If it takes Charlie 45 minutes walking at 2.5 km/hr to get to the chocolate factory and it takes Willy Wonka 15 minutes walking
Mrac [35]

Answer:

Willy Wonka

Step-by-step explanation:

Given data

it takes Charlie 45 minutes walking at 2.5 km/hr

speed = distance /time

distance= speed*time

distance= 2.5*45

distance= 112.5 km

it takes Willy Wonka 15 minutes walking at 3.5 km/hr

distance= speed*time

distance= 3.5*15

distance= 52.5 km

Hence Willy Wonka stays closer

An artist wants to frame a square painting with an area of 400 square inches if x is the length of the one side of the painting
tatuchka [14]

There is only one solution to the equation.  A quadratic equation has 2 solutions a positive and a negative, but since we are looking for length, the answer can only be postive.  Area= side^2

              400= x^2

         sqrt(400)=x

          20 inches = x  

The length of one side is 20 inches


check: 20*20 = 400, which is the area of the square painting.

Problem 8-4 A computer time-sharing system receives teleport inquiries at an average rate of .1 per millisecond. Find the probab
Sphinxa [80]

Answer:  a) 0.9980, b) 0.0013, c) 0.0020, d) 0.00000026, e) 0.0318

Step-by-step explanation:

Problem 8-4 A computer time-sharing system receives teleport inquiries at an average rate of .1 per millisecond. Find the probabilities that the number of inquiries in a particular 50-millisecond stretch will be:

Since we have given that

\lambda=0.1\ per\ millisecond=5\ per\ 50\ millisecond=5

Using the poisson process, we get that

(a) less than or equal to 12

probability=  P(X\leq 12)=\sum _{k=0}^{12}\dfrac{e^{-5}(-5)^k}{k!}=0.9980

(b) equal to 13

probability= P(X=13)=\dfrac{e^{-5}(-5)^{13}}{13!}=0.0013

(c) greater than 12

probability= P(X>12)=\sum _{k=13}^{50}\dfrac{e^{-5}.(-5)^k}{k!}=0.0020

(d) equal to 20

probability= P(X=20)=\dfrac{e^{-5}(-5)^{20}}{20!}=0.00000026

(e) between 10 and 15, inclusively

probability=P(10\leq X\leq 15)=\sum _{k=10}^{15}\dfrac{e^{-5}(-5)^k}{k!}=0.0318

Hence, a) 0.9980, b) 0.0013, c) 0.0020, d) 0.00000026, e) 0.0318

Let X and Y be the following sets: X={0,12,23} Y={3,12,15} Which of the following is the set X \ Y?
Digiron [165]

Answer:

Step-by-step explanation:

X={0,12,23}

Y={3,12,15}  

X \ Y = { 0 , 23}

X/Y means the element should be only in X. We have remove the element in X if it is in Y

In this 0 and 23 is only in X

12 is X and Y. So it wont come in X/Y

What is the slope of y=-1+3xy=−1+3xy, equals, minus, 1, plus, 3, x?
kari74 [83]

Answer:

3

Step-by-step explanation:

Given the function: y=-1+3x

Slope=\dfrac{\text{Change in y axis}}{\text{Change in x axis}}

The above is the derivative of y with respect to x.

Therefore, for

y=-1+3x\\\dfrac{dy}{dx}=3

Therefore the slope of the function is 3.
