The probability of getting a number greater than 1 is 5/6

What is the formula of Probability?

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event happen P(E) = Number of favourable outcomes / Total number of outcomes.

The possible outcomes when a die thrown is {1, 2, 3, 4, 5, 6}. Therefore, the number of possible outcomes of a die is 6.

Now, the numbers greater than 1 between 1 to 6 are P{2, 3, 4, 5, 6} then the number of favourable outcome is 5.

Therefore, probability P of getting a number greater than 1 is:

P = 5/6

Hence, the probability of getting a number greater than 1 is 5/6

​According to the given data  4 a+6 b=6 and -2 a+b=-7 the value of a = 3.

The algebraic method for solving simultaneous linear equations is the substitution method. The value of one variable between one equation is exchanged in the second equation, as the name implies.

First, we will remove bb from the second equation and then substitute it in the first equation:

b= −7 + 2a

After replacing in the first equation:

(substitute)

4a+6(−7+2a) = 6

(multiply)

4a−42+12a = 6

(combine like term)

16a = 48

(divide both side by 16)

a = 3

​According to the given data  4 a+6 b=6 and -2 a+b=-7 the value of a = 3.

If Δ ABC , medians AR, BS , and CQ then the value of AP = 2/3 AR,

BP = 2/3 BS, and CP = 2/3 CQ.

The triangle's centroid is the point where the three medians intersect. According to the centroid theorem, the centroid is 23 times the distance from each vertex to the midpoint of the opposite side.

Given: ΔABC, medians AR, BS, and CQ

AP = 2/3 AR, BP = 2/3 BS, and  CP = 2/3 CQ.

Slope of [tex]$\overline{A R}=\frac{3 c}{3 b+3 a}=\frac{c}{b+a}$[/tex]

Slope of [tex]$\overline{B S}=\frac{6 c}{6 b-3 a}=\frac{2 c}{2 b-a}$[/tex]

Slope of [tex]$\overline{C Q}=\frac{3 c}{3 b-6 a}=\frac{c}{b-2 a}$[/tex]

AR contained in the line [tex]$y=\left(\frac{c}{b+a}\right) x[/tex], BS contained in the line [tex]$y=\left(\frac{2 c}{2 b+a}\right)(x-3 a)[/tex], CQ contained in the line [tex]$y=\left(\frac{c}{b-2 a}\right)(x-6 a)$[/tex]

To find the coordinates of P, find the intersection point of two medians, BS and CQ.

[tex]$y=\left(\frac{2 c}{2 b-a}\right)(x-3 a) \text[/tex] and [tex]$y=\left(\frac{c}{b-2 a}\right)(x-6 a)[/tex]

[tex]$\frac{2 c}{2 b-a}(x-3 a) &=\frac{c}{b-2 a}(x-6 a) \\[/tex]

simplifying the above equation, we get

[tex]2 c(x-3 a)(b-2 a) &=c(x-6 a)(2 b-a) \\[/tex]

[tex]2 c\left(b x-2 a x-3 a b+6 a^2\right) &=c\left(2 b x-a x-12 a b+6 a^2\right)[/tex]

[tex]2 b c x-4 a c x-6 a b c+12 a^2 c &=2 b c x-a c x-12 a b c+6 a^2 c \\[/tex]

[tex]-3 a c x &=-6 a b c-6 a^2 c \\[/tex]

x = 2b + 2a

To find the value of y,

[tex]$y=\frac{2 c}{2 b-a}(x-3 a)[/tex]

simplifying the above equation, we get

[tex]$=\frac{2 c}{2 b-a}(2 b+2 a-3 a)[/tex]

[tex]$=\frac{2 c(2 b-a)}{2 b-a}=2 c$$[/tex]

So the coordinates of P are (2b + 2a, 2c).

Now, show that P is on AR.

[tex]$&y=\left(\frac{c}{b+a}\right)(2 b+2 a)=\frac{2 c(b+a)}{b+a}=2 c[/tex]

Thus, the three medians intersect at the same point.

All About the FICA Tax

If you earn a wage or a salary, you’re likely subject to Federal Insurance Contributions Act taxes. Not to be confused with the federal income tax, FICA taxes fund the Social Security and Medicare programs. Also known as payroll taxes, FICA taxes are automatically deducted from your paycheck. Your company sends the money, along with its match (an additional 7.65% of your pay), to the government. In this article we’ll discuss what FICA taxes are, how they’re applied and who’s responsible for paying them.

Planning your finances goes beyond just taxes. Find a local financial advisor today.

FICA Taxes: The Basics

Every payday, a portion of your check is withheld by your employer. That money goes to the government in the form of payroll taxes. There are several different types of payroll taxes, including unemployment taxes, income taxes and FICA taxes. Two types of taxes fall under the category of FICA taxes: Medicare taxes and Social Security taxes.

Paying FICA taxes is mandatory for most employees and employers under the Federal Insurance Contributions Act. The funds are used to pay for both Social Security and Medicare.

If you own a business, you’re responsible for paying Social Security and Medicare taxes, too. For self-employed workers, they’re referred to as SECA taxes (or self-employment taxes) based on regulations included in the Self-Employed Contributions Act.

A wage base limit applies to employees who pay Social Security taxes. This means that gross income above a certain threshold is exempt from this tax. The wage limit changes almost every year based on inflation. In 2021, it was $142,800. For 2022, the limit rose to $147,000. This income ceiling is also the maximum amount of money that’s considered when calculating the size of Social Security benefits.

Medicare taxes, on the other hand, don’t have a wage limit. But there’s an Additional Medicare Tax that high-income individuals must pay. That has been the case since January 1, 2013.

The Additional Medicare Tax rate is 0.90% and it applies to employees’ (and self-employed workers’) wages, salaries and tips. So any part of your income that exceeds a certain amount gets taxed for Medicare at a total rate of 2.35% (1.45% + 0.90%). That income ceiling for 2021 and 2022 is $200,000 for single filers, qualifying widows and anyone with the head of household filing status; $250,000 for married couples filing joint tax returns and $125,000 for couples filing separate tax returns. You can calculate how much you owe using Form 8959.

The solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.

According to the given question.

We have an equation 5x/4 - 3/x= 1/4.

As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.

Therefore, the solution of the equation 5x/4 - 3/x= 1/4 for x is given by

5x/4 - 3/x= 1/4

⇒ ( 5x^2 -12) /4x  = 1/4

⇒ 5x^2 - 12   = (1/4)4x                 (multiplying both the sides by 4x)

⇒ 5x^2 - 12 = x

⇒ 5x^2 - x -12 = 0

⇒ x = [tex]\frac{1\pm\sqrt{1+240} }{10}[/tex]

⇒ x = (1+√241)/10 or (1 -√241)/10

Hence, the solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.
