Answer:
x=4 y=8
Step-by-step explanation:
y=2x
y=12-x
Substituiting y value from first equation into second equation.
2x=12-x
3x=12
x=4
y=2(4)=8
y=12-4=8
Answer:
36ft³
Step-by-step explanation:
Bottom rectangular prism: 2x2x6=24
Top rectangular prism: 2x2x3=12
24+12=36ft³
Answer:
- The graph cannot represent a normal density function because it is not symmetric.
Step-by-step explanation:
The second and third descriptions are false on their face: neither describes a characteristic of the graph shown. A normal distribution is symmetric about the mean; this graph is not symmetric, so cannot represent a normal distribution.
3√28=6√7 . 3√28 . √28=2√7 . 3·2√7 = 6√7
4√7+6√7 = 10√7
