The variables in the point-slope form of a line (x₁,y₁) is a given point on the line, m the slope of the line and (x,y) is any point on the line.

Given that the variables in the point-slope form of a line.

The general form of the equation of a line is y - y₁ = m (x-x₁) where  m is the slope of line, y₁ and x₁ is any point on the line

It is an equation of degree one x and y represent the coordinate of the point on the line represented in the coordinate plane

m = slope of the line

The general equation of a line is y = mx + c where

m = slope of line

(x₁ , y₁) = it is the given point on the line as data points are represented as (x₁,y₁) , (x₂,y₂) , (x₃,y₃) and so on

(x ,y) = it is any point line where x is any point on the x-axis and y is any point on y-axis

Hence, the variables in the point-slope form of a line where (x₁,y₁) is a given point on the line, m the slope of the line and (x,y) is any point on the line.

The probability that the sample mean will be greater than $1,035 when using a population standard deviation of $227, where the average apartment rent in the U.S. is $1,083, and a random sample of 39 apartments was selected can be calculated using the Z-score.

The formula for calculating the Z-score is given below:

Z = (X - μ) / (σ/√n) where X = the sample mean = $1,035μ =

the population mean

= $1,083σ = the population standard deviation =

$227n = the sample size = 39Substituting these values in the above formula, we have:

Z = (1,035 - 1,083) / (227/√39)Z = -1.65Using the standard normal distribution table, we can find the probability that the Z-score is greater than -1.65. This probability is equal to the area to the right of -1.65 on the standard normal distribution curve.

Using a standard normal distribution table, the area to the right of -1.65 is 0.9505. Therefore, the probability that the sample mean will be greater than $1,035 is 0.9505 or approximately 95%.Hence, the probability that the sample mean will be greater than $1,035 is approximately 95%.

Answer:

\( \displaystyle GH = 2 \sqrt{30} \)

\( \displaystyle FH = 2 \sqrt{10} \)

\( \displaystyle m \angle G = {30}^{ \circ} \)

Step-by-step explanation:

we are given a right angle triangle

it's a 30-60-90 triangle of which FH is the shortest side

remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus

our equation is

\( \displaystyle 2FH=4\sqrt{10}\)

divide both sides by 2

\( \displaystyle\frac{2FH}{2}= \frac{ 4 \sqrt{10} }{2}\)

\( \displaystyle FH =2 \sqrt{10}\)

in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle

as we want to figure out GH we'll use sin function

remember that,

\( \displaystyle \sin( \theta) = \frac{opp}{hypo} \)

let our opp, hypo and \(\theta\) be GH, 4√10 and 60° respectively

thus substitute:

\( \displaystyle \sin( {60}^{ \circ} ) = \frac{GH}{4 \sqrt{10} } \)

recall unit circle:

\( \displaystyle \frac{ \sqrt{3} }{2} = \frac{GH}{4 \sqrt{10} } \)

cross multiplication:

\( \displaystyle 2 GH = 4 \sqrt{10} \times \sqrt{3} \)

simplify multiplication:

\( \displaystyle 2 GH = 4 \sqrt{30} \)

divide both sides by 2:

\( \displaystyle GH = 2 \sqrt{30} \)

Recall that, the sum of the interior angles of a triangle is 180°

therefore,

\( \displaystyle m \angle G + {60}^{ \circ} + {90}^{ \circ} = {180}^{ \circ} \)

simplify addition:

\( \displaystyle m \angle G + {150}^{ \circ} = {180}^{ \circ} \)

cancel 150° from both sides

\( \displaystyle m \angle G = {30}^{ \circ} \)

The rotation is 180 degrees in clockwise direction.

What is rotation?

The angle of rotation is a measurement of the amount, of namely angle, that a figure is rotated about a fixed point, often the center of a circle.

The complete question is:

Angie’s rotation maps triangle XYZ to triangle X’Y’Z’.

