Mergesort is a sorting algorithm that recursively divides the array into smaller subarrays, sorts them individually, and then merges them back together to obtain the final sorted array. The steps of mergesort on the array [10, 4, 1, 5] are: Divide - [10, 4], [1, 5]; Sort - [10], [4], [1], [5]; Merge - [4, 10], [1, 5]; Merge - [1, 4, 5, 10].

Mergesort is a sorting algorithm that follows the divide-and-conquer strategy. It works by recursively dividing the input array into smaller subarrays, sorting them individually, and then merging them back together to obtain the final sorted array. The key step in mergesort is the merging process, where two sorted subarrays are combined to create a single sorted array.

Step 1: Divide the array into smaller subarrays

Split the original array [10, 4, 1, 5] into two subarrays: [10, 4] and [1, 5].

Step 2: Recursively sort the subarrays

For the first subarray [10, 4]:

Divide it into [10] and [4].

Since both subarrays have only one element, they are considered sorted.

For the second subarray [1, 5]:

Divide it into [1] and [5].

Since both subarrays have only one element, they are considered sorted.

Step 3: Merge the sorted subarrays

Merge the first subarray [10] and the second subarray [4] into a single sorted subarray [4, 10].

Merge the first subarray [1] and the second subarray [5] into a single sorted subarray [1, 5].

Step 4: Merge the final two subarrays

Merge the subarray [4, 10] and the subarray [1, 5] into a single sorted array [1, 4, 5, 10].

The final sorted array is [1, 4, 5, 10].

Step-by-step explanation:

A) The equation used to find perimeter is

2L+2W=P

B) Since we know the perimeter is 80 cm and the length is 29 cm, we can make the equation look like this

2(29)+2W=80

Now, we can just solve

58+2w=80

2w=22

w=11 cm

Step-by-step explanation:

1) P= 2(L + W) or 2L + 2W

2) Since the perimeter is given as 80 and the length is given as 29.

P = 2(L + W)

80 = 2( 29 + w)

80= 58 + 2w

collect like terms;

80-58=2w

2w= 22

Divide by what the co- efficient of w

w = 11cm

therefore width is equal to 11cm.

The required population density of Florida is approximately 331.2 people per square mile.

Population density is defined as the number of individuals per unit area. In this case, we want to find the population density of Florida, which is the number of people per square mile. To do this, we can divide the total population of Florida by the total area of the state

We have;

Population = 21, 780, 000

Total area = 65, 758 square miles

Then,Population density is

Population density of Florida = Total population / Total area

Population density of Florida = 21,780,000 / 65,758

Population density of Florida ≈ 331.2 people per square mile

Therefore, the population density of Florida is approximately 331.2 people per square mile.

Answer for Khan academy

The proportion of bicycle prices that are lower than the price of the sports bicycle is approximately 94.52%.

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

We can start by standardizing the sports bicycle price using the formula:

z = (x - μ) / σ

where x is the sports bicycle price, μ is the mean, and σ is the standard deviation.

Substituting the values, we get:

z = (380 - 300) / 50 = 1.6

Now, we can use a standard normal distribution table or calculator to find the proportion of values below 1.6.

From the z-table, we find that this proportion is approximately 0.9452.

Therefore, the proportion of bicycle prices that are lower than the price of the sports bicycle is approximately 94.52%.

The approximate volume of the sphere is 6.01 ft³.

A sphere is simply a three-dimensional geometric object that is perfectly symmetrical in all directions.

The volume of a sphere is expressed as:

Volume =  (4/3)πr³

Where r is the radius of the sphere and π is the mathematical constant pi (approximately equal to 3.14).

Given that the surface area of the sphere is 16 square feet.

First, we determine the radius r:

Surface area = 4πr²

Hence

16 = 4πr²

Dividing both sides by 4π, we get:

r² = 16/4πr

r = √( 16/4πr )

r = 1.128 ft

Plugging in the value of r that we just found, we get:

Volume =  (4/3)πr³

Volume =  (4/3) × 3.14 × (1.128 ft)³

Volume =  6.01 ft³

Therefore, teh volume is 6.01 ft³.

To prove that the sum of the interior angle measures of a triangle is 180 degrees, we can use the concept of parallel lines and transversals.

Consider a triangle ABC and draw a line parallel to one of its sides, intersecting the other two sides at points D and E.

Since AB is parallel to DE, we can observe that the alternate interior angles ∠ABC and ∠AED are congruent, as well as the corresponding angles ∠ACB and ∠ADE.

By applying the angle sum property, we know that the sum of the interior angles of a triangle is equal to 180 degrees. We can conclude that ∠ABC + ∠ACB + ∠BAC = ∠AED + ∠ADE + ∠DAE = 180 degrees.

if T1 and T2 are unbiased estimators of μ(0) and independent of each other, the variance of the estimator aT1 + (1-α)T2 can be expressed as \(a^2 Var(T1) + (1-\alpha )^2 Var(T2)\).

Let's calculate the variance of the estimator aT1 + (1-α)T2, where T1 and T2 are unbiased estimators of μ(0) in R, and α is a constant.

First, we know that the variance of a linear combination of random variables can be expressed as follows:

\(Var(aT1 + (1-\alpha )T2) \\= a^2 Var(T1) + (1-\alpha )^2 Var(T2) + 2a(1-\alpha ) Cov(T1, T2)\),

where Var(T1) and Var(T2) represent the variances of T1 and T2, respectively, and Cov(T1, T2) represents their covariance.

Since T1 and T2 are unbiased estimators, we have E(T1) = E(T2) = μ(0). Therefore, Cov(T1, T2) = E(T1T2) - E(T1)E(T2) = μ(0) - μ(0) = 0, as the estimators are independent.

Substituting the values into the variance formula, we get:

Var(aT1 + (1-α)T2) =

\(\\a^2 Var(T1) + (1-\alpha )^2 Var(T2) + 2a(1-\alpha ) Cov(T1, T2)\)

\(= a^2 Var(T1) + (1-\alpha )^2 Var(T2).\)

Therefore, if T1 and T2 are unbiased estimators of μ(0) and independent of each other, the variance of the estimator aT1 + (1-α)T2 can be expressed as \(a^2 Var(T1) + (1-\alpha )^2 Var(T2)\).

The probability that a randomly selected car is violating the speed limit of 50 miles per hour is 0.43.

To find the probability that a randomly selected car is violating the speed limit of 50 miles per hour, we need to find the probability that the speed of the car is greater than 50 miles per hour. Since the speed of cars on the road is normally distributed with an average of 51 miles per hour and a standard deviation of 5.9 miles per hour, we can use the standard normal distribution table to find the probability.

First, we need to convert the speed limit of 50 miles per hour to a z-score. This is done by using the formula:

z = (x - μ) / σ

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

z = (50 - 51) / 5.9

z = -0.169

To find the probability of a car going faster than 50 mph, we need to find the probability that z is greater than -0.168. This probability can be found using a standard normal distribution table. The probability that a car goes over 50 mph is around 0.432945.

So the probability that a randomly selected car is violating the speed limit of 50 miles per hour is 0.43.
