5 0

Answer:

Answer is - 2.

Step-by-step explanation:

(f+g) (x)=f(x) +g(x)=x^2 -2x +6x+4

=x^2 +4x+4=0

If x=-4, then (f+g) (-4) =16-16+4=4

if x=-2, then (f+g) (-2)=4-8+4=0

Dmitriy789 [7]

Answer: Yes, This sample provide evidence that the length of time for baseball games is more than 170 minutes.

Step-by-step explanation:

Since we have given that

Mean length of the games = 179.83

Standard error = 3.75

We need to find the value of P(X>170).

So, it becomes,

z=\dfrac{X-\mu}{s}=\dfrac{179-170}{3.75}\\\\z=2.4

Let z_{crict}=1.64

Since z is greater than z(critical value).

So,Yes, This sample provide evidence that the length of time for baseball games is more than 170 minutes.
