Th z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
hence:
z=(240-200)/20
z=2
Answer:
70° is your measurement for ∠t.
Step-by-step explanation:
Note that a straight line has an angle of 180°
It is given to us that ∠r and ∠t = 180°, and that m∠r = 110°
Plug in 110 for ∠r
110 + ∠t = 180
Isolate ∠t. Note the equal sign, what you do to one side, you do to the other. Subtract 110 from both sides
110 (-110) + ∠t = 180 (-110)
∠t = 180 - 110
∠t = 70
70° is your measurement for ∠t.

Answer:
4.17
Step-by-step explanation:
32 divided by 4 is 8, and 8 can be written as 7 4/4, since 4/4 equals to 1, therefore the answer should be 5 1/4
