If a line plot represents 12 pieces of data, how many dots does it have?
zhuklara [117]

Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.

Step-by-step explanation:

A line plot is a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data.

The main difference between a line plot and a line graph is that the line plot shows the frequency of number within a set, and the line graph shows the value of one variable relative to another.The number of dots  in a line plot will be equal to the number of data points.

Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.

X + y = 152,<br><br> 8.5x + 12y = 1,656<br><br> How many hats were sold?
Elodia [21]

Answer:

x = 48 and y = 104

Step-by-step explanation:

Given equations are:

x+y = 152\\8.5x+12y=1656

From equation 1:

x = 152-y

Putting the value of y in equation 2

8.5(152-y)+12y = 1656\\1292-8.5y+12y = 1656\\3.5y+1292 = 1656\\3.5y = 1656-1292\\3.5y = 364\\\frac{3.5y}{3.5} = \frac{364}{3.5}\\y = 104

Now we have to put the value of y in one of the equation to find the value of x

Putting y = 104 in the first equation

x+y = 152\\x+ 104 = 152\\x = 152-104\\x = 48

Hence,

The solution of the system of equations is x = 48 and y = 104

The value of variable which was assumed for number of hats, is the total number of hats.

Please help..<br><br> *Those who answer random for points will be reported*
ch4aika [34]
I believe its asking to find X, Im sorry if Im wrong and its something else, the question confuses me.

1) x = 16

2) x = 16

3) x = 16

X always equals 16

____________________________
EXPLANATION

x/2 - 5 = 3

16/2 - 5 = 3

8 - 5 = 3

3= 3

x/2 = 8

16/2 = 8

8 = 8

x = 16

16 = 16

Marking me brainliest would be much appreciated! Im trying to get on the leaderboard
