Answer:

the system of equation has infinite solution

Step-by-step explanation:

5x_1 + x_2 = 0 , 25x_1 + 5x_2 = 0

Solve the first equation for x_2

Subtract 5x1 on both sides

5x_1 + x_2 = 0

x_2 =-5x_1

Now substitute -5x1 on second equation

25x_1 + 5x_2 = 0

25x_1 + 5(-5x_1)= 0

25x_1-25x_1= 0

0=0

So the system of equation has infinite solution

Answer:

Step-by-step explanation:

The system of linear equations is expressed as

5x1 + x2 = 0 - - - - - - - - - - - 1

25x1 + 5x2 = 0 - - - - - - - - - - 2

The first step is to eliminate x2 by multiplying equation 1 by 5 and equation 2 by 1. It becomes

25x1 + 5x2 = 0

25x1 + 5x2 = 0

The next step is to subtract equation 2 from equation 1, it becomes

25x1 - 25x1 + 5x2 - 5x2 = 0

0 = 0

The system of equations has an infinite number of solutions. This means that for as many values of x that satisfies equation 1, they will also satisfy equation 2.

Answer:

E

Step-by-step explanation:

let a, b, c represent the number of students in 6th, 7th, 8th grade

ratio of students : teachers = 28 : 1

There are 82 teachers , so 28 × 82 = 2296 students

Then

a + b + c = 2296 , that is

828 + b + c = 2296 ( subtract 828 from both sides )

b + c = 1468 → E

Let X be a discrete random variable with geometric distribution.
 Let x be the number of tests and p the probability of success in each trial, then the probability distribution is:
 P (X = x) = p * (1-p) ^ (x-1). With x = (1, 2, 3 ... n).
 This function measures the probability P of obtaining the first success at the x attempt.
 We need to know the probability of obtaining the first success at the third trial.
  Where a success is defined as a customer buying online.
 The probability of success in each trial is p = 0.3.
 So:
 P (X = 3) = 0.3 * (1-0.3) ^ (3-1)
 P (X = 3) = 0.147
 The probability of obtaining the first success at the third trial is 14.7%
