Answer:
There are 220 ways by which the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal
Step-by-step explanation:
From the question, we have;
The number of gymnast in the Olympic women's competition = 15
The number of the gymnast who are Americans = 4
The number of medals awarded = 3 medals
The number of ways hat the medals can be awarded to the three of the gymnast if exactly one of the Americans wins a medal is given as follows;
The number of ways one of the medals can be won by one of the four Americans = ₄C₁ = 4 ways
The number of ways the other two medals can be won by the remaining 11 gymnast = ₁₁C₂ = 55 ways
Therefore, the total number of ways, 'N', the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal is given as follows;
N = ₄C₁ × ₁₁C₂
∴ N = 4 × 55 = 220

how many solutions does the graph above show?
a. one
b. none
c. infinite
Answer:
infinite
Step-by-step explanation:
The line can be represented by the equation y=-2/3x-2 since there are no other lines it would be infinite. if there was a line with the same slope and a different y-intercept the answer would be none as the lines never intersect. for the equation there are ifinitly many!
for example any point that that lone touches is a solutions so there is not one but many answers.

Ian has a goal to save $2000. He already has 1/5 of his goal. How much more money must Ian save to achieve his goal?
Answer:
1,000
Step-by-step explanation:
If Ian has 1/5 of his goal which is $2,000 just divide $2,000 by 1/5 which is 1,000. hope this helped
Answer:
1/5 of 2000 is 400 (2000/5=400)
2000-400 is 1600.
he needs to save another $1600

ALGEBRA 2!!!!!!!HELP
Answer:
x = - 1, x = - 11
Step-by-step explanation:
Given
2| x + 6 | - 4 = 6 ( add 4 to both sides )
2|x + 6 | = 10 ( divide both sides by 2 )
| x + 6 | = 5
The absolute value function always gives a positive result, but the expression inside can be positive or negative, that is
x + 6 = 5 or - (x + 6) = 5
solve both
x + 6 = 5 ( subtract 6 from both sides )
x = - 1
or
- (x + 6) = 5 , that is
- x - 6 = 5 ( add 6 to both sides )
- x = 11 ( multiply both sides by - 1 )
x = - 11

Find the values for x and y in rectangle SLIM.
Answer:
x = 25
y = 65
Step-by-step explanation:
(I did it on Math Nation)
180 = 130 + 2x
50 = 2x
x = 25
180 = 50 + 2y
130 = 2y
y = 65

What is the perimeter of the figure? Use 3.14 for pi
Answer:
42.84 cm
Step-by-step explanation:
It would be easiest to split this first. To find the circumference of a circle, it is 2πr.
d= 12
r= 6
C= 2π6
C= 12π
Divide by 2 because you are only trying to get the circumference of half the circle.
C= 6π
Now you can add all the other sides to find the total perimeter.
P= 6(3.14) + 10 + 6 + 8
P= 42.84 cm

I really really need help with this and no one is answering. I've looked everywhere for how to do this and I fell like its simple but I can't find it. given -2+4i, express the complex number in polar form. I know the answer is 2 root 5(cos2.03 + isin2.03), but I don't know where the 2.03 comes from. Can someone explain please?
Result:
Complex number:
The polar form of z is:
Explanation:
z = −2 + 4i
z = 4.4721 · (cos 117o + i · sin 117o)
The polar form of the complex number z = a + bi is:
z = r · (cos θ + i · sin θ)
where, r is the modulus of z and θ is an argument of z. The moduo for a = −2 and b = 4 is:
r = a2 + b2 = · · · = 4.4721 To find argument θ we use one of the following formulas:
b θ=arctan a ifa>0
b o θ=arctan a +180 ifa<0
θ=90o ifa=0andb>0 θ=270o ifa=0andb<0
Inthisexample: a=−2andb=4so:
θ=arctan a +180
θ=arctan 4 +180o −2
b o
θ = arctan (−2) + 180o θ ≈ 117o

The sum of two numbers is 17 and their difference is 5, what are the two numbers?
Answer:
11, 8
Step-by-step explanation:
x + y = 17
x - y = 5
The "y" cancels out when you add the two equations and you end up with:
2x = 22
x = 11
Then, plug the "x" back into one of the equations to find "y":
11 + y = 17
y = 6

Answer:
y-intercept is (0, -2) and asymptote of y = -2.5
Step-by-step explanation:
If you substitute 0 in for x and simplify, then you will have the y-intercept
y = [tex]\frac{1}{2} (7)^{0} - 2.5 = \frac{1}{2} (1) - 2.5 = \frac{1}{2} - 2.5 = -2[/tex]
The y-intercept is (0, -2)
If the -2.5 were not there, then the graph would have an asymptote at y = 0 or the x-axis
The -2.5 moves the graph down 2.5 units so that y = -2.5 is the asymptote
Therefore, the first answer is correct

Who can answer this??
Ths question is not complete but I will try my best to guide you through it so you can answer it. So what the question is asking you to do is that you have to plug in the coordinates into the equation. I don't want to give you an incorrect answer so I will explain it and you can do it yourself with the full question. First use the second equation as it is a full equation with an equal sign. Once plugged in you can find that c and d do not make the second equation true. A and B both complete the second equation. This means that either A or B is the answer. Since the first equation does not have an equal sign meaning it is not complete I can not answer it and I am sorry. But I have cut the answer down for you to A and B. If this answer helped you in the slightest please check out my channel The Game Rater. Thank you and I appreciate it.
