The midpoint of PQ is M =(1,-5) . One endpoint is P= (-3, -2) .
Find the coordinates of the other endpoint, Q .

Answer:

Step-by-step explanation:

You want the costs of an oscilloscope and a multimeter when the sum of their costs is $574, and the difference of their costs is $356.

Let o and m represent the costs of the oscilloscope and multimeter, respectively. Then the costs can be described by ...

  o +m = 574

  o -m = 356

Adding these two equations gives ...

  2o = (574+356) = 930

  o = 465 . . . . . . . . . . . . divide by 2

Subtracting the second equation from the first gives ...

  2m = 574 -356 = 218

  m = 109 . . . . . . . . . . . . divide by 2

The oscilloscope costs $465; the multimeter costs $109.

In arithmetic equations, the identical sign (=) is used to denote the equivalence of two assertions. It is demonstrated that using mathematical methods, which have acted as manifestations of reality, it is feasible to compare different numerical factors. For fact, the equal sign splits the number 12 into two separate parts, even if the answer is y + 6 = 12. It is possible to determine how many letters are also present on either end of this character.

Here,

The equation for the total cost of a party at this venue for p people is:

C = 20p + 70

To graph this equation, you can plot two points and draw a line passing through them.

One point can be the y-intercept (0, 70), which represents the fixed event fee charged by the venue.

The second point can be any other point on the line. For example, when there are 3 people at the party, the total cost would be:

C = 20(3) + 70 = 110

So another point on the line would be (3, 110). Plotting these two points and drawing a line passing through them will give you the graph of the total cost as a function of the number of people at the party.

After evaluating these expression it seems to be the option (a) math.hypot(3,4) == math.sqrt(25) evaluate that is True

The math.hypot function calculates the Euclidean distance between two points in a 2D space, which is equivalent to the length of the hypotenuse of a right triangle with sides of length a and b (where a and b are the arguments to math.hypot).

In this case, math.hypot(3, 4) calculates the length of the hypotenuse of a right triangle with sides of length 3 and 4, which is equal to 5.

The expression math.sqrt(25) calculates the square root of 25, which is equal to 5. Since math.hypot(3, 4) and math.sqrt(25) both evaluate to 5, the expression math.hypot(3, 4) == math.sqrt(25) evaluates to True.

The other expressions are not evaluating to True:

Step-by-step explanation:

We have the following information:

AB = 2DH

DH = 2BE or BE = DH/2

The area of square ABCD = (2DH)² = 4DH²

The area of square BEFG = BE² = (DH/2)² = DH²/4

The area of square DHFJ = DH²

Area of the unshaded region

When constructing bins for a frequency distribution, it is important to have equal widths, choose the number of bins based on the sample size, and consider outliers in the data.

A frequency distribution is a representation of data that shows the number of observations in each category or bin.

One of the most important principles is to have an equal number of observations in each bin. This is known as having equal widths for the bins.

To calculate the width of a bin, divide the range of the data by the number of bins desired. The range is then divided into equal parts, each of which becomes a bin width.

Another principle is to have the number of bins chosen based on the sample size.

A rule of thumb is to have at least five observations in each bin, but more bins may be necessary for larger samples.

Additionally, the choice of bin width can also be influenced by outliers in the data. If there are extreme values in the data, it may be necessary to create a separate bin for those values, so they do not dominate the frequency distribution.

Answer:

The light beam will hit the ground at a distance of _756_ ft ahead of the car

Step-by-step explanation:

Let x be the distance in feet ahead of the car at which the light beam hits the ground.

Since the light beam drops 2 inches for each 21 feet measured horizontally, we can write the relationship between the height of the light beam and the distance x as:

24 - (2/21)x = 0

Solving for x, we get:

x = (21/2) * 24

x = 756

So the light beam will hit the ground 756 feet ahead of the car.

Step-by-step explanation:

Where the OADB is a sector of a circle, and Angle AOB  = 80°, and the Radius of OB = 12cm,:

A circular sector (symbol: ) is the piece of a disk (a closed region circumscribed by a circle) contained by two radii and an arc, where the smaller area is known as the minor sector and the bigger as the major sector.

Given m∠AOB = 98°, OB = OA = 25cm (The radii are congruent) Thus,

m∠OAB = m∠OBA,

m∠OAB = (180 - 98) /2

m∠OAB = 41°

In the Right Triangle OBC, OB = 25cm, m∠OBC = 41°

Hence,

OC /OB = Sin ∠OBC ,
OC = OB (Sin ∠OBC )

= 25 * Sin41°

= 16.4cm; thus,

OC = 16.4cm

Where BC/OB = Cos ∠OBC,

BC = OB ( Cos ∠OBC)

= 25 * Cos 41° Thus,

BC = 16.4cm


The area of the ΔOAB = 1/2 * OA * OB * Sin98°
= 1/2 * 25 * 25 * Sin 98°

= 309.5cm²


The area of the Sector OADB = (98°/360°) * π * 25²

= 0.2722222222 * 3.14 * 25²

= 0.2722222222 * 3.14 * 252

The rate of change of the profit when the item price is $30 is $3600 per dollar increase in price.

