On the NASA space shuttles, a substance called kevlar epoxy is employed. This epoxy's strands underwent testing for 90% breaking strength.

Mean, Range, variance, standard deviation

A) Formula for range is;

Range = Highest term - Lowest term

Range = 7.89 - 0.02

Range = 7.87

B) Sum of all the given 50 epoxy samples is gotten to be;

∑X = 62.12

From online statistics calculator, we have; ∑X² = 164.3516

C) Formula for sample mean here is;

x' = ∑x/n

x' = 62.12/50

x' = 1.24

Formula for variance is;

σ² = [∑x² - [(∑x)²/n]]/(n - 1)

σ² = (164.3516 - (62.12²/50))/(50 - 1)

σ² = 1.78

Formula for the standard deviation is;

σ = √variance = √1.78

σ = 1.334

D) Formula for coefficient of variation is;

48 will be the value to ensure that A′ is asymptotically faster than A.

The recurrence relation T(n)=7T(n/2)+n2 is given by the question, and its answer is the asymptotic complexity master theorem T(n)=(nlog49base4).

Therefore, the recurrence relation T′(n)=T′(n/4)+n2 can be used to express the complexity in general.

As a result, the relationship is as follows: a=, b=4, f(n)=n2.

For a value of the >16, nloga base b=nlog base 4, and the >0, f(n)=O(nlog).

As a result, for n > 16, T′(n) = (n log base 4)

Now since A is getting asymptotically faster than A', A must hold:

Base 4 (nlog) nlog49 base 4 Since the base is equal to e, we can calculate the power as follows: log base 4 log49 base 4. Thus, after solving, we will obtain 49.

Therefore, 48 will be the value to ensure that A′ is asymptotically faster than A.

For the segments to be congruent, x should be 13/2.

This is a case of congruency of segments. We know that two segments are congruent if and only if they have equal lengths.

Now, here the two line segments JK and RS have lengths 2x-9 and 30-4x respectively.

So, to be congruent, JK and RS must be of equal length.

Or in other words, 2x-9 = 30-4x

Blinding refers to the nondisclosure of the treatment an experimental unit is receiving in a controlled experiment.

Blinding is a technique used in experimental design to reduce bias and improve the validity of results. It refers to the practice of not revealing to the experimental units (e.g., participants, animals) or the experimenters which treatment they are receiving in a controlled experiment. Blinding is used to eliminate potential sources of bias that might influence the results of the experiment.

For example, if the participants are aware of the treatment they are receiving, they might behave differently and affect the results. Similarly, experimenters might unconsciously treat participants differently based on their knowledge of the treatment, which could also affect the results.

Blinding is the practice of keeping the therapy that an experimental unit is getting a secret. In a single-blind experiment, the experimental unit (also known as the subject) is kept in the dark regarding the therapy that he or she is getting.

For the population model DP/dt = 0.3(1-P/200)(P/50-1)P describes how the population changes over time based on the value of P.

a) The population is in equilibrium at P = 0 and P = 200,

b) increasing for values of P between 50 and 200, and

c) decreasing for values of P between 0 and 50 and values of P greater than 200.

The population model

=> DP/dt = 0.3(1-P/200)(P/50-1)P

is a mathematical expression that describes the change in population size over time.

In this model, P(t) represents the population at time t and the rate of change of the population, DP/dt, is a function of P.

The population is in equilibrium when the rate of change is zero, meaning the population is neither growing nor declining. To find the equilibrium population, we set DP/dt = 0 and solve for P. In this case, we have:

=> 0.3(1-P/200)(P/50-1)P = 0

Solving for P, we find two solutions: P = 0 and P = 200. These represent the minimum and maximum populations, respectively.

The population is increasing when the rate of change is positive, meaning the population is growing.

If DP/dt > 0, then the population is increasing, and if DP/dt < 0, then the population is decreasing.

In this case, we have:

=> DP/dt = 0.3(1-P/200)(P/50-1)P

To simplify, we can write:

=> DP/dt = 0.3(P/50-1)(P/200-1)P

=> (P/50-1)(P/200-1) > 0.

This occurs when 50 < P < 200.

Therefore, the population is increasing for values of P between 50 and 200.

The population is decreasing when the rate of change is negative, meaning the population is declining.

If DP/dt > 0, then the population is increasing, and if DP/dt < 0, then the population is decreasing.

In this case, we have:

DP/dt = 0.3(1-P/200)(P/50-1)P

To simplify, we can write:

DP/dt = 0.3(P/50-1)(P/200-1)P

Since the sign of P is positive, the sign of DP/dt is negative for all values of P where

=> (P/50-1)(P/200-1) < 0.

Therefore, the population is decreasing for values of P between 0 and 50 and values of P greater than 200.

The formula for the probability that exactly k balls are red when a collection of n < min{m, n - m} balls is taken out at random without replacement is given by:P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n) = (m! / (k! * (m - k)!) * (n - m)! / ((n - k)! * (n - m - n + k)!)) / (n! / (n! * 0!)) = (m! * (n - m)!) / (k! * (m - k)! * (n - k)! * n!).

Given n balls, m of which are red and n - m are blue, if a collection of n < min{m, n - m} balls is taken out at random without replacement, the probability that exactly k balls are red can be calculated using the Hypergeometric Distribution. The formula for the probability that exactly k balls are red is given by: P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n)

where C(n, k) denotes the number of combinations of n things taken k at a time, and is given by: C(n, k) = n! / (k! * (n - k)!).

Therefore, the formula for the probability that exactly k balls are red when a collection of n < min{m, n - m} balls is taken out at random without replacement is given by:

P(k red balls) = (C(m, k) * C(n - m, n - k)) / C(n, n) = (m! / (k! * (m - k)!) * (n - m)! / ((n - k)! * (n - m - n + k)!)) / (n! / (n! * 0!)) = (m! * (n - m)!) / (k! * (m - k)! * (n - k)! * n!).

In this case, the limit is 0, so the series is indeed convergent.

The Root Test is used to determine the convergence or divergence of a series. and it is used the Root Test, we start by finding the nth root of each term in the series.

In this case, the series is

=> [∞] n = 1 4 1 1 n n²,

so we calculate the nth root of each term:

[tex]= > (1/n^{2} )^{1/n}[/tex]

Then, we take the limit of this expression as n approaches infinity, to find the value of the root.

If this limit is less than 1, the series is convergent. If the limit is greater than or equal to 1, the series is divergent.

In this case, the limit of [tex](1/n^{2} )^{1/n}[/tex] as n approaches infinity is 0, which is less than 1. This means that the series is convergent.

To confirm this, we can evaluate the limit of the absolute value of each term as n approaches infinity, using the formula

=> lim n → [∞] n |aⁿ|.
