Find the surface area and volume. show your work.

Answers

9514 1404 393

Answer:

area = 211 +7√205 ≈ 311.22 square unitsvolume = 273 cubic units

Step-by-step explanation:

Surface area

The length of the hypotenuse of the front facing triangle is given by the Pythagorean theorem:

d^2 = 13^2 +6^2 = 169 +36 = 205

d = √205

So, the perimeter of that triangle is ...

P = 13 +6 +√205 = 19 +√205

The total area of the rectangular faces of this triangular prism is then ...

rectangular face area = (base perimeter)·(prism height)

= (19 +√205)(7) = 133 +7√205

The area of the two triangular faces will be ...

triangular face total area = 2·(triangle area) = 2(1/2)(6)(13) = 78

Then the total surface area is ...

total surface area = rectangular face area + triangular face total area

total surface area = (133 +7√205) +78

surface area = 211 +7√205 ≈ 311.22 . . . . square units

Volume

The volume is the product of the area of the triangular base and the height of the prism.

V = Bh

V = (39)(7)

volume = 273 . . . . cubic units

A major airline knows that about 2 percent of passengers do not manage to show up for their flight. Consider a small aircraft having 50 seats, and suppose that an airline sells precisely 50 tickets for a specific flight. Assuming that all passsengers are independent and have the same probability of not showing up, compute the probability that

Answers

Answer:

a. The probability that the aircraft is fully occupied = 0.3642

b. The probability that between 1 and 5 (including 1 and 5) passengers do not show up is = 0.6354

Step-by-step explanation:

From the given information:

We are to compute the probability that:

a. The aircraft is fully occupied( i.e. all the passengers show up)

b. Between 1 and 5 (including 1 and 5) passengers do not show up

Given that:

Percentage of passengers that do not show up = 2% = 0.02

And the population of the passengers = 50; since 50 tickets are being sold for a specific flight.

Let assume X be the random variable that follows a binomial distribution, thus, the number of passengers from the aircraft with 50 passengers can be represented as:

[tex]X \sim Bin (n = 50, p =0.02)[/tex]

Thus;

The probability that the aircraft is fully occupied i.e. all the passengers show up is:

[tex]= (1 - 0.02)^{50}[/tex]

= 0.98⁵⁰

= 0.3642

Hence, The probability that the aircraft is fully occupied = 0.3642

b. The probability that between 1 and 5 (including 1 and 5) passengers do not show up is:

= P(X = 1) + P(X =2) + P(X = 3) + P(X = 4) + P(X = 5)

= [tex]=(^{50}_1) 0.02(1-0.02)^{50-1} +(^{50}_2) 0.02(1-0.02)^{50-2} + (^{50}_3) 0.02(1-0.02)^{50-3} + ... + (^{50}_5) 0.02(1-0.02)^{50-5}[/tex]

[tex]=(^{50}_1) 0.02(0.98)^{49} +(^{50}_2) 0.02(0.98)^{48} + (^{50}_3) 0.02(0.98)^{47} + ... + (^{50}_5) 0.02(0.98)^{45}[/tex]

= 0.6354

Hence, The probability that between 1 and 5 (including 1 and 5) passengers do not show up is = 0.6354

2 1/2cm is the answer for w

Step-by-step explanation:

the reason for this is because the total area for the triangle is 17 cm

and from whats shown on the rectangle it has only 12 so far so that means the w equals 2 1/2 because 12 + 2 1/2 + 2 1/2 = 17 so therefor the answer is 2 1/2cm

1) y = 3ˣ = b)

2) y = 3⁻ˣ = a)

3) y = -3ˣ = c)

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

y = 3ˣ

Now , the exponential function is plotted on the graph and is represented by the line b

y = 3⁻ˣ

Now , the exponential function is plotted on the graph and is represented by the line a

y = -3ˣ

Now , the exponential function is plotted on the graph and is represented by the line c

Hence , the exponential equations are solved
