Step-by-step explanation:

You ask a neighbor to water a sickly plant while you are on vacation. Without water the plant will die with probability 0.7. With water it will die with probability 0.4. You are 86 % certain the neighbor will remember to water the plant.

Prob for plant dying with water = prob that he waters but plant dies

= 0.86*0.4

= 0.344

Prob for plant dying without water = prob that he does not water and the plant dies

= (1-0.86)*0.7

= 0.098

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
