Step 1: Simplify both sides of the equation.
−(5−(a+1))=9−(5−(2a−3))
−(5−(a+1))=9+−1(5−(2a−3))(Distribute the Negative Sign)−(5−(a+1))=9+(−1)(5)+−1(−2a)+(−1)(3)−(5−(a+1))=9+−5+2a+−3a+−4=9+−5+2a+−3(Distribute)a−4=(2a)+(9+−5+−3)(Combine Like Terms)a−4=2a+1a−4=2a+1Step 2: Subtract 2a from both sides.a−4−2a=2a+1−2a−a−4=1Step 3: Add 4 to both sides.−a−4+4=1+4−a=5Step 4: Divide both sides by -1.−a−1=5−1a=−5

Answer:

a)-5

Step-by-step explanation:

-(5-(a+1))=9-(5-(2a-3))

= -(5-a-1)= 9-(5-2a+3)

= -5+a+1 = 9-5+2a-3

= -4+a = 1+2a

= -4 - 1 = 2a-a

= -5 = a

A sociologist develops a test to measure attitudes towards public transportation, and 27 randomly selected subjects are given th

taurus [48]

Answer:

The margin of error for the 95% confidence interval for the mean score of all such subjects is of 8.45.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 27 - 1 = 26

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 26 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.95}{2} = 0.975$ . So we have T = 2.0518
