Answer:
1)24
2)15
3)5
4)48
Step-by-step explanation:
Answer:
The last answer is right
Step-by-step explanation:
Because zs cuts the shape in half
If they manage to sell 
tickets, they will earn 
dollars. We want this number to be at least 1000, so the inequality would be
In order to solve this for t, you only need to divide both sides by 15:
So, they need to sell at least 67 tickets to have an income of
dollars
As the level of significance here is 0.05 because we are comparing the p-value with 0.05. Therefore the critical region boundaries here would be given as:
For 5 degrees of freedom, we get: ( from the t-distribution tables )
P(t_5 < 2.571) = 0.975
Therefore due to symmetry, we get:
P(-2.571 < t_5 < 2.571) = 0.95
Therefore the critical region here would be given as: +2.571 and -2.571
First you expand the brackets:
3x - 27 = 30
And then you can solve:
3x - 27 = 30
+ 27
3x = 57
÷ 3
x = 19
Hope this helps!
