To get the probability that randomly selected airfare between Boston and San Francisco will be more than $450, we proceed as follows:
the z-score is given by:
z=(x-μ)/σ
thus the z-score for our information will be:
z=(450-387.20)/68.50
z=0.9168
hence our probability will be:
P(X>x)=1-P(z)
P(z)=0.8212
thus
P(X>x)=1-0.8212=0.1788~17.88%
Answer:
1/3
Step-by-step explanation:
Floral foam, also called oasis, is a cellular
plastic material, available in two types - green
foam and brown/grey foam. Pin-holders also
called kenzan or needle-point holders, is a
series of sharply pointed pins are firmly held in
a solid lead base, to hold thick and heavy
stems securely by impaling them on the pins.
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
