Answer:
-4.5
Step-by-step explanation:
15(2-x)=13(3-x)
Expand parentheses:
30-15x=39-13x
Add 15x to both sides:
30=2x+39
Subtract 39 from both sides:
2x=-9
Divide both sides by 2:
x=-4.5
Hope this helps!
Answer:
Option C. \frac{5}{8} is the correct option.
Step-by-step explanation:
In the given question numbers marked on a spinner are given = 8
Out of these numbers marked on spinner number of vowels are = 3
Therefore the sample set n(S) is = 8
and the favorable events are n(E) = 3.
As per rules of the probability, the probability of spinning the spinner and landing on vowel will be = \frac{n(E)}{n(S)}=\frac{3}{8}
Now probability of spinning the spinner and not landing on a vowel will be
P(E)' = 1-\frac{3}{8}=\frac{5}{8}
Option C. \frac{5}{8} is the answer.
