Step-by-step explanation:
For a sales promotion, the manufacturer places winning symbols under the caps of 23% of all its soda bottles. If you buy a six-pack of soda, what is the probability that you win something?
Answer:
The probability that you win something is 0.7916.
Step-by-step explanation:
Let X denote the number of soda bottles having winning symbols under the caps.
The proportion of soda bottles having winning symbols under the caps is, p = 0.23.
Six-pack of soda are randomly bought.
Every bottle is independent of the others to have the symbols under the caps.
The random variable X follows a binomial distribution with parameters n = 6 and p = 0.23.
Then the chance of winning something implies that at least 1 of the bottles in the six-pack have the symbol under the caps.
Compute the value of P (X ≥ 1) as follows:
[tex]P(X\geq 1)=1-P(X<1)\\\\=1-P(X=0)\\\\=1-{6\choose 0}(0.23)^{0}(1-0.23)^{6-0}\\\\=1-0.2084224\\\\=0.7915776\\\\\approx 0.7916[/tex]
Thus, the probability that you win something is 0.7916.
The probability of winning something from buying 6 bottles of the considered soda company is 0.7916 approximately.
How to find that a given condition can be modeled by binomial distribution?Binomial distributions consists of n independent Bernoulli trials.
Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
For this case, let we take:
X = the number of bottles out of 6 bottles having winning symbols.
Each bottle have the winning symbol(call it success) or not (call it failure).
Each bottle's result is independent of each other in a random picking (if 23% of the number of bottles manufactured is bigger or equal 6).
Then, we have X pertaining binomial distribution, as:
[tex]X \sim B(n=6, p = 0.23)[/tex]
(since success is a bottle having winning stickers, and as there are only 23% such bottles, so chance of success is 23% = 0.23(in decimal)).
Probability of not winning anything = P(X = 0)
From the probability function of binomial distribution, we get:
[tex]P(X = 0) = \: ^nC_xp^x(1-p)^{n-x} = \: ^6C_0(0.23)^0(1-0.23)^6 \approx 0.2084[/tex]
Thus, we get:
Probability of winning something = 1 - probability of not winning anything.
Probability of winning something ≈ 1- 0.2084 = 0.7916
Thus, the probability of winning something from buying 6 bottles of the considered soda company is 0.7916 approximately.

We have given that,
A web designer is placing images on a website using polar coordinates along the lines shown in the diagram.
Assume that the intersection of the lines is the pole and the right horizontal segment is the polar axis.
We have to determine equations that represent the lines on which the designer places the images.
What is the polar coordinate?The polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point is called the pole, and the ray from the pole in the reference direction is the polar axis.
The grid is split into 12 pieces and so they can be put into fractions with a denominator of either 3 or 6.
If you split the circle into portions that match the denominator, you can find 2/3, 17/6, and -11/3's on the circle.
Therefore options 1,3 and 5 are correct.

The speed of a boat in still water is 25 mph. The boat is traveling on a river with a current flowing south at 10 mph. At what angle upstream should the boat head to travel due west?
21.80°
23.58°
66.42°
68.20°
Answer:
B. 23.58
Step-by-step explanation:
I got it right
The correct option is an option (b).
Angle of upstream:If the boat is flowing in the opposite direction to the stream, it is called upstream. In this case, the net speed of the boat is called the upstream speed
Given that [tex]sin\theta=\frac{10}{25}[/tex]
Then the angle [tex]\theta[/tex] will be,
[tex]\theta= sin^{-1}(\frac{10}{25} )\\\theta=23.578[/tex]

Shawn waited at the bus stop for 15 min and saw 39 vehicles
go past. He counted a total of 124 wheels and noticed that only
cars and motorcycles went past. How many cars went past Shawn?
Step-by-step explanation:
let no of motorcycles be m and no of cars be c
4c + 2m = 124 --(1)
c + m = 39
c = 39 - m --(2)
sub (2) into (1):
4(39 - m) + 2m = 124
156 - 2m = 124
2m = 32
m = 16
therefore, c = 23
