select the correct descriptor of the following problems: from a pack of 52 cards, two cards drawn together at random. What is the probability od both the cards being kings?
Answer:
[tex]\frac{1}{221}[/tex]
Step-by-step explanation:
We have to note that there are 4 kings in a deck of 52 cards.
This makes the probability of choosing a king the first time [tex]\frac{4}{52} = \frac{1}{13}[/tex].
We now know that we can choose another king from the deck, but it's important to note that it's not a [tex]\frac{1}{13}[/tex] chance. We now only have 51 cards in the deck, and 3 kings left. This means the probability of choosing a king now is [tex]\frac{3}{51} = \frac{1}{17}[/tex].
To find the probability of doing both these, we need to multiply the fractions.
[tex]\frac{1}{13}\cdot\frac{1}{17}=\frac{1}{221}[/tex]

Find the asymptotes of the hyperbola described by the equation: y2/9 - x^2/81=1. ANSWERS ATTACHED, due in 2 HOURS, will give Brainliest!
Answer:
Solution : y = ± 1/3x
Step-by-step explanation:
Remember that the equation of a hyperbola is in the form (y - k)² / a² - (x - h)² / b² = 1. Therefore we have a² here = 9, and b² here = 81.
To determine the asymptotes we can use the equation y = k ± a/b(x - h). What makes this equation really simple, is that k = 0 and h = 0, giving us y = ± a/b(x). Let's isolate a and b given a² = 9, and b² = 81 --- (1)
a² = 9
a = 3
b² = 81
b = 9
Therefore our asymptotes will be in the form y = ± a/b(x) = ± 3/9(x) = ± 1/3x. Our solution is thus option a.

the slope and y intercept of 3y+6x=18
Answer:
slope: -2
y-intercept: 6
Step-by-step explanation:
First, put the equation into slope intercept form.
Slope-intercept form: y = mx + b
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 6x from both sides:
3y + 6x (-6x) = 18 (-6x)
3y = -6x + 18
Next, divide 3 from both sides. Remember to divide from all terms:
(3y)/3 = (-6x + 18)/3
y = (-6x)/3 + (18)/3
y = -2x + 6
Slope-intercept form: y = -2x + 6
Again, note the slope-intercept form.
> Slope-intercept form: y = mx + b
The variables:
y = (x ,y)
m = slope
x = (x , y)
b = y-intercept
Your answers:
slope: -2
y-intercept: 6

There are 75 people in a room. Of these people, 2/5 are from Germany. If 4/9 of the people who are not from Germany are from France, how many of the people in the room are from neither Germany nor France
Answer:
25 people are not from Germany or France.
Step-by-step explanation:
1. You first want find out what is the number of people from Germany.
So you would find...
2/5 of 75
or
2/5*75= 30 people from Germany
2. Next you want to to find out the number of people from France.
So you would do the following...
75-30=45 (Subtract the number of people from Germany from 75 so you can get the total number of people from France and other countries)
4/9 of 45 to find the number of people from France.
4/9 *45= 20
3. Lastly you need to find the people who are from neither of the countries listed above.
Add 30+20= 50
Then subtract that number from 75.
75-50= 25 people who are from neither France or Germany.

Ship A and Ship B are 120 km apart when they pick up a distress call from another boat. Ship B estimates that they are 70 km away from the distress call. They also notice that the angle between the line from ship B to ship A and the line from ship A to the distress call is 28°. What are the two possible distances, to the nearest TENTH of a km, from ship A to the boat?
Answer:
The two possible distances from Ship A to the distress call boat are 64.4 km and 147.5 km
Step-by-step explanation:
The given parameters are;
The distance between Ship A and Ship B = 120 km
The distance of the distress call from Ship B = 70 km
The angle made between the line from Ship A to B and the line from Ship A to the distress call = 28° = Opposite angle to the line from the location of the distress caller to Ship B
Therefore;
70/(sin(28°)) = 120/(sin(x))
Where;
x = The angle opposite the line from Ship A to B
sin(x) = ((sin(28°))×120)/70 = 0.805
x = sin⁻¹(0.805) = 53.59°
Therefore, the angle opposite the line from Ship A to the distress caller, r = 180 - (28 + 53.59) = 98.4°
From sin rule, we have;
70/(sin(28°)) = r/(sin(98.4°))
r = (70/(sin(28°)))×(sin(98.4°)) = 147.5
However by cosine rule, we have;
70² = 120² + r² - 2×120×r × cos(28°)
4,900 = 14,400 + r² - 211.907·r
r² - 211.907·r + 14,400 - 4,900 = 0
r² - 211.907·r + 9,500 = 0
Factorizing, we have;
[tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]
[tex]r = \dfrac{211.907\pm \sqrt{211.907^{2}-4\times 1\times 9,500}}{2\times 1}[/tex]
r = 64.406 km or 147.501 km
Which gives;
The distance of the line from Ship A to the distress caller = 64.4 km or 147.5 km to the nearest tenth.
The two possible distances from Ship A to the distress call boat = 64.4 km and 147.5 km

