A sequence is said to be arithmetic if every couple of adjacent elements differ by the same number. If this is the case, that constant number is called the common difference.
This sequence is arithmetic, because the difference between every element and the previous one is
So, the common differnece is 3.4, because every couple of adjacent terms differ by 3.4
Answer:
The probability of finding the white ball from second Jar = 20/39
Step-by-step explanation:
Jar 1 contains 1 White ball and 4 black balls
P(w | J₁) = 1/5
Jar 2 contains 2 White balls and 1 black ball
P(w | J₂) = 2/3
Jar 1 contains 2 White balls and 1 black ball
P(w | J₃) = 2/3
Also, Given
P(J₁) = 1/2
P(J₂) = 1/3
P(J₃) = 1/6
P(w) = P(J₁)×P(w | J₁) + P(J₂)×P(w | J₂) + P(J₃)×P(w | J₃)
P(w) = 1/2×1/5 + 1/3×2/3 + 1/6×2/3 =13/30
To find: P(J₂ | w)
According to conditional probability,
P(J₂ | w) = P(J₂)×P(w | J₂)/P(w)
P(J₂ | w) = (1/3×2/3)/(13/30)
P(J₂ | w) = (1/3×2/3)/(13/30) = 20/39
<u>The probability of finding the white ball from second Jar = 20/39</u>
I think the answer is 30
Because I did 150÷500×100
Answer:
Step-by-step explanation:
7) m + 6 > 17
m > 17- 6
8. 500 + p > 1500
9. Let cost of pencil be 'x' and it is 5 less than y
x < y -5
Cost of pencil and ruler is less than $ 30.
x + y < 30
10. r + 5 > 17
r > 17 - 5
r > 12
12.She is spending $ x. So, we have to subtract from $10.
10 -x < 5
