Find a quadratic equation whose roots are -3 and 5
Answers
Answer:
x² - 2x - 15 = 0Step-by-step explanation:
Roots:
x₁ = -3, x₂ = 5The equation:
(x - x₁)(x - x₂) = 0(x - (-3))(x - 5) = 0(x + 3)(x - 5) = 0x² + 3x - 5x - 15 = 0x² - 2x - 15 = 0Step-by-step explanation:
Let the roots be a and b
a=-3b=5To form a equation the formula is
[tex]\sf x^2-(a+b)x+ab[/tex]
[tex] \sf➡ {x}^{2} - ( - 3 + 5)x + ( - 3)5 \\ \sf \: ➡ {x}^{2} - 2x - 15 = 0[/tex]

En una muestra de 50 restaurantes de comida rápida, la venta media fue de $3.000, y la desviación estándar, $200. El intervalo de confianza del 95% es
Answers
Respuesta:
(2945.411; 3054.589)
Explicación paso a paso:
Dado ;
Tamaño de la muestra, n = 50
Media, xbar = 3000
Desviación estándar, s = 200
Nivel de confianza, Zcrítico al 95% = 1,96
El intervalo de confianza se define como:
Xbar ± margen de error
Margen de error = Zcrítico * s / sqrt (n)
Margen de error = 1,96 * 200 / sqrt (50)
Margen de error = 54.589
Límite inferior = (3000 - 54.589) = 2945.411
Límite superior = (3000 + 54.589) = 3054.589
(2945.411; 3054.589)

As an estimation we are told 5 miles is 8 km.
Convert 55 miles to km
Answers
Answer:
88 km.
Step-by-step explanation:
If 5 miles is 8 km,
55 miles is 88 km.
What you need to do is 55/5 = 11.
Then multiply that 11 to 8.
11 * 8 = 88.
Basically, if you are multiplying 5 by 11 to get 55, you need to multiply 8 by 11 to get 88.

The area of a right triangle is 3gh. Find the height if the base is 3gh.
Area of a triangle: A = 1/2bh
Answers
Answer: height is 2
Step-by-step explanation:
A = 1/2bh
A = 3; b (base) = 3. Substitute these values in the formula and solve.
3 = 1/2*3*h = 3/2 h
h = 3 * (2/3) = 2
Answer:
Height = 2
Step-by-Step Explanation:
So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.
Area = 3gh
Base = 3gh
Height = ?
Plug & Chug
3gh = 1/2 (3gh)(h)
2/1 · 3gh = 1/2 (3gh)(h) · 2/1
[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]
h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]
h = 2
