Answer A makes no sense because you cannot correlate anything with a difference between the x and y values.

Answer B is false, as the difference in y-values increases for every x-value:

$36 - 9 = 27$
$144 - 36 = 108$
$576 - 144 = 432$
$2304 - 576 = 1728$

Answer D also makes no sense, as there is no factor for both x and y values.

The answer is C, as the differences between y-values are increased by a factor:

$27 * 4 = 108$

$108 * 4 = 432$

$432 * 4 = 1728$

Resistors. An electrical engineer has two boxes of resistors, with four resistors in each box. The resistors in the first box ar

Dafna11 [192]

Answer:

A. Sample Space = S = {(9, 18),(9, 19),(9, 20),(9, 21),(10, 18),(10, 19),(10, 20),(10, 21),(11, 18),(11, 19),(11, 20),(11, 21),(12, 18),(12, 19),(12, 20),(12, 21)}

B. {(9, 18),(10, 18),(11, 18),(12, 18)}

C. {(9, 18),(9, 19),(10, 18)}

D. {(9, 18),(9, 19),(10, 18),(11, 18),(12, 18)}

E. B(complement) ∩C = {(9, 19)}

Step-by-step explanation:

The Sample Space would contain each element of the box A associated with each element of the box B.

A. Sample Space = S = {(9, 18),(9, 19),(9, 20),(9, 21),(10, 18),(10, 19),(10, 20),(10, 21),(11, 18),(11, 19),(11, 20),(11, 21),(12, 18),(12, 19),(12, 20),(12, 21)}

B. Let the Outcomes in the event B, the event that the second resistor has a resistance less than 19 be denoted by J then

J= {(9, 18),(10, 18),(11, 18),(12, 18)}

C. Let the outcomes in the event C, the event that the sum of the resistances is equal to 28 be denoted by L then

L = {(9, 18),(9, 19),(10, 18)}

D. The outcomes in B∪C contains all the elements of B and C

B∪C=J∪L= {(9, 18),(9, 19),(10, 18),(11, 18),(12, 18)}

E. B complement contains those elements of the Sample Space which are not the elements of Set B.

B complement= S-B= {(9, 19),(9, 20),(9, 21),(10, 19),(10, 20),(10, 21),(11, 19),(11, 20),(11, 21),(12, 19),(12, 20),(12, 21)}

B(complement) ∩C contains those elements of B and C which are common to both B complement and C.

B(complement) ∩C = {(9, 19)}