X(3, –6) maps to X’(–3, 6)

Y(1, –2) maps to Y’(–1, 2)

Z(–1, –5) maps to Z’(1, 5)

Which describes the rotation?

If we look at the coordinates carefully then we can see that the sign of the coordinates have been changed.

As, (x,y) to (-x, -y)

Hence, the rotation is  180 degrees rotation (x,y) to (-x, -y) in clockwise rotation.

1) A translation of 3 units down, option D.

2) The vertex moves 3 units down.

3) The new range is y ≥ -3, correct option is C.

For a function f(x) a vertical shift of N units is written as:

g(x) = f(x) + N

In this case, we have:

f(x) = |x|

h(x) = |x| - 3

Then h(x) = f(x) - 3

This is a shift of 3 units down, the correct option is D.

How is the vertex affected?

The vertex is translated 3 units down, like the whole graph of the function.

How is the range affected?

The vertex defines the minimum of the range, so if the vertex goes 3 units down, then the range also does, the new range will be:

y ≥ -3.

Answer:

Below

Step-by-step explanation:

The plane's distance is the hypotenuse of a right triangle with legs of

(50 -20)mi = 30 miles     and     30500 - 18000 = 12500 ft

                             for consistent units  12500ft/5280ft/mile = 2.36742 miles

Now just use Pythagorean theorem

Hypotenuse^2 = leg1^2 + leg2^2

               h^2    = 30^2 + 2.36742^2

                   h = ~ miles 30.093 miles  ( note that the vertical descent distance does not matter much)

Answer:

she saved 6$ because 15% off 40=34 40-34=6

The ratio 83% is greater than the ratio 41/50.

To compare the two ratios, one written as a fraction (41/50) and the other as a percent (83%), we need to convert them to the same format.

To compare fractions and percentages directly, we can convert the fraction to a percentage or the percentage to a fraction.

Converting the fraction to a percentage:

To convert the fraction 41/50 to a percentage, we divide the numerator (41) by the denominator (50) and multiply by 100:

(41/50) * 100 = 82%

Converting the percentage to a fraction:

To convert the percentage 83% to a fraction, we divide the percentage by 100:

83/100

Now that we have both ratios in fraction form, we can directly compare them.

41/50 is equivalent to 82/100, and 82/100 is less than 83/100.

Therefore, the ratio 83% is greater than 41/50

A square root of a number x is a number y such that y2 = x; in other words, a number y who's square and the result of multiplying the number by itself, or y ⋅ y, is x.

Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √where the symbol √ is called the radical sign.

Every positive number x has two square roots: √ which is positive, and -√ which is negative. The two roots can be written more concisely using the ± although the principal square root of a positive number is only one of its two square roots, the designation "the square root" is often used to refer to the principal square root.

Answer: 6 in ; 2nd option

Step-by-step explanation: Since the formula for the volume of a cube is \(s^3\) where s represents a side length, you can just take the cube root of the volume to find each side length,

\(\sqrt[3]{216}\\ =6\)

Therefore, each side is 6 in.

Let's assume the speed of the plane in still air is represented by 'p' (in mph).

When the plane is flying with the wind, its effective speed increases by the speed of the wind. So the speed of the plane with the wind is 'p + 10' (in mph).

When the plane is flying against the wind, its effective speed decreases by the speed of the wind. So the speed of the plane against the wind is 'p - 10' (in mph).

The time taken to travel a certain distance is given by the formula: Time = Distance / Speed.

Given that the length of time is the same for both situations, we can set up the following equation:

495 / (p + 10) = 440 / (p - 10)

We can cross-multiply to solve for 'p':

495(p - 10) = 440(p + 10)

495p - 4950 = 440p + 4400

495p - 440p = 4400 + 4950

55p = 9350

p = 9350 / 55

p ≈ 170

Therefore, the speed of the plane in still air is approximately 170 mph.
