Answer:
If anders flips one coin, he has a 1/2 chance of heads.
if he flips two, he has to get to heads, which the chances are 1/2 and 1/2
So multiply 1/2*1/2
you get 1/4
The formula of the future value of annuity ordinary
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value
Pmt payment
R interest rate 0.0425
K compounded monthly 12
N time 10 years
If the payment 150
Fv=150×(((1+0.0425÷12)^(12
×10)−1)÷(0.0425÷12))
=22,381.089
If the payment 200
Fv=200×(((1+0.0425÷12)^(12
×10)−1)÷(0.0425÷12))
=29,841.452
How much more
29,841.45−22,381.09
=7,460.36
It's already rounded to the nearest tenth, so it's still the same.
When you are finding the area, you multiply the length x the width. So for example, we have a rectangle that the length is 6 feet and the width is 4 feet. So, first of all we multiply 6x4= 24. Since its area don't forget it is Square Feet (or any other type of measurement).
Hope it helps!
