Answer: see image

Step-by-step explanation:

Draw line x = -2. Count how many units away each point is from line x = -2 and create the new points the same number of units away from line x = -2 but in the opposite direction.

S is 5 units to the right of x = -2. The new point S' is 5 units to the left of x = -2.

T is 6 units to the right of x = -2. The new point T' is 6 units to the left of x = -2.

U is 6 units to the right of x = -2. The new point U' is 6 units to the left of x = -2.

V is 5 units to the right of x = -2. The new point V' is 5 units to the left of x = -2.

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

Sauron [17]

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

School rules permit no fewer than 2 teachers per 25 students. There are at least 245 students enrolled in the school. If x repre

NISA [10]

First, let's write down this inequality:
There are at least 245 students enrolled in the school.

y≥245

This inequality says what the sentence says!

now, the number of teachers must be:
x≥2*(y/25)
(two times the number of groups of students of 25!)

so those two inequalities, taken together will be the answer!
