Answer:
60/30
Step-by-step explanation:
2 can be written as the rational number .
We want a denominator of 30, so we multiply the denominator by 30. However, we realize that if we only multiply the denominator by 30, we change the whole number from 2 into 2/30, which are obviously not the same. So, we have to multiply both the numerator and denominator by 30:
Thus, the answer is 60/30.
Hope this helps!
Answer:
The answer is 0.3629
Step-by-step explanation:
Let E represent the elder bridge
Let Y represent the younger bridge
Let A represent the ancient bridge
The chance that the elder bridge will collapse next year is 16%
Pr(E) = 16%
= 0.16
The chance that the elder bridge will not collapse next year is Pr(E')
Pr(E')= 1 – 0.16
= 0.84
The chance that the younger bridge will collapse next year is 4%
Pr(Y) = 4%
= 0.04
The chance that the younger bridge will not collapse next year is Pr(Y')
Pr(Y')= 1 – 0.04
= 0.96
The chance that the ancient bridge will collapse next year is 21%
Pr(A) = 21%
= 0.21
The chance that the ancient bridge will not collapse next year is Pr(A')
Pr(A')= 1 – 0.21
= 0.79
The probability that exactly one of the bridge s will collapse next year is
1 – (Pr(E') n Pr(Y') n Pr(A'))
= 1 – (0.84*0.96*0.79)
= 1 – 0.637056
= 0.362944
= 0.3629(to 4 decimal place)

Step-by-step explanation
this is where i pretend to explain so i can get more points ;)
Since the cube root of 27 is 3, we have 3*27^(2/3). Next, something to the power of 2/3 means you square the cube root of it. Since the cube root is 3, we square that to get 9. After that, we get 3*9=27
