Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27
Answer:
B
Step-by-step explanation:
you will multiply the exponents
The amount after 2 years is $2,295.
Given that,
- The invested amount is $1,240.
- The rate of interest is 8%.
- The number of years is 2 × 4 = 8
Based on the above information, the amount after 2 years is
Future value = Present value ×(1 + rate of interest)^number of years
= $1,240 × (1 + 0.08)^8
= $1,240 × 1.08^8
= $2,295
Therefore we can conclude that the amount after 2 years is $2,295.

Use the next formula to find the margin or error:
z is the critical value (For a 95% confidence level the z-score is 1.95998)
σ is the standard deviation
n is the sample size
<h2>Then the margin of error is: 6.6639</h2>
