Answer:

x = 1/2

y = 7/2

Step-by-step explanation:

Mate, you almost solved the question there by yourself.

You were at the last step.

-6x + 3 = 0

Add 6x on both sides,

-6x + 3 + 6x = 6x

3 = 6x

Divide 6 on both sides,

3/6 = 6/6 x

1/2 = x

So, y = 7x

y = 7/2

The trigonometrical ratios of the triangle are:

sin∠X = x/z

cos∠X = y/z

tan∠X = x/y

sin∠Y = y/z

cos∠Y = x/z

tan∠Y = y/x

We will use trigonometrical ratios to solve this problem. Below are the definitions of the trigonometrical ratios:

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

tan = opposite/adjacent or tan = sin/cos

The opposite is the side the angle of consideration is facing

The hypotenuse is the side the right angle  is facing

The adjacent is the side left after determining the opposite and hypotenuse

Thus, we have the following trigonometric ratios in the triangle:

sin∠X = x/z

cos∠X = y/z

tan∠X = x/y

sin∠Y = y/z

cos∠Y = x/z

tan∠Y = y/x

The 3rd-degree polynomial has at least one or three real roots.

Yes, a third degree polynomial can have all real roots. This is because a third degree polynomial has at least one real root, as it is the lowest degree polynomial that can have an imaginary root. The other two roots can be real or imaginary, depending on the coefficients of the polynomial. If the discriminant of the polynomial is greater than or equal to zero, the polynomial will have all real roots. In a cubic polynomial, only one or three real roots are present. Polynomials having odd degrees have at least one real root. A cubic equation's graph must at least once cross the x-axis, giving you at least one real root. Only a quadratic polynomial has two real roots. Quadratic polynomials are those having a degree of two. Polynomials can be represented on the graph, on that basis we can determine whether the roots are real or not.

The rate of change of the hypotenuse is 9.5 inches per second.

The rate of change of the hypotenuse of a right triangle can be calculated using the Pythagorean theorem. The theorem states that for a right triangle with sides of length a, b, and c (where c is the hypotenuse), a2 + b2 = c2.

In this case, we know that the two legs are 3 inches and 4 inches, and that the short leg is increasing by 7 in/sec and the long leg is growing at 9 in/sec.

Using the Pythagorean theorem, we can calculate the rate of change of the hypotenuse. We can set up the equation as follows: c2 = 32 + 42, where c is the hypotenuse. Solving for c, we get: c = √(32 + 42).

To calculate the rate of change of the hypotenuse, we need to take the derivative of the equation. Taking the derivative of the equation, we get: c' = (7/2) * (3/c) + (9/2) * (4/c).

Plugging in our values, we get: c' = (7/2) * (3/5) + (9/2) * (4/5). Simplifying, we get: c' = 9.5 in/sec.

Therefore, the rate of change of the hypotenuse is 9.5 inches per second.

Answer: 4.2

Step-by-step explanation: First, you'd need to re-arrange the decimals so, you can get 4.65.........

Then, you round up to get about 4.7

Another way is to round up the decimals, so your new equation:

[tex]\frac{21}{5}[/tex]

Then, you'd divide to get 4.2. This way is more of an estimate than the 1st way; the 1st way is an exact answer [rounded] I hope this helped.

Answer:

  4.64

Step-by-step explanation:

You want an estimate of the quotient 21.4/4.6.

Multiplication and division by 5 are simplified by the relation ...

  5 = 10/2

Here, the denominator is about 5, so the quotient is about ...

  21.4 × 2/10 = 42.8/10 = 4.28 ≈ 4.3 . . . . . a first estimate; known to be low

We notice that 4.6 is 0.4 less than 5, which is 0.8/10 = 0.08, or 8% less. That means the actual quotient will be on the order of 8% more than 4.3.

A closer estimate would be ...

  4.3 + 0.08 · 4.3 = 4.3 +0.344 ≈ 4.64

An estimate of the quotient is 4.64.

