Answer: 14) 1.5, 15) 5/8, 16) 1/6

Step-by-step explanation:

For the first one, you want to find the least common denominator. The least common denominator is 10, so you multiply the numerator and denominator to get 9/10+6/10=15/10. 15/10 is 1.5 or 1 1/2

for the 2nd one you do the same thing. You can get 1/4 to have a denominator of 8 by converting it to 2/8. 7/8-2/8=5/8

finally, you can change 2/3 to 4/6 to get a common denominator. 5/6-4/6=1/6.

What are null hypotheses and alternative hypotheses?

In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

In order to ensure efficient usage of a server, it is necessary to estimate the mean number of concurrent users.

According to records, the average number of concurrent users at 100 randomly selected times is 37.7, with a standard deviation of 9.2.

With this approximation, you can construct the 90% confidence interval the approximate z will be

It is deduced that b and s are not mutually exclusive events as A. No, because the probability of, b intersection s, equals the fraction 5 over 78

Two events are said to be mutually exclusive, if the two events cannot occur simultaneously, hence the intersection of such event defined as (BnS) will be 0.

We can obtain the probability of (BnS) as follows :

n(BnS) = number of students who are both in the band and in the sport team.

Let, this portion of students be represented as x :

(35-x) + (32-x) + x + 16 = 78

35 - x + 32 - x + x + 16 = 78

83 - x = 78

Collect like terms

83 - 78 = x

5 = x

Hence, n(BnS) = 5

Therefore, the probability of B and S will be :

n(BnS) / total number of students

P(BnS) = 5/78

Since, P(BnS) ≠ 0 ; then the events are not mutually exclusive

If 15 postage stamps cost $8.25 then 12 stamps will cost $6.6 if all the stamps cost the same amount.

To calculate the cost of 12 stamps we first calculate the cost of one postage stamp by division.

Since 15 stamps cost $8.25 we can calculate the cost of one stamp by dividing the cost of 15 stamps by 15

cost of one stamp = $8.25 ÷ 15

cost of one stamp = $0.55

Since the cost of one stamp is calculated to be $0.55, we can calculate the cost of 12 stamps by multiplication as follows;

cost of 12 stamps = cost of one stamp × 12

cost of 12 stamps = 0.55 × 12

cost of 12 stamps = $6.6

Probability is the branch of mathematics regarding numerical descriptions of how probable an occasion is to occur, or how possible it is that a proposition is genuine. The probability of an event is a number between zero and 1, wherein, kind of talking, zero suggests the impossibility of the occasion and 1 indicates fact.  

The better the possibility of an occasion, the more likely it is that the event will occur. An easy example is the tossing of an honest (impartial) coin. since the coin is fair, the two results ("heads" and "tails") are both similarly likely; the possibility of "heads" equals the probability of "tails"; and given that no different effects are viable, the chance of either "heads" or "tails" is half off (which could also be written as 0.5 or 50%).

The interval of convergence of the given power series is I=[0, 2/9] and the radius of convergence of power series is R=1

The interval of convergence is:

|9x-1|<1

Or, -1<9x-1<1

Or, 0<9x<2

Or, 0<x<2/9

Given the power series is converges in the interval (0, 2/9)

If x=0, then the power series becomes as shown,

[tex]\sum_{k=1}^{\infty }[/tex](1/(k²+k)([tex]-1^{k}[/tex])

Let [tex]a_{k}[/tex]=([tex]-1^{k}[/tex])(1/(k²+k)

[tex]\lim_{k \to \infty}[/tex]  [tex]a_{k}[/tex]=0 and { [tex]a_{k}[/tex]} sequence is monotone decreasing

Hence by Leibnitz's test,

[tex]\sum_{k=1}^{\infty }[/tex](1/(k²+k)([tex]-1^{k}[/tex]) is convergent

If x=2/9 then the power series becomes [tex]\sum_{k=1}^{\infty }[/tex](1/(k²+k)

Let  [tex]a_{k}[/tex]=(1/(k²+k)and let [tex]b_{k}[/tex]=1/k²

[tex]\sum_{k=1}^{\infty }[/tex] k²/(k²+k)=1 (≠0)

By comparison test, we know that ∑ [tex]a_{k}[/tex] and ∑ [tex]b_{k}[/tex] converge or diverge together.

As  ∑ [tex]b_{k}[/tex]= ∑1/k² converges this implies that  ∑ [tex]a_{k}[/tex]=(1/(k²+k) converges

Hence the interval of convergence of the given power series is,

A provision that ensures performance fees are not earned until the value of a fund exceeds its previous highest level is referred to as High-water mark

A high-water mark is the highest peak in value that an investment fund or account has reached. This term is often used in the context of fund manager compensation, which is performance-based.

The high-water mark ensures the manager does not get paid large sums for poor performance. If the manager loses money over a period, he must get the fund above the high-water mark before receiving a performance bonus

With a high-water mark, the investor pays a fee that only covers the amount the fund earned between the point of entry and its highest level.

An integer's factors are other integers that, when multiplied, give the same result as the original integer. For instance, 33 and 55 are factors of 1515 since 35=1535=15. Knowing what a factor is, we frequently seek to identify an integer's "factorizations".

An integer is represented as the product of its factors in a factorization. The number 11 and the initial integer are always factors, as you can see. This is referred to as a "prime" or complete factorization of 88. The base number, in this case 22, is therefore prime. A prime integer is one with only itself and the number 11 as components. 11 is not a prime number by definition. Prime factors can be used to factor polynomials. Because the elements x+1x+1 and x+2x+2 are irreducible—they only have 11 and themselves as factors—the second factorization is known as the prime factorization. Similar to factoring integers into a product of integers, each smaller than the original, factoring polynomials aims to describe the original polynomial as a product of polynomials of lower degree.

Equations are used to express the data since the 119-foot fence should only contain three sections of the pool (two wide and one long).

First, a calculation that determines the total number of feet in the fence

X + 2Y = 119 (where X is the length and Y is the width)

X = 2Y-3 (because the length is 3 feet less than twice the width)

We proceed to solve for Y using these equations to replace the second equation in the first equation:

X + 2Y = 119

2Y -3 + 2Y = 119

4Y - 3= 119

4Y= 122

Y = 122/4, and Y = 30.5 feet.

We apply the second equation to determine the value of X because we already know that the width equates to 30.5 feet: X = 2Y-3 X = 2 (30.5)-3 X = 61 - 3 X = 58
