Answer:

2) n< -2 (less than or equal to)

5)x=-6

6) m/2+3=9

4) 6s+48=258

Step-by-step explanation:

2) add 2 to the other side, then divide by -2 to isolate the n, when dividing by a negative number the inequality flips to the other direction

5) subtract 4 to the other side so you get 2/3x=-4, multiply by 3/2 on the right to isolate x, x=(-4)(3)/2, x=-6

6)12/2= 6, 6+3=9

4) the total is 258 so thats on the other side of the equation, she already has 48 so that number isnt going to change with each purchase, however, with each purchase she gets 6 points so for every 6shops + her48 owned already = the 258 she needs to get to

a random sample of 510 high school students has a normal distribution. The sample mean average ACT exam score was 21 with a 3.2
34kurt

Answer:

CI = 21 ± 0.365

Step-by-step explanation:

The confidence interval is:

CI = x ± SE * CV

where x is the sample mean, SE is the standard error, and CV is the critical value (either t score or z score).

Here, x = 21.

The standard error for a sample mean is:

SE = σ / √n

SE = 3.2 / √510

SE = 0.142

The critical value is looked up in a table or found with a calculator.  But first, we must find the alpha level and the critical probability.

α = 1 - 0.99 = 0.01

p* = 1 - (α/2) = 1 - (0.01/2) = 0.995

Using a calculator or a z-score table:

P(x<z) = 0.995

z = 2.576

Therefore:

CI = 21 ± 0.142 × 2.576

CI = 21 ± 0.365

Round as needed.
