A game is played using one die. if the die is rolled and shows a 2, the player wins $45. If the die shows any number other than

miskamm [114]

Answer:

The game's expected value is of -$1.5.

Step-by-step explanation:

Expected value:

Probability of each outcome multiplied by the outcome.

One out of 6 sides is 2:

1/6 probability of the player earning 45 - 9 = $36.

5/6 probability of the player losing $9. So

$E = 36\frac{1}{6} - 9\frac{5}{6} = \frac{36 - 45}{6} = -\frac{9}{6} = -1.5$

The game's expected value is of -$1.5.

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Let's see if the sequence is Arithmetic or Geometric :}$

$\textsf{If the difference between successive terms is }$ $\textsf{equal then, the terms are in AP}$

$\sf{ \dfrac{14}{3}- \dfrac{13}{3} = \dfrac{1}{3}}$

$\sf{ {5}{}- \dfrac{14}{3} = \dfrac{15-14}{3} =\dfrac{1}{3}}$

$\textsf{Since the common difference is same, }$ $\textsf{we can infer that it's an Arithmetic progression}$ $\textsf{with common difference of } \sf \dfrac{1}{3}$

SpyIntel [72]

Answer:

B. The student incorrectly calculated the scale factor to be –2

Step-by-step explanation:

Given that :

After a dilation with a center of (0, 0), a point was mapped as (4, –6) → (12, y).

The student determined y to be -2

If a figure dilated with a center of (0, 0) and scale factor k, then

(x , y) → (kx , ky)

(4, -6) → (12, y)

$k = \dfrac{x'}{x}$

$k = \dfrac{12}{4}$

k = 3

Thus; the scale factor is 3

Now; the y-coordinate can now be calculated as;

ky = (3 × -6)

ky = -18

Therefore; the value of y = -18 and the student incorrectly calculated the scale factor to be -2.
