The net pay for Lonnie Flanagan is $1065.

From the information, Lonnie weekly gross pay is $1250 and each week she has $64.37 in deductions, plus state tax of 2% of her gross pay, social security taxes of 6.2%, and Medicare taxes of 1.45%.

Her net pay will be:

= Gross pay - Deduction - Tax - Social security - Medicare

= $1250 - $64.37 - (2% × $1250) - (6.2% × $1250) - (1.45% × $1250)

= $1250 - $64.37 - $25 - $$77.50 - $18.125

= $1065

Depreciation is the gross reduction in the book value of an asset due to regular use or wear and tear.

A capital gain occurs when Garcia Co. receives an amount in excess of the book value of the equipment.

If Garcia Co. receives an amount equal to the book value of the equipment, no profit or loss will result from the disposal.

If Garcia Co. receives an amount below the book value of the equipment, it will experience a capital loss.

In the given question cost of equipment is $81,600 with accumulated depreciation of $43,200 so that the book value will be

$81,600 - $43,200 = $38,400.

Now (1) $50,600 cash implies that $50,600 - $38,400 = $12,200

Hence gets gain of $12,200.

For (2) $38,400 cash implies that $38,400 - $38,400 = $0

Hence No profit no loss.

For(3) $33,300 cash implies that $33,300 - $38,400 = - $5,100

Answer:7937

Step-by-step explanation:7596

the maximum height is 254 feet.

Answer:

a)  0.5 seconds and 3.5 seconds.

b)  5.98 seconds (2 d.p.)

c)  No.

d)  254 feet at 2 seconds.

Step-by-step explanation:

Given equation:

[tex]h=-16t^2+64t+190, \quad t \geq 0[/tex]

where:

To calculate when the object will be 218 feet above the ground, substitute h = 218 into the equation and solve for t:

[tex]\begin{aligned}\implies -16t^2+64t+190 & = 218\\-16t^2+64t+190-218& = 0\\-16t^2+64t-28 & = 0\\-4(4t^2-16t+7) & = 0\\4t^2-16t+7 & = 0\\4t^2-14t-2t+7 &=0\\2t(2t-7)-1(2t-7)&=0\\(2t-1)(2t-7)&=0\\\implies 2t-1&=0\implies t=\dfrac{1}{2}\\\implies 2t-7&=0 \implies t=\dfrac{7}{2}\end{aligned}[/tex]

Therefore, the object will be 218 feet about the ground at 0.5 seconds and 3.5 seconds.

The object strikes the ground when h is zero. Therefore, substitute h = 0 into the equation and solve for t:

[tex]\begin{aligned}\implies -16t^2+64t+190 & = 0\\-2(8t^2-32t-95) & = 0\\8t^2-32t-95 & = 0\end{aligned}[/tex]

Use the quadratic formula to solve for t:

[tex]\implies t=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\implies t=\dfrac{-(-32) \pm \sqrt{(-32)^2-4(8)(-95)} }{2(8)}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{1024+3040} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{4064} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16 \cdot 254} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16} \sqrt{254} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm 4 \sqrt{254} }{16}[/tex]

[tex]\implies t=\dfrac{8\pm \sqrt{254} }{4}[/tex]

As t ≥ 0,

[tex]\implies t=\dfrac{8+ \sqrt{254} }{4}\quad \sf only.[/tex]

[tex]\implies t=5.98 \sf \; s \; (2 d.p.)[/tex]

Therefore, the object strikes the ground at 5.98 seconds (2 d.p.).

