Answer:
21: 35
Step-by-step explanation:
(1+R) to the power of n = A/P
(1+R) to the power of 4 = 3238.17/2600
(1+R) to the power of 4 = 1.245
(1+R) = 4 root 1.245
1+r = 1.05631
R = 0.05631
The interest rate percentage is 5.63% (2dp)
Answer:
<h2>x = 4</h2><h2>y = 3</h2>
Step-by-step explanation:
2x - 3y = - 1 ………… Equation 1
y = x - 1 ….……….… Equation 2
To solve using substitution , substitute equation 2 into equation 1
That's
2x - 3( x - 1) = - 1
2x - 3x + 3 = - 1
- x = - 1 - 3
- x = - 4
Multiply through by - 1
We have
<h3>x = 4</h3>
Substitute x = 4 , into y = x - 1
We have
y = 4 - 1
y = 3
We have the answers as
x = 4
y = 3
Hope this helps you
We are given the following data
n = 35
x = 50
s = 2
CI = 95% (z = 1.96)
The formula for the margin of error is
E = z s / √n
Substituting the given values
E = 1.96 (2) / √35)
E = 0.66 or 66%
100%/x%=125/55
(100/x)*x=(125/55)*x - we multiply both sides of the equation by x
100=2.27272727273*x - we divide both sides of the equation by (2.27272727273) to get x
100/2.27272727273=x
44=x
x=44 So your answer is 44 ^-^
