draw a quadrilateral that does not belong, then explain why. What should I draw and write?​

The side length of a cube with a volume of 64 mm^3 is found by taking the cube root of the volume, which is 4 mm.

To find the side length of a cube with a given volume, you apply the formula for the volume of a cube, which is V = s3, where V is the volume and s is the side length of the cube. Since the volume of the cube is given as 64 mm3, you need to take the cube root of 64 to find the side length.

The steps are as follows:

Substitute the value into the formula: V = s^3, so 64 mm3 = s3.

Undo the cube by applying the cube root: s = ∛64 mm3, which simplifies to s = 4 mm.

Therefore, the side length of the cube is 4 mm.

Answer:

B = 612.2 ft

Step-by-step explanation:

Solution:-

- The elevation of person, H = 235 ft

- The angle of depression, θ = 21°

- We will sketch a right angle triangle with Height (H), and Base (B) : the boat's distance to the edge of the cliff and the angle (θ) between B and the direct line of sight distance.

- We will use trigonometric ratios to determine the distance between boat and the edge of the cliff, using tangent function.

                             tan ( θ ) = H / B

                             B = H / tan ( θ )

                             B = 235 / tan ( 21 )

                             B = 612.2 ft    

Answer:

The distance of the boat from the edge of the cliff is 655.75 ft

Distance of the boat from the base of the cliff is 251.72 ft

Step-by-step explanation:

Height of person above sea level = 235 ft

Angle of depression of sight to the boat from the person = 21°

Therefore, based on similar angle between person and angle of depression and the boat with angle of elevation we have,

Angle of elevation of the location of the person as sighted from the boat θ = 21°

Distance from the edge of the cliff of the boat is then given by;

[tex]Sin\theta = \frac{Opposite \, side \, to\, angle}{Hypothenus\, side \, of\, triangle} = \frac{Height\, of\, person\, above \, ses \, level}{Distance\, of\, boat\, from \, edge\, of \, cliff}[/tex]

[tex]Sin21 =\frac{235}{Distance\, of\, boat\, from \, edge\, of \, cliff}[/tex]

[tex]Distance\, of\, boat\, from \, edge\, of \, cliff=\frac{235}{Sin21 } = \frac{235}{0.358} = 655.75 \, ft[/tex]

Distance of the boat from the base of the cliff is given by

[tex]Distance\, of\, boat\, from \, base\, of \, cliff=\frac{235}{cos21 } = \frac{235}{0.934} = 251.72 \, ft[/tex].

Answer:

Price decrease = 24 %

Step-by-step explanation:

Given:

Initial price of the 60 inch television = $ 1050

Final price of the same television = $ 798

We have to find by what percent did the price of the television decrease.

Let the percent decrease be "x".

Formula to be used:

⇒ [tex]Percent\ decrease =\frac{(Initial\ price) - (Final\ price)}{Initial\ price}\times 100[/tex]

Using the above formula:

And plugging the values.

⇒ [tex]\%\ decrease =\frac{(Initial\ price) - (Final\ price)}{Initial\ price}\times 100[/tex]

⇒ [tex]\%\ decrease =\frac{(1050) - (798)}{1050}\times 100[/tex]

⇒ [tex]\%\ decrease =\frac{252}{1050}\times 100[/tex]

⇒ [tex]\%\ decrease =0.24\times 100[/tex]

The set 2 contains an outlier.

The range measure of spread was most impacted by the outlier.

A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.

Given:

Set 1: 8, 15, 13, 7, 11, 17, 13

Median = 13

Lower quartile = 8

Upper quartile = 15

Range = 10

Interquartile range = 7

And Set 2: 8, 15, 13, 7, 11, 17, 13, 100

Median = 13

Lower quartile = 9.5

Upper quartile = 16

Range = 93

Interquartile range = 6.5

Set two contains the value 100 as an outlier.

The range is the component of spread that was most adversely affected by the outlier.

This is due to the fact that set two's median, quartiles, and interquartile range are all closely clustered together, but the range is 93, which is extremely disproportional high compared to any of those other numbers.

Therefore, set 2 contains an outlier.

R(t)=401−10t

Step-by-step explanation:

Given the data, there appears to be a negative linear relationship between time and radius as the balloon deflates. This suggests a model of the form R(t) = a - bt best fits the data.

