Answer:

A darts player practices throwing a dart at the bull’s eye on a dart board. Her probability of hitting the bull’s eye for each throw is 0.2.

(a) Find the probability that she is successful for the first time on the third throw:

The number F of unsuccessful throws till the first bull’s eye follows a geometric

distribution with probability of success q = 0.2 and probability of failure p = 0.8.

If the first bull’s eye is on the third throw, there must be two failures:

P(F = 2) = p

2

q = (0.8)2

(0.2) = 0.128.

(b) Find the probability that she will have at least three failures before her first

success.

We want the probability of F ≥ 3. This can be found in two ways:

P(F ≥ 3) = P(F = 3) + P(F = 4) + P(F = 5) + P(F = 6) + . . .

= p

3

q + p

4

q + p

5

q + p

6

q + . . . (geometric series with ratio p)

=

p

3

q

1 − p

=

(0.8)3

(0.2)

1 − 0.8

= (0.8)3 = 0.512.

Alternatively,

P(F ≥ 3) = 1 − (P(F = 0) + P(F = 1) + P(F = 2))

= 1 − (q + pq + p

2

q)

= 1 − (0.2)(1 + 0.8 + (0.8)2

)

= 1 − 0.488 = 0.512.

(c) How many throws on average will fail before she hits bull’s eye?

Since p = 0.8 and q = 0.2, the expected number of failures before the first success

is

E[F] = p

q

=

0.8

0.2

= 4.

The fraction of the body’s bones in the axial system is 40/103.

Given that, the axial system has 80 bones and the appendicular system has 126 bones.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Total number of bones in the human skeleton system

= 206

Fraction of bones in the axial system

= 80/206

= 40/103

Hence, the fraction of the body’s bones in the axial system is 40/103.

The exponents are solved and the number of times larger is n = 290,476,190,476.19

The exponential form is an easier way of writing repeated multiplication involving base and exponents. It has a base and a power

The exponential form of a number is a way of representing a number using exponents, where the base is typically a number greater than 1.

It is often used in mathematics and science to represent large or small numbers more efficiently. It can also be used to simplify certain mathematical operations, such as multiplication and division, by using the properties of exponents.

Given data ,

Let the first number be p = 6.1 x 10⁷

Let the second number be q = 2.1 x 10⁻⁴

And , the exponents are divided and the value of n is

To estimate how many times larger 6.1 x 10⁷ is than 2.1 x 10⁻⁴, we can divide the two numbers and then round the result to the nearest whole number.

n = 6.1 x 10⁷ / 2.1 x 10⁻⁴ ≈ 290,476,190,476.19

Rounding this to the nearest whole number gives us:

n ≈ 290,476,190,476

Hence , we can estimate that 6.1 x 10⁷ is approximately 290,476,190,476 times larger than 2.1 x 10⁻⁴

Answer:

7[tex]\frac{1}{2}[/tex] cups of water

Step-by-step explanation:

First you need to transfer 3 pints to cups which would be 6 cups. There is 1 pint in two cups. Next, you are going to add  the 6 cups to the 1[tex]\frac{1}{2}[/tex] cups, getting the cups of water Ian drinks :)

Part A: first multiply 2 by x and -3 → combine all like terms → Add 6 on both sides → subtract 6x from both sides.

Your final answer should be -5

step by step:    4x + 2(x-3) = 4x + 2x - 11

                          4x +2x -6 = 4x + 2x - 11

                                            6x -6 = 6x - 11

                                            6x = 6x -11 +6

                                            6x = 6x -5

                                            6x-6x= -5

                                            0 = -5

Part B: Add all like terms.

Answer:

1 inch represents 1/3 foot

Step-by-step explanation:

Scale = 51 inches

Actual = 17 feet or 204 inches

Use a ratio to compare the two 204:51 or 204/51 = 4

This means that the actual size is 4 times the scale size

Take 1 inch in the scaled size and multiply it by 4 to get the actual size to get 4 inches

4 inches = 1/3 foot, therefore 1 inch represents 1/3 foot

Step-by-step explanation:

The first thing we must observe is that the hourly rate for each candle is:

scented candles:

(1/12) / (20/60)

Simplifying:

= (1/12) / (10/30)

= (1/12) / (5/15)

= (1/12) / (1/3)

= (3/12)

= (1/4) inches / hour

Unscented candles:

(1/6) / (30/60)

Simplifying:

= (1/6) / (15/30)

= (1/6) / (3/6)

= (1/6) / (1/2)

= (2/6)

= (1/3) inches / hour
