The solution to 6×+2y=6 is y=0.5

The solution for 7×+3y=5 is y =  0.238095 (.238095 is repeated)

The solution if it’s to find the value of X and Y
Get one variable by itself
2y=6-6X
Divide by 2
Y=3-3x
Then substitute y for 3-3x
7x+3(3-3x)=5
7x+9-9x=5
-2x+9=5
Subtract 9 from each side
-2x=-4
Divide by -2 on each side
X=2 then plug x for 2
7(2)+3y=5
14+3y=5
Subtract 14 on each side
3y=-9
Divide by 3 on each side
Y=-3

X=2 Y=-3

Using a number cube and this hat with 5 different-colored marbles, which simulation would help you answer this question? During
Arlecino [84]

Answer:

  see the attachment

Step-by-step explanation:

We assume that the question is interested in the probability that a randomly chosen class is a Friday class with a lab experiment (2/15). That is somewhat different from the probability that a lab experiment is conducted on a Friday (2/3).

Based on our assumption, we want to create a simulation that includes a 1/5 chance of the day being a Friday, along with a 2/3 chance that the class has a lab experiment on whatever day it is.

That simulation can consist of choosing 1 of 5 differently-colored marbles, and rolling a 6-sided die with 2/3 of the numbers being designated as representing a lab-experiment day. (The marble must be replaced and the marbles stirred for the next trial.) For our purpose, we can designate the yellow marble as "Friday", and numbers greater than 2 as "lab-experiment".

The simulation of 70 different choices of a random class is shown in the attachment.

<em>Comment on the question</em>

IMO, the use of <em>70 trials</em> is coincidentally the same number as the first <em>70 days</em> of school. The calendar is deterministic, so there will be exactly 14 Fridays in that period. If, in 70 draws, you get 16 yellow marbles, you cannot say, "the probability of a Friday is 16/70." You need to be very careful to properly state the question you're trying to answer.

What is a function that converts an input of letters and numbers into an encrypted output of a fixed length
nika2105 [10]

The function that converts an input of letters and numbers into an encrypted output of a fixed length is the hash function

<h3>How to determine the function?</h3>

From the question, we have the following highlights:

  • The inputs are letters and numbers
  • These inputs are converted and encrypted
  • The output has a fixed length

The mathematical function with the above features is a hash function

Hence, the function is the hash function
