Answer: y = (1/2)*x - 1

Step-by-step explanation:

a linear relationship is something like:

y = a*x  + b, lets find the values of a and b.

We have that the output (y) must be 1 less than half of the imput (x), then our relation is:

y = (1/2)*x - 1

Answer:

The ferris wheel travelled 434.717 ft.

Step-by-step explanation:

Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:

radius = height/2 = 246/2 = 123 ft

The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:

length = r*(angle in radians)

length = 123*(9pi/8)

length = 434.717 ft

The ferris wheel travelled 434.717 ft.

The drama club is holding auditions for five different parts in a one act play. If 9 people audition, how many ways can the roles be assigned?

a. 362,880

b. 15,120

c. 126

d. 120

Answer:

b. 15,120

Step-by-step explanation:

In other to solve the question above, we would use the formula for permutation.

This is because when assigning 5 DIFFERENT roles to 9 people, the order of assigning the roles is important. The formula for permutation, is used when order is involved.

Permutation (n, r) = nPr = n!/(n - r)!

In the above question,

n = 9 people

r = 5 different parts

9P5 = 9!/(9 - 5)!

= 9!/4! = 9×8×7×6×5×4×3×2×1/ 4×3×2×1

= 362880/ 24

= 15,120

Therefore, the number of ways that the roles can be assigned is 15,120 ways

Answer:

78

Step-by-step explanation:

The IQR is quartile 3 - quartile 1. First, we need to find the mean of the dataset, which is 50 -- the fifth number. Then, the median of the dataset on the left of the fifth number is the first quartile, and the median of the dataset on the right is the third. We get Q1 to then be halfway between 30 and 50, or 40, and Q3 to be halfway between 56 and n, so Q3 = (56+n)/2. Since we need Q3-Q1=27, or (56+n)/2-40=27, we have (56+n)/2=67 and 56+n=134, so n = 134-56=78

Given that the area is 81 square inches, find out the length of the side of a square.

Answer:

It 2/5.

Step-by-step explanation:

Just did the question :)

The experimental probability of flipping a head after five flips of a coin can be calculated by finding the ratio of the number of times a head appears to the total number of flips.

In this case, since there are two possible outcomes - a head or a tail - the total number of flips is five. Let's say, after five flips, a head appears three times. The experimental probability of flipping a head would be calculated as 3 (number of heads) divided by 5 (total number of flips), which equals 0.6.  

Therefore, the experimental probability of flipping a head after five flips of the coin is [tex]0.6, or 60[/tex] %. It is important to note that the experimental probability may not accurately represent the theoretical probability, as it is based on a limited number of trials. The theoretical probability of flipping a head is 1/2, which is [tex]0.5 or 50[/tex]%.

Answer:

Step-by-step explanation:

Let x represent the distance between Earth and its moons.

Saturn’s rings span up to about (7.5 × 10^-1) of the distance between the Earth and its moons. It means that Saturn’s rings span is

(7.5 × 10^-1)x

If Saturn’s rings span up to 2.82 × 10^5 kilometers, it means that

(7.5 × 10^-1)x = 2.82 × 10^5

Dividing both sides of the equation by 7.5 · 10^-1, it becomes

x = (2.82 × 10^5)/(7.5 × 10^-1)

x = 3.76 · 10^5 km

Answer:

exponential decay

Step-by-step explanation:

exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.Exponential decay occurs when the amount of decrease is directly proportional to how much exists.

Answer:

c = [tex]\frac{1}{10}[/tex]

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

[tex] C = f+cm[/tex]

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

[tex] 3000=f+c15000, 3500=f+c20000[/tex]

Si restamos la segunda ecuación de la primera, tenemos que

[tex] 3500-3000 = f-f+(20000c-15000c)[/tex]

Luego

[tex] 500 = 5000c[/tex]

Entonces [tex] c = \frac{500}{5000} = \frac{1}{10}[/tex]

Si tomamos la primera ecuación, tenemos que [tex]3000-\frac{15000}{10} = f[/tex]. Es decir,

[tex] 3000-1500 = f = 1500[/tex]

Answer:

D: (18,0)

I got it right on Edge 2020

An equation is formed of two equal expressions. The correct option is D.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the two systems of equations,

y = -(1/3)x + 6

y = (1/3)x - 6

Substitute the value of y from equation one with two, we will get,

-(1/3)x + 6 = (1/3)x - 6

6 + 6 = (1/3)x + (1/3)x

12 = (2/3)x

x = (12×3)/2

x = 18

Substitute the value of x in any one of the equations,

y = (1/3)x - 6

y = (1/3)(18) - 6

y = 0

Hence, the solution of the system of equation is (18, 0).

Answer:

Last year we had M students.

This year we have N students.

Now, the question ask "by what percentage the number of students grow".

So we are considerating a growth, this means that we must think that M as the 100%.

