Since you always round up when you estimate in the middle lets say theres 420 tickets. Each is 7.95, but we'll round it to 8.00. 420x8.=3,360. After that part we need to find about how much tickets were refunded. So we round 18 to 20 and each ticket is still 8$. 20x8=160. Finally in all, we do 3,360-160=3200. Its an overestimate because we rounded up. Im not sure what else youre asking but thats the basic answer.
Answer:
1st answer
Step-by-step explanation:
To find this, multiply 90 by 100 to get 9000. Then divide by 100 to get 9.
9 thousands can go into 90 hundreds.
Hope this helped!
I dont get what you are asking me
Answer: option A
Step-by-step explanation: We can only make a conclusion regarding this question by picking a level of significance.
Hence I will assume a 5% level of significance, that's α = 0.05.
If p > α, it simply means that we have a high chance of committing a type 1 error (because α is the probability of committing a type 1 error), hence we reject the null hypothesis meaning it is wrong.
If p < α, it means that we have a very low chance of committing a type 1 error hence we accept the null hypothesis because it is right.
Note even if we decide to try any reasonable value of α, we will come to the same conclusion made above.
