<h3>Way to do</h3>
a. 17 out of 85 how many percentage?
b. what is 17% of 90?
- ? /90 × 100 = 17
- ? /90 = 17 : 100
- ? /90 = 0.17
- ? = 90 × 0.17
- ? = 15.3
c. 1026 out of ? = 54%
- 1026/? × 100 = 54
- 1026/? = 0.54
- ? = 1026 : 0.54
- ? = 1900
d. 8.1% of 90 = ?
e. ?% of 50 = 90
- 50 × ?/100 = 90
- ?/100 = 90:50
- ?/100 = 9/5
- ? = 9/5 × 100
- ? = 180
f. 88% of ? = 154
- ? × 88/100 = 154
- ? = 154 : 88/100
- ? = 175

You multiply by 10 or more
Answer:
P(R) = (18/38)
P(G) = (2/38)
P(B) = (18/38)
Step-by-step explanation:
Each spin is independent of the others, so the probabilities of the three possible outcomes (R,G,B) for each spin are:
P(R) = (18/38)
P(G) = (2/38)
P(B) = (18/38)
3/5
Because 40/100 simplifies to 2/5 and 2/10 simplies to 1/5
1/5 + 2/5 = 3/5
Answer:
x+2
Step-by-step explanation:
The firs 3 observations are x, x+2, x+4
Mean = sum of data/samaple size
Mean = x+x+2+x+4/3
MEan = 3x+6/3
Mean = 3(x+2)/3
Mean = x+2
Hence the required mean is x+2
