Answer:
Step-by-step explanation:
In order to find the value of ∠EFB here, we have to note our angle relationships.
We know that ∠CFE is already 90°. We also know that ∠CFA is 90°. Angle ∠AFB is inside ∠CFA. Since we know the measure of ∠AFB, we can find the measure of ∠BFC.
Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.
Hope this helped!

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)
Answer:
(0,-13)(1,-10)(2,-7)
Step-by-step explanation:
It has three values for x
Area of a circle = pi* r^2
50.24 = pi* r^2
divide both sides by pi and get...
15.99188868 = r^2
the square root of that is 3.998985957 which rounds to 4
