4 0

Answer:

Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.

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
