Answer: 5% interest rate
==============================================
Work Shown:
The given values are
A = 5205.75
P = 3500
n = 4
t = 8
-----
Plug those values in. Isolate r.
A = P*(1+r/n)^(n*t)
5205.75 = 3500*(1+r/4)^(4*8)
5205.75 = 3500*(1+r/4)^(32)
3500*(1+r/4)^(32) = 5205.75
(1+r/4)^(32) = 5205.75/3500
(1+r/4)^(32) = 1.48735714285714
1+r/4 = (1.48735714285714)^(1/32)
1+r/4 = 1.01248355256014
r/4 = 1.01248355256014-1
r/4 = 0.01248355256014
r = 4*0.01248355256014
r = 0.04993421024056
r = 0.0499
Multiply this r value by 100 to convert to a percentage
100*r = 100*0.0499
100*r = 4.99%
Rounding to the nearest tenth, we get 5.0% or just 5%
Answer:
2.15
Step-by-step explanation:
The easiest way to convert a percentage to a decimal is to simply add a decimal on the number (If the number does not already have one), then move that decimal two places to the left.
We can do that like so:
1: Remove the percentage sign: 215% -> 215
2: Add a decimal at the end of the number: 215.
3: Move the decimal two places to the left: 2.15
<em>So 215% converted to a decimal would be 2.15</em>
Answer:
The weight corresponding to which weight will be larger than 14% of times equals 427.635 grams.
Step-by-step explanation:
We need to find the value of weight that corresponds to 14% of area under the normal distribution curve
It is given that
Using standard normal distribution tables we find value of Z corresponding to 14% of the area as -1.080
Thus using the standard equation
Answer:
x = 4. (Answer B)
Step-by-step explanation:
Combine the x-terms on the left side: -x + 3x = 2 + 6.
Simplifying further, 2x = 8, or x = 4. (Answer B)
3.5 , 19/5 , 4.1 , 2(square root)15
