Answers
Answer:
As the lines are neither parallel nor perpendicular.
Therefore, the correct answer is ''neither''.
Hence, option C is correct.
Step-by-step explanation:
Given
m₁ = 3/2
m₂ = -3/2
We know that when two lines are parallel, they have equal slopes
But
m₁ ≠ m₂
3/2 ≠ -3/2
As the m₁ and m₂ are not equal.
Hence, the lines are not parallel.
We know that when two lines are perpendicular, the product of their slopes is -1.
Let us check the product of two slopes m₁ and m₂
m₁ × m₂ = 3/2 × -3/2
= -9/4
= -2.25
As
m₁ × m₂ ≠ -1
Thus, the lines are not perpendicular.
Conclusion:
As the lines are neither parallel nor perpendicular.
Therefore, the correct answer is ''neither''.
Hence, option C is correct.

Passed Failed
Male 17 6
Female 34 12
Since P(mail |fail)=________ and P(male)=______, the two results are_____ so the events are________
Answers
Answer:
Step-by-step explanation:
From the given information:
Passed Failed Total
Male 17 6 23
Female 34 12 46
Total 51 18 69
[tex]P(male | fail) = \dfrac{P(male \cap fail)}{ P(fail)}[/tex]
[tex]P(male | fail) = \dfrac{\dfrac{6}{69} }{\dfrac{18}{69}}[/tex]
[tex]P(male| fail) = \dfrac{1}{3}[/tex]
[tex]P(male | fail) = 0.333[/tex]
[tex]P(male) = \dfrac{23}{69}[/tex]
[tex]P(male) = \dfrac {1}{3}[/tex]
[tex]P(male) = 0.333[/tex]
The two results are equal:
So the events are dependent.
. The length of the long-distance calls made by the employees of a company followed a normal distribution with a mean of 6.5 minutes and a standard deviation of 2 minutes. a. What is the probability that a call lasts less than 4 minutes
Answers
Answer:
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25) = 0.1056
Step-by-step explanation:
Step(i):-
Given mean of the population = 6.5 minutes
Given standard deviation of the Population = 2 minutes
Let 'X' be the random variable in normal distribution
Given X = 4
[tex]Z= \frac{x-mean}{S.D} = \frac{4-6.5}{2} = -1.25[/tex]
Step(ii):-
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25)
= 1-P(z>1.25)
= 1 - ( 0.5 +A(1.25)
= 1-0.5 - A(1.25)
= 0.5 - 0.3944 ( from normal table)
= 0.1056
Final answer:-
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25) = 0.1056

The number of potholes in any given 1 mile stretch of freeway pavement in Pennsylvania has a bell-shaped distribution. This distribution has a mean of 42 and a standard deviation of 10. Using the empirical (68-95-99.7) rule, what is the approximate percentage of 1-mile long roadways with potholes numbering between 22 and 52
Answers
Answer:
81.5% of 1-mile long roadways with potholes numbering between 22 and 52
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 42, standard deviation of 10.
The normal distribution is symmetric, so 50% of the measures are below the mean and 50% are above the mean
Approximate percentage of 1-mile long roadways with potholes numbering between 22 and 52:
22 = 42 - 2*10
So 22 is two standard deviations below the mean. Of the 50% of the measures that are below the mean, 95% are between two standard deviations below the mean(22) and the mean(42).
52 = 42 + 10
So 42 is one standard deviation above the mean. Of the 50% of the measures that are above the mean, 60% are between the mean(42) and one standard deviation above the mean(52).
In the desired interval, the percentage is:
[tex]P = 0.5*0.95 + 0.5*0.68 = 0.815[/tex]
81.5% of 1-mile long roadways with potholes numbering between 22 and 52

On one shelf of the school library 1/2 of the books are about sports. Joyce sees that 3/4 of the sports books are about basketball. What fraction of the books on the shelf are about basketball
Answers
The fraction of books on the shelf that are about basketball is [tex]\frac{3}{8}[/tex].
We know that half of the books on the shelf are about sports, so if we let "x" represent the total number of books, the number of sports books would be [tex](\frac{1}{2})x[/tex].
Next, Joyce observes that [tex]\frac{3}{4}[/tex] of the sports books are about basketball.
To find the fraction of books about basketball, we need to multiply the fraction of sports books by the fraction of basketball books within that category.
Therefore, we have:
[tex](\frac{3}{4}) \times(\frac{1}{2} )x =(\frac{3}{8} )x[/tex]
So, the fraction of books on the shelf that are about basketball is [tex]\frac{3}{8}[/tex].

the ordered pair (1,-3) is a solution of the system
Answers
Answer:
False
Step-by-step explanation:
Find the solution of:
2x + 3y = -7 --› eqn. 1
-x = 2y --› eqn. 2
Rewrite equation 2
-x = 2y --› eqn. 2
Divide both sides by -1
x = -2y
Substitute x = -2y in equation 1.
2x + 3y = -7 --› eqn. 1
2(-2y) + 3y = -7
-4y + 3y = -7
-y = -7
Divide both sides by -1
y = 7
If y = 7, then (1, -3) cannot be the solution of the system of equations.

Calculate the angle between (2,2,4) and (2,-1,1). The result is a familiar angle, so the answer is to be given exactly.
Answers
Answer:
The angle between [tex](2,2,4)[/tex] and [tex](2,-1,1)[/tex] is 60º.
Step-by-step explanation:
From linear algebra, we can determine the angle between both vectors by definition of dot point:
[tex]\cos \theta = \frac{\vec u\bullet \vec v}{\|\vec u\|\cdot \| \vec v\|}[/tex] (1)
Where:
[tex]\vec u[/tex], [tex]\vec v[/tex] - Vectors.
[tex]\|\vec u\|[/tex], [tex]\|\vec v\|[/tex] - Norms of vectors.
[tex]\theta[/tex] - Angle between vectors, measured in sexagesimal degrees.
If we know that [tex]\vec u = (2,2,4)[/tex] and [tex]\vec v = (2,-1,1)[/tex], then angle between vectors is:
[tex]\|\vec u\| = \sqrt{\vec u\bullet \vec u}[/tex] (2)
[tex]\|\vec u\| = \sqrt{2^{2}+2^{2}+4^{2}}[/tex]
[tex]\|\vec u\| \approx 4.899[/tex]
[tex]\|\vec v\| = \sqrt{\vec v\bullet \vec v}[/tex] (3)
[tex]\|\vec v\| = \sqrt{2^{2}+(-1)^{2}+1^{2}}[/tex]
[tex]\|\vec v\| \approx 2.450[/tex]
[tex]\vec u \bullet \vec v = (2,2,4)\bullet (2,-1,1)[/tex]
[tex]\vec u \bullet \vec v = 4-2+4[/tex]
[tex]\vec u \bullet \vec v = 6[/tex]
[tex]\cos \theta = \frac{6}{(4.899)\cdot (2.450)}[/tex]
[tex]\cos \theta = 0.5[/tex]
[tex]\theta = 60^{\circ}[/tex]
The angle between [tex](2,2,4)[/tex] and [tex](2,-1,1)[/tex] is 60º.
