Answer:
B.
Step-by-step explanation:
First, notice that we can cancel out an x in the second term. Thus:

As with the last question, change the sign to multiplication and "flip" the second term:

Multiply straight across:

Cancel the (x+1) term:

Cannot be simplified further.
B.
Answer:
-93
Step-by-step explanation:
Θ=20
sinθm=1/2sinθb
Θ=47
sin20 mirror=1/2sin47bench
The first box plot shows the value of Q1 = 32 and Q3 = 37. Hence the Interquartile range = 37-32 = 5
The second box plot shows the value of Q1 = 29 and Q3 = 36, Hence the interquartile range = 36-29 = 7
Team B has bigger interquartile range than team A and it shows that the data spreads more than Team A's
It also shows that Team A's scores are more consistent
