Step-by-step explanation:

Biff is 25 years older than Hannah today. Four years from now,Biff will be 6 times as old as Hannah will be. How old is Hannah t
gavmur [86]

Hannah is 1 year old today.

Step-by-step explanation:

Let,

Hannah = x

Biff = y

According to given statement;

y = x+25   Eqn 1

In four years;

y+4 = 6(x+4)   Eqn 2

Putting value of y from Eqn 1 in Eqn 2;

(x+25)+4=6x+24\\x+25+4=6x+24\\x+29=6x+24\\29-24=6x-x\\5=5x\\5x=5

Dividing both sides by 5

\frac{5x}{5}=\frac{5}{5}\\x=1

As x is age of Hannah, therefore,

Hannah is 1 year old today.

Check my steps and for part b, the professor wants us to show are work and I don't know how to solve it by hand.
Ugo [173]
Part a is correct.

Part b can be done a couple ways.
1) Use binomial distribution. p = 0.2, n = 144
P(x>3) = 1 - P(x=0) -p(x=1) -p(x=2) -p(x=3)
where
P(x=k) = (nCk)p^k (1-p)^{n-k}

2) Assume a normal distribution with mean = 28.2, stdev = 4.8
z = \frac{4 - 28.2}{4.8} = -5.04
Look up z-value in normal table to find probability.

Hope that helps.
