Graphs have several purposes, including showing and comparing data and illustrating facts. Seven main types of graphs exist: the bar or Pareto graph, the pie chart or circle graph, the histogram, stem and leaf plots, dot plots, scatter plots, and time-series graphs. Bar or Pareto graphs show a bar for each category or set of data that is qualitative. Pie graphs show data in the form of a pie, and each piece of the pie represents a different data set. Histograms look similar to bar graphs, Histograms look similar to bar graphs,and they illustrate quantitative and not qualitative data. Stem and leaf plots illustrate quantitative data and emphasize the high point in the data. Dot plots are combination of histograms and stem-and-leaf plots. Scatter plots use correlation and regression to show trends. Time-series graphs display data at different points in time.

This type or graph is used to show comparisons between values, with a bar representing each separate value. Categories or groups are commonly plotted on the horizontal axis (axis X) and a quantitative or numerical scale is plotted on the vertical axis (axis Y). Bar graphs are used to plot both continuous and discontinuous, or discrete, data.

advantages: show each data category in a frequency distribution, display relative numbers/proportions of multiple categories, summarize a large amount of data in a visual, easily intepretable form, make trends easier to highlight than tables do, estimates can be made quickly and accurately, permit visual guidance on accuracy and reasonableness of calculations, accessible to a wide audience

disadvantages: often require additional explanation, fail to expose key assumptions, causes, impacts and patterns, can be easily manipulated to give false impressions

Find the value of x, y, and z in the rhombus below.

Yuki888 [10]

Solution:

It should be noted:

Opposite sides of a rhombus are always equal.
Opposite angles of a rhombus are always equal.

Thus:

(-y - 10) = 90°
3z - 3 = 90°
4x - 2 = 90°

Finding x:

4x - 2 = 90°
=> 4x = 90 + 2
=> 4x = 92
=> x = 23

Finding y:

(-y - 10) = 90°
=> -y - 10 = 90°
=> -y = 100
=> y = -100

Finding z:

3z - 3 = 90°
=> 3z = 90 + 3
=> 3z = 93
=> z = 31

The two lines y= 6x+15 and y= mx+4 intersect at x= -2. What is the y-coordinate of their intersection point

taurus [48]

Answer:

The y-coordinate of their intersection point is 3

That is y=3

Step-by-step explanation:

Given two lines are y=6x+15 and y=mx+4

Given that the two lines intersect at x=-2

To find the y coordinate of their intersection point :

Equating the two lines

6x+15=mx+4

6x+15-mx-4=0

6x-mx+11=0

(6-m)x+11=0

At x=-2 (6-m)x+11=0

(6-m)(-2)+11=0

(6-m)(-2)=-11

$6-m=\frac{11}{2}$

$-m=\frac{11}{2}-6$

$-m=\frac{11-12}{2}$

$-m=\frac{-1}{2}$

$m=\frac{1}{2}$

Substitute the value $m=\frac{1}{2}$ in y=mx+4 we get

$y=\frac{1}{2}x+4$

At x=-2 $y=\frac{1}{2}(-2)+4$

$=-1+4$

$=3$

Therefore y=3

Therefore the y-coordinate of their intersection point is 3

I went to the grocery store with $50. I purchased two gallons of milk for $3 each, a loaf of bread for $2, and three dozen of eg

Fofino [41]

Answer:

The answer to your question is $36

Step-by-step explanation:

Data

Total money = $50

2 gallons of milk = $3

a loaf of bread = $2

a dozen of eggs = $3

Write an equation to solve this problem

Cost of 2 gallons of milk + a loaf of bread + 3 dozens of eggs + remainder = total cost

Substitution

$3 + $2 + 3($3) + remainder = $50

Simplification

3 + 2 + 9 + remainder = 50

remainder = 50 - 3 - 2 - 9

result

remainder = $36

At track practice, Coach Wilson told the team to split into groups of four for a special relay. The first runner had to run 1 la

amid [387]

You can multiply the number of laps each person ran by the yards in each lap and then add them together:

440 + 2(440) + 3(440) + 4(440)
= 440 + 880 + 1,320 + 1,760
= 4,440 yards

Or you can add the laps first, then multiply by the yards in each lap
(1 + 2 + 3 + 4)(440)
= 10 x 440
= 4,400 yards
