How can data be represented by a scatter plot?

1 answer:

7 0

Scatter plots are used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another. Each row in the data table is represented by a marker whose position depends on its values in the columns set on the X and Y axes.

A line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5. What is the value of n?

Lady_Fox [76]

The slope of y = 2x - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points A and B is also 2. This means

(8 - 4) / (6 - n) = 2

Solve for n :

4 / (6 - n) = 2

4/2 = 6 - n

2 = 6 - n

n = 6 - 2

n = 4

The population of a town is 20,000 and is decreasing at a rate of 5% per year. What is the population after 23 years?

AVprozaik [17]

I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.

Some bikes and trikes are on the playground. There are 7 seats and 19 wheels. How many bikes are there? How many trikes are ther

snow_tiger [21]

Okay here we go!
1. I'm a visual person so i would start by drawing circles for the wheels.
o o o o o o o o o o o o o o o o o o o
2. I tried separating them by threes
ooo ooo ooo ooo ooo ooo o
2 By two's
oo oo oo oo oo oo oo oo oo o
3. then i started to count
ooo ooo ooo ooo ooo = 15 and i still had 4 left over
oo oo = 4 and that would equal to 19 wheels!

the answer is: there are 5 trikes and 2 bicycles!!!!!

A map of a park says its scale is 1 to 100. What does that mean?

Alex777 [14]

A scale is a term that refers to the representative fraction for comparing the original length and image length of a given object. It means implies that every 1 unit on the drawing is equal to 100 units on the park.

A scale is a term that can be referred to as the representative fraction that compares the original length and image length of a given object. Types of scale include enlarged scale, reduced scale, and real scale.

Enlarged scale is a scale that is used when the size of a given object is to be increased.
Reduced scale is used when the size of a given object is to be decreased.
Real scale implies the exact size of a given object.

Scale can be expressed as;

Scale = $\frac{length on drawing}{original length}$

Thus a scale has no unit.

Therefore, the given question implies that every 1 unit on the drawing is equal to 100 units on the original park. Thus it is a reduced scale.

Please help me with these 2 question.

Answer:

Step-by-step explanation:

- sqrt(39) and square root 47

are the limits. The - square root of 39 is smaller than - 6. So the integer to use here is - 6

sqrt (47) = 6.686. Here the square root is larger than the closest integer.

The integer to use is 6

- 6 + 6 = 0
