It is estimated that 52% of drivers text while driving.
A. What is the probability that exactly 3 drivers text while driving if a police officer pulls over five drivers?
B. What is the probability the next driver texting while driving that the police officer pulls over is the fifth driver?
Answer:
a) 0.324 = 32.4% probability that exactly 3 drivers text while driving if a police officer pulls over five drivers
b) 0.0276 = 2.76% probability the next driver texting while driving that the police officer pulls over is the fifth driver.
Step-by-step explanation:
For each driver pulled, there are only two possible outcomes. Either they are texting, or they are not. The probability of a driver being texting is independent of any other drivers. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
It is estimated that 52% of drivers text while driving.
This means that [tex]p = 0.52[/tex]
A. What is the probability that exactly 3 drivers text while driving if a police officer pulls over five drivers?
This is [tex]P(X = 3)[/tex] when [tex]n = 5[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{5,3}.(0.52)^{3}.(0.48)^{2} = 0.324[/tex]
0.324 = 32.4% probability that exactly 3 drivers text while driving if a police officer pulls over five drivers.
B. What is the probability the next driver texting while driving that the police officer pulls over is the fifth driver?
None of the first four([tex]P(X = 0)[/tex] when [tex]n = 4[/tex]), and then the fifth, with 52% probability. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.52)^{0}.(0.48)^{4} = 0.0531[/tex]
0.0531*0.52 = 0.0276
0.0276 = 2.76% probability the next driver texting while driving that the police officer pulls over is the fifth driver.

The amount of orange juice in a bottle is modeled by the equation y=128-8x, where y is the number of ounces of juice in the bottle, and x is the number of servings or juice poured from the bottle.
How many servings are in a bottle?
Answer:
There are 16 servings in the bottle.
Step-by-step explanation:
The equation for the amount of juice left in the bottle is:
y = 128 - 8*x
Where x is the number of servings of juice poured from the bottle.
The total number of servings that are in the bottle is the value of x such that we have y = 0 (because in that point, we do not have more juice left)
Then we need to solve:
y = 0 = 128 - 8*x
8*x = 128
now we can just divide both sides by 8
x = 128/8 = 16
There are 16 servings in the bottle.

How do you write the inverse of the conditional statement belo "'If m<1 = 60°, then <1 is acute. " If m<1 = 60° then <1 is not acute. b If <1 is not acute, then m<1 = 60°. If <1 is acute, then m<1 = 60°. If m <1 = 60° then <1 is not acute.
Answer:
d
Step-by-step explanation:
The inverse of a conditional statement, makes both the hypothesis and conclusion or "p" and "q" negative. In other words, it adds a not to both sides.
So the inverse of "If p, then q" would be "If not p, then not q."
"If the measure of angle 1 does not equal 60 degrees, then angle 1 is not acute."

Use Euler's formula to find the missing number.
Vertices: 23
Edges: 39
Faces: ?
A. 12
B. 14
C. 16
D. 18
Answer: D. 18
Step-by-step explanation:
Euler's formula is Faces + Vertices = Edges + 2
Faces = Edges - vertices + 2
Faces = 39-23 + 2 = 18
Euler's formula is given by the formula F + V = E + 2. The number of faces in the given object is 18.
What is Euler's Formula?Euler's formula is given by the formula F + V = E + 2, in which F is the number of faces, V is the number of vertices, and E is the number of edges. For instance, a cube fits this formula since it has 6 faces, 8 vertices, and 12 edges.
The number of vertices and edges in the object is 23 and 39, respectively. Therefore, using Euler's formula the number of faces can be written as,
F + V = E + 2
F + 23 = 39 + 2
F = 39 + 2 - 23
F = 18
Hence, the number of faces in the given object is 18.

Nafeli is taking a multiple-choice exam with 10 questions and 3 choices per question. For eachquestion, there are two equally likely possibilities, independent of other questions. In the firstpossibility, she knows the answer, in which case she answers the question correctly. In the secondpossibility, she guesses the answer with probability of success 1/3.1. Given that Nafeli answered correctly the first question, what is the probability that she knewthe answer to that question
Answer:
0.75 = 75% probability that she knewthe answer to that question
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Answered correctly.
Event B: Knew the answer.
Probability of answering correctly:
0.5(knows the answer)
1/3 of 1 - 0.5 = 0.5(didn't know but guessed correctly). So
[tex]P(A) = 0.5 + 0.5\frac{1}{3} = 0.6667[/tex]
Probability of answering correctly and knowing the answer:
0.5, which means that [tex]P(A \cap B) = 0.5[/tex].
What is the probability that she knew the answer to that question?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.5}{0.6667} = 0.75[/tex]
0.75 = 75% probability that she knewthe answer to that question

Sample mean, xbar = Σx / n = 29.167
Rbar = ΣR/ n = 11.4
The R chart control limit is given by :
Rbar(1 - 3(d3/d2))
From the R chart :
d3 = 0.729 ; d2 = 3.735
Hence,
LCL = 11.4(1 - 3(0.729/3.735))
LCL = 11.4(0.4144578) =
LCL = 4.72481892 = 4.72
UCL = 11.4(1 - 3(0.729/3.735))
UCL = 11.4(1.5855421)
UCL = 18.075180 = 18.08
It is known that when a specific type of radish is grown in a certain manner without fertilizer the weights of the radishes produced are normally distributed with a mean of 40g and a standard deviation of 10g. When the same type of radish is grown in the same way except for the inclusion of fertilizer, it is known that the weights of the radishes produced are normally distributed with a mean of 140g and a standard deviation of 40g. Determine the proportion of radishes grown
Answer: hello your question is incomplete below is the missing part
Determine the proportion of radishes grown without fertilizers with weight less than 50grams
answer : p( x < 50 ) = 0.84
Step-by-step explanation:
Radish grown in without fertilizers ( normally distributed )
mean = 40 g
standard deviation = 10 g
Radish grown with fertilizers ( normally distributed )
Mean = 140 g
standard deviation = 40 g
Determine the proportion of radishes grown without fertilizers with weight less than 50 grams
lets assume x = radish without fertilizers
y = radish with fertilizers
hence
p( x < 50 ) = P ( (x-μ / б) < [tex]\frac{50-40}{10}[/tex] )
= p ( z < 1 ) = 0.5 + p ( 0 < z < 1 )
p( x < 50 ) = 0.5 + 0.3413 = 0.8413
