Lance and rita were tied in a game. then lance go these scores 19, -7, 3, -11, 5. rita got these scores: 25, -9, 5, -9, 8. who had the higher score? how much higher was that higher score?

Rita had higher score than lance and she scored 11 more than lance.

Step-by-step explanation:

It is given that lance and Rita were tied in a game.

Lance scores : 19, -7, 3, -11, 5

Rita scores : 25, -9, 5, -9, 8

The sum of Lance scores is

The sum of Lance scores is 9.

The sum of Rita scores is

The sum of Rita scores is 20.

Since 20 > 9, therefore Rita had higher score than lance.

Difference between their score is

Rita score - lance score =

Therefore Rita scored 11 more than lance.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
