Formular is (principal *time*rate )/100 +principal
so applying that we have( 2000*5*7) +2000 which gives 2700 dollarss
Answer:
The value of the constant in the equation below is 20.
Step-by-step explanation:
You are given the formula height = constant/width. All you have to do is take one of the points given on the graph and plug it in to the formula.
Example:
1 = Constant/20
Constant = 20
Answer:
I am not sure but for
CAE it is 65˚
CBD it is 65˚
Step-by-step explanation:
x+40=3x-10
Move the 3x to the other side by subtracting by 3x on both sides
x-3x+40=3x-3x-10
The equation now looks like this:
-2x+40=-10
Move 40 to the other side by subtracting 40 both sides:
-2x+40-40=-10-40
-2x=-50
Divide by -2 on both sides:
-2x/-2=-50/-2
x=25
Since we found out what x is we can replace x in both CAE and CBD:
For CBD: 25+40 is 65
For CAE: 3(25)-10 is 65
By the formula for the area of an equilateral triangle (s^2sqrt(3)/4), the area is sqrt(3)/4.
Answer:
465
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
Assuming 95% confidence, CV = z = 1.96.
Standard error is:
SE = σ / √n
SE = 3.3 / √n
Given margin of error of 0.3:
0.3 = 1.96 × 3.3 / √n
n = 465
