Nonparametric tests are also called distribution-free tests because they don't assume that your data follow a specific distribution. You may have heard that you should use nonparametric tests when your data don't meet the assumptions of the parametric test, especially the assumption about normally distributed data.

URGENTLY NEED THIS ASAP PLZ TYSM
Kazeer [188]

Answer:

fifth option

Step-by-step explanation:

Given

- 2(x - 5) ≤ 6x + 18 ← distribute left side

- 2x + 10 ≤ 6x + 18 ( subtract 6x from both sides )

- 8x + 10 ≤ 18 ( subtract 10 from both sides )

- 8x ≤ 8

Divide both sides by - 8, reversing the sign as a result of dividing by a negative quantity, thus

x ≥ - 1

Please help i need this as soon as possible
masya89 [10]
It's a quadratic so the parent function will be
y = x ^{2}
We can see that it has been shifted to the right 5 units, which gives us a new function
y = (x - 5) ^{2}
It has also been shifted up 9 units:
y = (x - 5) ^{2}  + 9
But it has also been flipped across the y-axis which makes this the final change we need to do:
y =  - (x - 5) ^{2}  + 9
