Let's form the difference of the two expressions and see what we can learn.
(2y -x) -(2x -y) = 2y -x -2x +y = 3y -3x = 3(y -x)
Since y > x, this is positive, so 2y -x is greater than 2x -y.
Answer:
Step-by-step explanation:
It is given that a radio show last for h hours for every 60 minutes of air time during the show there are 8 minutes of commercials.
The expression represents the air time in minutes available for talk and music .
Since bothe the terms in the given expression are like terms as they have same variable h.
So by combining like terms, we get the fllowing expression:
[Since 60-8=52]

Answer:
allows us to accept the null hypothesis
Explanation:
The z test(in a normal distribution) score for the critical region determines whether we reject the null hypothesis(H0) or accept the null hypothesis(reject or fail to reject the null hypothesis). If we fail to reject the null hypothesis, then we have accepted the alternative hypothesis (H1). The critical region rejection for z test is calculated using alpha and z score, if z score is greater or less than alpha(positive or negative), we reject the null hypothesis.
