Point (a, b) is transformed by the rule (a, b−4) .

seraphim [82]

Any change made in the first coordinate, is a change of the point in the horizontal direction.

Similarly, any change made in the second coordinate, is a change of the point in the vertical direction.

Thus the rule (a, b)→(a, b-4) is a rule which affects the point only in the vertical position.

The point (a, b) is shifted 4 units down (because of -4)

Answer: a translation of 4 units down

Debora [2.8K]

The number of 256×8 that are needed to make 4096×8 will be found as follows:
(4098×8)/(256×8)
=16.0078
there we conclude that:
sixteen 256×8 are needed to make 4096×8.

An ordinary Fair die is a cube with the number 1 through 6 on the sides (represented by painted spots). imagine that such a die

aleksandrvk [35]

Event A Answer: $\frac{5}{12}$

Step-by-step explanation:

sum greater than 7 leaves are the following combinations for 8, 9, 10, 11, and 12:

8 = 26, 35, 44, 51, 62 (5 possibilities)

9 = 36, 45, 54, 63 (4 possibilities)

10 = 46, 55, 64 (3 possibilities)

11 = 56, 65 (2 possibilities)

12 = 66 (1 possibility)

This is a total of 15 possibilities out of 36 total: $\frac{15}{36}$ = $\frac{5}{12}$

***********************************************************************************

Event B Answer: $\frac{1}{2}$

Step-by-step explanation:

sum is an even number means both dice are odd or both dice are even. That results in the following combinations:

11 13 15

22 24 26

31 33 35

42 44 46

51 53 55

62 64 66

This is a total of 18 possibilities out of 36 total: $\frac{18}{36}$ = $\frac{1}{2}$
