Step-by-step explanation:
cam hits the bullseye in 8 darts out of 15 throws. what is the experimental probability that came next throws will hit the bullseye?
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.

1/2 x + 4
x + 6 - 1/2 x minus 2
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
Both expressions equal 6 when substituting 2 for x because the expressions are equivalent.
One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.

i need help please
Answer:
1/2 or 2
Step-by-step explanation:
If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.
The scale factor of the dilation is 1/2.
What is scale factor?Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given:
Before dilation
AC= 8, BC= 10 abd AB= 6
After dilation
AC= 4, BC= 5 and AB= 3
Now, scale factor
Scale factor = Dimensions of the new shape / Dimensions of the original shape.
So,
scale factor = 4/8 or 5/10 or 3/6 = 1/2
Hence, the scale factor is 1/2.

Three salesmen work for the same company, selling the same product. And, although they are all gold on
a weekly basis, each salesman earns his paycheck differently
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of
$1,300
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits
on the amount of commission he can earn
Salesman C does not corn any commission. His weekly salary is $900,
Suppose Salesmen A and B have the same number of sales and earn the same amount in Week of this
month. How many sales must they both have had?
Answer:
none of them are proportional. proportional would mean that they would earn 10 times as much if they sold 10 times as much.
A = 65 s maximum of 1300
B = 300 + 40 s
C = 900

Martin would save $1.01 per game by going to PC Richard & Son
Step-by-step explanation:
To solve this question, you have to divide the amount of money by the amount of games. You already know Best Buy's price for 1 game here (59.99).
Since the price is 117.96 for 2 games at PC, you can do
117.96÷2=58.98
59.99-58.98= $1.01
Oh, and even if you do 294.90÷5, you'd get the same thing.

The human skeleton can be divided into two systems. The axial system has 80 bones. It consists of the skull, spine, and ribs. The appendicular system has 126 bones. It consists of the shoulders, pelvis, and limbs. What fraction of the body’s bones are in the axial system? Give your answer in the simplest form. PLEASE HELP
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.
What is the fraction?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.

What is Exponential Form?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
