The probability of having one white ball is 1/20 or approximately 0.05.
To find the probability of selecting one white ball out of three balls, you need to know the number of white balls in the box and the total number of balls in the box. You also need to know whether the balls are being selected randomly or not.
Assuming that there is only one white ball in the box and the rest are some other color, and that the balls are being selected randomly.
The probability of selecting one white ball out of three would be:
Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)
Since there is only one white ball, there is only one way to select one white ball out of three. The total number of ways to select three balls out of six is 6 choose 3, which is equal to 20.
Therefore, the probability of selecting one white ball out of three would be
Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)
Probability = 1/20
Probability = approximately 0.05.

In order to prove triangle similarity by AAA what does X have to equal?
Answer:
x has to be equal to 12
Step-by-step explanation:
In other to prove that the triangles are similar, the values of the angles at certain points must be equal
for example, the angle at the top vertices should be equal
So, we have it that;
6x = 3x + 36
6x-3x = 36
3x = 36
x = 36/3
x = 12
Suppose you had to decide between an apartment that cost $800/month for a month-to-month contract, or $650 for an annual contract. The annual contract includes a 2- month early termination penalty if you leave before 12 months
Answer:
Step-by-step explanation:
Incomplete question, but if my guess is correct, you're trying to determine which is a better deal between the two. I will go with the second one. The $650/month rent.
I choose so because, $800/month totals to $9600 at the end of the year. While $650/month totals to $7800 per year. Again, with the $650/month, if you try to leave before the end of the year, say 11 months even, you pay a penalty of $1300, which still leaves you on the profit side. And the whole idea of choosing is to find which is more beneficial and cost effective.
A model rocket is launched from
the top of an observation tower
that is 75 feet high. The height
of the rocket, h(t), is
determined by the function
h(t)--16r2 + 48t +75 where t is
the number of seconds elapsed
since the rocket was launched.
When does the rocket land on
the ground? Round to the
nearest hundredth.
Answer:
>>> t = 3/2 - sqrt(111)/4
>>> t = 3/2 + sqrt(111)/4
Step-by-step explanation:
-16r^2 + 48t +75=0
>>> t = 3/2 - sqrt(111)/4
>>> t = 3/2 + sqrt(111)/4

What is the probability that a randomly selected student
is a junior who takes the bus?
?
P(Junior' n Take the bus)
Answer:
The answer is 1/5
Step-by-step explanation:
Trust me.
The probability that a randomly selected student is a junior who takes the bus is [tex]\frac{1}{5}[/tex] .
What is probability?Probability or chance is how likely something is to happen. If something has a low probability, it is unlikely to happen. If something has a high probability, it is likely to happen.
[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]
Given,
Total number of students = 100
Number of students who are juniors and take bus = 20
[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]
Probability of junior students who take bus = [tex]\frac{20}{100}[/tex]
Probability of junior students who take bus = [tex]\frac{1}{5}[/tex]
Hence, The probability that a randomly selected student is a junior who takes the bus is [tex]\frac{1}{5}[/tex] .

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term.
10, 11, 12, 13
Answer:
[tex]9 + n[/tex]
Step-by-step explanation:
Well it's an arythmetic sequence, so it will look like:
[tex]a + d\cdot n[/tex]
Note that the first element is:
[tex]a + d\cdot 1[/tex]
and the second element is:
[tex]a + d \cdot 2[/tex]
So the difference between the two gives us d!
[tex]d = 11 - 10 = 1[/tex]
Now let's find the [tex]a[/tex]:
[tex]a + d\cdot 1 = 10\\a + 1 \cdot 1 = 10\\a + 1 = 10\\a = 9[/tex]

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1256.00 square feet? Use 3.14 for pi
Answer:
20 feet
Step-by-step explanation:
A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1256.00 square feet? Use 3.14 for pi
From the above question, we are to find the radius of the circular pattern
The formula for the Area of the circle = πr²
To find r
r² = A/π
r = √A/π
In the above question, Area = 1256 square feet
π = 3.14
r = √1256/3.14
r = √400
r = 20 feet
The radius/distance from the sprinkler that can spread water = 20 feet

Answer:
Number 6 would be (a) 88 degrees
Number 7 would be (c) 45 degrees
Step-by-step explanation:
What is this Geometry? I haven't done this in so long so i went to look it up online and was shocked because of how much i was overthinking it.
For number 6, since we already have the angle listed as 44 degrees, to find the arc degrees, we would multiply the 44 by two. The formula is basically mAB=2(m<C)=88.
For number 7, we already have the arc degrees, so we would have to divide by two in this case to find the angle. The formula for this would be m<X=1/2(mYZ)=45.
Intr un album numarul de fotografii s a micsorat cu 50%. Cu cat trebuie sa se mareasca pentru a reveni la numarul initial? Raspunsul trebuie sa fie 100%.
Răspuns:
100%
Explicație pas cu pas:
Permiteți numărul inițial de fotografii = x
x - 50% din x = x - 0,5x = 0,5x
0,5x + câte% din 0,5x = x
x - 0,5x = y% de 0,5x
0,5x / 0,5x = 1
Prin urmare,
100% = 1
Prin urmare, x trebuie mărit cu 100% pentru a reveni la numărul original.
