Answer:One week gas was $1.25 per gallon. The next week gas was $1.50 per gallon. By 20 percentage the price increase.
Step-by-step explanation:
In your problem:
p = 18.3% = 0.183
n = 130
The standard error can be calculated by the formula:
SE = √[p · (1 - p) / n]
= √[0.183 · (1 - 0.183) / 130]
= 0.0339
The standard error of the proportion is 0.034.
In this problem
You have a triangle with 3 sides labeled A, R, O and 3 vertices labeled J, K, E.
To name a triangle, what you do is simply list all of its vertices.
The order doesn't matter.
So
let's take a look at all the possible choices.
A. EJR - Nope.E and J are OK. But R is the line segment.
B. KE - Nope. K and E is OK, but Only has 2 of the vertices.
C. JE - Nope. J and E is OK, but Only has 2 of the vertices.
D. KEJ - Yes. All three vertices have been named. This is an acceptable name for the triangle.
E. JAOE - Nope. Only has 2 of the vertices and A and O are line segments
F. JKE - Yes. All three vertices have been named. This is an acceptable name for the triangle.
therefore
the answer is
KEJ and JKE
That would be 3 to the nth power—>3^n
