A dot plot gives you a visual display of how data are distributed.
Example: Here are the scores Yolanda received on math quizzes: 6, 10, 9, 9, 10, 8, 7, 7, and 10.
Make a dot plot for Yolanda’s quiz scores.
Step 1: Draw a number line.
Step 2: Write the title below the number line.
Step 3: For each number in the data set, put a dot
above that number on the number line.
Describe the dot plot by identifying the range, the mean, and the median.
Step 4: Identify the range. 10  6  4 Step 5: Find the mean. 76  9  8.4 Step 6: Find the median. 9
Step 7: Find the mode. 10
Greatest value 
Range: least value
Sum of data values Mean: Number of data values

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