The subject matter here is a Mathematical topic related to model fitting - a statistical method that estimates the relationship between variables. In this case, the variables are Time (t) and radius (R). From the given data, it seems that the radius is reducing as the time increases, which likely indicates a negative linear relationship.

We can also observe that the data points reduce at a constant rate (e.g., it goes down by 50 cm every 5 seconds initially), which further supports the idea of a linear model.

Therefore, considering this rate of change and the mathematical relationship between the variables, a linear model of the form R(t) = a - bt (where a is the initial radius and b is the rate of decrease) would likely be the best option.

Answer:

Niles and Bob were traveling for 6 hours.

Step-by-step explanation:

The speed or rate at which an object is moving can be computed using the formula:

[tex]s=\frac{d}{t}[/tex]

Here:

s = speed

d = distance traveled

t = time taken

It is provided that Niles and Bob sailed at the same time for the same length of time.

Speed of Niles sailboat is, s₁ = 6 mph.

Distance traveled by Niles' sailboat is, d₁ = 36 miles.

Speed of Bob's sailboat is, s₂ = 16 mph.

Distance traveled by Bob's sailboat is, d₂ = 96 miles.

It took both Niles and Bob the same time to travel the respective distance.

Compute the time it took Niles to travel 36 miles at 6 mph speed as follows:

[tex]t_{1}=\frac{d_{1}}{s_{1}}[/tex]

   [tex]=\frac{36}{6}\\=6[/tex]

It took Niles 6 hours to travel 36 miles at 6 mph speed.

Compute the time it took Bob to travel 96 miles at 16 mph speed as follows:

[tex]t_{2}=\frac{d_{2}}{s_{2}}[/tex]

   [tex]=\frac{96}{16}\\=6[/tex]

It took Bob 6 hours to travel 96 miles at 16 mph speed.

Thus, Niles and Bob were traveling for 6 hours.

Given:

Given that the triangle.

Let the length of the side a be 10 cm.

Let the length of the side b be 13 cm.

Let the measure of ∠C is 105°

We need to determine the area of the triangle.

Area of the triangle:

The area of the triangle can be determined using the formula,

[tex]A=\frac{1}{2} a b \ sin \ c[/tex]

Substituting a = 10, b = 13 and ∠C = 105°, we get;

[tex]A=\frac{1}{2}(10)(13) \ sin \ 105[/tex]

Simplifying, we get;

[tex]A=\frac{1}{2}(10)(13)(0.966)[/tex]

[tex]A=\frac{1}{2}(125.58)[/tex]

[tex]A=62.79 \ cm^2[/tex]

Rounding off to 1 decimal place, we have;

[tex]A=62.8 \ cm^2[/tex]

Thus, the area of the triangle is 62.8 cm²

The area of the triangle is 65 square centimeters when rounded to one decimal place.

To find the area of a triangle, you can use the formula:

[tex]Area = (\frac{1}{2} ) \times base \times height[/tex]

In this case, you have a base of 13 cm and a height of 10 cm. Plug these values into the formula:

[tex]Area =(\frac{1}{2} ) \times 13 cm \times 10 cm[/tex]

[tex]Area = (\frac{1}{2}) \times 130 cm^2[/tex]

Now, calculate the area:

[tex]Area = 65 cm^2[/tex]

So, the area of the triangle is 65 square centimeters when rounded to one decimal place.

Final answer:

Susie was 20 meters behind Andy when he reached the finish line in the 100-meter race.

Explanation:

To determine how many meters Susie was behind Andy at the moment Andy reached the finish line during the 100-meter race, let's consider the information given:

Andy finished the race.

Blaise was 10 meters behind Andy at that moment.

Susie was 10 meters behind Blaise when Blaise finished the race.

When Blaise reached the finish line, Andy would have already finished since Blaise was behind by 10 meters. However, at the moment Andy finished, Susie was also behind Blaise, who was 10 meters from finishing. Hence, Susie was 10 meters (the distance Blaise was behind Andy) + 10 meters (the distance Susie was behind Blaise at her finish) = 20 meters behind Andy when he finished the race.

In conclusion, Susie was 20 meters behind Andy when Andy reached the finish line.

Answer:

They'll build 66 cars in those conditions.

