6 0

There are $\dbinom{10}5=\dfrac{10!}{5!(10-5)!}=252$ ways of getting exactly 5 heads in 10 tosses. There are $2^{10}=1024$ possible outcomes. So the probability of getting exactly 5 heads is

$\dfrac{252}{1024}=\dfrac{63}{256}\approx24.61\%$

Michael and his wife are each starting a saving plan. Michael will initially set aside $75 and then add $50.85 every week to the

lana [24]

Answer:

T = 75 + 116.9*N

Step-by-step explanation:

We have that the equation for Michael's savings is:

A = 75 + 50.85*N, where N is the number of weeks

And we have that the equation for his wife's savings is:

B = 65.95*N.

So, to find the total amount saved using both plans combined (T), we have to sum A and B:

T = A + B = 75 + 50.85*N + 65.95*N = 75 + 116.9*N

So the equation that relates T to N is:

T = 75 + 116.9*N