Then we have that N - M is the difference between the students of last year and this year.

this means that this year we have N - M more students that last year, so the percentage of growth is:

((N - M)/M)*100%

Now you need to replace the values for N and M.

You also can notice that if N is smaller than M, you will have a negative percentage, this means that instead of a growth, we have a decrease in the number of students.

Answer:

(6,1)

Step-by-step explanation:

Just look for the terms with x and y in them. Divide their coefficients by two, and multiply by -1. And then put them in an ordered pair.

So in this case, -12x --> 6 and -2y --> 1

Obviously the more orthodox way would be to actually complete the square, but I'm lazy, this way is faster, and since this seems to be multiple choice, as long as you have the correct answer, it shouldn't matter.

The required centre will be at (6,1)

The standard equation of circle is expressed as:

x^2+y^2+2gx+2fy+c = 0

where (-g, -f) is the centre of the circle

Given the equation x^2 + y^2 – 12x – 2y + 12 = 0

Compare with the general to have;

2gx = -12x

g = -6

2fy = -2y

y = -1

Since centre is at (-g, -f), hence the required centre will be at (6,1)

Please refer to attached image for the graph of required circle.

Step-by-step explanation:

The center and radius equation of a circle is :

[tex](x-h)^2 + (y-k)^2 = (r)^2 ...... (1)[/tex]

Where the co-ordinates [tex](x,y)[/tex] from where the circle passes.

[tex](h,k)[/tex] is the co-ordinate of circle's center represented by O.

[tex]r[/tex] is the radius of circle.

Here, we are given that center of circle is at [tex](4,4)[/tex].

So, [tex]h = 4\ and\ k = 4[/tex].

and [tex]r = 3[/tex]

Hence, the equation (1) can be represented as :

[tex]\Rightarrow \left(x-4\right)^{2}+\left(y-4\right)^{2}=3^{2}\\\Rightarrow \left(x-4\right)^{2}+\left(y-4\right)^{2}=9[/tex]

Answer:

Step-by-step explanation:

Given

Diver is standing [tex]7\ m[/tex] above water

Diver is at a maximum height of [tex]h=7+2=9\ m[/tex] at [tex]t=2\ s[/tex]

So, at [tex]t=2\ s[/tex] his velocity is zero

After this he will be under free fall

using

[tex]s=ut+\frac{1}{2}at^2[/tex]

here [tex]u=0[/tex]

[tex]s=\frac{1}{2}\times 10\times (3)^2[/tex]

[tex]s=5\times 9=45\ m\quad \text{(not possible)}[/tex]

but the distance between the pool and Henry is [tex]9\ m[/tex]

[tex]9=\frac{1}{2}\times 10\times (t)^2[/tex]

[tex]t=\sqrt{1.8}[/tex]

[tex]t=1.34\ s[/tex]

So, he reaches pool at [tex]t=2+1.34=3.34\ s[/tex] after diving off the board

Answer:

Ignore the answer above, the correct answer is 4.5m.

Step-by-step explanation:

If you ignore all the useless information, you'll see that the parabola Henry creates has a vertex of (2,9) (because obviously the parabola opens downwards). Using this, we can deduce the vertex form of the equation for this parabola to be y=-a(x-2)²+9. This is because the vertex is always equal to (h,k), and the vertex form of any parabola is written as y=a(x-h)²+k. Now, you can solve for a to find it is 0.5, by using (0,7) as the y-intercept (aka the diving board, his starting location). Now, you can graph y=-0.5(x-2)²+9 by using mapping notation, (I find to be the easiest), or any other strategy you'd like. Once graphed, it is clear to see that when the parabola reaches 5 along the x-axis, (simpler if you think of the x-axis as time and the y-axis as height), it is plotted at 4.5 on the y-axis. This means that after 5 seconds, Henry is 4.5 meters above the water.

Answer:

(4/3) π units²  or  (b):  33.5 units²

Step-by-step explanation:

The area of a sector of a circle of radius r and central angle Ф is a fraction of the total area of the circle:  (Ф/[2π]) * πr².

Here we find the area of the circle to be A = π (8 units)².

                                                    60

Multiply that by the fraction  ------------- , or 1/6

                                                    360

We get:  (1/6) (π (8 units)² = (4/3) π units², or approximately 33.5 units²

Answer:

E

Step-by-step explanation:

If you add 22 onto the sum of all the points and divide by the amount of games (6), you get 12.

The score she must get during the 6th game to have a mean of 12 point score per game is 22.

The mean is the average of numbers.

Mathematically, it is represented as follows;

mean = sum of terms / number of terms

Therefore, to get a mean of 12 point score per game the 6th score can be calculated as follows:

let

x = 6th score

Hence,

8 + 12 + 10 + 6 + 14 + x   / 6 = 12

50 + x / 6 = 12

cross multiply

12 × 6 = 50 + x

72 = 50 + x

72 - 50 = x

x = 22

Therefore, the score is 22.
