If BA and AC are vectors then AB= (-4 3)
Then B is at (3 - 4, -2 + 3) = (-1, 1)
and C is at (3 + 4, -2 + 9) = (7, 7)
We can write this as :
1/3 x 2 or 2/1
Answer:
1/8
Step-by-step explanation:
simplify
4^(-3/2)
= 1/4^(3/2)
= 1/[(2²)^(½)]³
= 1/[2]³
= 1/8

Answer:
0.1190
Step-by-step explanation:
If z = -1.18, the total area to the left under the standard normal curve is taken from the z-distribution table attached;
P(z < - 1.18) = 0.1190
Also, to the right of z = 1.18, we have;
P(z > 1.18) = 1 - P(z < 1.18)
From the second image attached from z-table, we have;
P(z > 1.18) = 1 - 0.8810
P(z > 1.18) = 0.1190
Thus, the total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is 0.1190
