Answer:

x=8.5

Step-by-step explanation:

∠AOC=68

∠COD= (2x+5)

∠AOC and ∠COD are complimentary angles. This means that when you add them together you get 90.

∠AOC + ∠COD = 90

68 + (2x+5) =90

2x+5=22

2x=17

x=8.5

Lera25 [3.4K]

According to the data null and alternative hypotheses should be:

  • H_{0}: P=0.60

What is 1/10th of 2,871,000?
abruzzese [7]
This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

\frac{2,871,000}{10} =287,100

Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
