Let X Be The Event That A Person Chosen At Random From Anywhere On Earth Will Live In Either Asia, Europe,

Answers

Answer 1

Using probability concepts, it is found that P(X) = 0.68.

The probabilities given are:

0.22 probability of a person living in Africa.0.08 probability of a person living in North America.0.06 probability of a person living in South America.0.55 probability of a person living in Asia.0.07 probability of a person living in Europe.0.01 probability of a person living in Oceania.

Event X is the probability of living in either South America, Asia or Europe, thus it's probability is the sum of these three probabilities, that is:

[tex]P(X) = 0.06 + 0.55 + 0.07 = 0.68[/tex]

Hence, P(X) = 0.68.

Answer 2

Answer:

0.68

explanation:

you're adding the numbers on the graph together

South America = 0.06

Europe = 0.07

Asia = 0.55

0.06 + 0.07 + 0.55 = 0.68

Answers

1. Find Slope
m = y2-y1/x2-x1
m = -6 - 5/2-4
m = -11/-2
m = 11/2

2. Write equation with know information
y = mx + b
y = 11/2x + b


3. Choose any of the two points (doesn’t matter which in you choose) and replace the x and y value into the equation
y = 11/2x + b (4,5)
5 = 11/2(4) + b
5 = 22 + b

Use algebra and solve for b
5 - 22 = b
b = -17

State all the information you know
m = 11/2 b = -17

Write the equation

A coin is tossed 12 times. What is the probability of obtaining five heads and seven tails?

Answers

I believe the probability would be 0.19336

Answer:

99/512 = 0.193359375

Step-by-step explanation:

Each sequence of 5 H's and 7 T's has probability of occurring equal to      1/2^12 (1 divided by 2 to the twelfth power).

Since the number of 5 H, 7 T sequences is equal to C(12,5) =                           the number of combinations of 12 things taken 5 at a time =

12 * 11 * 10 * 9 * 5 / (5 * 4 * 3 * 2 * 1) =

792,

we have that the probability of obtaining 5 H's and 7 T's =

the sum of the probabilities of all of the sequences =

1/2^12 + 1/2^12 + 1/2^12 + . . . + 1/2^12, 792 times =

792(1/2^12) =

99 / 2^9 =

The graph below is the function f(x)
Find lim x -> -1- f(x)=

Answers

As x approaches -1 from the left, the graph of f(x) leads you to the point (-1, 3), so the limit from the left is 3.

As x approaches -1 from the right, the graph leads to the point (-1, -3), so the limit from the right is -3.

The one-sided limits do not match, so the two-sided limit does not exist.

But f(x) is still defined at x = -1; this is indicated by the point (-1, -1). So f (-1) = -1.

We have found all the given limits for all the function.

What is limit of a function?

The limit of a function is a key notion in calculus and analysis that describes how the function behaves near a certain input.

A​ five-speed bicycle has a chain linking the pedal sprocket to the gears on the rear wheel. The ratio of pedal turns to​ rear-wheel turns in first gear is 8 to 17. How many times in first gear does the rear wheel turn if the pedals turn 160 ​times?

Answers

9514 1404 393

Answer:

  340

Step-by-step explanation:

Multiply each number in the ratio by 20:

  pedal : wheel = 8 : 17 = 160 : 340

The rear wheel turns 340 times when the pedal turns 160 times.

__

Additional comment

As a reasonableness check, realize that 17 is just slightly more than 2 times 8. Then the number of rear wheel turns will be slightly more than 2 times 160.

A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 151 feet per second from an initial height of 95 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation:
h = - 16t² + 151t +95

Answers

Answer:

Step-by-step explanation:

144 = -16t² + 151t + 95

  0 = -16t² + 151t - 49

quadratic formula

t = (-151 ±√(151² - 4(-16)(-49))) / (2(-16))

t = (-151 ± 140.23195) / -32

t = 0.34 s

t = 9.10 s
