Answer:
$76.8
Step-by-step explanation:
As, So 20% of 64 will be the markup price.
So 20/100 x 64 = $12.8
Now Markup price = $12.8
And The retail price = markup price + original price = $12.8 + $64 = $76.8
A factor table is like this chart of numbers.
Answer:
y = -1/2x - 2
Step-by-step explanation:
The line is negative, so the slope has to be negative. (-1/2)
You would use the equation to find the first point to plot. -1/2 times 0 is 0. 0-2 equals -2. This means that the first point would be (0,-2). This proves that the correct equation is <u><em>y = -1/2x - 2</em></u>.
Answer:
1.54 m
Step-by-step explanation:
Given information:
<u>Three groups of students</u>
- 20 students with a height of 1.67 m
- 16 students with a height of 1.50 m
- 14 students with a height of 1.40 m
⇒ Total number of students = 20 + 16 + 14 = 50
To find the <u>mean height</u> of all the students, <u>divide</u> the <u>sum of all the students' heights</u> by the <u>total number of students</u>:

Therefore, the mean height of all the students is 1.54 m
Y=(x+1/2)^2-13/4 is the answer to this question.
