Molly's gross income is $360, and after subtracting her total deductions ($66.04), her net income is $293.96. This demonstrates the difference between gross and net income.

To find Molly's net income, we will first need to calculate her gross earnings, and then subtract her deductions. Molly's gross earnings are her hourly wage multiplied by the number of hours she worked, so: $8/hr * 45 hours = $360.

Next, we add up Molly's deductions: $38.50 (federal tax) + $22.32 (Social Security) + $5.22 (Medicare) = $66.04.

Finally, to determine Molly's net income, we subtract her total deductions from her gross earnings: $360 - $66.04 = $293.96.

This example illustrates the concept of gross income versus net income. Gross income is the total amount earned before deductions, and net income is the amount left after deductions have been subtracted, which is the exact amount the employee receives in their paycheck.

38 cannot be the perimeter of the triangle.

The sum of any two sides of a triangle is greater than or equal to the third side.

Given:

Two sides are 12 and 7.

Using Triangle Inequality Theorem, we have

In ΔABC,

So,

12 + 7 > C

19 > C

C < 19

So, the third side should be less than 19.

Let us take maximum possible values,

C  =18.999

Then, perimeter will be,

12 + 7 + 18.999 = 37.999

Hence, 38 cannot be the perimeter.

The critical value zα/2 that corresponds to a given confidence level can be found by subtracting the confidence level from 1, dividing by 2, and looking up this value in the Z-table. For a 90% confidence level, the corresponding zα/2 is approximately 1.645.

To find the associated critical value zα/2 for a given confidence level, you would first subtract the confidence level from 1, then divide by 2. This will give you α/2. You would then look up this value in the Z-table to find the corresponding critical value of z. Now, let's consider an example.

Assume a confidence level of 90%. We subtract this from 1, which gives us 0.10, and then dividing by 2 gives us 0.05. Now we look up 0.05 in the Z-table, and find that the corresponding value of z is approximately 1.645. Therefore, the critical value zα/2 that corresponds to a 90% confidence level is approximately 1.645.

Answer:

2.95 x + 39.95 (12)

Hope this helps!!

The yearly cost for a student's movie rentals with a monthly subscription fee and a per-movie fee is expressed as $479.40 + $2.95x, where x is the number of movies rented.

The yearly cost for x movie rentals from an on-demand movie company that charges a monthly fee and a per-movie fee can be represented by an algebraic expression. To find this expression, we need to account for both the monthly fee and the cost per movie.

The monthly fee is $39.95, so over one year, this fee would be 12 times $39.95.

For each movie rented, there is an additional charge of $2.95. If x movies are rented over a year, this cost is x times $2.95.

Combining these two costs gives us the total yearly cost:

Yearly Cost = (12 \(\times\) $39.95) + ($2.95 \(\times\) x)

This can be simplified to:

Yearly Cost = $479.40 + $2.95x

Answer:

23500

Step-by-step explanation:

We are given that

Number of species of mammals on earth=approximately 45 hundred=4500

Number of species of fish=[tex]2.8\times 10^4=2.8\times 10000=28000[/tex]

We have to find the difference between the number of species of mammals and fish.

In order to find the difference in the number of species we will subtract number of species mammals from the number  of  species of fish.

Difference=28000-4500=23500

Hence, the difference between the number of species of mammals and fish=23500

Answer:

23,500

Step-by-step explanation:

45 hundred = 45 × 100 = 4,500

2.8 × 10^4 = 28,000

28,000 - 4,500 = 23,500

Answer:

coresponding angles buddy

Step-by-step explanation:

Option B is correct. The measure of m<RSP  is 49 degrees

From the diagram shown

3x + 2x + 1 + 8y - 13 = 180

5x + 8y - 12 = 180

5x + 8y = 180  + 12

5x + 8y = 192 ................. 1

Also, since PQ is parallel to PS, hence;

5y +14 = 8y - 13 (alternate interior angle)

5y - 8y = -13 - 14

-3y = -27

y = 27/3

y = 9

Substitute y = 9 into equation 1

5x + 8y = 192

5x + 8(9) = 192

5x + 72 = 192

5x = 192 - 72

5x = 120

x = 120/5

x = 24

Get the measure of <RSP

m<RSP = 2x + 1

m<RSP = 2(24) + 1

m<RSP = 48 + 1

m<RSP  = 49degrees

Hence the measure of m<RSP  is 49 degrees

The degree of the polynomial function f(x) is 4.

The roots of the equation f(x)=0 are [tex]−6 , −2 , 1,[/tex] and 3.

We are given with four roots. they are the x intercepts

x intercepts are [tex]−6 , −2 , 1,[/tex] and 3

The polynomial has degree 4, the polynomial goes up on both sides

We look at the graph that has x intercepts [tex]−6 , −2 , 1,[/tex] and 3 and both ends of the graph goes up

option B is correct

The graph that could be the graph of f(x) is;

The second graph which is the one at the top right

We are told that;

Degree of polynomial f(x) = 4; This means it has 4 roots

Roots of polynomial = -6, -2, -1 and 3

The roots of a polynomial simply means the values of x at which the function f(x) is equal to zero. This simply means the x- intercept is the root.

Thus, the x-intercept of the correct graph should be at;

x = -6; x = -2 ; x = -1 and x = 3

Looking at the given graphs, the only one that has its' x-intercepts at x = -6; x = -2 ; x = -1 and x = 3 is the second graph at the top right.

36 - 8i is correct. Using FOIL we get 30 - 8i - 6i2, but since i2 = -1, we get 30 - 8i - 6(-1), which is 30 - 8i + 6 = 36 - 8i.

The completely factored form of expression 16x⁴ - 81 is  (4x² - 9)(4x² + 9).

To factor the expression 16x⁴ - 81 completely, let's first factor each term:

16x⁴ can be written as (4x²)² since (4x²)²= 16x⁴.

81 can be written as 9² since 9² = 81.

Now, we can rewrite the expression:

16x⁴ - 81 = (4x²)² - 9²

Using the formula a² - b² = (a - b)(a + b).

we can apply it twice to factor the expression further:

(4x² - 9)(4x² + 9)

Therefore, the completely factored form of 16x⁴ - 81 is (4x² - 9)(4x² + 9).

The equation of the line that passes through the point (22,12) and has a slope of 4 is; y = 4x - 76

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

Where x₁ - x coordinate and y₁ - y coordinate

Point (22,12)

Then Slope m =4

Now Write the equation as

y - 12 = 4(x - 22)

y = 4x - 76

Hence, the standard form of the line is; y = 4x - 76
