The amount withheld in FICA Tax for Sol Berenson's weekly earnings is given as follows:

$749.7.

To calculate the amount withheld by Berenson's employer in FICA tax, we apply the proportion of the FICA tax to his total earnings.

Researching on a web search, the FICA tax rate is given as follows:

15.3% = 0.153.

As the FICA tax is a combination of the Medicare tax with the Social Security tax.

Sol Berenson's gross weekly earnings are given as follows:

$4,900.

(as stated in the problem).

The amount withheld is 15.3% of that, which is found applying the proportion, which is the multiplication of 0.153 by 4900 as follows:

Amount Withheld = 0.153 x 4900 = $749.7.

Step-by-step explanation:

Answer:

The rate of change is 4

Step-by-step explanation:

The rate of change is the slope.

The required values of functions (f₀g)(-3) is 11 and (g₀f)(6) is 23 respectively.

What is a function?

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. y and x are coupled in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x), or "f of x." In other words, the same x cannot have more than one value for f(x).

Given, f(x) = 4x - 1

g(x) = |x|

a) (f₀g)(-3) = f(g(-3)) = f(|-3|) = f(3) = 4*3-1 = 11

b) (g₀f)(6) = g(f(6)) = g(4*6-1) = g(23) = 23

The equation of the line would be y = x/3 + 1/2.

Option (B) is correct.

What is the slope-intercept form of the line?

The slope-intercept equation is used to find the general equation of a straight line using its slope and the point where it intersects the y-axis. The slope intercept form equation is given as, y = mx + b.

As we can see in the graph the line cuts the y-axis at y = 1/2

so the y-intercept of the line would be c = 1/2.

And when x=4, y = 2

So we can prepare the equation as y = x/3 + 1/2.

Hence, the equation of the line would be y = x/3 + 1/2.

The statements best describe probability as the relative likelihood that an event will occur. It is a number between 0 and 1 inclusive.

Probability

A mathematical tool used to examine unpredictability is probability. It discusses the likelihood that an event will occur. For instance, you might not get two heads and two tails if you flip a fair coin four times. But if you flip the same coin 4,000 times, you'll get results that are almost evenly split between heads and tails. The theoretically predicted chance of heads in any given toss is 12, or.5. There is a predictable pattern of results when there are numerous repetitions, even though the results of a few repetitions are unknown. One of the authors tossed a coin 2,000 times after reading about the English statistician Karl Pearson, who threw a coin 24,000 times and got 12,012 heads. The outcome was 996 heads. The expected chance of 5 is quite near to being reached by the fraction of 9962,000, which is equivalent to 498.

Answer:

2y + 19 over 7

Step-by-step explanation:

Steps Using Substitution

7x−3у=−12−2x+3y=−3

Consider the first equation. Add 2x to both sides.

7x−3у+2x=−12+3y

Combine 7x and 2x to get 9x.

9x−3у=−12+3y

Subtract 3y from both sides.

9x−3у−3y=−12

Add 3у to both sides.

9x−3y=−12+3у

Consider the second equation. Add 12 to both sides.

−2x+3y=−3+12

Add −3 and 12 to get 9.

−2x+3y=9

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

9x−3y=3у−12,−2x+3y=9

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

9x−3y=3у−12

Add 3y to both sides of the equation.

9x=3y+3у−12

Divide both sides by 9.

x=1 over 9​(3y+3у−12)

Multiply 91​ times −12+3y+3у.

x=1 over 3​y+3у−4​

Substitute 3−4+y+у​ for x in the other equation, −2x+3y=9.

−2(31​y+3у−4​)+3y=9

Multiply −2 times 3−4+y+у​.

−32​y+38−2у​+3y=9

Add −2y over 3​ to 3y.

7 over 3​y+38−2у​=9

Subtract 8−2у​ over 3 from both sides of the equation.

37​y=32у+19​

Divide both sides of the equation by 37​, which is the same as multiplying both sides by the reciprocal of the fraction.

y=72у+19​

Substitute 719+2у​ for y in x=31​y+3у−4​. Because the resulting equation contains only one variable, you can solve for x directly.

x=31​×(72у+19​)+3у−4​

Multiply 31​ times 719+2у​.

x=212у+19​+3у−4​

Add 3−4+у​ to 2119+2у​.

x=73у−3​

is now solved.

y=72у+19​

Step-by-step explanation:

You want the value of x that makes the perimeter of a rectangle be 38 cm when sides are x and (2x+7). And you want the largest angle in the quadrilateral with angles x+17, 2x+15, 2x+30, and 4x+19.

The perimeter of a rectangle is given by the formula ...

  P = 2(L +W)

Substituting the given values, we have ...

  38 = 2((2x+7) +x)

Dividing by 2 gives ...

  19 = 3x +7

  12 = 3x . . . . . . . subtract 7

  4 = x . . . . . . . divide by 3

The value of x is 4 cm.

The sum of the angles of a quadrilateral is 360°. This tells us ...

  360 = (x +17) +(2x +15) +(2x +30) +(4x +19)

  360 = 9x +81 . . . . . . . collect terms

⭐Properties of a kite

(∠1) + (∠2) + (∠3) + (∠4) = 360°

(2x + 15) + (2x+30) + (4x+19) + (x+17) = 360

9x + 81 = 360 . . . . . . . add like terms

9x = 279 . . . . . . . . . . . subtract 81 from LHS and RHS

x = 31 . . . . . . . . . . . . . . divide LHS and RHS by 9

When two continental plates collide along a convergent plate boundary from a mountain because both plates share the same mass and thickness.

Due to the weight and thickness of the two continental plates being equal during the collision, no plate will sink into the other, which causes mountain development.

Rocks are pushed up to a mountain range as a result of their collision, as opposed to crumpling and folding. A taller mountain will be produced as plate tectonics continue.

The level of collision affects the notion of plate tectonics; continuing collision results in a higher mountain.

Consequently, a mountain is the result of a tectonic plate collision along a convergent border.
