A company makes Citi bikes. 95% (i.e., 0.95) pass final inspection. Suppose that 5 bikes are randomly selected.
a. What is the probability that exactly 4 of these 5 sports bikes pass final inspection?
b. What is the probability that less than 3 of these 5 sports bikes pass final inspection?
Using the binomial distribution, it is found that the probabilities are given as follows:
a) 0.2036 = 20.36%.
b) 0.0011 = 0.11%.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, the parameters are given as follows:
p = 0.95, n = 5.
Item a:
The probability is P(X = 4), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{5,4}.(0.95)^{4}.(0.05)^{1} = 0.2036[/tex]
Item b:
The probability is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(0.95)^{0}.(0.05)^{5} \approx 0[/tex]
[tex]P(X = 1) = C_{5,1}.(0.95)^{1}.(0.05)^{4} \approx 0[/tex]
[tex]P(X = 2) = C_{5,2}.(0.95)^{2}.(0.05)^{3} = 0.0011[/tex]
Then:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0 + 0 + 0.0011 = 0.0011.

Answer: The square root of π has attracted attention for almost as long as π itself. When you’re an ancient Greek mathematician studying circles and squares and playing with straightedges and compasses, it’s natural to try to find a circle and a square that have the same area. If you start with the circle and try to find the square, that’s called squaring the circle. If your circle has radius r=1, then its area is πr2 = π, so a square with side-length s has the same area as your circle if s2 = π, that is, if s = sqrt(π). It’s well-known that squaring the circle is impossible in the sense that, if you use the classic Greek tools in the classic Greek manner, you can’t construct a square whose side-length is sqrt(π) (even though you can approximate it as closely as you like); see David Richeson’s new book listed in the References for lots more details about this. But what’s less well-known is that there are (at least!) two other places in mathematics where the square root of π crops up: an infinite product that on its surface makes no sense, and a calculus problem that you can use a surface to solve.

In order to finance furniture for an office in a new retail store, Tools for Schools signs a 140-day simple discount note with a maturity value of $19300. Find the proceeds if the discount rate is 13.5%.
Answer:
I think it would be $ 66.23
I hope I can help you
have a nice day.
The proceeds of the simple discount note are approximately $18,296.16.
To find the proceeds of the simple discount note, we can use the formula:
Proceeds = Maturity Value - Discount
Where:
Maturity Value = $19,300 (given)
Discount = Maturity Value * Discount Rate * Time
The discount rate is 13.5%, which can be written as 0.135 in decimal form. The time is 140 days. Now, let's calculate the discount:
Discount = $19,300 * 0.135 * (140/360)
we divide by 360 because simple interest is typically based on a 360-day year.
Discount = $19,300 * 0.135 * 0.388888...
Discount ≈ $1,003.84 (rounded to two decimal places)
Now, let's find the proceeds:
Proceeds = $19,300 - $1,003.84
Proceeds ≈ $18,296.16 (rounded to two decimal places).

b demand continually exceeding supply, leading to an imbalance of money and goods in the
market
C a natural consequence of the use of money instead of trade goods
d government intervention demanding that prices be raised
Answer:
D. government intervention demanding that prices be raised

Inflation means when prices increase and fall in purchasing value of money. The only logical answer would be "Government intervention demanding that prices be raised. " Because it is the only one that talks about prices increasing.
The answer choice which is a cause of inflation is; Choice B; demand continually exceeding supply, leading to an imbalance of money and goods in the market.
What is then cause of Inflation?Inflation is simply a measure of the rate of rising prices of goods and services in an economy. More specifically, a surge in demand for products and services can cause inflation as consumers are willing to pay more for such product in less supply.

A recipe for making paste calls for a ratio of flour to water of 4:2. If you only have 2 cups of flour, how much water should you put in? Explain how you know.
Answer:
1 Cup of Water
Step-by-step explanation:
Well, this is pretty simple.
This questions topic is known as Equivalent Ratios.
To find an equivalent ratio, add or divide the numbers by the same amount.
Let's do it together.
4:2 is the ratio we already have. If we have to make it have 2 cups of flour, let's divide 2 on both sides.
Since 4 divided by 2 is 2, and 2 divided by 2 is 1,
We can confirm that you would need to put in 1 cup of water.

Find the exact value of 0 tan165 using the appropriate identity formula. Rationalize denominator if needed.
Answer:
[tex]tan165^0 = -2 + \sqrt{3}[/tex]
Step-by-step explanation:
Given;
tan165⁰
165⁰ is in the second quadrant, and sine is positive in this quadrant, thus tan will be negative.
In second quadrant, tanθ = -tan(180 - θ)
tan165⁰ = -tan(180-165)
tan165⁰ = -tan15⁰
[tex]- tan15^0 = -tan(60 - 45)\\\\ tan(\alpha - \beta) = \frac{tan \alpha -\ tan \beta}{1 + tan \alpha tan \beta}\\\\ -tan(60 - 45) = -(\frac{tan 60 - tan 45}{1+tan60tan45} )\\\\ -(\frac{tan 60 - tan 45}{1+tan60tan45} )= -(\frac{\sqrt{3} \ - 1}{1+ \ \sqrt{3} } ) = \frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} }\\\\\frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} } =( \frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} })(\frac{1 - \ \sqrt{3}}{1 - \ \sqrt{3}} ) = \frac{1-\sqrt{3} -\sqrt{3} \ +\ 3 }{1\ -\ 3} = \frac{4-2\sqrt{3} }{-2}[/tex]
[tex]\frac{4-2\sqrt{3} }{-2} = -2 + \sqrt{3}[/tex]
Therefore, [tex]tan165^0 = -2 + \sqrt{3}[/tex]

At summer camp, there are 3 boys for every 4 girls. If there are 63 boys & girls at camp, how many boys are there?
Answer:
turn it into an equation
since the total number of students is 63 and for every 3 boys are 4 girls
3x + 4x = 63
7x = 63
x = 63/7
x= 9
to get the number of boys
3 x 9 = 27
therefore the number of boys is 27
