No, it is not. If you see closely, the number 5.2 is not 52. 60 is greater than 5.2.
They are equivalent
30:12 => 5:2
40:16 => 5:2
hope this helsp
To get the probability that at least 8 of the words on the test are words that students know we need to do the following calculations.
<span>=[C(16,8)*C(10,2) + C(16,9)*C(10,1) + C(16,10)*C(10,0)] / C(26,10)
</span>
=0.132
1/2 as a decimal is .5 ( it means .50) hoped it helped
1/2 + 3/4 =
1/2 = 2/4
2/4 + 3/4 = 5/4 = 1 1/4
Answer = 1 1/4
Hope this helped☺☺
