Answer:

(4,0)

Step-by-step explanation:

So we have the system of equations:

[tex]y=-2x+8\\y=x-4[/tex]

To solve, we can use substitution.

Substitute the second equation into the first. So:

[tex]x-4=-2x+8[/tex]

Add 2x to both sides. The right cancels:

[tex]3x-4=8[/tex]

Add 4 to both sides:

[tex]3x=12[/tex]

Divide both sides by 3:

[tex]x=4[/tex]

Now, let's substitute this back into the second equation to find y:

[tex]y=x-4[/tex]

Substitute 4 for x:

[tex]y=4-4[/tex]

Subtract:

[tex]y=0[/tex]

So, our solution is (4,0).

And we're done!

Answer:

0.006

Step-by-step explanation:

This is the answer because:

Short Way:

1) We know 3 x 2 is 6

2) When we multiply with zeros, how many ever zeros there are in the factors together, should be in the answer. In this case, in the answer we should have 3 zeros, one before the decimal point and two after the decimal point, because in 0.02 there are two zeros while in 0.3 there is only one zero.

3) Finally, the answer would be 0.006

Long Way:

1) You can do long multiplication to solve for the answer.

2) 0.02

   × 0.3

Is 0.006 because 3 x 2 is 6, and then 3 x 0 is 0 and then 3 x 0 is 0.

006

+0000

0.006

Remember to put a decimal point.

Answer:

The commission made is $104

Step-by-step explanation:

Here, given the payment analysis, we want to know the total pay for a day in which 12 demonstrations were made.

From the question, we can deduce the following;

For the first 7 demonstrations , $7 is paid

Now for the remaining 5 out of the total 12, the amount paid per demonstration is $11

So the total commission earned will be;

$7(7) + $11(5)

= $49 + $55 = $104

Answer:

Step-by-step explanation:

Let the probability of winning from left side be L and from right side by R .

Let the probability of winning by king be K .

Given information can be summarised as follows :

P(L) = .6

P(R) = .75

P K/(L∩R)=.98

P K/(L∩R')= .8

P K/(L'∩R) = .5

P K/(L∩R)' = .2

Probability of win by King can be summarised as follows .

P(k) = P(L∩R) x P K/(L∩R) + P(L∩R') x P K/(L∩R') + P(L'∩R) x P K/(L'∩R) + P(L∪R)' x P K/(L∪R)'

P(L∩R) = .6 X .75 = .45

P(L∪R) = P(L) +P(R) -  P(L∩R)

= .6 +.75 - .45 = .90

P(L∪R)' = 1 - P(L∪R) = .10

P(L∩R') = P(L)  - P(L∩R) = .6 - .45 = .15

P(L'∩R) = P(R) - P(L∩R) = .75 - .45 = .30

P(k) = P(L∩R) x P K/(L∩R) + P(L∩R') x P K/(L∩R') + P(L'∩R) x P K/(L'∩R) + P(L∪R)' x P K/(L∪R)'

= .45  x .98 + .15 x .8 + .30 x .5 + .1 x .2

= .441 + .12 + .15 + .02

= .73 approx .

Answer: 161, 25,-10,-31,-32,-301

Step-by-step explanation:

44.2%= 287

Let the total attempt = x

(287/x) ×100 = 44.2

287/x = 44.2/100

287/x = 0.442

x = 287/0.442

Answer:

The second choice, [tex](-1,\, 12)[/tex].

Step-by-step explanation:

Note, that the expression [tex]y = f(x)[/tex] is an equation. A point [tex](x,\, y)[/tex] is on the graph of [tex]y = f(x)\![/tex] if and only if the value of [tex]x[/tex] and [tex]y[/tex] satisfy this equation; that is: in other words, the [tex]y\![/tex]-coordinate of that point (the second number in the tuple) should be equal to [tex]f(x)[/tex], which is equal to [tex](-3\, x +9)[/tex] (evaluated where [tex]x\![/tex] is equal to the first number in the tuple.

For each tuple in the choices, calculate the value of [tex]f(x)[/tex] where [tex]x[/tex] is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on [tex]y = f(x)[/tex] only if these two numbers match.

Answer:

Proportion of total delivered on time is 70% or 7/10

Step-by-step explanation:

Here, we want to know the proportion of all the packages delivered on time.

Moving away from the percentage, let’s say the total produced package amongst the 3 is 100

So;

Service A has 60% which is 60

Service B has 30% which is 30

Service C has 10% which is 10

Now from here, we move as follows;

on time rate for service A is 80%

This means 80/100 of the 60 is delivered on time

That will be 80/100 * 60 = 48

For service B, 60% is delivered on time; Thus we have ;

60/100 * 30 = 1800/100 = 18

For service C , 40% of 10

40/100 * 10 = 4

So the total on time delivery will be;

18 + 4+ 48 = 70

So the proportion delivered on time will be 70/100 = 7/10 or 70%

Answer:

$ 13,563.20

Step-by-step explanation:

Formula for total amount accrued or gathered after interest is compounded monthly = A = P(1 + r/n)^nt

A = Amount after t years

P = Initial amount Invested = $5,000

r = Interest rate = 5% = 0.05

n = compounding frequency = Every month = 12

t = time in years = 20

A = $5000(1 + 0.05/12)^20 × 12

A = $ 13,563.20

Therefore, Peyton will have $13,563.20 in the account after 20 years.

Answer:

FV = PV (1 + )nt

PV = $5,000

r = 0.05

n = 12

t = 20

FV = 5,000 (1 + )12 · 20

= 13,563

Step-by-step explanation:

Answer:

The value is      [tex]y  =  \$ 225[/tex]

Step-by-step explanation:

From the question we are told that

   The amount charge per year is  [tex]k  =  \$ 200[/tex]

   The  number of members it will have at this amount is  [tex]n  =  50[/tex]

   The amount amount increase that will lead to the loss of a single member is   [tex]z =  \$ 5[/tex]

        Generally the total amount the club would obtain from  its members is mathematically represented as

      [tex]I  =  Amount \  due\ paid *  Number \  of members[/tex]

Now let x denote the number of member lost

Hence

      [tex]I  =  (k + zx) (n-x )[/tex]

=>    [tex]I  =  (200 + 5x) (50-x )[/tex]

=>  [tex]I  = 10000+50x-5x^2[/tex]

Thus the number of members that be removed to  give the maximum  income from dues is obtained by differentiating the above equation and equating it to zero

           [tex]\frac{dI}{dx}  =  50-10x[/tex]

=>         [tex] x   =  5[/tex]

So from  [tex]I  =  (200 + 5x) (50-x )[/tex] we have

          [tex]I  =  (200 + 5 (5)) (50-5 )[/tex]

           [tex]I  = \$ 10125 [/tex]

So the amount the club should charge is    

         [tex]y  =  \frac{10125}{50 - 5}[/tex]

         [tex]y  =  \$ 225[/tex]
