a) The probability is $\frac{65}{357}$.
b) The probability is $\frac{781}{1000}$.
c) The probability is $\frac{58}{195}$.
d) The probability is $\frac{65}{357}$.
e) We can construct a probability tree for these probabilities. Below is the probability tree:probability tree for airlines. Therefore, the above figure is the probability tree for airlines.
The probability that a randomly selected flight was Delta and was late is $\frac{65}{357}$.Therefore, the probability is $\frac{65}{357}$.
The probability that a randomly selected flight was United or was on-time is $\frac{781}{1000}$.Therefore, the probability is $\frac{781}{1000}$.
Given the flight was late, the probability that it was from American is $\frac{58}{195}$.Therefore, the probability is $\frac{58}{195}$.
Given the flight was from Delta, the probability that it was late is $\frac{65}{357}$.Therefore, the probability is $\frac{65}{357}$.
We can construct a probability tree for these probabilities. Below is the probability tree:probability tree for airlines. Therefore, the above figure is the probability tree for airlines.

Answer:
The percentage saved is 1.5% .
Step-by-step explanation:
As given
You plan to buy $12,000 in computers at a local chain store. There are two stores located about the same distance from your office but in different cities with different tax rates.
One city has a tax rate of 7% and the other has a tax rate of 8.5%.
As
7% is written in the decimal form .
= 0.07
Tax price at 7% tax rate = 0.07 × Cost of the computer
= 0.07 × 12000
= $ 840
8.5% is written in the decimal form .
= 0.085
Tax price with 8.5% tax rate = 0.085 × Cost of the computer
= 0.085 × 12000
= 1020
Change in the tax rate = Tax price with 8.5% tax rate - Tax price at 7% tax rate.
= 1020 - 840
= $180
Percentage saved = 1.5%
Therefore the percentage saved is 1.5% .
Answer:
60
Step-by-step explanation:
Answer: 63
Step-by-step explanation:
PEMDAS, so parentheses come first,
9+9=18
And the next in your problem would be Addition.
So,
18+45=63
Which expression can be used to determine the greatest possible volume of the cardboard box?
A) (x−7)(x−11)x
B) (7−2x)(11−2x)x
C) (11−7x)(11x−7)
D) (7x−11)(7−11x)
Answer:
Option B
Step-by-step explanation:
Given is a rectangle with width 7 and length 11.
From each corner of the rectangle a square of length x is cut and foled to make a box
Now for the open box we made, height = x
width = rectangle width - 2 times d
= 11-2x
Length = rectangle length-2x
Hence volume of box
=lwh
= (7-2x)(11-2x)x
Answer: B)
Step-by-step explanation:
Given: The length of the cardboard = 11 in.
The width of the cardboard =7 in.
If a box is created without a top from a piece of cardboard, but cutting out square corners with side length x, then the dimensions of box will be:-
Width (w)=
length (l)=
Height (h)=
Now, volume of rectangular box is given by :-
Hence, the expression can be used to determine the greatest possible volume of the cardboard box is given by :-
