

For the largest value: z = (39.5 - 31.43) / 3.82

z ≈ 2.11

The largest value has a z-score of approximately 2.11 standard deviations above the mean.

To calculate the z-score for the smallest value (23.0% obese):

z = (23.0 - 31.43) / 3.82

z ≈ -2.21

The smallest value has a z-score of approximately -2.21 standard deviations below the mean.

Therefore, the interpretation in terms of standard deviations is as follows:

- The largest value (39.5% obese) is 2.11 standard deviations above the mean.

- The smallest value (23.0% obese) is 2.21 standard deviations below the mean.

I) f is continuous at x=2

II) f is differentiable at x=2

These both f (function ) are true

The given limit can be recognized as the definition of the derivative of f at x=2. Specifically, it states that the derivative of f at x=2 is equal to 5.

Using this information, we can make the following conclusions:

I) We cannot say for sure whether f is continuous at x=2 based on the given limit alone. While a function being differentiable at a point implies that it is also continuous at that point, the converse is not necessarily true. Therefore, we would need additional information to determine whether f is continuous at x=2.

II) The given limit implies that f is differentiable at x=2, since the limit exists and is finite. Specifically, we can say that the derivative of f at x=2 exists and is equal to 5.

III) The given limit also implies that the derivative of f is continuous at x=2. This is because the limit defines a continuous function at x=2, and it is well-known that if a function is differentiable at a point, then it is also continuous at that point.

Therefore, the correct answers are II and III.

Answer:

9 comedy

12 horror

Step-by-step explanation:

First, there are 360 degrees in a circle.

Comedy = 90 degrees

Action and romance = 90 degrees combined

Horror = 120 degree

Science fiction = 60 degrees

To find sci fi : 90 +90 +120 = 300 - 360 = 60 degrees

36 students took the survey.

1/4 × 36 = 9

Horror is 120 degrees out of 360 degrees or 1/3 of the circle.

1/3 × 36 = 12

Answer: 12 students

Step-by-step explanation:

360* circle, 1 student per 10* so 120* = 12 students.

To double check, 90* = 9 students.

The first four terms of the binomial series are 1-  1/2 x+  3/16 x^2-  1/16 x^3. (Option C)

In mathematics, the binomial series is a generalization of the polynomial that comes from a binomial formula expression like ^n for a nonnegative integer n. For a binomial series, the formula for the expansion of any terms is given by

(1+x)^m=1+mx+  m(m-1)/2! x^2+  m(m-1)(m-2)/3! x^3+⋯.

For the given function (1+ x/4)^(-2)

m = -2

x = x/4

Hence, using the above expansion formula

The first term = 1

The second term = mx = (-2)(x/4) = -x/2

The third term =m(m-1)/2! (x/4)^2=  (-2(-2-1))/(2*1*16) x^2=3/16 x^2

The fourth term = m(m-1)(m-2)/3! (x/4)^3=(-2(-2-1)(-2-2))/(3*2*1*64) x^3=-1/16 x^3

Hence, the first four terms of the binomial series are 1-  1/2 x+  3/16 x^2-  1/16 x^3.

1. The variable in the solution is the population every year

2. The model can be presented as

y= 1175-20x

3. The value of slope is -20 which says that the population decreases by 20 members for every one year increase from 2010

Let y be the population after x years from 2010

So, the model can be presented as

y= 1175-20x

Now for example, in year 2011

x= 2011-2010= 1

The population is y = 1175-20(1) = 1155

The population in year 2012 is

x= 2012-2010= 2

Population is y= 1175-20(2) = 1135

The result obtained is satisfactory and hence ok

The population follows a linear trend with slope of -20 and intercept of 1175.

Answer:

Speed of car most likely

Step-by-step explanation:

The Law of Large Numbers is a fundamental concept in probability theory and statistics stating the number of trials of a random event increases, the average of the outcomes approaches the expected value of the event. It's better to use 500 trials.

In other words, as we repeat an experiment a large number of times, the proportion of times that a certain outcome occurs will converge to its probability of occurrence. This is an important concept in statistical inference, as it helps to ensure that the results of a sample are representative of the population from which it was drawn.

