Answer:

P.E.M.D.A.S, Then combine like terms.

Step-by-step explanation:

(2n +2)(6n + 1)

P.E.M.D.A.S tells you to do parenthasis first, but because both equations are in parenthasis, follow the equation in order. Next, combine like terms.

(2n + 6n)(2+1)

2n + 6n = 8n

2 + 1 = 3

Isolate the variable

8n * 3

8n/ 8 = n

8/ 3 = 2.6

n = 2.6

A random sample of of 100 voters in a town is selected, and 24 are found to support an annexation suit. Find the 96% confidence
lbvjy [14]

Answer: 0.24 +/- 0.088 = (0.152, 0.328)

Step-by-step explanation:

The point estimate p is given by;

p= 24/ 100 = 0.24

Z value for 96% confidence interval is 2.05

The solution for the given confidence interval is derived using the equation

p +/- z√(pq/n)

Where p = 0.24 q= 1-p = 0.76, n=100 z= 2.05

= 0.24 +/- 2.05√(0.24×0.76/100)

= 0.24 +/- 2.05(0.0427)

=0.24 +/- 0.088

= ( 0.152, 0.328)

25% of €40:00 = €<br> And explain it
Wewaii [24]

Answer:

The correct answer is €10.00

Step-by-step explanation:

50% of 40 is 20. 50% of 50 is 25, so what you do is just take 20 and multiply that by 0.5 or you can just take 40 and multiply that by 0.25.

I really hope this helps you out!
