There are 3 cubes in a bag. Two are red and one is green. Sammy randomly selected a cube, put it back and selected another cube. What is the probability of getting to reds?
Answer: 2/3
Step-by-step explanation:
Number of red cubes = 2
Number of green cubes = 1
Total cubes in the bag = 3
The question relates to a probability with replacement. The probability of getting two reds will be the probability of picking red the first time multiplied by the probability of picking red the second time. This will be:
= 2/3 × 2/3

(6n^3 - 57n^2 + 69n - 14) ÷ (n - 1/2)
Answer:
[tex]Lets\ consider\ the\ divisor\ (n-\frac{1}{2})\ as\ g(x) \\In\ order\ to\ perform\ synthetic\ division\ we\ need\ to\ find\ the\ zero\ of\ the\ divisor\ . \\Hence,\\g(x)=0\\n-\frac{1}{2}=0\\n= \frac{1}{2}\\[/tex]
[tex]Now\ we\ must\ write\ the\ dividend\ in\ its\ standard\ form\ and\ seperate\ out\ its\ coeffeicient.[/tex][tex]So,\\\\The\ Coefficients\ will\ be\ in\ this\ order\ : 6,-57,+19,-14[/tex]
[tex]\frac{1}{2}[/tex] | 6 -57 19 -14
+ | 3 -27 -4
Q = [6 -54 -8] |-18 =R
[tex]Hence,\\The\ acquired\ quotient\ is\ 6n^2-54n-8[/tex]
Hence,
As the divisor is rational,
The quotient would be multiplied by the zero(1/2).
[tex]Hence,\\the\ final\ quotient\ = 3n^2-27n-4[/tex]

A box is sitting on the floor. The box was then pulled with a force, Ft. The box did not move. The free-body diagram of the box is shown.
Which describes the motion of the box based on the resulting free-body diagram?
A. It is moving up with a net force of 20 N.
B. It is moving to the right with a net force of 10 N.
C. It is in dynamic equilibrium with a net force of 0 N.
D. It is in static equilibrium with a net force of 0 N.
Answer:
It is in static equilibrium
Explanation:
edge 2021
The box is in static equilibrium, with a net force of 0 N.
Option D is the correct answer.
What is static equilibrium?Static equilibrium refers to a state of balance where an object is at rest and has no acceleration.
In other words, the object is not moving and is not being subjected to any external forces that would cause it to move.
We have,
The box is at rest and is not moving.
This means that the net force acting on the box is zero.
From the free-body diagram,
We know that there is a force, Ft, acting on the box, and there is an equal and opposite force, Fg, due to gravity.
Since the box is not moving, the force of friction, Ff, must also be present to balance the force of the pull.
So,
The box is in static equilibrium, with a net force of 0 N.
Thus,
The box is in static equilibrium, with a net force of 0 N.

It costs $7.15 to rent a kayak for 1 hour at a local state park. The price per hour stays the same for up to 5 hours of rental. After 5 hours, the cost decreases to $5.75 per hour.
How much would it cost to rent a kayak for 6 hours?
Answer:
$41.50
Step-by-step explanation:
multiply $7.15 by 5 for every hour then add the $5.75 to show how it decreased which will give you $41.50 for 6 hours
Answer:
$35.90
Step-by-step explanation:
(5.75 • 5) + 7.15
= (5 • 5) + (0.75 • 5) + 7.15
= (25 + 3.75) + 7.15
= 28.75 + 7.15
= (28 + 7) + (0.75 + 0.15)
= 35 + 0.90
= $35.90

How many solutions does 33x+99=33x-99 have
Answer:
No real solutions
Step-by-step explanation:
If you rearrange the equation:
33x - 33x = -99 - 99
0x = -198
Anything divided by zero is undefined/no real solution
Answer:
0
Step-by-step explanation:
33x + 99 = 33x - 99
→ Minus 99 from both sides
33x = 33x - 198
→ Minus 33x from both sides
0x = 198

Step-by-step explanation:
A student is learning about positive and negative numbers with manipulatives. Each black cube represents + 1 , and each white cube represents − 1 . If there are currently 15 black cubes on the student's desk, how many white cubes must the student add to the desk for the combined value of the cubes to represent 0 ?
Answer:
15 white cubes
Step-by-step explanation:
Given
[tex]White\ Cubes = -1[/tex]
[tex]Black\ Cubes = +1[/tex]
[tex]Number\ of\ Black\ Cubes = 15[/tex]
Required
Determine the number of white cubes needed to represent 0
To solve this question, we make use of the following equation.
[tex]Black\ Cubes +White\ Cubes = 0[/tex]
If there are 15 black cubes, the the 15 black cubes is worth: +1 * 15
Substitute +1 * 15 for the Black Cubes
[tex]+1 * 15 +White\ Cubes =0[/tex]
[tex]+15 +White\ Cubes =0[/tex]
Collect Like Terms
[tex]White\ Cubes = 0 - 15[/tex]
[tex]White\ Cubes = - 15[/tex]
Recall that 1 white cube is worth -1
So, the number of white cubes is:
[tex]Number = \frac{-15}{-1}[/tex]
[tex]Number = 15[/tex]
Hence, the student needs 15 white cubes
Which storm is likely to cause quick destruction along a narrow path?
hurricane
thunderstorm
tornado
Answer:
tornado bc they are narrow and can cause great destruction :) hope I helped !
A tornado is the storm that is likely to cause quick destruction along a narrow path.
What is storm?A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body.
Tornadoes are characterized by their rapidly rotating column of air that extends from the base of a thunderstorm to the ground.
They can cause widespread damage and destruction within a very short period, along a narrow path that can be just a few meters wide.
While hurricanes can produce powerful winds and storm surge that can cause significant damage and destruction, their effects are spread over a larger area, including a broad swath of coastal areas.
Thunderstorms can also produce damaging winds, hail, and flash flooding, but they usually affect smaller areas compared to hurricanes or tornadoes.
Hence, tornado is the storm that is likely to cause quick destruction along a narrow path.