Now, if you were using the relative frequency of an event to estimate the probability of the event, it would be better to use 500 trials rather than 100 trials. The reason is that the larger the number of trials, the more accurate the estimate of the probability is likely to be.

Using a larger sample size reduces the impact of random variation and provides a more precise estimate of the true probability. The Law of Large Numbers tells us that as the sample size increases, the relative frequency of the event should converge to the true probability, so a larger sample size will generally give a more reliable estimate

The function f(x, y) = x³ + y³ + 21x² - 18y² has neither local max nor local min.

Saddle point is (0, 0).

Given the function is,

f(x, y) = x³ + y³ + 21x² - 18y²

Partially differentiating the functions with respect to 'x' and 'y' we get,

fₓ = 3x² + 42x

fᵧ = 3y² - 26y

fₓₓ = 6x + 42

fᵧᵧ = 6y - 26

fₓᵧ = 0

Now,

fₓ = 0 gives

3x² + 42x = 0

x(x + 13) = 0

x= 0, -13

and fᵧ = 0 gives

3y² - 26y = 0

y (3y - 26) = 0

y = 0, 26/3

So, for (0, 0) both fₓ and fᵧ are zero.

So the discriminant is,

D = fₓₓ(0, 0) fᵧᵧ(0, 0) - [fₓᵧ(0, 0)]² = 42 * (-26) - 0 = - 1092.

So, D < 0 so the function neither has max nor min.

Accoding to the calculations , the correct answer is:

A) Depreciation charge 16,000; revaluation surplus £20,000

According to IAS 16 Property, Plant and Equipment, the depreciation charge for an asset should be based on its carrying amount, useful life, and residual value.

In this case, the buildings were purchased for £400,000 (£480,000 - £80,000) and had a useful life of 25 years. Since there is no residual value, the depreciable amount is equal to the initial cost of the buildings (£400,000).

To calculate the annual depreciation charge, we divide the depreciable amount by the useful life:

£400,000 / 25 = £16,000

Therefore, the depreciation charge for the year ended 30 September 2021 is £16,000.

Now, let's calculate the balance on the revaluation surplus as at that date.

The revaluation surplus is the difference between the fair value of the property and its carrying amount. On 1 October 2020, the property was revalued to £500,000, and the carrying amount was £480,000 (£400,000 for buildings + £80,000 for land).

Revaluation surplus = Fair value - Carrying amount

Revaluation surplus = £500,000 - £480,000

Revaluation surplus = £20,000

Therefore, the balance on the revaluation surplus as at 30 September 2021 is £20,000.

The solutions of the equation 20cosθ=-8 in the interval from 0 to 2π are 0.785 and 5.236, rounded to the nearest hundredth.

To solve the equation, we divide both sides by 20 to get cosθ=-0.4. The cosine function has a period of 2π, so all solutions of the equation can be found by adding multiples of 2π to the solution cosθ=-0.4.

The solutions in the interval from 0 to 2π are then cosθ=-0.4+2πk, where k is an integer. When k=0, we get cosθ=-0.4. When k=1, we get cosθ=-0.4+2π=0.785. When k=2, we get cosθ=-0.4+4π=5.236.

The solutions cosθ=-0.4 and cosθ=5.236 are both in the interval from 0 to 2π. When rounded to the nearest hundredth, these solutions are 0.785 and 5.236, respectively.

The experimental probability that she will get a hit in her next at bat is: Experimental probability = 20 / 50 = 0.4

The experimental probability is calculated by dividing the number of successful outcomes (getting a hit) by the total number of outcomes (times at bat).

In this case, the softball player got a hit in 20 of her last 50 times at bat.

To find the experimental probability of getting a hit in her next at-bat, we can use the formula:

Experimental probability = Number of successful outcomes / Total number of outcomes

In this case, the number of successful outcomes is 20 (the number of times she got a hit) and the total number of outcomes is 50 (her total times at bat).

Therefore, the experimental probability that she will get a hit in her next at bat is:

Experimental probability = 20 / 50 = 0.4

So, the experimental probability is 0.4 or 40%.

This means that there is a 40% chance that the softball player will get a hit in her next at-bat, based on the data from her last 50 times at bat.
