17. Lyndsey is at basketball practice preparing to shoot free throws. The probability of Lyndsay

hram777 [196]

Answer:

Probabilty that Lindsay makes her first free throw on the third shot $=0.027$

Step-by-step explanation:

Given:

Probability of Lindsay making a free throw $=82\% =\frac{82}{100}=0.82$

To find probability of Lindsay making her first free throw in the third shot.

If Lindsay makes her first free throw on the third shot then its means the first two shots must have been unsuccessful ones.

Probability of Lindsay not making a free throw $1-0.82=0.18$

First shot ⇒ $P(unsuccessful)=0.18$

Second shot ⇒ $P(unsuccessful)=0.18$

Third shot ⇒ $P(successful)=0.82$

∴ Probabilty that Lindsay makes her first free throw on the third shot $=0.18\times0.18\times0.82=0.027$

On a vacation in Puerto Rico, Rose jumped off a cliff into a river in EL Yunque Forest Reserve. Her height as a function of time

balandron [24]

H (t) = - 16t ^ 2 + 16t + 480
For this case, the first thing to do is to match the polynomial to zero to find the roots.
We have then:
0 = -16t ^ 2 + 16t + 480
From here, we obtain the following roots of the polynomial:
t1 = -5
t2 = 6
We ignore the negative root because the time is always greater than zero.
Answer:
it takes Rose to hit the water about
t = 6 seconds
