In a relay race, the probability of the Galaxy team winning is 22%. In another unrelated relay race, the probability of the Komets team winning is 47%. If the possibility of a tie is not an option, the probability of the Komets losing their race and the Galaxy winning theirs is ?%

Answers

Answer: There is 12% chance that Komets losing their race and the Galaxy winning theirs.

Step-by-step explanation:

Since we have given that

Probability that Galaxy team winning = 22%

Probability that Komets team winning = 47%

Probability that Komets team losing = 100-47=53%

We need to find the probability of the Komets losing and Galaxy winning their game.

So, Probability that Komets losing and Galaxy winning their game is given by

$(22)/(100)* (53)/(100)\n\n=(1166)/(10000)\n\n=0.1166\n\n=0.12=12\%$

Hence, there is 12% chance that Komets losing their race and the Galaxy winning theirs.

Answer: y = (4/3)x + 2

======================================================

Explanation:

The given equation is y = (-3/4)x - 2. Comparing it to y = mx+b, the slope is m = -3/4

Flip the fraction and the sign to go from -3/4 to 4/3. This is the perpendicular slope. Multiplying the two slopes gets (-3/4)*(4/3) = -1.

Rule: the original slope and perpendicular slope always multiply to -1, assuming neither line is vertical or horizontal.

We'll use the point (x,y) = (3,6) and the perpendicular slope m = 4/3 to find the y intercept b

y = mx+b

6 = (4/3)(3) + b

6 = 4+b

6-4 = b

2 = b

b = 2

The y = mx+b equation becomes y = (4/3)x + 2 which is the slope intercept form of the perpendicular line.

Extra info:

If you want to convert to standard form Ax+By = C, then you could do the following steps

y = (4/3)x + 2

3y = 4x + 6 ... multiply everything by 3 to clear out the fraction

3y - 4x = 6

-4x + 3y = 6

4x - 3y = -6 ... multiplying both sides by -1; this is to make A > 0

The vertex of this parabola is at (-2,-3). When the y-value is -2,the x-value is -5. what is the coefficient of the squared expression in the parabola's equation?

Answers

Answer:

It is -3

Step-by-step explanation:

I just missed it and it told me the right answer and the dude before me made me get it wrong. APEX

Hello,

Vertex=(-2,-3)

Equation of the parabola is y=k(x+2)²-3
(-5,-2) is a point of the parabola
==>-2=k(-5+2)²-3==>3-2=k*9==>k=1/9

Equation is y=1/9* (x+2)² -3

The coefficient of the squared expression in the parabola's is 1/9

The sum of two numbers is 37. the greater number is 5 more than three times the lesser number. what is the lesser of the two numbers?

Answers

Hi there!

In order to solve this problem, we should first write this into expressions.

Let x = the bigger number
Let y = the smaller number

x + y = 37
x = 3y + 5

Now, we can use substitution of the system ofinequalities to solve.

We substitute the value of x into the equation.

3y + 5 + y = 37

Now, we simplify.

4y + 5 = 37
4y = 32
y = 8

So, 8 is the answer.

Hope this helps!

3y+y+=37 that’s the answer to that

Can a system of linear equation have exactly 2 solutions ? why or why not?

If I have the height and volume of a cylinder, how do I find the radius? or diameter?

Answers

If you have the volume, that's a pretty good giveaway that you ought to use
the formula for the volume of a cylinder, since it involves all the other things ...
the things you're given, and the things you need to find. If you know the formula
for the volume of a cylinder, you can whip out the answer in a second. If you don't
know the formula, then you are toast.

Volume of a cylinder = (pi) (radius)² (length or height)

Divide each side of the equation by (pi) x (height) and you have

(Radius)² = Volume / (pi x height)

You HAVE volume and height, so you can use this equation to calculate
the radius. Once you have that, if you need the diameter, it's just double
the length of the radius.

That's how.

$V=\pi r^2h\n r^2=(V)/(\pi h)\n r=\sqrt{(V)/(\pi h)}$
