Answer:

both are correct

Step-by-step explanation:

theyre the same answer I think the questions wrong

Answer:

i.  P = -800t + 29900

ii.  as an inequality: 0≤t≤37.375;  interval notation: [0,37.375]

iii.  as an inequality: 0≥P≥29900;  interval notation: [0,29900]

iv.  the population decreases at a rate of 1600 people every 3 years

v.  2010

Step-by-step explanation:

i. a) use the points *(4,26700) and **(12,20300) to find the slope (m)

      *: the year 1995(4 years after 1991) and the population that year

      **: the year 2003(12 years after 1991) and the population that year

      m = (20300-26700)/(12-4) = -6400/8 = -800

  b) use one of the points and m in (a) to find b

      26700 = -800(4) + b

      26700 = -3200 + b

      29900 = b

ii. starting value for domain will be 0 since 1991 is year 0. Find the ending domain value by using P=0 and solving the equation for t:

   0 = -800t + 29900

   800t = 29900

   t = 37.375

iii. population starts at a high of 29900 people and can't go lower than 0 people.

iv. the slope is given in (population change) / (number of years)

v. make P=14700 and solve the equation for t

   14700 = -800t + 29900

   800t = 15200

   t = 19 (19 years after 1991)

The Banzhaf power distribution value in the fraction is,

Player 1:  = 0.6

Player 2:  = 0.2

Player 3:  = 0.2.

What is the distribution?

The mathematical expression known as a distribution function expresses the likelihood that a system would adopt a certain value or range of values. The traditional examples include games of chance.

List of winning coalitions:

1. P1, P2, P3

2. P1, P2

3. P1, P3

No. of times P1 is critical = 3 (P1 is critical all 3 times as it has veto power)

No. of times P2 is critical = 1 (in the second coalition)

No. of times P3 is critical = 1 (in the third coalition)

Total no. of critical times = 3 + 1 + 1 = 5

Banzhof Power Distribution:

Player 1: No. of times P1 is critical/Total no. of critical times

              = 3/5 = 0.6

Player 2: No. of times P2 is critical/Total no. of critical times

              = 1/5 = 0.2

Player 3: No. of times P3 is critical/Total no. of critical times

              = 1/5 = 0.2

Hence, the Banzhaf power distribution value in the fraction is,

Player 1:  = 0.6

Player 2:  = 0.2

Player 3:  = 0.2

The number of cows is 12 and number of chickens are 36.

A "system" of equations is a set or collection of equations that you deal with all together at once.

Given that, Farmer John has cows and chickens on his farm. His farm animals have 120 legs and 48 heads total.

Let the number of chickens be x and that of cows be y,

A cow has 4 legs and that of chickens have 2,

Setting the equations, we get,

2x+4y = 120

x+2y = 60

x+y = 48

Solving the equation by elimination, we get,

2y - y = 60 - 48

y = 12

Therefore, x = 36

Hence, The number of cows is 12 and number of chickens are 36.

The number of drinks and the number of candies that Carter bought are 6 and 2 respectively.

In order to determine the number of drinks and the number of candies that Carter bought, we would have to write a system of linear equation and assign variables to the number of drinks and number of candies respectively, and then translate the word problem into algebraic equation as follows:

Since each drink costs $4.50 and each candy costs $3 and Carter bought 3 times as many drinks as candies;

x = 3y                        .......equation 1.

4.50x + 3y = 33          .......equation 2.

Substituting equation 1 into equation 2, we have:

4.50(3y) + 3y = 33

13.50y + 3y = 33

16.50y = 33

y = 33/16.50

y = 2 candies.

For the value of x, we have:

x = 3(2)

x = 6 drinks.

:On hand she has a 20% acid solution and a 50% acid solution. How many ml of each solution should sheStep-by-step explanation:this is the answer

A chemist needs 40mL of 20% acidic solution and 60mL of 50% acidic solution.

The percentage is the ratio of number expressed as a fraction of 100.

Assume chemist needs x mL of 20% of acidic solution and y mL of 50% acidic solution.

A total of 100mL solution is to be created.

x+y=100

x=100-y

The concentration of 20% acidic solution will be 0.2x, concentration of 50% acidic solution will be 0.5x and the sum of their concentrations should be 0.38(100).

0.2x+0.5y=0.38(100)

0.2x+0.5y=38

Substitute x=100-y into the obtained equation.

0.2(100-y)+0.5y=38

20-0.2y+0.5y=38

20+0.3y=38

0.3y=18

y=18/0.3

y=60

Substitute y=60 into x=100-y.

x=100-60

=40

So, the chemist needs 40mL of 20% acidic solution and 60mL of 50% acidic solution.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Solve the expression,

x² – 3x − 2 = x + 3

Now, We can simplify as;

x² – 3x − 2 = x + 3

x² – 3x − 2 - x - 3 = 0

x² - 4x - 5 = 0
