A system of equations is shown below 5x +2y =-15 2x - 2y =-6 what is the solution to the problem

Citrus2011 [14]

Answer:

(-3, 0)

Step-by-step explanation:

Let's solve this system using the elimination by addition/subtraction method. Begin by writing the two equations one above the other:

5x +2y =-15

2x - 2y =-6

Notice that the y terms cancel each other out:

5x +2y =-15

2x - 2y =-6

------------------

7x = -21

Dividing both sides by 7 results in x = -3.

Subbing -3 for x in either of the given equations leads to finding y:

5(-3) + 2y = -15, or -15 + 2y = -15. This results in 2y = 0, or y = 0.

The solution is (-3, 0).

Answer:

The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the $\frac{Rise}{Run}$ technique. Moving up 2 units and to the right 1 unit, which would be represented by $\frac{2}{1}$ .

At Denver International Airport, 86% of recent flights have arrived on time. A sample of 11 flights is studied. What is the vari

notsponge [240]

Answer:

$s^2=1.32$

Step-by-step explanation:

-This is a binomial probability distribution problem.

-Given that p=0.86 and n=11, the sample variance can be calculated using the formula:

$\sigma^2=np(1-p)$

#We substitute the given parameters in the formula to solve for variance:

$\sigma^2=np(1-p)\\\\\\=11\times 0.86(1-0.86)\\\\=1.324\approx1.32$

Hence, the sample variance is 1.32
