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.
Answer:
The answer to your question is:
a) V(12) = 1600
b) V(15) = 3200
Step-by-step explanation:
Data
V(t) = 100 2^(t/3)
Process
V(12) = 100 2^12/3
V(12) = 100 2^4
V(12) = 100 (16)
V(12) = 1600
V(15) = 100 2^(15/3)
V(15) = 100 2^5
V(15) = 100 32
V(15) = 3200
Step-by-step explanation:
Fraction of work done by Gardner in 1 hr = 1 / 5
Fraction of work done by Gardner and helper in 1 hr = 1 / 4
Fraction of work done by helper in 1 hr
= 1 / 4 - 1 / 5
= 1 / 20
<u>Time required by helper to complete work</u> :
= <u>20 hours</u>
Answer:
x=12
Step-by-step explanation:
10x-18+6x+6=180
16x-12=180
16x=180+12
16x=192
x=192/16
x=12
