For this case we have the following system of equations:
We multiply the first equation by -4:
We have the following equivalent system of equations:
We add the equations:
We find the value of the variable "x":
Thus, the solution of the system is:

Answer:
1.0 N
Step-by-step explanation:
When the length increases by the factor 120/80 = 3/2, the force required is multiplied by the inverse of this: 2/3.
The required force is ...
(2/3)(1.5 N) = 1.0 N
If the ratio from Kala to Rose is 4:1, then for the 48 words Rose typed Kala typed 192 words. 48*4=192
Then Lita types twice as fast so 192*2=384.
It should be 384 words.
Answer:
Hence, the probability of exactly 3 successes in 6 trials of a binomial experiment round to the nearest tenth of a percent is:
31.2%
Step-by-step explanation:
The probability of getting exactly k successes in n trials is given by the probability mass function:
Where p denotes the probability of success.
We are given that the probability of success if 50%.
i.e.
also form the question we have:
k=3 and n=6.
Hence the probability of exactly 3 successes in 6 trials is:
Hence,
In percentage the probability will be:
Answer:
254 x 10^5