9-2x=7x
How do I solve for x?
Answer:
The answer to the equation is 1.
Step-by-step explanation:
When having an algebraic equation, you have to move all of the variables on one side. Therefore, you can move the -2x or the 7x. However, to make a positive number, I would recommend to move the -2x.
To move the -2x to the other side, you add 2x to the both sides of the equation. Since the original equation is 9-2x=7x, you will add the 2x to it, so your equation will now look like this: 9-2x+2x=7x+2x. Once simplifying that down, you will have 9=9x. Then, you can divide the coefficient, so the 9 on the left side, and the 9 on the right side. After this, you will have 1=x. AKA x=1, which is the answer to the equation!
The solution to the equation 9 - 2x = 7x is x = 1 as per the algebraic operations.
To solve the equation 9 - 2x = 7x for x, we need to isolate the variable on one side of the equation. Here's the step-by-step process:
Start by combining like terms. Add 2x to both sides of the equation to move the variable terms to one side:
9 - 2x + 2x = 7x + 2x
9 = 9x
Divide both sides of the equation by 9 to isolate x:
9/9 = 9x/9
1 = x
Therefore, the solution to the equation 9 - 2x = 7x is x = 1.
By performing the necessary algebraic operations, we found that x is equal to 1. This value satisfies the original equation, making it the solution. It's important to check the solution by substituting x = 1 back into the original equation to ensure that it holds true. In this case, when we substitute x = 1 into the equation, we have 9 - 2(1) = 7(1), which simplifies to 7 = 7, confirming that x = 1 is indeed the correct solution.

The measures of the sides of a triangle are 20 24 and 30. Find the measures of the segments former where the bisector of the smallest angle meets the opposite side.
Answer:
One segment is 8.89 long and the other one is: 11.11 long
Step-by-step explanation:
Recall that the bisector of a triangle divides the opposite side it intersects into two segments that are proportional to the other two sides of the triangle.
In our case the bisector is generated on the angle opposite to the size 20 side (it is the smallest angle in the triangle since it is opposite to the smallest side). This bisector divides the side of length 20 into a segment of length x and a segment of length 20-x.
The proportionality indicated by the bisector theorem gives;
[tex]\frac{20-x}{x} =\frac{30}{24}[/tex]
and we can solve for "x":
[tex]\frac{20-x}{x} =\frac{30}{24}\\24\,(20-x)=30\,x\\480-24\,x=30\,x\\480=54\,x\\x=480/54\\x\approx8.89[/tex]
Then the other segment is: 20 - 8.89 = 11.11

3/4 - 1/2n =5/8. solve for n
The solution to the equation (3/4) - (1/2)n = 5/8 is n = 1/4 as per the rule of fraction's operations.
To solve the equation (3/4) - (1/2)n = 5/8 for n, we can follow these steps:
Start by subtracting 3/4 from both sides of the equation:
(3/4) - (1/2)n - 3/4 = 5/8 - 3/4
Simplifying, we have:
(1/2)n = 5/8 - 6/8
Combine the fractions on the right-hand side:
(1/2)n = -1/8
To eliminate the fraction coefficient, multiply both sides by -2:
(-2)(-1/2)n = (-2)(-1/8)
This gives us:
n = 2/8
Simplify the right-hand side:
n = 1/4
Therefore, the solution to the equation (3/4) - (1/2)n = 5/8 is n = 1/4.
It's important to note that when solving equations involving fractions, it's crucial to perform the same operation on both sides of the equation to maintain the equality. By isolating the variable n on one side, we were able to find its value.
