The solution to the system of equations y = -2x + 4 and y = 1/2x + 4 is the point (0, 4)
A system of equations is a set of two or more equations that are to be solved simultaneously.
The solution of a system of equations is a set of values that satisfy all the equations in the system.
Given the equations:
y = -2x + 4
y = 1/2x + 4
The question implies that we solve graphically
So, we create a plot of the equations y = -2x + 4 and y = 1/2x + 4
And we write out the coordinate of the point of intersection between the two equations
From the graph of the system of equations (see attachment), we have the point of intersection to be (0, 4)
This means that the solution to the system of equations is (0, 4)

Step-by-step explanation:
The probability is ___. Round to four decimal places as needed.)
b. Calculate the probability that more than 30 errors will be found.
The probability is ___. (Round to four decimal places as needed.)
c. Find the probability that fewer than 15 errors will be found.
The probability is ___. (Round to four decimal places as needed.)
The probability that noerrors will be found is 0.
The probability of finding more than 30 errors is 0.0001.
The probability of finding fewer than 15 errors is 0.9452.
It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The number of errors in a 3,000-word passage follows a Poisson distribution with a mean of 12 errors.
i.e
Since 3,000 is six times 500.
a)
The probability that no errors will be found.
P(X = 0) = x / 0!
= 0.000006
Rounded to four decimal places.
= 0.0000.
b)
The probability of finding more than 30 errors.
P(X > 30) = 1 - P(X ≤ 30)
We can use a Poisson table.
P(X ≤ 30) = 0.9999.
P(X > 30) = 1 - 0.9999
= 0.0001
Rounded to four decimal places.
= 0.0001.
c)
The probability of finding fewer than 15 errors.
P(X < 15) = P(X <= 14)
= ∑(k=0 to 14) x / k!
From the Poissontable.
P(X ≤ 14) = 0.9452
P(X < 15) = P(X ≤ 14)
= 0.9452
Rounded to four decimal places.
= 0.9452.
Thus,
The probability that no errors will be found is 0.
The probability of finding more than 30 errors is 0.0001.
The probability of finding fewer than 15 errors is 0.9452.

Step-by-step explanation:
this is the answer of this question
The 6 in the tenths place in the number 51.66 is ten times greater in value than the 6 in the hundredths place, due to positional values in decimal numbers.
In the decimal number 51.66, the value of the 6 in the tenths place is indeed ten times the value of the 6 in the hundredths place. This is because each place to the right of the decimal point is ten times smaller than the place to its immediate left. Therefore, although both of these digits are 6, the 6 in the tenths place represents a value of 0.6 (or 6/10), whereas the 6 in the hundredths place represents a value of 0.06 (or 6/100). So, when you divide 0.6 by 0.06, you get 10, showing that the 6 in the tenths place is ten times the value of the 6 in the hundredths place.
