The length of the base is 32.6
3.3 + 3.3 = 6.6
Subtract 6.6 from 71.8 : 65.2
Divide that by 2 : 32.6
Combine like terms so you end up with 10x+2y
The empirical probability of a 4 or 5 is
(count of outcome = 4 or 5)/(count of all outcomes) = (44 +40)/240 = 7/20
The problem statement asks you to assume the outcomes will remain in this proportion going forward. That is, the number of outcomes (n) of 4 or 5 in the next 60 rolls of the number cube is expected to satisfy
7/20 = n/60
Multiplying that by 60 gives
n = 60*(7/20) = 21
Selection D is appropriate.
The answer is D because if you do 66÷88 you'll wind up getting 0.75 hope this helps
Answer:
So first you know automatically that either side of the line is 180 degrees. So 180-155 would get you 25 degrees so you now know that y=5. we know that it is also a right angle therefore you divide 65 (x-90) by 13 and you get that x is also equal to five
Step-by-step explanation:
