Answer:
1/2
Step-by-step explanation:
x + 9 = -15x = [1]
x - x + 9 = -15x -x = 1 
9 - 1 = -16x
8 = 16x
8/16 = 16/16x
1/2 = x

His commission would be 111,000.
You can get this answer by multiplying 6% times 1,850,000. This would get you the answer of 111,000.
Hope this helps! I would greatly appreciate a brainliest! :)
        
             
        
        
        
Answer: 916. Because if you do 856+60=916.
Step-by-step explanation: The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1. Formula: and natural statistics x and x2. The dual expectation parameters for normal distribution are η1 = μ and η2 = μ2 + σ2.
 
        
             
        
        
        
<span>The <u>correct answer</u> is: 
576 sq. cm. 
Explanation: 
The surface area of a figure is the sum of the areas of the faces of the figure. 
The slant height goes from the apex of the pyramid along a face and is perpendicular to the base at the bottom of that face. This gives us 2 measurements of each triangular face of the pyramid: the height (the slant height of the pyramid is the height of the triangular face), 18 cm, and the base <span>of the triangular face, 12 cm. 
The formula for the area of a triangle is A = 1/2bh; using our measurements we have: 
A = 1/2(12)(18) = 108 sq. cm. 
There are 4 triangular faces on a square pyramid, and each will have an area of 108 sq. cm.; this gives us: 
4(108) = 432 sq. cm. 
The area of the base is given by length times width, or 12*12 = 144 sq. cm. 
This gives us a total surface area of 432+144=576 sq. cm.</span></span>