Two or more expressions with an Equal sign is called as Equation.

Let's call the number of items sold at a price of $p as x(p).

Based on the information given, we can write an equation for x(p) as:

x(p) = 2000 - 400(p - 30)

The profit from selling the items at a price of $p is given by the product of the number of items sold and the price:

Profit(p) = x(p)×p

Taking the derivative of the profit function with respect to the price, we can find the rate of change of the profit:

dProfit/dp = dx/dp×p + x(p)

= -400 p + 400 ( 30) + 2000 - 400(p - 30)

= -400 p + 12000

When p = 30, the rate of change of the profit is:

dProfit/dp = -400(30 )+ 12000

= 3600

So the rate of change of the profit when the item price is $30 is $3600 per dollar increase in price.

Hence,  the rate of change of the profit when the item price is $30 is $3600 per dollar increase in price.

1.             The pattern that I observe in the table above is that the fixed perimeter of these rectangles are 24 meters, and that the graph to represent this function is in the shape of a parabola with a vertex point at (6, 36). As for comparing the patterns to the graph in question A, assuming you're referring to the question I just answered, the graphs both are parabola shaped, with a vertex point and two zeros, one of them being the same at the origin of the coordinate plane (0, 0).

2.            The fixed perimeter for the rectangles represented by this table is 24 meters because if you want to find the fixed perimeter of these rectangles, you can pick any point that is not a zero point of the graph. For example, if the length of a rectangle is 1 meter, and the area is 11 [tex]m^2[/tex], we know the width would be 11 meters. Using this information, we know that the fixed perimeter would be (1 + 11) × 2 = 12 × 2 = 24 meters.

3.            The greatest area possible for a rectangle with a perimeter of 24 meters would be 36 [tex]m^2[/tex] because we can graph these points to form a parabola that represents this situation, and the vertex point of this graph would be the greatest area possible out of all the possible combinations of length and width that would still fit the criteria of having a perimeter of 24 meters.

              Based on the table, the vertex point of the graph would be (6, 36), therefore the greatest area possible for a rectangle with this perimeter would be 36 [tex]m^2[/tex]. As for the dimensions of this rectangle, we know the length is 6 meters, and the area is 36 [tex]m^2[/tex], so the width would be 36 ÷ 6 = 6 meters. Therefore the dimensions of this rectangle would be 6 meters in length and 6 meters in width.

a) The probability of having at least 1 rotten strawberry among the 5 is 0.262.

b) 1 strawberry must be picked so that the probability of having exactly 2 rotten strawberries among them equals 2/35.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The probability that Kyle selects exactly k rotten strawberries among the five she randomly picks is -

P( exactly k rotten strawberries) = [tex]\frac{(^2c_k)(^{34}c_{5-k}) }{^{36}c_5}[/tex]

since if she picks k of the 2 rotten strawberries, Kyle must also select 5 - k of the 36 -2 = 34 good strawberries.

Therefore, the probability that Kyle picks at least one rotten strawberry is -

P(at least 1 rotten strawberry) = P(exactly 1 rotten strawberry) + P(exactly 2 rotten strawberries)

P(at least 1 rotten strawberry) =[tex]\frac{(^2c_1)(^{34}c_{4}) }{^{36}c_5} + \frac{(^2c_2)(^{34}c_{3}) }{^{36}c_5}[/tex]

P(at least 1 rotten strawberry) = [(2 × 46376) / 376992] + [(1 × 5984) / 376992]

P(at least 1 rotten strawberry) = (92752 / 376992) + (5984 / 376992)

P(at least 1 rotten strawberry) = 0.246 + 0.016

P(at least 1 rotten strawberry) = 0.262

The probability of selecting exactly 2 rotten strawberries among n is

P(exactly 2 rotten strawberries) = [tex]\frac{(^2c_2)(^{34}c_{n-2}) }{^{36}c_n} = \frac{(^{34}c_{n-2}) }{^{36}c_n}[/tex]

The value for n is 2/35.

P(exactly 2 rotten strawberries) =[tex]\frac{(^{34}c_{\frac{-33}{35}}) }{^{36}c_{\frac{2}{35} }}[/tex]

P(exactly 2 rotten strawberries) = 1 / 1

P(exactly 2 rotten strawberries) = 1
