The eligible amount of work-related daycare expenses will be $2600

Married filing jointly is a filing status for married couples, allowing them to file joint tax returns. When filing taxes under married filing jointly status, a married couple can record their respective incomes, deductions, credits, and exemptions on the same tax return.

Given here wages of the cliff are $16,228 and if the deb is  $2,600

now the mfj is 35% hence cliffs credit is 35% ×  $16,228 = $5679.8

and daycare yearly expenses are = $250×12

                                                        = $3000

but deb's income is $2600 and thus credit cannot exceed deb's wages therefore the revised credit would be $2600

Hence, the eligible amount of work-related daycare expenses will be  $2600

The statement given is true. When approximating the area below a curve, using midpoint rectangles always produces the best approximation.

A good way to estimate areas with rectangles is to make each rectangle cross the curve at the midpoint of that rectangle's top side. Midpoints always the best approximate for the area under the curve using a finite number of rectangles.

The midpoint rule, also known as the rectangle method or mid-ordinate rule, is used to estimate the area under a simple curve. There are other methods to estimate the area, such as the left rectangle or right rectangle sum, but the midpoint rule gives the better approximate compared to the two methods.

The possible equation of the parabola is f(x) = (x - 1)² - 5

From the question, we have the following parameters that can be used in our computation:

Vertex = (1, -5)

Rewrite the vertex as follows

So, we have the following representation

(h, k) = (1, -5)

A quadratic function can be represented as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

Substitute the known values in the above equation, so, we have the following representation

f(x) = a(x - 1)² - 5

Set a = 1

f(x) = (x - 1)² - 5

Hence, the function is (d) f(x) = (x - 1)² - 5

Answer:

Drink: $5

Candy : $3.75

Step-by-step explanation:

Let d = the cost of a drink

Let c = the cost of a candy

9d + 4c = 60

10d + 2c = 57.50 ⇒ Mult. by -2 ⇒ -20d -4c = -115  Add this to the first equation

-20d  - 4c = -115

9d + 4c = 60

-11d = -55  Divide both sides by -11

d = 5

A drink costs $5.00.

Plug in 5 for d in either of the two equations to solve for c

9d + 4c = 60

9(5) + 4x = 60

45 + 4c = 60  Subtract 45 from both sides

4c = 15  Divide both sides by 4

x = 3.75

A candy costs $3.75

Answer/Step-by-step explanation:

Since the axes are labelled and there are nice points marked on the line, you can practically SEE the slope here without any calculating, just by counting. Start with a point and find the directions to the next point. To get from one point to the next, go UP2 and OVER3.

"UP2 and OVER3" is the slope 2/3.  Double check that you get a slope that is positive because the line is going up to the right, it should have positive slope.

If the teacher is insisting that you use the slope formula, then name two of the points, such as (0, 4) and (3, 6). First subtract the y's, 6 - 4 is 2, put that on top of a fraction. Then subtract the x's, 3 - 0 is 3, put that on the bottom of a fraction. You get 2/3 again. Doesn't matter what points you use, since they are all on the same line it will come out the same.

What is null hypothesis?

A null hypothesis is an educated guess or a prediction of the expected outcome of a particular experiment. It is a statement that assumes there is no difference between two groups or no association between two variables. The null hypothesis is often the opposite of the alternative hypothesis, which is the prediction that the researcher is hoping to prove.

Example 1: In a study of the effectiveness of a new drug for treating depression, the null hypothesis would be that the drug has no effect on depression levels.

Example 2: In a study of the association between smoking and lung cancer, the null hypothesis would be that there is no association between the two variables.

1. Number  of generators of  Z*4969 = 1584

2. Probability of a randomly chosen element a Z*_969 being a generator      = [tex]\frac{1584}{4968}[/tex]

3. 1001 is the smallest generator

      ∅(n) = n [tex](1 - \frac{1}{p_{1} } )(1 - \frac{1}{p_{2} } ).........(1 - \frac{1}{p_{n} } )[/tex]

1. Every relative prime of 4968 offers a generation if a is the generation of Z.

4968 = 4 × 1242

         = 4 × 3 × 414

         = 4 × 3 × 2 ×207

         = 4 × 3 × 2× 3× 69

         [tex]= 2^{3} * 3^{3} * 23[/tex]

Number of generators ∅ (4968) = 4968[tex](1 - \frac{1}{2} )(1 - \frac{1}{3} )(1 - \frac{1}{23} )[/tex]

Number  of generators of  Z*4969 = 1584

2. When a Z*4969 value is set, it becomes a generation and belongs to one of the 1584 elements.

The probability that a element is selected from Z*4968 becomes a generation is

=  favorable elememt / total element

= 0.3188

3. To find the smallest generator a Z*_969 with a > 1000.

      a > 1000

Every relative prime of 4968 gives a generation of Z*4969

G C D (1001   4968) = 1

Hence, 1001 is the smallest generator

In triangle WUT, the length of the side adjacent to the angle of x has a length of 13.5 cm.

Reminding the two features of similar triangles, namely congruent angle measures and proportional side lengths, the measure of angle x is given as follows:

[tex]H_a[/tex]: The mean time it takes for the new technique to receive an advanced driving license is greater than 90 hours, i.e. [tex]\mu > 90[/tex].

Answer:

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 1.5/100

r = 0.015 per year,

Then, solve the equation for P

P = I / ((1 + r/n)nt - 1)

P = 3150 / ((1 + 0.015/2)(2)(5) - 1)

P = 3150 / ((1 + 0.0075)(10) - 1)

P = $40,601.92

The principal investment required to get a total interest of $3150 from compound interest at a rate of 1.5% per year compounded 2 times per year over 5 years is $40,601.92.

[tex]\implies x+y=350[/tex]

If the piggy bank contains pennies and nickels worth $11.90:

[tex]\implies 0.01x+0.05y=11.90[/tex]

Rearrange the first equation to make y the subject:

[tex]\implies y=350-x[/tex]

Substitute the expression for y into the second equation and solve for x:

[tex]\implies 0.01x+0.05(350-x)=11.90[/tex]

[tex]\implies 0.01x+17.5-0.05x=11.90[/tex]

In the given question, there are a total of 64 students in a film-making club and a yearbook club.

The film-making club has 14 more students than the yearbook club.

a. We have to write a system of linear equations that represents this situation.

Let x represent the number of students in the film-making club

Let y represent the number of students in the yearbook club.

As given that the film-making club has 14 more students than the yearbook club.

So x = y+14

Total students are 64.

So x+y = 64

System of equations:

x= y+14

x+y = 64

b. Now we have to find how many students are in the film-making club and the yearbook club.

The system of equations are;

x= y+14...................(1)

x+y = 64...................(2)

Now putting the value of x in equation 2.

y+14+y = 64

2y+14 = 64

Subtract 14 on both side, we get;

2y = 50

Divide by 2 on both side, we get;

y = 25

Now putting the value of y in equation 1.
