Answer:
405
Step-by-step explanation:
To find sample size, use the following equation, where n = sample size, za/2 = the critical value, p = probability of success, q = probability of failure, and E = margin of error.
The values that are given are p = 0.84 and E = 0.03.
You can solve for the critical value which is equal to the z-score of (1 - confidence level)/2. Use the calculator function of invNorm to find the z-score. The value will given with a negative sign, but you can ignore that.
(1 - 0.9) = 0.1/2 = 0.05
invNorm(0.05, 0, 1) = 1.645
You can also solve for q which is 1 - p. For this problem q = 1 - 0.84 = 0.16
Plug the values into the equation and solve for n.
Round up to the next number, giving you 405.
Angle D and angle G are the base angles, which means they are equal. If D = 18, then G = 18. Since the sum of the angles of a triangle equals 180 degrees, subtract 18 + 18 from 180 to get angle O.
180 - 36 = 144
Angle O = 144
Hope this helps =)
Your Principal, P, is $400. Your interest rate, expressed as a decimal, is 0.03. Here, n is 1, since there is just 1 compounding period per year.
How much would you have after 16 years under such circumstances?
A = Amount = $400(1+0.03)^16. => $400 (1.03)^16 = $400(1.60)
Thus, you would have accumulated $641.88 after 16 years. Sounds like a pretty good deal to me. ;)
