This is the concept of statistics, to solve the question we proceed as follows;
We need to standardize our values;
z(3,875)=(3,875-4000)/42
z(3,875)=-2.9762
z(4055)=(4055-4000)/42=1.3095=1.3
Therefore;
p(3875<x<4055)
=p(-3<z<1)
=0.9034
The correct answer is D]
Answer:
$280.51
Step-by-step explanation:
The formula we want to use:
where:
P is the principal
r is the the rate
n is the number of compounding per year
t is total number of years
A is the ending amount
We are given P=200, r=.07, n=1 (compounded once a year), t=5.
So plugging this in:
Simplify a little:
Just a little more:
Now I'm going to put the rest of this in the calculator:
200*(1.07)^5 is what I'm putting in my calculator.
This is approximately 280.5103461.
To the nearest cent this is 280.51

Answer:
x=−1 or x=−6
Step-by-step explanation:
Multiply all terms by x and cancel:
xx+6=−7x
x2+6=−7x(Simplify both sides of the equation)
x2+6−−7x=−7x−−7x(Subtract -7x from both sides)
x2+7x+6=0
(x+1)(x+6)=0(Factor left side of equation)
x+1=0 or x+6=0(Set factors equal to 0)
x=−1 or x=−6
Check answers. (Plug them in to make sure they work.)
x=−1(Works in original equation)
x=−6(Works in original equation)
