Answer: 12.5

Step-by-step explanation:

Let's first find the perimeter.

P = 2l + 2w

Since Mr.Wilson's perimeter equals Ms.Krietz's, we can use the same number for both.

P = 2(30)+2(20) = 100

Since the length of Ms.Krietz's homeroom is 1.25x the length of Mr.Wilson's, we can substitute that

l = 1.25(30) = 37.5

100 = 2(37.5) + 2w

100 = 75 + 2w

25 = 2w

w = 12.5

{(-4, 3), (5, -1), (0, 2), (x, y)} set of ordered pairs (1, -3) could represent a linear function.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

For option A:

m=1+2/3-1=3/2

m=3/2

m=7-4/8-5=3/3=1

Answer:

sinθ = -3/5, Quadrant IV (Option B)

Step-by-step explanation:

Let's first find the sine

cosθ = adj./hyp.

Pythagorean theorem (in terms of right triangle trig) = (opp)^2 + (adj)^2 = (hyp)^2

Plug in the adjacent and hypotenuse

(opp.)^2 + 16 = 25

solve for the opposite side

opp. = 3

To find the quadrant, recall the sin <0, so the sin has to be negative.

So, your sine value is -3/5.

Sine is negative at Quadrants III and IV, so eliminate C and D.

Since your cosine value is positive, it is at Quadrant IV (Cosine is positive at the first and fourth quadrants.)

Therefore, Option B is correct.

[tex]\sqrt{x^5}\cdot \sqrt{x^{10}}\implies \sqrt{x^5\cdot x^{10}}\implies \sqrt{x^{5+10}}\implies \sqrt{x^{15}}\implies \sqrt{x^{14+1}} \\\\\\ \sqrt{x^{14}\cdot x^1}\implies \sqrt{x^{7\cdot 2} x}\implies \sqrt{(x^7)^2 x}\implies x^7\sqrt{x}[/tex]

The claim might be considered to be inaccurate because Joseph's actual average quiz grade for math is 85

When given a set of numbers of variables, the average variable can be found by dividing the sum of the variables by the number of variables in the set.

For Joseph therefore, the average of the quiz grades that he has from his math quizzes would be :
= ( 81 + 89 + 80 + 84 + 89 + 85 ) / 6

= 508 / 6

= 84. 6

= 85

This shows that Joseph's claim of an average of 89 in his math quizzes is therefore inaccurate.

Most likely, what Joseph thought he meant was that the mode of his math quizzes was 89 as the mode refers to the variable that appears the most in a set.

The maximum number of full pizzas she can make if Avery had 7 pounds of cheese available, and she needs 3/5 pounds of cheese to make each pizza, is 11.

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

Avery had 7 pounds of cheese available, and she needs 3/5 pound of cheese to make each pizza,

Calculate the number of pizzas she can make as shown below,

The number of pizzas = total cheese/cheese required to make one pizza

Step-by-step explanation:

The null hypothesis is a statement of no change, no effect, or no difference.

The null hypothesis is a statement or assumption that there is no relationship between two variables or no difference between two groups, and any observed differences are likely due to chance. It is often denoted as H0. In scientific research, the null hypothesis is usually tested against an alternative hypothesis, which proposes that there is a relationship or difference.

For example, in a medical study, the null hypothesis might be that a new treatment has no effect on a certain disease, while the alternative hypothesis is that the treatment does have an effect. The researcher would then collect data and use statistical methods to test the null hypothesis against the alternative hypothesis.

It's important to notice that a failure to reject the null hypothesis doesn't mean the null hypothesis is true, it only means that there isn't enough evidence to reject it.

Step-by-step explanation:

Given information:

For any complex number  [tex]z=a+bi[/tex], the complex conjugate of the number is defined as  [tex]z^*=a-bi[/tex].  

If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.

Therefore, if P(x) is a polynomial, and i is a root of f(x)=0, then its complex conjugate -i is also a root of P(x)=0.

Similarly, if P(x) is a polynomial, and -5+7i is a root of f(x)=0, then its complex conjugate -5-7i is also a root of P(x)=0.

Therefore, the polynomial in factored form is:

[tex]P(x)=x(x-i)(x-(-i))(x-(-5+7i))(x-(-5-7i))[/tex]

[tex]P(x)=x(x-i)(x+i)(x+5-7i)(x+5+7i)[/tex]

The precentile for a student in the class who studies 8 hours a week is 5.74%.

To find the percentile for a student who studies 8 hours a week, we need to first standardize the student's study time by subtracting the mean study time and dividing it by the standard deviation of study time. This will give us the student's z-score. We can then look up the student's z-score in a standard normal table to find the percentile.

The student's z-score is (8 - 9.92) / 4.54 = -1.67.

Looking up -1.67 in a standard normal table, we find that the percentile is about 5.74%. This means that about 5.74% of the students in the class studied for less than 8 hours per week.

As per the given standard deviation, the percentile for a student in the class who studies 8 hours a week is 50.80%

The term standard deviation in math is known as a measure which shows how much variation from the mean exists.

Here we have given that in one statistics course students reported studying an average of 9.92 hours a week with a standard deviation of 4.54.

Through this details, we have identified that the value of the following are given that,

=> weekly study time = 10 hours

=> average study time = 9.92 hours

=> standard deviation = 4.54 hours

Then the formula to calculate the Test statistic is written as

=> z = (weekly study time - average study time)/standard deviation

Apply the values on it, then we get

=> z = (10 - 9.92)/4.54

=> z = 0.08/4.54 = 0.02

While we take the value of z table, then we get the Cumulative area of the test statistic is 0.5080.

And the percentile is calculated by multiply the value by 100 as,

By using the bubble sort algorithm, a total of 9 passes/scans will be there.

When an array or list of items has to be rearranged, a sorting algorithm is used to compare the elements and sort the elements in the array or list. In each data structure, the new order of the items is determined using the comparison operator.

The simplest sorting method is called Bubble Sort, and it involves periodically exchanging nearby components if they are arranged incorrectly. Since the average and worst-case time complexity of this approach is relatively high, it is not appropriate for huge data sets.

According to the question, we have

Total number of elements we are having, i.e., n = 10

The total number of passes = n-1 = 10 - 1 = 9