Step-by-step explanation:

In this case we can use a compounded rule of three to solve the problem. We need to set it up as shown bellow:

160 workers -> 32 cars -> 2 hours

220 workers -> x cars -> 3 hours

If the number of workers rise, then we expect the number of cars to rise aswel, so they're directly proportional. If the number of hours worked increase we can expect the number of cars to increase aswell, so they're directly proportional. We can now set the fractions:

(160*2)/(220*3) = 32/x

320/660 = 32/x

x = (32*660/320) = 66 cars

They'll build 66 cars in those conditions.

Final answer:

To find the number of cars that 220 workers can produce in 3 hours, we can use the joint variation equation and the given information. By solving for the constant of variation, we can substitute the new values to find the answer.

Explanation:

To solve this problem, we can set up a joint variation equation:

cars = k * workers * time

Given that 160 workers can produce 32 cars in 2 hours, we can substitute these values into the equation:

32 = k * 160 * 2

Solving for k, we find that k = 0.1.

Now, we can use this value of k to find the number of cars that 220 workers can produce in 3 hours:

cars = 0.1 * 220 * 3

cars = 66

Therefore, 220 workers can produce 66 cars in 3 hours.

Answer:

316

Step-by-step explanation:

The question has a little problem:

"the probability that they chose the same book is m n for relatively prime positive integers m and n. Compute 100m + n."

The correct sentence:

the probability that they chose the same book is "m/n" for relatively prime positive integers m and n.

Total number of books = 4

We have:

Number of 200page book = 1

Number of 400page book = 1

Number of 600page book = 1

Number of 800page book = 1

Probability of picking same book:

Velma read page 122 of her book Daphne read page 304 of her book

If it is same book, it must contain atleast 400page.

Therefore, 400page, 600page and 800 page would be considered in the probability.

Pr(one 400page) = 1/4

Pr(picking two 400page) = 1/4 * 1/4 = 1/16

Pr(one 600page) = 1/4

Pr(picking two 600page) = 1/4 * 1/4 = 1/16

Pr(one 800page) = 1/4

Pr(picking two 800page) = 1/4 * 1/4 = 1/16

Pr(picking same book page)=

Pr(picking two 400page) or Pr(picking two 600page) or Pr(picking two 800page)

= Pr(picking two 400page) + Pr(picking two 600page) + Pr(picking two 800page) = 1/16+ 1/16+ 1/16

Pr(picking same book page)= 3/16

This answer satisfies the probability as m/n for relatively prime positive integers m and n.

Two numbers are said to be relatively prime integers if the only positive integer that divides both of them is 1. It means the numerator and denominator of the fraction have been reduced to the lowest form.

m/n = 3/16

m = 3, n= 16

100m + n = 100(3) + 16

= 316

Answer:

100m+n = 6425

Step-by-step explanation:

Let X be the book Velma picks and Y the book that Daphne picks. Note that X and Y are independent and identically distributed, so for computations, i will just focus on X for now.

Lets denote with A, B, C and D the books with 200, 400, 600 and 800 pages respectively.

Note that, without any restriction P(X=A) = P(X=B) = P(X=C) = P(X=D) = 1/4. However, if we also add the condition that R = 122, where R is the page picked, we will need to apply the Bayes formula. For example,[tex]P(X=A|R=122) = \frac{P(R = 122|X=A)*P(X=A)}{P(R=122)}[/tex]

P(X=A) is 1/4 as we know, and the probability P(R=122|X=A) is basically the probability of pick a specific page from the book of 200 pages long, which is 1/200 (Note however, that if he had that R were greater than 200, then the result would be 0).

We still need to compute P(R=122), which will be needed in every conditional probability we will calcultate. In order to compute P(R=122) we will use the Theorem of Total Probability, in other words, we will divide the event R=122 in disjoint conditions cover all possible putcomes. In this case, we will divide on wheather X=A,  X=B, X=C or X=D.

[tex]P(R=122) = P(R=122 | X=A)*P(X=A) + P(R=122|X=B)*P(X=B)+P(R=122|X=C)*P(X=C)+P(R=122|X=D)*P(X=D) = 1/200 * 1/4 + 1/400*1/4 + 1/600*1/4+1/800*1/4 = 1/4*(12/2400 + 6/2400 + 4/2400 + 3/2400) = 1/384[/tex]

Thus, P(R=122) = 1/396

With this in mind, we obtain that

[tex]P(X=A|R=122) = \frac{\frac{1}{200}*\frac{1}{4}}{\frac{1}{396}} = \frac{384}{800} = \frac{12}{25}[/tex]

In a similar way, we can calculate the different values that X can take given that R = 122. The computation is exactly the same except that for example P(R=122|X=B), is 1/400 and not 1/200 because B has 400 pages.

