How do you find the mean of a stem and leaf plot

1 answer:

6 0

Well, I know to find the mean you add all the numbers and divide it by how many numbers there were, so I'm guessing you just do that with the stem and leaf plot. I hoped this helped a bit

Answer:

3x×2c+1

Step-by-step explanation:

6x+15 =4c-12

$\frac{6x + 15}{4c - 12} = \frac{4c - 12}{4c - 12}$

$\frac{6x + 15}{4c - 12}$

$\frac{3x + 5}{2c - 4}$

$3x + 5 \div 2c - 4$

$3x \times 2c + 5 - 4$

$3x \times 2c + 1$

In the triangle below, suppose that m angle L=(5x-3)m angle M=(4x-7)^ , and m angle N=x Find the degree measure of each angle in

Ludmilka [50]

Because all angles adds up to 180 we are going to add the equations and equal it to 180.

5x - 3 + 4x - 7 + x = 180
5x + 4x + x - 3 - 7 = 180
10x - 10 = 180
10x = 180 + 10
10x / 10 = 190/10
x = 19 degrees

5x - 3
5(19) - 3 = 92 degrees

4x - 7
4(19) - 7 = 69 degrees

angle L = 92 degrees
angle M = 69 degrees
angle N = 19 degrees
