Answer:
x = 5
Step-by-step explanation:
Maybe you have ...
n(x) = 2x +7
and you want x for n(x) = 17.
17 = 2x +7
10 = 2x . . . . . . subtract 7
5 = x . . . . . . . . divide by 2
the value of x for the right triangle is 60
Step-by-step explanation:
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](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7BX-%5Cmu%7D%7Bs%7D%3D%5Cdfrac%7B179-170%7D%7B3.75%7D%5C%5C%5C%5Cz%3D2.4)
Let ![z_{crict}=1.64](https://tex.z-dn.net/?f=z_%7Bcrict%7D%3D1.64)
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.
