Answer: 0.02055867
Step-by-step explanation:
Given :
, since the alternative hypothesis is two-tailed , so the test is a two tailed test.
Sample size : n= 30
Degree of freedom for t-distribution = 
Test statistic= t= -2.43
By using the normal t-distribution table ( or calculator ) , we have
The corresponding P-value for two tailed test = 0.02055867
Answer:
Step-by-step explanation:
u have a difference of squares
25x^2 - 16 = 0
(5x - 4)(5x + 4) = 0
5x - 4 = 0 5x + 4 = 0
5x = 4 5x = -4
x = 4/5 x = -4/5
so x = 4/5 or x = -4/5
Answer:
x = - 4/3
Step-by-step explanation:
3(x + 4) - 1 = 7
3x + 12 - 1 = 7
3x + 12 = 8
3x = -4
x = -4/3

Answer:
It is possible to devise a tactic to always win the game.
Step-by-step explanation:

As long as you get to place your first underpad on the edge of the table you will gain the advantage. After the edges if the round table have been used up, you begin the process against the ones before. Here is a rough sketch to help you out. Hope i helped!!!
