To solve what you need to do is
if y=x+4
and y=-x+2 so both equations have to equal the same thin so
x+4=-x+2
combine like terms and you get x=-x-2
then next equals 2x=-2
divide by 2 and last you get x=-1

To solve for the variables y and x we substitute the second equation into the first meaning that y = -x +2 you substitute y for (-x+2)
so

(-x +2) = x +4
add x to both sides
2 = 2x + 4
subtract 4 from both sides
-2 = 2x
divide by 2
-1 = x

now plug x back into the original equation

y = (-1) + 4
y = 3

and

y = -(-1) + 2
y = 1 +2
y = 3

there you have it x = -1 and y = 3

Hope this helps ;)

Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

Explanation:-

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-

when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be small, large but finite or infinite.

Example :- 1

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are finite number of observations.

Example :- 2

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

Population:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the population

The number of observations in the population is defined to be the size of the population.

Example :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

Sample:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population

A 12-foot flagpole casts a nine-foot shadow. What is the measure from the top of the shadow to the top of the flag pole?

Here is the answer OwO:

A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.

Here is the explanation/work OwO:

Switch sides.

c^2=12^2+9^2

12^2=144

c^2=144+9^2

9^2=81

c^2=144+81

Add the numbers: 144 + 81 = 225

c^2=225

For x^2 = f(a) the solution is √f(a)

c = 15

Therefore, your answer will be 15.