To find if the object will reach a height of 300 feet above the ground, substitute h = 300 into the equation and solve for t:

[tex]\begin{aligned}\implies -16t^2+64t+190 & = 300\\-16t^2+64t+190-300 & =0\\-16t^2+64t-110 & =0\\-2(8t^2-32t+55) & =0\\8t^2-32t+55& =0\end{aligned}[/tex]

Use the quadratic formula to solve for t:

[tex]\implies t=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\implies t=\dfrac{-(-32) \pm \sqrt{(-32)^2-4(8)(55)} }{2(8)}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{1024-1760} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{-736} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16 \cdot -1 \cdot 46} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16} \sqrt{-1} \sqrt{ 46}}{16}[/tex]

[tex]\implies t=\dfrac{32 \pm 4i\sqrt{ 46} }{16}[/tex]

[tex]\implies t=\dfrac{8\pm \sqrt{ 46} \;i}{4}[/tex]

Therefore, as t is a complex number, the object will not reach a height of 300 feet.

The maximum height the object can reach is the y-coordinate of the vertex.  

Find the x-coordinate of the vertex and substitute this into the equation to find the maximum height.

[tex]\textsf{$x$-coordinate of the vertex}: \quad x=-\dfrac{b}{2a}[/tex]

[tex]\implies \textsf{$x$-coordinate of the vertex}=-\dfrac{64}{2(-16)}=-\dfrac{64}{-32}=2[/tex]

Substitute t = 2 into the equation:

[tex]\begin{aligned}t=2 \implies h(2)&=-16(2)^2+64(2)+190\\&=-16(4)+128+190\\&=-64+128+190\\&=64+190\\&=254\end{aligned}[/tex]

Therefore, the maximum height of the object is 254 feet.

It takes 2 seconds for the object to reach its maximum height.

The  sample size should be taken as 545.6 to obtain a margin of error of 0.042 for the estimation of a population proportion.

What is sample size?

The process of deciding how many observations or replicates to include in a statistical sample is known as sample size determination. Any empirical study with the aim of drawing conclusions about a population from a sample must take into account the sample size as a crucial component. The sample size chosen for a study is typically influenced by the cost, convenience, or ease of data collection as well as the requirement that the sample size have adequate statistical power.

As given in the question,

Confidence level is 95% and the margin of error is 0.042

So,  

1 - α = 0.95,

α = 0.05,

E = 0.042

planning value (p) = 0.5

To calculate Sample size the formula is:

[tex]n = \frac{p(1-p)(Z_{a/2})^2}{E^2}[/tex]

From the table we can find that:

[tex]Z_{a/2} = 1.96[/tex]

Putting the values given in the question in formula:

[tex]n = \frac{0.5(0.5)(1.96)^2}{(0.042)^2}[/tex]

[tex]n = \frac{(0.25)(1.96)^2}{(0.042)^2}[/tex]

[tex]n = \frac{(0.25)(3.841)}{0.00176}[/tex]

n = 545.6

Hence the sample size is 545.6

The area of the composite figure will be the sum of the area of the square and the area of the semicircle. The formula for determining the area of a square is expressed as

Area = length^2

From the diagram,

length = 12

Area of square = 12^2 = 144

The formula for determining the area of a semicircle is expressed as

Area = 1/2 * pi * radius^2

Radius = diameter/2

The diameter of the semicircle is 12. Thus,

radius = 12/2 = 6

pi = 3.14

Area of semicircle = 1/2 * 3.14 * 6^2 = 56.52

Area of composite figure = 144 + 56.52 = 200.52 in^2

There is a 5% chance that second graders will be faster than 94.597 wpm.

Sample size = 21

standard deviation = 10 wpm

SE = 10/sqrt(21) = 2.18 as a consequence.

Let X be the average reading speed of 21 second-grade students. z = (X - 91)/2.18 Normal(91,2.18) (91,2.18).

If the 95th percentile of a standard normal variable z is 1.65 [5% probability], the outcome is 91 + 1.65 x 2.18 = 94.597.

So there's a 5% chance that the average reading speed of a random sample of 21 second-graders will be faster than 94.597 wpm.

The total yards gained or lost is the algebraic sum so the resultant yards is -15 yards thus they lose 15 yards.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Subtraction = Minus of any two or more numbers.

Summation = addition of two or more numbers or variable

Let's consider all gained yards by positive (+) and all lost yards by negative (-).

Given that,

In the first play = +8 yards (gain)

In second play = -12 yards (lost)
