Answer:

80y-24z

Step-by-step explanation:

The slope of the line which is perpendicular to the given line 3x+18y=108 is (6).

We already know the equation of a line in slope intercept form y = mx + b and we also know that perpendicular lines that have slopes which are negative reciprocals of each other.

Given a line 13x + 18y=108, this slope intercept form can be written as,

3x + 18y = 108

18y = 108 - 3x

y = (108 /18) - (3/18)x.

y = (6) - 1x/6.

y = -(1/6)x + 6.

Hence the slope of the given line is (-1/6), thus the slope of the line which is perpendicular is (6).

The value of f(4) = 0 by the given graph.

What is graph?

The graph is a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.

Given graph is a straight line, and the equation of a line is given as

y =mx+b

where,

m is the slope,

y is the dependent variable,

we can write it as

f(x)= mx +b

The coordinates are (4,0) and (0,2)

m = 2-0/0-4

m = -1/2

y = -1/2 x +b

we can see the line intersect the y-axis at 0,2

b =2

y = -1/2 x +2

at x =4

f(4) = -2+2=0

Hence, the value of f(4) = 0 in the given graph.

Area of a triangle = (1/2)(b)(h)

Answer: It is used to find the area of a triangle

The formula for the final cost, in terms of the original price y, is:

c(y) = y*(0.88)*(1.03)

Let's define y as the original price of the DVD.

We first apply a discount of the 12% of the price, so the new cost will be:

c(y) = y*(1 - 12%/100%)

c(y) = y*(1 - 0.12)

Then we apply a tax of the 3%, this in increase, then we can write this as:

c(y) = y*(1 - 0.12)*(1 + 3%/100%)

c(y) = y*(1 - 0.12)*(1  + 0.03)

c(y) = y*(0.88)*(1.03)

That is the formula that we could use to determine the final cost.

4.5 hours more will it take for Naomi and Claire to have painted the same number of square feet.

Let the time taken for them to paint equal areas be x hrs.

Naomi  = 2x + 16.5

Clair  = 4x + 7.5

Naomi's area = Clair's area

This is :

2x + 16.5 = 4x + 7.5

4x - 2x = 16.5 -7.5

2x = 9

x = 4.5 hours

The major thing that Ryan should be worried about is the C) high annual depreciation.

Normally, when we buy cars they have so much value but when the cars start being used more often, they tend to depreciate in value due to wear and tear and second value of the product. This tells us that when a car is driven for more miles in a year, it will depreciate greatly.

We are told that Ryan plans to drive about 40 miles to work and back everyday which means that in a year he would have driven thousands of miles. This will lead to a high depreciation.

The expression for the perimeter of the rectangle is 34u - 10 centimeters.

Perimeter of the rectangle:

Perimeter is known as the total length or distance of its boundary on all sides.

The formula that is used to calculate the perimeter of a rectangle is, perimeter of a rectangle = 2(l + w),

where 'l' is the length and

'w' is the width of the rectangle.

Given,

The width of the rectangle is (10u + 3) and the length of the rectangle is (7u - 8)

Now, we need to find the perimeter of the rectangle.

We know that the formula of the rectangle is

Perimeter = 2(l + w)

where l refers the length that is (7u - 8) and w refers the width that is (10u + 3).

Now, we have to apply these values on the formula, then we get,

=> Perimeter = 2((7u -8) + (10u + 3)

When we simplify the equation, then we get,

=> Perimeter = 2((10u + 7u) + (-8 +3))

=> Perimeter = 2(17u - 5)

=> Perimeter = 34u - 10

Therefore, the perimeter of the rectangle is 34u - 10 centimeters.

Given:

lengths of rod, a = 29 and b = 36 ,

angle between them (θ) = 62

we can write area of triangle (Δ) is

 Δ = absinθ/2

Δ =  29*36sin62/2

Δ = 460.89 unit square.

The area of the SAS triangle is 460.89 cm³.

