Answer:
"0.9739" is the correct answer.
Step-by-step explanation:
The given values are:
The ratio of true to false effects,
= 0.07
The power of study,
= 0.8
Alpha level,
= 0.05
Now,
The percentage of effects proved as significant will be:
= 
= 
0r,
= 
%
The percentage of false effects will be:
= 
= 
or,
= 
%
The total effects will be:
= 
= 
%
hence,
The probability that this effect is real will be:
= 
= 
Answer: 15x-14y=22
3x+5y=7
2.5x-y=17
42x+0.4y=15
Step-by-step explanation:
The standard linear equation of two variables x and y is given by :-
Ax +By = C , where A is a positive integers, and B, and C are integers.
Therefore, from the given options the linear equations that are in standard form are
15x-14y=22
3x+5y=7
2.5x-y=17
42x+0.4y=15
[-2x+8y=14 is not in standard form ∵ -2 is a negative integer.]
Let n = 30
We are actually looking for a_30.
a_30 = 4(30) + 1
a_30 = 120 + 1
a_30 = 121
