What is the Percentage area of 2.6 standard deviation

1 answer:

6 0

Please try to be more specific. What I think you meant was "what is the area under the standard normal curve to the left of 2.6 standard deviations above the mean?" If that's it, the area can be found from a table of z-scores (look for z=2.6) or by using a calculator:

normalcdf(-100,2.6) = 0.995.

Which ordered pair is a solution of this

natali 33 [55]

Answer:

(- 3, 2 )

Step-by-step explanation:

To determine which ordered pair is a solution, substitute the x and y- coordinates of the given points into the left side of the equation.

If the result is equal to the right side then the pair is a solution.

(2, - 2)

- 6(2) - 7(- 2) = - 12 + 14 = 2 ≠ 4 ← not a solution

(- 2, 2 )

- 6(- 2) - 7(2) = 12 - 14 = - 2 ≠ 4 ← not a solution

(- 3, 2 )

- 6(- 3) - 7(2) = 18 - 14 = 4 = right side ← a solution

(2, - 3 )

- 6(2) - 7(- 3) = - 12 + 21 = 9 ≠ 4 ← not a solution

(- 3,2 ) is a solution of the equation
