#1: Find the value of X. (GEOMETRY)
1 answer:
Answer:
x = 14
Step-by-step explanation:
1. We know that all angle measures in a triangle sum to 180 degrees.
- This means that 7x - 11 + 5x - 2 + 2x - 3 = 180.
2. (Solving)
Step 1: Combine like terms.
Step 2: Add 16 to both sides.
Step 3: Divide both sides by 14.
Step 2: Check if solution is correct.
Therefore, the answer is x = 14.

The correct answer is the first choice, ($1818.30, $5077.70.)
To find this, we first find the z-score based on the confidence level:
Convert 95% to a decimal: 95%=95/100 = 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1-0.025 = 0.975
Using a z-table (http://www.z-table.com) we see that this value is associated with a z-score of 1.96.
Next, we identify
Next we find
Next we find
Next, we multiply this value by z:
1.96(831.479) = 1629.70
The confidence interval is given by
