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.
Let me see a better picture
Answer:
9 3/4 inches
Step-by-step explanation:
If we are finding how much taller Sara is, we need to subtract
6 ft 3 3/4 - 5 ft 6in
I like to line up vertically
6 ft 3 3/4
- 5 ft 6in
----------------
We need to borrow 1 ft and make it 12 inches
5 ft 3+12 3/4
- 5 ft 6in
----------------
5 ft 15 3/4
- 5 ft 6in
----------------
0 9 3/4 inches
My answer I got 9x13and half over 1=x
Answer:
See below.
Step-by-step explanation:
This is conveniently done using a 24-hour representation of the given time:
... 2:30 pm = 14:30
Honolulu = 14:30 -10 = 4:30 . . . . 4:30 am
London = 14:30 - 0 = 14:30 . . . . 2:30 pm
Los Angeles = 14:30 -8 = 6:30 . . . . 6:30 am
Paris = 14:30 +1 = 15:30 . . . . 3:30 pm
Tokyo = 14:30 +9 = 23:30 . . . . 11:30 pm
Washington = 14:30 -5 = 9:30 . . . . 9:30 am
