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

Answers

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) 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