Given data;

Side length (a) = 29

Side length (b) = 36

With an angle of Ф = 62°

Here, it is stated that the triangle is a SAS triangle which is known as the Side Angle Side triangle.

Now, to calculate the area of a given triangle, we use the formula as;

Area = a*b*sinФ/2

From the above formula;

Area of the SAS triangle = a*b*sinФ/2

                                         = [29*36*sin(62°)]/2

                                         = 460.89 cm³

The answer will be, at least as small as that provided by the sample using p-value.

What is the p-value?

Under the premise that the null hypothesis is true, the p-value in null-hypothesis significance testing represents the likelihood of receiving test findings that are at least as extreme as the result actually observed. A severe observed outcome would be highly improbable under the null hypothesis, according to a very small p-value. In academic papers of many quantitative fields, reporting the p-values of statistical tests is standard practice. Misuse of p-value is common and has been a big concern in metascience due to its difficult-to-understand precise meaning.

The probability that a population parameter in a particular statistical model will be less than a given value when the null hypothesis is true is known as the p-value,

And that is also known as a probability value or a measure of significance.

In everyday speech, the term "probability" refers to the likelihood that a specific event (or set of events) will take place, expressed as a number between 0 and 100% or as a linear scale from 0 (impossibility) to 1 (certainty). Statistics is the study of occurrences that follow a probability distribution.

The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

As we already found, the probability of winning for any selection is 1/3 = 0.333.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

a) Let's suppose that player 1 chooses rock, and the selection of player 2 can be thought of as random.

If player 2 randomly selects rock, the result of the game is a draw.

if player 2 randomly selects papers, player 1 loses.

if player 2 randomly selects scissors, player 1 win.

Then we have 3 options with the same probability, that will be:

1/3

This is, the probability of winning is equal to the quotient between the number of outcomes that make player one win (1, in this case, scissors) and the total number of outcomes (3) = 1/3

the probability of a draw is equal to the quotient between the number of outcomes that make a draw (1, in this case, rock) and the total number of outcomes (3) = 1/3

The probability of losing is equal to the quotient between the number of outcomes that make player one lose (1, in this case, paper) and the total number of outcomes (3) = 1/3

Step-by-step explanation:

y = 2x - 2

substitute y with 2x - 2 in the other equation

[tex]x^{2} +y^{2} = 25[/tex]

[tex]x^{2} +(2x-2)^{2} = 25[/tex]

[tex]x^{2} + 4x^{2} -4x-4x+4 = 25[/tex]

[tex]5x^{2} -8x+4=25[/tex]

[tex]5x^{2} -8x-21=0[/tex]

Use the quadratic equation to solve

[tex]\frac{-b(+-)\sqrt{b^{2}-4ac }}{2a}[/tex]

[tex]a = 5\\b = -8 \\c = -21[/tex]

A computer password is required to be 7 characters long.

Note the requirements:

   Repetition of letter or digit is not allowed.

   The order of the letters and digits matters.

Because of that, permutation would be the most suitable way to count the number of possibilities.

There are [tex]P(26,3) = \frac{26!}{(26-3)!} = 26x25x24 = 15,600[/tex] ways to arrange three out of distinct letters (without replacement.)

Similarly, there are [tex]P(10,4) = \frac{10!}{(10-4)!} = 10x9x8x7 = 5,040[/tex] ways to arrange four out of distinct numbers (also without replacement.)

Therefore, there are 15,600 possibilities for the three-letter section of this password, and 5,040 possibilities for the four-digit section. What if these two parts are combined?

Consider: if the first three letters of the password were fixed, then there would be 5,040 possibilities. However, if any of the first three letters was changed, the result would be another 5,040 possibilities, all of which are different from the previous 5,400 possibilities. These two three-letter sections along will give 2 x 5,400 possibilities. Since there are 15,600 three-letter sections like that, there would be 15,600 x 5,400 = 78,624,000 possible passwords in total. That gives the number of possible passwords that satisfy these requirements.
