Here, Just substitute their values,
4x + 3y
= 4(3) + 3(6)
= 12 + 18
= 30
In short, Your Answer would be 30
Hope this helps!
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,

Let 
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.

Answer: t^2=-f-576/16
Step-by-step explanation:
Step 1. Switch the equation around:
-16t^2+576=f
Step 2. Subtract 576 from each side:
-16t^2+576-576=f-576
Step 3. Now simplify:
-16t^2=f-576
Step 4. Divide everything now by -16:
-16t^2/-16=f/-16-576/-16
Step 5. Simplify again:
t^2=-f-576/16
Hope I could help! :)
