Answer:

Step-by-step explanation:
Given: Trey's test score average decreased by 14 points this semester.
To find: a signed number to represent this change in average.
Solution:
The decrease can be denoted by minus
sign and increase can be denoted by plus
sign.
So, a signed number to represent the change in test score average is 
350 is the solution because the slope is 50meters/1minute
50✖️7=350
Or 250+50+50=350
Each question is either true or false, so the sample space is 2, true and false, two states only.
what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.
what's the probability that she got all four correct, we simply multiply the probability of each,
