Answer:

The expected number of ticket holders that will fail to show for the flight is 13.9.

Step-by-step explanation:

For each ticket holder, there are only two possible outcomes. Either they fail to show up for the flight, or they do not. Ticket holders are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

5% of passengers fail to show for flights

This means that [tex]p = 0.05[/tex]

278 tickets sold

This means that [tex]n = 278[/tex]

What is the expected number of ticket holders that will fail to show for the flight?

[tex]E(X) = np = 278*0.05 = 13.9[/tex]

The expected number of ticket holders that will fail to show for the flight is 13.9.

Answer:

-2.75

-1.75

-0.75

0.25

1.25

Step-by-step explanation:

The value of x is given in the top row of the table. We can complete the rest of the table by plugging in the corresponding values of x into the equation and solve for y.

For example:

y = (-2) - 3/4 = -2.75

y = (-1) - 3/4 = -1.75

y = (0) - 3/4 = -0.75

y = (1) - 3/4 = 0.25

y = (2) - 3/4 = 1.25

Answer:

Step-by-step explanation:

In this case we will use the formula V= length × width × height

so, V=  2 1/4 × 1 × 1 1/4

=2 1/4 × 1 1/4

= 9/4 × 5/4

= 45/16

=2 13/16 cubic feet is the full capacity of the rectangular prism

then get the volume of the cube so, we will use the formula V= side times side times side

so, V= 1/4 times 1/4 times 1/4

V= 1/8 times 1/4

V= 1/32 cubic is the volume of the cube

then we will divide the full capacity of the rectangular prism to the volume of the cube

so, 2 13/16 divided by 1/32

so, 2 13/16 times 32/1

so, 45/16 times 32/1

=1,440/16

=90 small cubes can be packed in a rectangular prism in Part A

so, in Part B

V=  2 1/4 × 1 × 1 1/4

=2 1/4 × 1 1/4

= 9/4 × 5/4

= 45/16

=2 13/16 cubic feet is the volume of the rectangular prism

Answer:15.5

Step-by-step explanation:you can use the sin rule so set up x(height)/sin54.1 = 19.1/sin90 then times 19.1/sin90 by sin 54.1 to get 15.5

Answer:

Compound interest is better, by $14.36.

Step-by-step explanation:

Simple Interest:

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex]

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Total amount in compound interest:

$3,000 in a certificate of deposit that pays 2.8% interest, compounded annually for 4 years. This means, respectively, that [tex]P = 3000, r = 0.028, n = 1, t = 4[/tex]

So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(4) = 3000(1 + \frac{0.028}{1})^{4} = 3350.38[/tex]

Total amount in simple interest:

[tex]P = 3000, I = 0.028, t = 4[/tex]

So

[tex]E = P*I*t = 3000*0.028*4 = 336[/tex]

[tex]T = E + P = 3000 + 336 = 3336[/tex]

Which is better and by how much?

Higher earning with compound interest, so it is better.

3350.36 - 3336 = 14.36

Compound interest is better, by $14.36.

This question is incomplete, the complete question is;

The total weekly cost (in dollars) incurred by Lincoln Records in pressing x compact discs is given by the following function;

C(x) = 2000 + 2x -0.0001x²  (0 ≤ x ≤ 6000) .

(a) What is the actual cost incurred in producing the 1051st and the 2191st disc? (Round your answers to the nearest cent.)

(b) What is the marginal cost when x = 1050 and 2190? (Round your answers to the nearest cent.)

Answer:

a)

Actual cost for 1051st disc is $1.79

Actual cost for 2191st disc is $1.56

b)

the marginal cost are;

C'(1050) = $1.79

C'(2190) =  $1.56

Step-by-step explanation:

Given the data in the question;

C(x) = 2000 + 2x -0.0001x²

a)

What is the actual cost incurred in producing the 1051st and the 2191st disc? (Round your answers to the nearest cent.)

Actual cost for 1051st disc will be;

⇒ C(1051) - C(1050)  

= [ 2000 + 2(1051) - 0.0001×(1051)²] - [ 2000 + 2(1050) - 0.0001×(1050)² ]

= [ 2000 + 2102 - 110.4601 ] - [ 2000 + 2100 - 110.25 =

= 3991.5399 - 3989.75

= $ 1.7899 ≈ $1.79

Actual cost for 2191st disc will be;

⇒ C(2191) - C(2190)  

= [ 2000 + 2(2191) - 0.0001×(2191)²] - [ 2000 + 2(2190) - 0.0001×(2190)² ]

= [ 2000 + 4382 - 480.0481 ] - [ 2000 + 4380 - 479.61 ]

= 5901.9519 - 5900.39

= $ 1.5619 ≈ $1.56

Therefore,

Actual cost for 1051st disc is $1.79

Actual cost for 2191st disc is $1.56

b)

What is the marginal cost when x = 1050 and 2190? (Round your answers to the nearest cent.)

Marginal cost is; C'(x) = 2 - 0.0002x

so;

C'(1050) = 2 - 0.0002(1050) = 2 - 0.21 = $1.79

C'(2190) = 2 - 0.0002(2190) = 2 - 0.438 = $1.562 ≈ $1.56

Therefore; the marginal cost is;

C'(1050) = $1.79

C'(2190) =  $1.56

(a) Center is K (b) Radius is KI ,(c) Chord is KL,(d) Diameter is JKI,(e) Sectant is JL,(f) Tangent is GI,(g) Point of Tangency is H,(h) Minor Arc is JL,(i) Major Arc is HIJ,(j) Semicircle is HIL,(k) Center Angle is HKI,(l) Inscribed Angle is HIJ.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In our daily life, we always see circular objects for example our bike wheel.

The longest line which can be drawn inside the circle will be the diameter.

Area of the circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

As per the given circle,

(a)→ Center is at K

(b)→ Radius is at KI

(c)→ Chord is at KL

(d)→ Diameter is at JKI

(e)→ Sectant is at JL

(f)→ Tangent is at GI

(g) →Point of Tangency is at H

(h)→ Minor Arc is at JL

(i)→ Major Arc is at HIJ

(j)→ Semicircle is at HIL

(k)→ Center Angle is at HKI

(l) →Inscribed Angle is at HIJ

Hence "All parts of the circle have been shown above".
