Pls i'll will rate ! on the evening news, the meteorologist states that there is a 70% chance that it will rain the next morning. select all the statements that are true. it is neither unlikely nor likely that it will rain the next day. it is certain that it will rain the next day. it is likely that it will not rain the next day. it is unlikely that it will rain the next day. it is unlikely that it will not rain the next day. it is likely that it will rain the next day.

It is likely that it will rain the next day

It is Unlikely to rain the next day

∞ this is your sign

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
