Data
E ( 9 , 7 )
F ( - 1, 5)
Formula
![Xm = \frac{x1 + x2}{2}](https://tex.z-dn.net/?f=Xm%20%3D%20%5Cfrac%7Bx1%20%2B%20x2%7D%7B2%7D)
![Ym = \frac{y1 + y2}{2}](https://tex.z-dn.net/?f=Ym%20%3D%20%5Cfrac%7By1%20%2B%20y2%7D%7B2%7D)
Substitution and simplification
![Xm = \frac{9 -1}{2}](https://tex.z-dn.net/?f=Xm%20%3D%20%5Cfrac%7B9%20-1%7D%7B2%7D)
![Xm = \frac{8}{2}](https://tex.z-dn.net/?f=Xm%20%3D%20%5Cfrac%7B8%7D%7B2%7D)
Xm = 4
![Ym = \frac{7 + 5}{2}](https://tex.z-dn.net/?f=Ym%20%3D%20%5Cfrac%7B7%20%2B%205%7D%7B2%7D)
![Ym = \frac{12}{2}](https://tex.z-dn.net/?f=Ym%20%3D%20%5Cfrac%7B12%7D%7B2%7D)
Ym = 6
Result
(4 , 6)
Answer:
x = 2√2
Step-by-step explanation:
This is a 45-45-90 triangle. This means that if the legs are x, then the hypotenuse is x√2.
In the case, the hypotenuse is already 4. So we have the equation:
x√2 = 4
Multiply both sides by √2
2x = 4√2
Divide both sides by 2
x = 2√2
To answer the problem just add the frequencies that
correspond to email counts that are 19 or fewer. So you're adding the counts
that correspond to 0-9 and 10-19. So the frequency of 0-9 is 4 and the
frequency of 10 -19 is 7. So 4 + 7 = 11
Answer: The length of the base of the triangle is 16 inches.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula
Area of a triangle (A) = base x height x 1/2
Replacing with the values given:
42 = b (5 1/4) 1/2
Solving for b (lenght of the base)
42 / (5 1/4) 1/2 = b
16 in = b
The length of the base of the triangle is 16 inches.

Answer: -2x + 5x^2
Step-by-step explanation:
3x + 6x^2 - 5x - x^2 = x(3-5) + x^2(6-1) = -2x + 5x^2
