Answer:
190
Step-by-step explanation:
Data provided in the question:
Confidence level = 99%
Therefore,
α = 1% = 0.01
[ from standard normal table ]
z-value for 
= 2.58
Margin of error, E = $0.06
Standard deviation, σ = $0.32
Now,
n = 
Here,
n is the sample size (or the minimum number of gas stations )
on substituting the respective values, we get
=
= 
= 13.76²
= 189.3376 ≈ 190
Hence,
minimum number of gas stations that she should include in her sample is 190
The Kangaroo Rat and the common tree shrew is familiar because the kangaroo rat and the tree shrew have the same class: Mammalia, same phylum: Chordata, and the same kingdom : Animalia. They both are identical because they are small look like small rats etc.
<span>x/8+12 = 16 // - 16
x/8-16+12 = 0
1/8*x-4 = 0 // + 4
1/8*x = 4 // : 1/8
x = 4/1/8
x = 32
x = 32

Answer:
D. ∠1 ≅ ∠3
Step-by-step explanation:
In order to show the lines parallel, you must show how one of the angles 1 or 4 relates to one of the angles 2 or 3. Possibilities include ...
∠1 +∠2 = ∠3 +∠4 = 180°
∠1 = ∠3
∠2 = ∠4
The second of the possibilities listed here matches choice D.
