Evaluate the combination
C(y,y)

The simplified expression is approximately -1.35 × {2.54}^{2034} × {10}^{3012}.

To simplify this expression, we can first simplify the denominator by using the rule of exponents that states a^-b = 1/a^b:

2.54×{10}^{-2034} = 1/{2.54}^{2034}

Next, we can simplify the expression by multiplying the numerator and denominator by the reciprocal of the denominator:

5 × {10}^{10} / 2.54× {10}^{ - 2034 } - 1.35 *{10 }^{ - 3012 } = 5 × {10}^{10} × {2.54}^{2034} - 1.35 × {2.54}^{2034} × {10}^{3012}

Now we can factor out {2.54}^{2034} from both terms:

5 × {10}^{10} × {2.54}^{2034} - 1.35 × {2.54}^{2034} × {10}^{3012} = {2.54}^{2034} (5 × {10}^{10} - 1.35 × {10}^{3012})

We can simplify this expression further by noticing that {10}^{10} is much smaller than {10}^{3012}, so we can ignore it in the second term. This gives us:

{2.54}^{2034} (5 × {10}^{10} - 1.35 × {10}^{3012}) ≈ {2.54}^{2034} (-1.35 × {10}^{3012})

This expression is -1.35 × {2.54}^{2034} × {10}^{3012}.

The probability distribution table is formed clearly in the answer part.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The probability for all the elements in the sample space can be shown in one table known as distribution table.

Suppose X be the event of choosing a major.

Then, its probability can be given as P(X).

Here, the percent value of a given event is equivalent to their probability.

It can be represented in the form of table as,

X (Major chosen by student)                              P(X) (Probability)

    Math                                                                    3% = 0.03

   Nursing                                                                22% = 0.22

  Psychology                                                           16% = 0.16

 Criminal justice                                                      11% = 0.11

The coordinates of ABC are respectively (-2,2), (-2,3), and  (1,2).

Step-by-step explanation:

Dilation About the Origin

Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).

If we are given the dilated point, then we can find the original point by dividing by the scale factor.

Triangle ABC was dilated by a scale factor of 2 about the origin mapping it to triangle A'B'C' with vertices A'(-4,4), B'(-4,6), and C(2,4).

The coordinates of triangle ABC are:

A=(-4/2,4/2) = (-2,2)

B=(-4/2,6/2) = (-2,3)

C=(2/2,4/2) = (1,2)

The coordinates of ABC are respectively (-2,2), (-2,3), and  (1,2).

Answer:

Step-by-step explanation:

The simple short answer is because all real numbers are to be squared.

If any negative value is put into x^2, the value will become positive. That's because an even number of negatives are positive.

For example y = x * x

Let x = - 3

y = (-3)(-3)

y = 9 because there are an even number of negatives.

Notice that if break x^2 into x * x, you should see more clearly that each x is equal to - 3

The store that has a better deal on DVDs is Store A.

The amount more that Sheila will save from buying from the store with the better deal is $ 1.00.

The store with the better deal is the store that has a lower price per unit of DVDs.

Price per unit of DVD in store A:

= Cost of DVD / Number of DVDs

= 9.45 / 3

= $3.15

Price per unit of DVD in Store B :
= 12.80 / 4

= $ 3.20

Store A therefore has the better deal and the amount that Sheila will save from 20 DVDs is :

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.

Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.

This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.

He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.

Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.

Thus, looking at the provided options, option B ($850.00) would be the correct answer.

Answer: angle x is 52°

Assuming the line JK is parallel to HI. That should be given.

Step-by-step explanation:

Angle JKA is congruent to angle HIA, so both measure 62°

Add measure of AHI to JKA.

66+62= 128.

Angles of a triangle always add up to 180° so you can subtract 128 from 180 to find x.

180-128= 52°

The weight of the each pile yesterday would be 6 and 8 pounds.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given;

Yesterday the ratio of seeds in these piles was 3:4.

Let it be 3x and 4x.

If the 2 pounds of seeds is added in the bigger pile, then it become

4x + 2

He also ate 1/4 pound from the smaller pile, then

3x - 1/4

Now the quantities of seeds in those piles is in the ratio of 5:16.

So, 4x + 2 = 5x

3x - 1/4 = 16x

Solve;

So, 4x + 2 = 5x

2 = 5x - 4x

x = 2

Step-by-step explanation: Dilated triangles are never congruent, only similar (unless the dilation factor is exactly 1).

The coordinates of an image dilated about the origin are those of the pre-image multiplied by the dilation factor. For example,

The inequality is used to find the domain of the given function is

5x-5 ≥ 0

A function is a relation from a set of inputs to a set of possible outputs, where each input is related to exactly one output.

Given is function y = √(5x-5)+1, we have to find which inequality can be used to find the domain.

Since, the function is a square root function.

We know that,

The square root function is defined only for the positive values, including 0. i.e. the expression inside the square root must be greater than or equal to 0.

The expression inside the square root is (5x-5) so that must be greater than or equal to 0 which can be written as :

5x-5 ≥ 0

Similarly:

\(\implies y:20=6 : (6+x)\)
