Answer:
z = - .5
Step-by-step explanation:
z = (x - μ)/ σ
z = 56 - 60/8 = -.5
Answer:
-20
Step-by-step explanation:
-Follow PEMDAS.
-2 negatives equal a positive.
-6 + 54/(-9) - 5 - 3
-6 + (-6) - 5 - 3
-12 - 5 - 3
-20
Answer:
1. C points radially outward from origin
2. A. Points radially outward from z origin
3. D. Radially inwards toward origin
4. B. Inwards towards the z axis
Step-by-step explanation:
1.
X²+y²+z² = f(x,y,z)
Vector P<x,y,z>
2<x,y,z> = 2p
The answer is c points radially outward from origin
2.
X²+y² = f(x,y)
<2x,2y,0>
Points radially outward from z axis
3.
D. Points radially inwards toward origin
4.
B. Points radially inwards toward the z axis.
