Answer:
Step-by-step explanation:
Given: Principal or P .
Rate or R per annum compounded annually.
Time or T years.
To find: Percentage difference between compound interest of first year and second year.
Solution:
First year interest .
First year amount .
For the second year, the interest is compounded semi-annually.
So, time is doubled and the rate is halved.
Second year compounded amount .
Second year compound interest .
Difference in interest of first and second year .
Percentage difference .
Hence, the percentage difference between compound interest of first year and second year is .

The Vertex of the parabola is V=(-5,-2)=(h,k)→h=-5, k=-2
This is a vertical parabola, then its equation has the form:
y=a(x-h)^2+k
Relacing h=-5 and k=-2
y=a(x-(-5))^2+(-2)
y=a(x+5)^2-2
When the x-value is -4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation:
a=?
x=-4, y=2→2=a(-4+5)^2-2
2=a(1)^2-2
2=a(1)-2
2=a-2
2+2=a-2+2
4=a
a=4
Answer: The coefficient of the squared expression in the parabola's equation is 4
Answer: Option B. 4
A goes to 1
B goes to 4
C goes to 3
D goes to 2
Answer:
The expected number of bowerbirds in the sample that will have bower featuring reflective color is E(X)=0.9
Step-by-step explanation:
We can model this with a binomial random variable, with sample size n=3 and probability of success p=0.3.
The expected number of bowerbirds in the sample that will have bower featuring reflective color can be calculated as:
