Kelly rolls two number cubes 50 times. After each roll, she records whether the number on
each cube is even (E) or odd (O). Her results are shown in the graph. Based on Kelly's results,
which is the most reasonable prediction for the number of times two odd numbers will occur
when two number cubes are rolled 2,000 times?​

Kelly Rolls Two Number Cubes 50 Times. After Each Roll, She Records Whether The Number Oneach Cube Is

Answers

Answer 1

Answer:

480

Step-by-step explanation:

First add the numbers in the table together and put the total as a denominator in a fraction then the amount of times 2 odd numbers appeared as the numerator then put another fraction with 2,000 as the denominator and divide 2,000 by the total then multiply the numerator by that answer to get the correct answer.

Hope this helped!

Answer 2

Using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

What is fraction?

A fraction is " a number is expressed as a quotient  in which numerator is divided by denominator".

According to the question,

Kelly rolls two number cubes 50 times, each cube is even (E) or odd (O).

The graph shows frequency of two numbered cube roll. The frequency of getting EO is 14, frequency of getting OE is 8, frequency of getting EE is 16 , frequency of getting OO is 12.

Total number of frequency = 14 + 8 + 16 + 12

= 50

The fraction of getting two odd numbers when cube is rolled 50 times

= [tex]\frac{12}{50}[/tex].               →(1)

In order to find, when two number cubes are rolled 2,000 times the number of times two odd numbers will occur.

= [tex]\frac{x}{2000}[/tex].            →(2)

Equating two fraction, to get value of 'x'.

[tex]\frac{12}{50} = \frac{x}{2000}[/tex]

[tex]\frac{12*2000}{50}[/tex]  = x

x = 12 × 40

x = 480.

Hence, using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

what is the center?
the circle passes through the point (-7,-7). what is the radius?​

Answers

We have been given image of circle that passes through point [tex](-7,-7)[/tex]. We are asked to find the radius of the circle.

First of all, we will find the center of the circle.

We can see that center of circle is at point [tex](-2,-1)[/tex].

Now we will use equation of circle to find radius.

[tex](x-h)^2+(y-k)^2=r^2[/tex], where, point (h,k) represents center of circle and r represents radius of circle.

Now we will substitute the coordinates of point [tex](-7,-7)[/tex] and coordinates of center [tex](-2,-1)[/tex] and solve for r as:

[tex](-7+2)^2+(-7+1)^2=r^2[/tex]

[tex](-5)^2+(-6)^2=r^2[/tex]

[tex]25+36=r^2[/tex]

[tex]61=r^2[/tex]

Switch sides:

[tex]r^2=61[/tex]

Now we will take positive square root on both sides:

[tex]\sqrt{r^2}=\sqrt{61}[/tex]

[tex]r=\sqrt{61}[/tex]

Therefore, radius of circle will be [tex]\sqrt{61}[/tex] and center is at point [tex](-2,-1)[/tex].

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Eggs = 94

Each box Hold= 6 eggs

So, number of boxes required to hold 94 eggs

= 94 / 6

= 15.66

Hence, smallest number of boxes she needs is 15.67

A Bowling ball is rolled down the alley with the constant velocity of 1.6 m/sec at an angle of 85° to the starting line, the position of the person throwing a bowling ball can be represented by the point (0,0). where is the ball after six seconds?

Answers

We have been given that a Bowling ball is rolled down the alley with the constant velocity of 1.6 m/sec at an angle of 85° to the starting line, the position of the person throwing a bowling ball can be represented by the point (0,0).

We are asked to find the position of ball after 6 seconds.

We will use horizontal position and vertical position formula to solve our given problem.

Horizontal position is given by formula: [tex]x=v\cdot \text{cos}(\theta)\cdot t[/tex] and vertical position is given by formula: [tex]y=v\cdot \text{sin}(\theta)\cdot t[/tex],where,

v = Velocity,

t = Time,

[tex]\theta[/tex] = Angle to the starting line.

For our given problem [tex]v=1.6[/tex], [tex]t=6[/tex] and [tex]\theta=85^{\circ}[/tex].

[tex]x=1.8\cdot \text{cos}(85^{\circ})\cdot 6[/tex]

[tex]x=10.8 \cdot 0.087155742748[/tex]

[tex]x=0.9412820216784\approx 0.94[/tex]

[tex]y=1.8\cdot \text{sin}(85^{\circ})\cdot 6[/tex]

[tex]y=10.8\cdot 0.996194698092[/tex]

[tex]y=10.7589027\approx 10.76[/tex]

Therefore, the position of ball after 6 seconds would be [tex](0.94,10.76)[/tex].

Answer:

(0.8,9.6)

Step-by-step explanation:

x=1.6*cos85* 6=0.8

y=1.6*sin85 *6=9.6

Autumn Friday nights, the time where the unlikely pair of music and sportsmanship collide, and amid it all, drum majors stand tall, leading the mighty Raider Brigade by both conducting and example. I have always dreamed to be in their position, and now, I am thankful to have the chance to make this dream a reality. I view the position of drum major as one of both honor and responsibility, and there are a multitude of reasons I would love to lead in this position for the Raider Brigade. When I was much younger, I used to beg my dad to take me to band concerts, so I could pretend to direct along with the band conductor, and by second grade, I knew that I wanted to play flute. Within this year, I became sure in my dream to become a band director. To me, becoming a drum major would mean that I would get to live my dreams out years in advance, and although my young age may be seen as a disadvantage, it is, in reality, anything but. As an upcoming sophomore, I still vividly remember the transition issues and growing pains that accompany going from middle school to highschool, and because of this, I can give current, relevant advice. Through the 2019-2020 school year I confided in my section leader, who guided me and gave me advice when necessary, and without her, it would have been impossible to make it through the year. If I were to make drum major, I want to form those relationships with upcoming freshmen, to make sure they know they have a place before school begins, in the large, loving Raider Brigade. The Raider Brigade in itself is a beautiful family that has united for the common goals of making music and performing a beautiful show for the crowd, and as a potential drum major, my only aspiration is to make this organization even better. I see true talent in every member, and the only way to build on this is to ignite the passion of showmanship in each individual. This begins with the drum major. All leadership teaches by example, so if the leader is passionate, the band will be passionate. The raider brigade is hard work, but as drum major I intend to make everyone whistle while they work. This will make the beautiful Raider Brigade reach its full, spectacular potential.Overall, I want to be a drum major to accomplish my dreams, make connections with both the freshmen and every other member, and to make this wonderful band reach its full, amazing potential. Finally, I would like to thank you for this opportunity and your consideration, and I wish only the best for this band, which is why I am truly trying out. briefly describe the ending of the book One Of Us Is Lying Recessive sex-linked traits such as color blindness appear more frequently inmales becauseA. males inherit only one sex chromosome.B. males inherit two copies of every sex-linked allele.C. sex-linked alleles are carried only on Y chromosomes.D. males inherit only one sex-linked allele.
