Answer:
26% probability that they win both contracts.
Step-by-step explanation:
These following probabilities are important to solve this question:
0.4 = 40% probability of winning the first contract.
0.65 = 65% probability of winning the second contract if the first contract is won.
What is the probability that they win both contracts?
26% probability that they win both contracts.
Answer:
The accumulated amount after 4 years is $1280.
Step-by-step explanation:
Principal = $1000
Time = 4 years
Rate of Interest = 7%
SIMPLE INTEREST =
⇒SI =
or, the amount of simple Interest = $280
Now, Accumulated Amount = Principal Amount + Simple Interest
= $1000 + $280
= $1280
Hence, the accumulated amount after 4 years is $1280.
Answer:
{x = 1/7
,y = 1
Step-by-step explanation:
Solve the following system:
{-5 y = -5 | (equation 1)
{7 x + 6 y = 7 | (equation 2)
Swap equation 1 with equation 2:
{7 x + 6 y = 7 | (equation 1)
{0 x - 5 y = -5 | (equation 2)
Divide equation 2 by -5:
{7 x + 6 y = 7 | (equation 1)
{0 x+y = 1 | (equation 2)
Subtract 6 × (equation 2) from equation 1:
{7 x+0 y = 1 | (equation 1)
{0 x+y = 1 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 1/7 | (equation 1)
{0 x+y = 1 | (equation 2)
Collect results: Answer: {x = 1/7
,y = 1
