Analyze the pre-image ABCD. What are the vertices of the final image if T-1, -2 •Ty=x is applied to figure ABCD? B"(3, 2) D - 2
schepotkina [342]

In Mathematics, it is possible to describe a graph as a pictographic depiction of a chart that helps to shape represents data or values, and in this question, the missing graph is defined in the attachment, and the solution can be defined as follows:

  • In the first place, we reflect on y=x.
  • The X and Y coordinates are changed in this reflection, which is given in the map:

                         A(2, 4)\to A'(4, 2)\\\\B(4, 4)\to B'(4, 4)\\\\C(3, 2) \to  C'(2, 3) \\\\D(1, 2)\to D'(2, 1)

  • We're doing the translation next.
  • The translation shifts figure 1 from the left and 2 from the y-coordinate by removing one at the x-coordinate and two that are:

                 A'(4, 2)\to A''(3, 0) \\\\B'(4, 4)\to B''(3, 2) \\\\C'(2, 3)\to C''(1, 1)\\\\D'(2, 1)\to D''(1, -1) \\\\

Therefore the final answer is "A''(3, 0); B''(3, 2); C''(1, 1); D''(1, -1)"

Huck and Jim are waiting for a raft. The number of rafts floating by over intervals of time is a Poisson process with a rate of
Harrizon [31]

Answer: 0.0081

Step-by-step explanation:

Let X be the number of rafts.

Given : The mean number of rafts floating : \lambda=0.4 rafts per day .

Then , for 7 days the number of rafts = \lambda_1=\lambda\times 7=0.4\times7=2.8 rafts per day .

The formula to calculate the Poisson distribution is given by :_

P(X=x)=\dfrac{e^{-\lambda_1}\lambda_1^x}{x!}

Now, the  probability that they will have to wait more than a week is given by :-

P(X>7)=1-P(X\leq7)\\\\=1-(P(0)+P(1)+P(2)+P(3)+P(4)+P(5)+P(5)+P(6)+P(7))\\\\=1-(\dfrac{e^{-2.8}2.8^{0}}{0!}+\dfrac{e^{-2.8}2.8^{1}}{1!}+\dfrac{e^{-2.8}2.8^{2}}{2!}+\dfrac{e^{-2.8}2.8^{3}}{3!}+\dfrac{e^{-2.8}2.8^{4}}{4!}+\dfrac{e^{-2.8}2.8^{5}}{5!}+\dfrac{e^{-2.8}2.8^{6}}{6!}+\dfrac{e^{-2.8}2.8^{7}}{7!})\\\\=1-0.991869258012=0.008130741988\approx0.0081

Hence, the required probability : 0.0081

GalinKa [24]

Answer:

  (13,-23)

Step-by-step explanation:

Comparing the image coordinates to the transformation rule, you see that ...

  (x -4, y +15) = (9, -8)

Adding (4, -15) to these coordinates, we get ...

  (x -4, y +15) +(4, -15) = (9, -8) +(4, -15)

  (x-4+4, y+15-15) = (9+4, -8-15)

  (x, y) = (13, -23) . . . . coordinates of D
