Answer:
−4x2−2
Step-by-step explanation:
Answer is $23.76
Calculate 20% of 22 and add it to 22:
20% x 22 = 4.4
22 + 4.4 = $26.4
Calculate 10% of 26.4 and subtract from 26.4
10% x 26.4 = 2.64
26.4 - 2.64 = $23.76
Answer: Option E is the correct answer; (1 + p⁴) / (1 + p³)
Step-by-step explanation:
P (3 head) = P(first and 3 heads) + P(second coin and 3 heads)
= (1/2)×1³ + (1/2)× p³ = (1/2) × (1 + p³)
therefore P(first coin given 3 heads) = (1/2)×1³/ ((1/2)×(1 + p³))
= 1 / (1 + p³)
Also P( second coin given 3 heads) = p³ /(1 + p³)
therefore P(4th toss in heads given first 3 are heads) will be;
= P(first and 4th toss heads) + P(second and 4th toss heads)
=(1/( 1 + p³ )) × 1 + p³ / (1+p³) × p
= (1 + p⁴) / (1 + p³)
Therefore Option E is the correct answer
Answer:
1 9/40
Step-by-step explanation:
Any calculator can tell you the sum is ...
1 + 2/16 + 0.6 - 1/2 = 1.225
The decimal fraction can be reduced, if you like:
225/1000 = (25)(9)/(25(40)) = 9/40
As a mixed number, the sum is 1 9/40.

Alternate solution
1 2/16 + 0.6 -1/2 = 1 1/8 + (6/10 -5/10) = 1 1/8 + 1/10
= 1 + (1/8 +1/10) = 1 +(5/40 +4/40) = 1 9/40
