Step-by-step explanation:
<span>Polly uses a probability simulator to pull colored ribbons from a bag 60 times and to flip a coin 60 times. The results are shown in the tables below:
</span>
<span><span>Color of RibbonNumber of Times Pulled</span><span><span>White25</span><span>Green14</span><span>Orange21</span></span></span>
<span><span>HeadsTails</span><span>3822</span></span>
<span>Using Polly's simulation, what is the probability of pulling an orange ribbon and the coin landing on tails?</span>

Answer:
(1, 2 )
Step-by-step explanation:
x + y = 3 (subtract x from both sides )
y = 3 - x → (1)
2x - y = 0 → (2)
Substitute y = 3 - x into (2)
2x - (3 - x) = 0
2x - 3 + x = 0
3x - 3 = 0 ( add 3 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into (1)
y = 3 - 1 = 2
solution is (1, 2 )
<u>Answer:</u>
-
The length of the hypotenuse is 40 mm.
<u>Step-by-step explanation:</u>
<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>
-
10² = 5² + a²
- => 100 = 25 + a²
- => a² = 75
- => a = 8.660
- => a = 8.7
Hence, the length of the hypotenuse is 8.7 m.
Hoped this helped.
