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.

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.

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

Answer:

3 packs of water because its one one cent less then the other question

.25>.26

Step-by-step explanation:

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

Answer:

first one

Step-by-step explanation:

Answer:

86%

Step-by-step explanation:

88 times 5 = 440

78 + 86 + 96 + 94 = 354

440 - 354 = 86

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].
