Answer:
0.8214
Step-by-step explanation:
We have
F(x) = 1/b-a
With b = 7
And a = 0
Such that we have
1/7-0
= 1/7
Probability of x> 1.25
7-1.25
= 5.75
1/7 x 5.75
= 0.8214
Therefore the probability that a randomly selected passenger has a waiting time more than 1.25 minutes is = 0.8214.
Thank you!

The value of tan(11pi/6) is -√3/(3), the correct option is B.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We are given that;
The trigonometric function= tan(11pi/6)
The value of tan(11pi/6) can be found by using the unit circle or by using trigonometric identities. One way to find it is by using the identity tan(x) = sin(x)/cos(x) and plugging in 11pi/6 for x.
tan(11pi/6) = sin(11pi/6)/cos(11pi/6)
To find sin(11pi/6) and cos(11pi/6), we can use the reference angle pi/6 and recall that sin(pi/6) = 1/2 and cos(pi/6) = √3/2. Since 11pi/6 is in the fourth quadrant, where sine is negative and cosine is positive, we have:
sin(11pi/6) = -1/2
cos(11pi/6) = √3/2
Plugging these values into the expression for tan(11pi/6), we get:
tan(11pi/6) = (-1/2)/(√3/2)
tan(11pi/6) = -1/(√3)
We can rationalize the denominator by multiplying both numerator and denominator by √3:
tan(11pi/6) = (-1/(√3))(√3)/(√3)
tan(11pi/6) = -√3/(√3)(√3)
tan(11pi/6) = -√3/(√9)
tan(11pi/6) = -√3/(3)
Therefore, by the trigonometry the answer will be -√3/(3).

Kelly Slater and Andy Irons are in a surf competition among 10 competitors.
If all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place
2nd? Write your answer as a simplified fraction.
Answer:
The probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
Step-by-step explanation:
Since Kelly Slater and Andy Irons are in a surf competition among 10 competitors, to determine, if all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place 2nd, the following calculation must be performed:
1/10 x 1/9 = X
0.1 x 0.11 = X
0.01111 = X
1/90 = 0.011111 = X
Therefore, the probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.
Find the equation of the line that
is perpendicular to y = -2x + 1
and contains the point (8, 2).
[?]
y =
x+ [
Answer:
y=[tex]\frac{1}{2}x-2[/tex]
Step-by-step explanation:
Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept
y=mx+b
2=[tex]\frac{1}{2}[/tex](8)+b
2=4+b
B=-2

The perimeter of a rectangle is 73 inches. If the length is 16 inches, write and solve an equation to
find the width.
Answer:
Step-by-step explanation:
The equation for finding the perimeter of a rectangle is 2Lx2H
So since the length is 16, you multiply that by 2 to get 32.
Then you subtract 32 from 73 which leaves you with 41, then your equation is left as 2H=41, so you divide 41 by 2 which is 20.5, and that is your height

You roll a six sided number cube and flip a coin.What is the probability of rolling a number less than 6 and flipping heads?Write fraction in simplest form
Answer:
5/12
Step-by-step explanation:
Probability to roll a number<6 = 5/6 (each number has probability of 1/6, and there are 5 numbers < 6)
Probability to toss heads = 1/2
Condition "and" = multiplication of probabilities=5/6*1/2=5/12

Find the missing side. X is the hypotenuse 12 and 5 are the legs
Answer:
10.9
Step-by-step explanation:
Given that,
Hypotenuse = 12
One leg = 5
We need to find the another leg. Let it is b. We can solve it using Pythagoras theorem as follows :
[tex]H^2=h^2+b^2\\\\b^2=H^2-h^2\\\\b^2=12^2-5^2\\\\b=10.9[/tex]
So, another leg is 10.9.
the cost of 21 articles is equal to selling price of 18 articles. find the profit or loss percent.
Answer:
If all the items are sold, the profit percentage is 14.28%.
Step-by-step explanation:
Given that the cost of 21 articles is equal to selling price of 18 articles, to find the profit or loss percent the following calculation must be performed:
21 = 100
21 - 18 = X
21 = 100
3 = X
(3 x 100) / 21 = X
300/21 = X
14.28 = X
Therefore, if all the items are sold, the profit percentage is 14.28%.

A car travels 374 miles in five hours and 30 minutes. how many miles does it travel per hour?
Answer:
the answer is 68 miles
Step-by-step explanation:
you would change 5 hours and 30 minutes to 330 minutes and then you would do 374/330 and 330/330 that would be 1.13333333333 and 1 next you would do 1.13333333333 times 60 and 1 times 60 and it would equal to 68 miles in 60 minutes or 1 hour

Step-by-step explanation:
Given
[tex]\triangle JDC[/tex] similar to [tex]\triangle JKL[/tex]
Required
Find x
To do this, we make use of the following equivalent ratios
[tex]JK:JL = JD:JC[/tex]
This gives
[tex]98 : 63 = 7x + 7:27[/tex]
Express as fraction
[tex]\frac{98 }{ 63} =\frac{ 7x + 7}{27}[/tex]
Multiply both sides by 27
[tex]27 * \frac{98 }{ 63} =\frac{ 7x + 7}{27} * 27[/tex]
[tex]27 * \frac{98 }{ 63} =7x + 7[/tex]
[tex]3* \frac{98 }{ 7} =7x + 7[/tex]
[tex]3* 14 =7x + 7[/tex]
[tex]42 =7x + 7[/tex]
Collect like terms
[tex]7x = 42 - 7[/tex]
[tex]7x = 35[/tex]
Divide both sides by 7
[tex]x = 5[/tex]

C. triangle MPO is congruent to triangle MNO by SAS
Step-by-step explanation:
Enough information is given in the diagram so that we know ...
ΔMNO ≅ ΔOPM
by either the SSS or SAS congruence postulates.
What makes statement C false is the fact that the vertices listed are not corresponding vertices.

Additional comment
The wording here is of the form <angle 1> is congruent to <angle 2> by <some triangle congruence postulate>. A triangle congruence postulate can be used to show triangle congruence. Angle congruence must be based on a different claim.
2. Luego de entrevistar a diez de los pasajeros que viajaba en el bus que chocó intempestivamente contra un poste, se concluyó que el chofer era inocente. Identifica la población, la muestra, variable y el tipo de variable.
Respuesta:
Población = Todos los pasajeros en el autobús
Muestra = los 10 pasajeros entrevistados
Variable = inocencia del conductor; por tanto es una variable cualitativa
Explicación paso a paso:
La población se refiere a todo el conjunto de observaciones que están relacionadas con un evento o experimento en particular. Aquí, todos los pasajeros del vehículo constituyen la población, ya que nuestra investigación se basa en el vehículo.
La muestra es un subconjunto de la población que generalmente se elige al azar de manera que sea representativa de la población.
La variable que pretendemos medir es si el conductor es inocente o no. Por lo tanto, llamamos a esto la variable medida. Debido a que la culpa o la inocencia no es numérica, se considera una variable cualitativa.
