Answer:

Zero.

Step-by-step explanation:

The variable here is t where t is = time spent waiting in the line

The values for this variable and in this study, are normally distributed.

The mean waiting time = 55 minutes

The standard deviation = 33 minutes

What is the probability that t is greater than 88 minutes?

Now, the confidence interval about the mean for this study is:

[55-33], [55+33]  = [22, 88]

Therefore, all values of t fall within this lower and upper limit or interval.

If that is the case, and recalling also that the distribution of values is normal, then it is impossible for t to be greater than 88 minutes.

Hence, P[t>88] = 0

To 4 decimal places, that would be 0.0000

Answer:

Prob ( 2nd Red 'given' 1st Blue ) = 0.8  = 4/5

Step-by-step explanation:

Prob ( A I B ) = Prob (A ⋂ B) / P (B)

Prob ( 2nd Red 'given' 1st Blue ) = P ( 2nd Red & 1st Blue ) / P ( 1st blue)

P ( 1st blue & 2nd red ) = 32/128 , P ( 1st blue ) = 5/16

So, P ( 2nd Red I 1st Blue ) =  ( 32 / 128 ) / ( 5/16 )

= 0.8 = 4/5

Step-by-step explanation:

6x²-2x-15x+5=0

6x²-17x+5=0

[tex]x = \frac{17 + - \sqrt{ {17}^{2} - 4 \times 6 \times 5 } }{2 \times 6} [/tex]

[tex]x = \frac{17 + - 13}{12} [/tex]

x1= 5/2 x2= 1/3

The solutions of the given equation (2x-5)(3x-1)=0 are x=5/2 or x=1/3.

The given equation is (2x-5)(3x-1)=0.

Here, 2x(3x-1)-5(3x-1)=0

6x²-2x-15x+5=0

6x²-17x+5=0

(2x-5)(3x-1)=0

(2x-5)=0 or (3x-1)=0

2x=5 or 3x=1

Solution of quadratic equations are x=5/2 or x=1/3

Therefore, the solutions of the given equation are x=5/2 or x=1/3.

Answer:

C. 6

Step-by-step explanation:

Given that both ∆s are similar, the ratio of their corresponding sides as well as the ratio of their angle bisectors would be the same.

Therefore, from the figure given, we have:

[tex] \frac{8}{x} = \frac{4}{3} [/tex]

Cross multiply

[tex] x*4 = 8*3 [/tex]

[tex] 4x = 24 [/tex]

Divide both sides by 4

[tex] x = \frac{24}{4} [/tex]

[tex] x = 6 [/tex]

Answer:

The answer is 122 1/2 minutes.

Step-by-step explanation:

I got this answer by first subtracting 5.25-3.50=1.75 and that was how many minutes it took per mile then I multiplied 1.75x70=122.50 to get my answer.

If my answer is wrong im sorry this is my first one on this site.

If you are saying only positive 6 and 8, then there is only ONE.

Which gives you 48.

But if you are sayin both positive and negative, then there is two, 48,-48.

Because you multiply -6,8.

Answer: 0.19158

Step-by-step explanation:

Given: An undergraduate class has 24 biology majors and 17 chemistry majors.

Total students needs to be selected = 8

Number of ways to select 8 students out of 41= [tex]^{41}C_8[/tex]

Number of ways to select exactly two chemistry majors (i.e. rest 6 will be biology majors) = [tex]^{24}C_6\times ^{17}C_2[/tex]

Required probability = [tex]\dfrac{^{24}C_6\times ^{17}C_2}{^{41}C_8}[/tex]

[tex]=\dfrac{\dfrac{24!}{6!(24-6)!}\times\dfrac{17!}{2!(17-2)!}}{\dfrac{41!}{8!(41-8)!}}\\\\=\dfrac{134596\times136}{95548245}\\\\= 0.19158[/tex]

The probability of choosing exactly two chemistry majors = 0.19158

Answer:

1.01 m/s

Step-by-step explanation:

a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

t = Time

[tex]s_y[/tex] = Displacement in y direction = 1.2 m

[tex]s_x[/tex] = Displacement in x direction = 0.5 m

[tex]v_x[/tex] = Velocity in x direction

Displacement in y direction is given by

[tex]s_y=u_yt+\dfrac{1}{2}at^2\\\Rightarrow t=\sqrt{\dfrac{2s_y}{a}}\\\Rightarrow t=\sqrt{\dfrac{2\times 1.2}{9.81}\\\Rightarrow t=0.4946\ \text{s}[/tex]

[tex]s_x=v_xt\\\Rightarrow v_x=\dfrac{s_x}{t}\\\Rightarrow v_x=\dfrac{0.5}{0.4946}\\\Rightarrow v_x=1.01\ \text{m/s}[/tex]