[tex]P(X=B|R=122) = \frac{\frac{1}{400}*\frac{1}{4}}{\frac{1}{384}} = \frac{384}{1600} = \frac{6}{25}[/tex]

[tex]P(X=C|R=122) = \frac{\frac{1}{600}*\frac{1}{4}}{\frac{1}{384}} = \frac{384}{2400} = \frac{4}{25}[/tex]

[tex]P(X=D|R=122) = \frac{\frac{1}{800}*\frac{1}{4}}{\frac{1}{384}} = \frac{384}{3200} = \frac{3}{25}[/tex]

We can make the same computations to calculate the probability of Y = A,B,C or D, given that R=304. However, P(Y=A|R=304) will be 0 because A only has 200 pages (similarly, P(R=304|Y=A) = 0, R=304 and Y=A are not compatible events). First, lets compute the probability that R is 304.

[tex]P(R=304) = P(R=304|Y=A)*P(Y=A)+P(R=304|Y=B)*P(Y=B)+P(R=304|Y=C)*P(Y=C)+P(R=304|Y=D)*P(Y=D) = 0+1/400*1/4+1/600*1/4+1/800*1/4 = 13/9600[/tex]

Thus, P(R=304) = 13/9600. Now, lets compute each of the conditional probabilities

[tex] P(Y=A|R=304) = 0[/tex] (as we stated before)

[tex]P(Y=B|R=304) = \frac{\frac{1}{400}*\frac{1}{4}}{\frac{13}{9600}} = \frac{9600}{1600*13} = \frac{6}{13}[/tex]

[tex]P(Y=C|R=304) = \frac{\frac{1}{600}*\frac{1}{4}}{\frac{13}{9600}} = \frac{9600}{2400*13} = \frac{4}{13}[/tex]

[tex]P(Y=D|R=304) = \frac{\frac{1}{800}*\frac{1}{4}}{\frac{13}{9600}} = \frac{9600}{3200*13} = \frac{3}{13}[/tex]

We want P(X=Y) given that [tex] R_x = 122 [/tex] and [tex] R_y = 304 [/tex] (we put a subindex to specify which R goes to each variable). We will remove the conditionals to ease computations, but keep in mind that we are using them. For X to be equal to Y there are 3 possibilities: X=Y=B, X=Y=C and X=Y=D (remember that Y cant be A given that [tex] R_y = 304). Using independence, we can split the probability into a multiplication.

[tex] P(X=Y=B) = P(X=B|R=122)*P(Y=B|R=304) = \frac{6}{25} * \frac{6}{13} = \frac{36}{325} [/tex]

[tex] P(X=Y=C) = P(X=C|R=122)*P(Y=C|R=304) = \frac{4}{25}*\frac{4}{13} = \frac{16}{325} [/tex]

[tex] P(X=Y=D) = P(X=D|R=122)*P(Y=D|R=304) = \frac{3}{25}*\frac{3}{13} = \frac{9}{325} [/tex]

Therefore

[tex] P(X=Y) = \frac{36}{325} + \frac{16}{325} + \frac{9}{325} = \frac{61}{325} [/tex]

61 is prime and 325 = 25*13, thus, they are coprime. Therefore, we conclude that m = 61, n = 325, and thus, 100m+n = 6425.

You can construct a pie chart by calculating the percentage each item contributes to the total in your table. Each percentage point represents a slice of the pie, with the size of the slice proportional to the percentage of the total.

In a pie graph, each slice of the pie represents a share of the total, or a percentage. For example, 50% would be half of the pie and 20% would be one-fifth of the pie. The pie graphs allow you to get a feel for the relative size of the different historical data sets.

To create your pie chart based on your table, you will want to find the percentage of the total that each holiday destination in your table represents. Once you've calculated these percentages, you can begin creating your pie chart. Each slice of your pie will correlate to a holiday destination, with the size of the slice representative of the percentage of people that chose that destination.

Answer:

Brad picked 130 apples. Andy picked 45 apples. Krystal picked 115 apples.

Step-by-step explanation:

B = 2Y                A = Y - 20            K = Y + 50        B + A + K + Y = 355

130 = 2(65)        45 = 65 - 20        115 = 65 + 50     130 + 45 = 115 + 65 = 355

130 = 130           45 = 45                115 = 115
