A certain spinner has equally sized slices. The probability of landing on a red slice is 4/9. What are the odds in favor of land
Novosadov [1.4K]
There are 4 red slices out of 9 total. So there are 9-4 = 5 slices that are not red. The odds in favor of landing on red is 4:5

We basically write the number of ways to get what we want (4), followed by a colon, then the second number is the number of ways to get what we don't want (anything but red; 5 ways)

So that's why the answer is 4:5

-----------------------------------

Side Note -- If we want the odds against, we simply flip the ratio. The odds against would be 5:4 because there are 5 ways to lose and 4 ways to win. This is assuming that landing on red means you win.

100 POINS, Help

Answer: Translate triangle ABC so that point B lies on point D to confirm ∠B ≅ ∠D.

Step-by-step explanation: Since we already know that angle A is congruent to itself by the reflexive property, all we need is another pair of corresponding angles to be congruent according to the AA (angle-angle) similarity postulate. This postulate states that; If two corresponding angles of two or more triangles are congruent, the triangles are similar. So when we translate triangle ABC so that point ∠B lies on ∠D, we prove that these two angles are congruent.

I also got it right on the test. So... yeah.

hope this helps dood.

what is the order from least to greatest - 4 with the exponent of 3, square root of 40, square root of 13, square root of 7, , 1
LuckyWell [14K]

Answer: -4^{3} , 14/9 , \sqrt{7} , \sqrt{13} , \sqrt{40}

Step-by-step explanation:

-4^{3} = - 64

\sqrt{40} = 6.32455532

\sqrt{13} = 3.605551275

\sqrt{7} = 2.645751311

14/9  = 1.555555556

Arranging from least to greatest , we have :

-4^{3} , 14/9 , \sqrt{7} , \sqrt{13} , \sqrt{40}
