The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 minutes. Find the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes.
Answers
Answer: 0.75
Step-by-step explanation:
Given : Interval for uniform distribution : [0 minute, 5 minutes]
The probability density function will be :-
f(x) = 1/5-0 = 1/5 = 0.2, 0<x<5
The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-
Hence, the probability that a randomly selected passenger has a waiting time greater than 1.25 minutes = 0.75

Find the directional derivative of the function f(x,y)=2cos(y)exf(x,y)=2cos(y)ex at the point (0,π6)(0,π6) in the direction of the vector v=⟨−8,6⟩v=⟨−8,6⟩.
Answers
Answer:
[tex]D_u f(0,\pi/6)=\frac{4\sqrt{3}-3}{5}[/tex]
Step-by-step explanation:
We are given that
[tex]f(x,y)=2cos(y)e^{x}[/tex]
Point=([tex]0,\pi/6[/tex])
Vector v=<-8,6>
We have to find the directional derivative of the function.
[tex]f_x(x,y)=2cos(y)e^{x}[/tex]
[tex]f_x(0,\pi/6)=\sqrt{3}[/tex]
[tex]f_y(x,y)=-2sin(y)e^{x}[/tex]
[tex]f_y(0,\pi/6)=-1[/tex]
[tex]|v|=\sqrt{(-8)^2+6^2}=\sqrt{100}=10[/tex]
[tex]\hat{u}=\frac{v}{|v|}=\frac{-8i+6j}{10}=\frac{1}{10}(-8i+6j)[/tex]
[tex]\nabla f(0,\pi/6)=<f_x(0,\pi/6),f_y(0,\pi/6)>=<\sqrt{3},-1>[/tex]
Now, the directional derivative in the direction of v at point (0,[tex]\pi/6[/tex]) is given by
[tex]D_u f(0,\pi/6)=\nabla f(0,\pi/6)\cdot \hat{u}[/tex]
By using the formula
[tex]D_u f(x,y)=\nabla f(x,y)\cdot \hat{u}[/tex]
[tex]D_u f(0,\pi/6)=<\sqrt{3},-1>\cdot <-\frac{8}{10},\frac{6}{10}>[/tex]
[tex]D_u f(0,\pi/6)=-\frac{4\sqrt{3}}{5}-\frac{3}{5}=-\frac{1}{5}(4\sqrt{3}+3)[/tex]

A pound has 60 German Shepherds and 40 Great Danes of both sexes. If they breed with each other randomly, what is the probability that the puppies are: (i) pure breed German Shepherds, (ii) pure breed Great Danes, (iii) German Shepherd-Great Danes
Answers
Answer:
(i) pure breed German Shepherds,= 0.6
(ii) pure breed Great Danes,= 0.4
(iii) German Shepherd-Great Danes= 0.24
Step-by-step explanation:
The probability of success for the German shepherd is 60/100 0r 6/10 0r 0.6
The probability of failure for the German shepherd is 40/100 0r 4/10 0r 0.4
The probability of success for the Great Danes is 40/100 0r 4/10 0r 0.4
The probability of failure for the Great Danes is 60/100 0r 6/10 0r 0.6
The probability that it is a pure German shepherd is 60/100 0r 6/10 0r 0.6
The probability that it is a pure the Great Danes is 40/100 0r 4/10 0r 0.4
The probability that the puppies are: German Shepherd-Great Danes is given by since the events are independent
P (GS ∩ GD) = 0.6* 0.4= 0.24
The data in which table represents a linear function that has a slope of zero? X -5 -4 -3 -2 -1 у 5 5 5 5 5 w х 1 2 3 4 5 y -5 -4 -3 -2 -1 X -5 -4 -3 -2 y 5 4 3 2
Answers
Answer: the answer is choice b
Step-by-step explanation:
The data in the first table represents a linear function that has a slope of zero
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Slope (m) = change in y / change in x
From the first table, using the point (-5, 5) and (-1, 5), hence:
Slope = (5 - 5)/(-1 - (-5)) = 0
The data in the first table represents a linear function that has a slope of zero

Answer:
f(4) = 19
Step-by-step explanation:
Plug in 4 for x in the given equation:
f(x) = 5x - 1
f(4) = 5(4) - 1
Simplify. Remember to follow the order of operations, PEMDAS. First multiply, then subtract:
f(4) = (5 * 4) - 1
f(4) = 20 - 1
f(4) = 19
f(4) = 19 is your answer.

Which number line can be used to find the distance between (-1,2) and (-5,2)
Answers
Answer:
The number line is y = 2.
Step-by-step explanation:
We are given the points (-1,2) , (-5,2) and we have to find the number line that can be used find the distance between them.
The y coordinate of the two points is
same (equal to 2) , so the number line that can be used to find the distance between them is y = 2.
Distance between the points = |-5+1| = 4

Answers
====================================================
Explanation:
We're told that "given that it is less than 8", so we only focus on these values {1,2,3,4,5,6,7}. There are B = 7 items in this set.
Of those, the set {1,2,3,4,5,6} are less than 7. There are A = 6 items in this set.
The probability we're after is A/B = 6/7 = 0.8571
Answer:

4 cm
2 cm
5 cm
6 cm
A 34 cm2
B 44 cm
54 cm
D 46 cm
Answers
Answer:
the answer is D 46 cm
Step-by-step explanation:
first you need to find the missing side measurements cutting in two separate figures. if one side is 2 you know the other side is also 2 same with the 4 if the top is 4 the bottom is 4 too so now you have the measurements for the first figure now you finder the area applying the formula
A=bxh
A= 4*2=8
second figure you know that one part of the rectangle top is 5 and if you add the 4 of the first figure give you the measurement of the top
5+4=9 so if the top is 9 the bottom is also 9
finally to find the other side you know the side is 6 and since you know one part of the first figure is 2 you need to subtract 6-2=4
A=bxh
A=9*4=28
once you have both you can add it 28+8=46
