Answer:
Although I'm not entirely sure of the question (sorry lol), any ratio that is 1.5:2 , 6:8 , 9:12 , 12:18 etc would be equivalent to 3 to 4.
Step-by-step explanation:
If you divide both 3 and 4 by 2 you'd wind up with 1.5 ( 3 ) and 2 ( 4 ). When multiplying, you'd get 3x2 = 6 and 4x2=8, 3x3 = 9 and 4x3 = 12 and so on.
Alright, so I=prt. I is 1090-900=190=interest. It starts at 900, so that is p. R is 0.09. 1090=900*0.09*t, so 1090/(900*0.09)=t=around 13 years
Answer:
The probability that R2 is bigger than R1 is P=0.9633.
Step-by-step explanation:
We need to compute the probability that R2 is bigger than R1:

To do this, we define a new variable Das the difference between the two resistances:

Then,

As R1 and R2 are normal random variables, the properties of D are:

Then, we can calculate the z-value for D=0


B = 1/4c + 14
d = 5/4c - 2
b = d
1/4c + 14 = 5/4c - 2 ....multiply by 4
c + 56 = 5c - 8
56 + 8 = 5c - c
64 = 4c
64/4 = c
16 = c <== Chris
b = 1/4c + 14.....b = 1/4(16) + 14.....b = 4 + 14....b = 18 <== Brian
d = 5/4c - 2....d = 5/4(16) - 2.....d = 20 - 2.....d = 18 <== Damien
solution : Brain and Damien answered 2 more questions correctly then Chris did. <===
