Answers

Answer 1

Therefore , the solution of the given problem of percentage comes out to be  athletes who took move  285 to finish the race is 64%.

Define percentage.

A percentage is what is used to describe a fraction of a whole when it is stated as a number range between 0 and 100. 100% of something, 50% of something, and 0% of something are all equal. After dividing the portion of the whole by the entire, multiply the result by 100 to arrive at a percentage.

Here,

For the table to get the total frequency is:

=> 3+6+9+7

=>9+9+7

=>25

The frequency greater than 285 is

9+7 = 16

So,

the percentage of the athletes who took move  285 to finish the race is:

=> 16/25 * 100

=> 0.64 * 100

=> 64%

Therefore , the solution of the given problem of percentage comes out to be  athletes who took move  285 to finish the race is 64%.

Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (10 points)

Answers

9514 1404 393

Answer:

(1, 4)(2, 8)(3, 12)

Step-by-step explanation:

The ratios all have ...

  first number : second number = 1 : 4

Using first numbers of 1, 2, 3, the second numbers can be found by multiplying these by 4. (1, 4), (2, 8), (3, 12)

__

You plot these (x, y) points the same way you plot any point on a coordinate grid. The first (x) value is the horizontal distance from the vertical axis. Positive is to the right. The second (y) value is the vertical distance from the horizontal axis. Positive is up.

__

Of course, the origin is where the horizontal and vertical axes meet. It can be convenient to find one of the coordinates on its respective axis, then use the other coordinate to find the point at the desired distance from that axis.

Usually, you would choose the axis on the basis of how easy it is to determine exactly where the coordinate lies. If the y-axis is marked every 5, for example, it might be hard to determine where a multiple of 4 will lie. Locating the x-coordinate on the x-axis may be an easier way to start.

Suppose ABCD is a parallelogram. Find the value of x and y.

Answers

answer:

x = 4

y = 19

step-by-step explanation:

we know that this is a parallelogram, so opposite sides are equalthis is one of the properties of a parallelogram

therefore,

segment AB = segment DC and segment AD = segment BC

now plug in the expressions according to what we know (& solve)

AB = DC

5x - 13 = 9x - 29

-13 = 4x - 29

16 = 4x

x = 4

AD = BC

Since LM = 9 and ST = 6 and those are corresponding sides, the ratio of any side from [tex]\triangle{PLM}[/tex] and its corresponding side from [tex]\triangle{UST}[/tex] is 9 to 6 which can be expressed as the fraction 9/6 or 3/2.

LQ and SR are corresponding segments, so set up two ratios.

[tex]\frac{LQ}{SR}=\frac{3}{2}\\\\\frac{x-1}{x-2}=\frac{3}2}[/tex]

How to obtain the equation for the line of fit?

The equation for the line of fit is obtained inserting the points of the data-set into a linear regression calculator.

Given:

From the scatter plot, the points are given as follows:

(1, 5.4), (2, 5), (3, 4.6), (4, 4.9), (5, 4.1), (6, 3.9), (7, 3.6), (8, 3.3).

Inserting these points into the linear regression calculator, we get

y = -0.29x + 5.67.

Now, for x= 10 year

y = -0.29(10) + 5.67 = 2.77 minutes.

which is closest to 2.83 minutes.

If you could take one sample from the mystery bag in order to make a prediction, would you rather draw a sample of 10 marbles or a sample of 20 marbles. Explain your choice by referring to the representations of the two distributions.

Answers

I would choose to draw a sample of 20 marbles in order to make a more accurate prediction.

How to illustrate the sample?

In general, it is generally better to draw a larger sample if you are trying to make a prediction. This is because a larger sample will provide more information and will therefore lead to a more accurate prediction.

For example, imagine that you are trying to predict the proportion of red marbles in a bag based on the samples that you draw. If you draw a sample of 10 marbles, there is a good chance that the proportion of red marbles in your sample will be different from the true proportion of red marbles in the bag.

However, if you draw a sample of 20 marbles, the proportion of red marbles in your sample will be more likely to be closer to the true proportion of red marbles in the bag.

A bag drawing contains 2 red balls and18 green a ball is chosen at random from the bag

Answers

Probability of drawing a red ball:

Total number of balls = 2 + 18 = 20

number of red balls = 2

number of green balls = 18

total number of favourble outcomes = 2

probability = number of favourable outcomes/number of total outcomes.

= 2/20 = 1/10

Therefore probability of drawing a red ball is 1/10.

Probability of drawing a green ball:

total number of balls = 2 + 18 = 20

number of green balls = 18

number of red balls = 2

total number of favorable outcomes = 18

probability = number of favourable outcomes/number of total outcomes.

= 18/20 = 9/10

Therefore probability of drawing a green ball is 9/10.
