Answer:
[tex]$\text{P(Choose Cab Once)}=\frac{4}{9} $[/tex]
Step-by-step explanation:
In the morning Elizabeth has three transportation options to work.
It is [tex]$\frac{1}{3} $[/tex] :
In the evening Elizabeth has the same three transportation options to go home.
It is [tex]$\frac{1}{3} $[/tex] again.
But if we consider that she will take the cab once, the options will change to [tex]$\frac{2}{3} $[/tex] because now she can choose 2 options out of 3.
[tex]$\text{P(no cab) }= \frac{2}{3} $[/tex]
In order to use the cab once, we have two options:
She will use the cab in the morning or she will use the cab in the evening:
First route (cab in the morning):
[tex]$\text{Route 1}=\text{P(Choose Cab) } \cdot \text{P(Choose another one)} $[/tex]
[tex]$\frac{1}{3} \cdot \frac{2}{3} $[/tex]
Second route (cab in the evening):
[tex]$\text{Rote 2}=\text{P(Choose another one) } \cdot \text{P(Choose Cab)} $[/tex]
[tex]$\frac{1}{3} \cdot \frac{2}{3} $[/tex]
We have two routes, so
[tex]\text{P(Choose Cab Once)}=\text{Route 1}+\text{Route 2}[/tex]
[tex]$\text{P(Choose Cab Once)}=\frac{1}{3} \cdot \frac{2}{3} +\frac{1}{3} \cdot \frac{2}{3} $[/tex]
[tex]$\text{P(Choose Cab Once)}=\frac{2}{9} \cdot \frac{2}{9} $[/tex]
[tex]$\text{P(Choose Cab Once)}=\frac{4}{9} $[/tex]

Step-by-step explanation:
Square root of 100 = 10
Answer:
10 feet
Step-by-step explanation:
To find the length of a square side using the area, what you need to do is find the square root of the area because a square area is the side length squared soooo.

Simplify each expression. -21v^6/-6v^8
3.5/v^2
Step-by-step explanation:
-21v^6/-6v^8
-21/-6=3.5
v^6-v^8=-2
since -2 cannot be expressed as v^-2 it must be expressed as 1/v^2
so 3.5/v^2 is your answer
Answer:
7/2v^2
Step-by-step explanation:
7/2v^2 is the answer to the problem.
If we are given x such that 25^x-9^y=18 and 5^x-3^y=3, compute 5^x+3^y.
25 = 5*5 and 9 = 3*3, which we can exploit to write
[tex]25^x-9^y=(5^2)^x-(3^2)^y=5^{2x}-3^{2y}=(5^x)^2-(3^y)^2[/tex]
so that this expression is actually a difference of squares. We can factorize this to get
[tex](5^x-3^y)(5^x+3^y)=18[/tex]
and given that [tex]5^x-3^y=3[/tex], we divide both sides by this to get
[tex]5^x+3^y=\dfrac{18}3=\boxed{6}[/tex]

5 units
Step-by-step explanation:
I used the pythagorean theorem (a^2 + b^2 = c^2) to find the answer. I put 3 in a and 4 in b. I squared them and got 9 + 16 = 25. I found the square root of 25 which is 5 and that is my answer.
Mike makes a commission of 10% on each TV set sold at store. Each TV costs $120. How much
money will he make as commission if store sells 25 TV sets?
Answer:
$300
Step-by-step explanation:
10% = .1 and each TV costs 120 so .1*120=12 then you take 12*25 since 12 is the money he makes for seeling the tv multiplied by the total TV's sold and you get 300 so Mike makes $300
Answer:
300 just cross multiply to get the answer.

20. In the figures below, the cube-shaped box is 6 inches wide and the rectangular box is 10 inches long, 4 inches wide, and 4 inches high. How much
of the cube-shaped box than the rectangular box?
A. 50 cubic inches
B. 60 cubic inches
C. 66 cubic inches
D. 56 cubic inches
Answer:
56 cubic inches
Step-by-step explanation:
Volume of cube box = 6^3 = 6 *6*6 = 216 , Volume of rectangular box = 10*4*4 = 160 . Difference = 216 - 160 = 56 cubic inches. 56 cubic inches greater is the volume of the cube-shaped box than the rectangular box.
Answer:
Step-by-step explanation:
cube volume=side^3
given that the side is 6, the volume is 6^3 or 216 cubic inches
volume regular rectangular prism=length times width times height
given that length=10, width is 4 and height is 4, volume=10*4*4=160 cubic inches
how much greater
216-160=56
it is 56 cubic inches greater
this is ur answer buddy]
Write the equation of a line that passes through (4,-10) and has a slope of 2, please!
Answer:
y = 2x - 18
Step-by-step explanation:
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (4, -10) and Gradient (m): 2
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - (-10) = 2(x-4)
This becomes:
y + 10 = 2x - 8
Keep solving by moving the 10 over to the other side:
y = 2x -8-10
y = 2x - 18
An easy way to double check:
1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.
2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.
Hope this helped : )

The correct option is (B).
What is mean by Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Now, From 0-4 the graph is uniformly increasing which represents 3 hours that's it's moving.
Then from 2-3 there no increment or decrement which represents it is in rest.
Then, from 4 - 5 the graph is uniformly increasing again which represents 1 more hours it is moving.
Hence, We get;
⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.
