Answer:

$29.14

$86.68

Step-by-step explanation:

$30 before tax

Discount: 20%

100% - 20% = 80% = 0.8

0.8 * $30 = $24 after discount

Tax: 6.4%

100% + 6.4% = 106.4% = 1.064

1.604 * $24 = 25.54 after tax and discount

Tip: 15% = 0.15

0.15 * $24 = $3.60

Total = $25.54 + $3.60 = $29.14

$75 before tax

10% discount

100% - 10% = 90%

90% of $75 = 0.9 * $75 = $67.50 after discount

Tax: 7%

100% + 7% = 107% = 1.07

1.07 * $67.5 = $72.23 after discount and tax

Tip: 20% = 0.2

0.2 * $67.50 = $13.50

Total = $72.23 + $13.50 = $85.73

Answer:

15%

Step-by-step explanation:

when 18000 is 100%, 10% is 1800. So to make 15300 we need 8.5 1800s. So 85% of 18000 is 15300 so the rest is 15%. The answer is 15%

Answer:

15%

Step-by-step explanation:

[ (18,000-15,300) / 18,000 ] x 100

= (27,00 / 18,000) x 100

= 0.15 x 100

= 15%

The mean of the population is

4

.

The mean of the sample is

3.25

.

The difference between  the mean of the sample and the mean of the population is

0.75

.

Step-by-step explanation:

Just did it

The difference between the mean of the sample and the mean of the population is equal to 0.75

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

We are given the

2 5 10 N 4 1 5 3

The mean of the population is;

0 + 1 + 4 + 3 / 4 =  4.

The mean of the sample is;

4 + 1 + 5 + 3 / 4 =  3.25

The difference between the mean of the sample and the mean of the population is;

4 - 0.35 =  0.75

Answer:

probability of blue =5/20=1/4

Step-by-step explanation:

probability of yellow=4/20=1/5

Probability of selecting a blue colour then a yellow colour is, 1/19.

Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.

Given, A bowl containing 4 yellow, 6 orange, 3 green, 5 blue, 2 brown colors.

Let P(A) be the probability of selecting a blue colour.

∴ P(A) = N(B)/N(S).

P(A) = 5/20.

P(A) = 1/4.

Let P(B) be the probability selecting a yellow colour is = 4/19.

As we replacement is not allowed.

∴ Probability of selecting a blue colour then a yellow colour is,

= P(B)×P(A).

= 4/19×1/4.

= 1/19.

Answer:

(5,4)

Step-by-step explanation:

multiply each equation by the value that makes the coefficients of x opposite

(-1) · (4x + 6y) = (-1) · 44

4x + 2y = 28

simplify

-4x - 6y = -44

4x + 2y = 28

add the two equations together to eliminate x from the system

      -4x - 6y = -44

+      4x + 2y = 28

              -4y = -16

divide each term by -4

y = 4

substitute the value for y into one of the original equations, then solve for x

-4x - 6y = -44

-4x - 6(4) = -44

-4x - 24 = -44

     + 24   + 24

-4x = -20

divide by -4

x = 5

so, since x = 5 and y = 4 ....

the solution to the independent system of equations can be represented as a point.

Answer:

22.75 hours per week

Step-by-step explanation:

We can see from the question that the target amount of money is $190.00 per week.

If Lauren Rodriguez earns $8.35 in one hour

then $190.00 will be earned in x hours

8.35x = 190.00

x = 190.00/8.35

x = 22.75 hours per week

Candy bars: $13

Step-by-step explanation:

$3 magazine + $13 total of candy bars = $19

Answer:

here is a simple version

lets make A equal the exponent so (A=^2 or 3 or whatever)

the exponent will be the amount of times you want to repeat the process.

Now lets make x = the first array, so x=3

and lets make y = the second array, y=7

now a simple equation would be (3x)(7y)^A or for this you could say

(3x)(7y)^6

Answer:

Part 1)

[tex]f(g(x))=10x^3+16[/tex]

Part 2)

The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=2x^2+16[/tex]

Which represents the amount of money Raul earns per ticket and:

[tex]g(x)=\sqrt{5x^3}[/tex]

Which represents the number of tickets Raul sells per hour.

Part 1)

We want to find f(g(x)).

So, we substitute g(x) for f(x). This yields:

[tex]f(g(x))=2(\sqrt{5x^3})^2+16[/tex]

This can be expanded a simplified as such:

[tex]f(g(x))=2((\sqrt{5})^2(\sqrt{x^3})^2)+16=10x^3+16[/tex]

Part 2)

Recall that f(x) outputs the amount of money Raul earns per ticket.

And g(x) inputs the amount of hours Raul works.

When we composed f(g(x)), the input and output stayed the same.

So, f(g(x)) represents the amount of money Raul earns per ticket (output of f(x)) given the amount of hours Raul works (input of g(x)).

Answer:

The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works
