Let x be the normal distribution with mean μ=−19
μ
=
−
19
and variance 16
16

for some value of z
z
,

p(x> 3)=p(z> z),

(where z is the standard normal distribution).

find the exact value of z
z
. give your answer as a decimal (do not round) or as a fraction in a fully simplified form.

Idk idk idk idk idk idk idk idk idk

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

1+1=22×1=22-1=11-1=1duh