__

Additional comment

To compute our "error correction," we rounded 4.28 up to 4.3, about 2 parts in 400, making that number (4.3) be about 0.5% high. The estimate of 1/0.92 ≈ 1.08 turns out to be about 0.7% low. This means an even better estimate would add 0.2%, or about 0.009, to the estimate we have, making it about 4.653. These second-order corrections are also slightly off. The actual quotient rounds to 4.652.

Doubling a number is so easy that we elected to keep all of the digits of the numerator when we did the division by 5. This gave a more satisfying 4.3 instead of 4 as the first estimate.

On solving the provided question, we can say that the probability of guessing the sequence 2^99 possible combinations.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true.

As soon as you realize there are more heads than tails, you realize you require at least 50 of them, and you ask 100 people to select 50 locations for them to go.

Considering that you have 250 options for the remaining coins, there are a total of (100 pick 50) + 250 combinations that are feasible.

There are 299 potential options if you simply inquire as to whether the first coin will land on heads.

Asking whether there are more heads than tails is preferable because, according to Wolfram Alpha, 299 is larger than (100 pick 50) + 250.

Since X, Y, and Z are independent random variables, the probability of one event occurring has no bearing on the likelihood of the other events. In this instance, the probabilities of X, Y, and Z are 30%, 40%, and 20%, respectively.

We must take into account the possibility that both events could occur simultaneously when determining the likelihood that either X or Y will occur. The occurrences where both X and Y occur would be doubly counted if we just added the probabilities of X and Y. To circumvent this, we employ the following formula for the chance of two events occurring together:

P(X or Y) = P(X) + P(Y) - P (X and Y)

This formula takes into account the fact that we must deduct the probability of X and Y's intersection (i.e., the likelihood that they both occur) from the total of each variable's individual probabilities.

Given that X and Y are independent events, P(X and Y) = P(X) * P(Y) = 0.3 * 0.4 = 0.12 is known.

P(X or Y) is therefore equal to P(X) + P(Y) - P(X and Y) = 0.3 + 0.4 - 0.12 = 0.68 = 68%

Using the formula of probability without replacement, the probability of selecting a heart first is 13 / 52 and a diamond second is 13 / 51

Probability without replacement refers to the likelihood of a specific event occurring when items are removed from a set or collection as they are selected. It differs from probability with replacement, where the items are replaced after each selection and the set remains unchanged.

To calculate probability without replacement, we use the formula:

P(Event) = Number of favorable outcomes / Number of possible outcomes

Where the number of possible outcomes is the total number of items in the set, and the number of favorable outcomes is the number of items that satisfy the conditions of the event.

Your adjusted gross income (AGI) consists of the total amount of income and earnings you made for the tax year minus certain adjustments to income. The dollar amount on line 10 is calculated by subtracting the standard deduction and personal exemptions from the taxable income.

Line 10 on the 1040EZ form is labeled "Taxable income" and is used to calculate the amount of taxes owed to the IRS. Line 11, labeled "Tax," is used to enter the amount of taxes already paid, either through withholding or estimated payments.

If $4184 is on line 11 and the taxpayer will neither receive a refund nor owe the IRS, that means that the amount of taxes already paid, $4184, is equal to the amount of taxes owed, which is calculated on line 10.

Therefore, the dollar amount on line 10 would also be $4184. This indicates that the taxpayer's taxable income and their taxes already paid are equal, resulting in no additional taxes owed or refund due.

Even polynomial functions have terms that are all even powers of the variable.

Odd functions are symmetrical about the origin. A function is odd if ...

  f(x) = -f(-x)

Odd polynomial functions have terms that are all odd powers of the variable.

The graphed polynomial function has a non-zero added constant (the y-intercept value), so has both even and odd terms. It is neither even nor odd.

The graph is neither symmetrical about the y-axis, nor symmetrical about the origin.
