Answer:
2:3
Step-by-step explanation:
54/3=18
18/3=6
6/3=2
81/3=27
27/3=9
9/3=3
so,2:3
Yes, all square roots of non square numbers are irrational. That means that the sqrt of a whole number will never be a fraction, but always an irrational number or an integer.
Second question, not entirely sure who "it" is...
The divisors of 2205 are: 1, 3, 5, 7, 9, 15, 21, 35, 45, 49, 63, 105, 147, 245, 315, 441, 735, 2205.
Trying them out small to large:
√(2205/3) = <span>
27,11088...</span> irrational
√(2205/5) = 21 rational!
So 5 is a divisor because 5*441 = 2205. Also √441=21 and 21 is rational.
The answer must be No. However, the reasons offered here don't make any sense in relation to the way traffic lights work. I believe the best choice may be
... because the results are likely to occur by chance.
If lights are randomly red or green with equal probability, the probability of encountering 9 of 16 lights in any particular state is about 0.17, high enough to say it could occur by chance.
Lights that are not coordinated are rarely programmed that way, more often being either (a) traffic-controlled, or (b) on a timed cycle that favors one direction over another. That is, their probability of being green is very unlikely to be 1/2 in any sort of random way.
Answer:
<u><em>A-200 times spun</em></u>
<u><em>B-240 times spun</em></u>
<u><em>C-280 times spun</em></u>
<u><em>D-160 times spun</em></u>
<u><em>E-120 times spun</em></u>
Step-by-step explanation:
Step one. you need to find out what 1,000 divided by 50 is. You should get 20...
Step two. You need to multiply each of the spinner results by 20 to get your final prediction.
Then simplify!!
Answer:
y = -1/3x -2
Step-by-step explanation:
Slope intercept form of a line is
y= mx+b
We need to solve for y
1/3x +y = -2
Subtract 1/3x from each side
1/3x -1/3x +y =-1/3x -2
y = -1/3x -2
