Set up two equations
43.5 = 12x + 9y
51.5 = 8x + 15y
Solve
x = 1.75
y = 2.5
Answer:
Step-by-step explanation:
The approximate learning percentage can be estimated by using a doubling method.
If we breakdown the repetitions into three consecutive parts, we have:
1 - 2
2 - 4
3 - 6
then
1 - 2 → 46P = 39
P =39/46
P = 0.8478
P = 84.8%
2 - 4 → 39P = 33
P = 33/39
P = 0.84615
P = 84.6%
3 - 6 → 35P = 30
P = 30/35
P = 0.8571
P = 85.7%
The average value of P = (84.8 + 84.6 + 85.7)/3 = 85.03%
85%
From the tables of Learning Curves coefficient
The values are likened against times derived from 85% table factors at T = 46
Unit 1 2 3 4 5 6
Date 46 39 35 33 32 30
Computed - 39.1 35.56 33.26 31.56 30.22
b. Using your answer from part a, estimate the average completion time per repetition assuming a total of 30 repetitions are planned. (Round your answer to 3 decimal places.)
The average completion time =
At the total time factor 30, from the learning curves table , n(30) = 17.091
Thus:
The average completion time =
The average completion time =
The average completion time =
Answer:
D
Step-by-step explanation:
When you put the equation into the calculator.... the results are infinitely many solutions.
Answer:week 3 and week 1
Step-by-step explanation:
If there are x red marbles initially then 1/5 is a probability in it's lowest form cancelled down from:
<span>1/5 = x/5x </span>
<span>so there are 5x total marbles, x red and 4x blue. </span>
<span>Add 5 new red and the new probability is: </span>
<span>(x+5)/(5x+5) = 1/3 </span>
<span>3x+15 = 5x+5 </span>
<span>2x = 10 </span>
<span>originally there were: </span>
<span>x = 5 red </span>
<span>4x = 20 blue </span>
<span>marbles. </span>
<span>*************** </span>
<span>there are now: </span>
<span>x+5 = 10 red </span>
<span>4x = 20 blue </span>
<span>marbles.
hope it helps</span>
