Answer:

A third place vote is worth 1 point

Step-by-step explanation:

Let the number of points for a first place vote be x, number of points for a second place vote be y and the number of points for a third place vote be z.

So, by multiplying the number of points by the number of what the point is worth and adding all together, we shall have the total points;

Hence, we have the following equation systems;

23x + 5y + z = 131

5x + 17y + 4z = 80

x + 5y + 15z = 35

These are the three equations we need to solve simultaneously to get the value of z

From equation 3, x = 35 -5y -15z

Insert this into the first two equations;

23 ( 35 -5y -15z) + 5y + z = 131

5(35-5y-15z) + 17y + 4z = 80

805 - 115y -345z + 5y + z = 131

805-131 = 115y + 345z -5y - z

674 = 110y + 344z ••••••••••(*)

The second equation now becomes the following;

5(35-5y-15z) + 17y + 4z = 80

175 -25y -75z + 17y + 4z = 80

175-80 = 25y + 75z -17y -4z

95 = 8y + 71z

8y + 71z = 95 •••••••••••(**)

So we have to solve x and xx simultaneously;

110y + 344z = 674

8y + 71z = 95

110/8 = 13.75 , so multiply equation xx by 13.75 and equation x by 1

110y + 344z = 674

110y + 976.25z = 1306.25

Subtract equation xx from x

(976.25z - 344z) = (1306.25 -674)

632.25z = 632.25

z = 632.25/632.25

z = 1

Answer:

a. We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.

b. This happens because, there are two possible values for the nth root of a set of even numbers.

Step-by-step explanation:

a. How can you tell if there will be more than one solution for the geometric means?

We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.

Since geometric means of n numbers from x₁,x₂, x₃,...,xₙ is

GM = ⁿ√x₁,x₂, x₃,...,xₙ .

Now, if n is an even number, the geometric means would have both a positive and negative value.

For example, if n = 2,

GM = ±√x₁,x₂ which is

GM = +√x₁,x₂ or -√x₁,x₂.

b. Why does this happen with the geometric means?

This happens because, there are two possible values for the nth root of a set of even numbers. For example if n = 2,

GM = ±√x₁,x₂ which is

GM = +√x₁,x₂ or -√x₁,x₂.

So, we have two possible values for the geometric means.

Answer:

-44

Step-by-step explanation:

So you want to plug 2 in for t, so the equation should now look like:

[tex]2^{2}[/tex] - 44 - 4

No all you have to do is solve

[tex]2^{2}[/tex] = 4

4 - 44 = -40

-40 - 4 = -44

Answer:

-44

Step-by-step explanation:

t=2, t² - 44 - 4

1. substitute in the value to the variable: 2² - 44 - 4

2. using PEMDAS, solve the equation: 2² - 44 - 4 = 4-44-4 = -40-4= -44

(evaluate the exponent, then subtract)

Step-by-step explanation:

(a)

To find the first 4 terms substitute n = 1, 2, 3, 4 into the n th term formula.

a₁ = 1 + 5 = 6

a₂ = 2 + 5 = 7

a₃ = 3 + 5 = 8

a₄ = 4 + 5 = 9

For the 10 th term substitute n = 10, that is

a₁₀ = 10 + 5 = 15

The first 4 terms are 6, 7, 8, 9 and the 10 th term is 15

(b)

Substitute n = 1, 2, 3, 4 and 10 into the n th term formula

a₁ = 2(1) - 1 = 2 - 1 = 1

a₂ = 2(2) - 1 = 4 - 1 = 3

a₃ = 2(3) - 1 = 6 - 1 = 5

a₄ = 2(4) - 1 = 8 - 1 = 7

a₁₀ = 2(10) - 1 = 20 - 1 = 19

The first 4 terms are 1, 3, 5, 7 and the 10 th term is 19

Answer:

1. 7

Step-by-step explanation:

1. 8y= 37+ 35

Subtract 3y from both sides of the equation:

8y - 3y = 3y + 35 - 3y

simplify:

combine like terms

than combine like terms again

5y= 35

Divide both sides of the equations by the same term:

5y = 35

[tex]\frac{5y}{5} = \frac{35}{5}[/tex]

simplify:

cancel terms that are in both the numberator and denominator

Answer:

6 seconds

Step-by-step explanation:

Initial distance of Mario from motion detector = 2 ft

Speed of Mario = 1.5 ft/sec

Total distance of Mario from motion detector = 11 ft

Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft

Given that:

Distance = 9 ft

Speed = 1.5 ft/sec

Formula:

[tex]Distance = Speed \times Time[/tex]

[tex]\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}[/tex]

So, at 6 seconds, Mario will be 11 ft from the motion detector.

x<=40

Which fits the problem!

Hope this helps

For a given function f(x) we define the domain as the set of possible values of x that we can use in the function.

Here we will find that the domain is D: [20h, 40h]

We know that Ally wins $18 per hour, and she has two restrictions:

She cant' work more than 40 hours.

She needs to work at least 20 hours.

Then her weekly salary can be written as:

s(x) = $18*x

Where x is the number of hours that she works each week.

With the above restrictions we have:

20h ≤ x ≤ 40h

Then the domain is:

D: [20h, 40h]
