647474 is the answer it’s for sure right i had the same problem
Let P be the plane that intersects
- x-axis at point (-5,0,0);
- y-axis at point (0,-2,0);
- z-axis at point (0,0,5).
Write the equation of the plane P:

Then

The coefficients at variables x, y and z are the coordinates of perpendicular vector to the plane. Thus

Answer: 
Tetrahedron - its the only one that has a base from which all edges meet at a single point.
Answer:
The minimum sample needed to provide a margin of error of 3 or less is 52.
Step-by-step explanation:
The confidence interval for population mean (<em>μ</em>) is:

The margin of error is:

<u>Given:</u>
MOE = 3
<em>σ </em>= 11
The critical value for 95% confidence interval is: 
**Use the <em>z</em>-table for critical values.
Compute the sample size (<em>n</em>) as follows:

Thus, the minimum sample needed to provide a margin of error of 3 or less is 52.
