I think it's 25. area is length times width aka...5 X 5 if you take the length times width of the tiles it's 1.
1x = 25 divide both sides by 1...
x ( number of tiles) = 25
Answer:
14
Step-by-step explanation:
PEMDA ( ( ), ^, x, ÷, +, -)
write equation
(2x4) + (12x2) ÷ 4 =?
solve
(2x4) = 8
rewrite
8 + (12x2) ÷ 4
solve
(12x2) =24
rewrite
8 + 24 ÷ 4
solve
24 ÷ 4 = 6
rewrite
8 + 6
Solve
8+6=14
Answer = 14

since it's opened dot and head toward negative infinity.
57 of them were cinnamon.
Explanation:
100-40 = 60 and 3 of those were glazed so that leaves us with 57
To solve for the margin of error:
margin of error = critical value x standard error
To compute for the critical value:
1. compute alpha: α= 1 - (confidence level/100) = 1 - .99 = 0.01
2. Find the critical probability: p = 1 - α/2 = 1 - (0.01/2) = 0.995
3. Look for the z score at the z table, in this case it is 2.58. This is your critical value.
To compute for the standard error, the formula is:
standard error = standard deviation (σ) divided by √n = 1.6 / √420 = 0.0781
Now plug in the following in the formula:
margin of error: 2.58 * 0.0781 = 0.2014 or 0.20
The answer is letter C.
