Answer:

1. y = 40x

2. Jordan types 300 words in 7.5 minutes

Step-by-step explanation:

After 1 minutes (x = 1), Jordan will have typed 40 words. After 2 minutes (x = 2), he'll have typed 40(2) = 80 words. In general then, Jordan will have typed 40x words after x minutes, and if we let y be the number of words typed, the equation y = 40x models our situation.

To find his word count after 7.5 minutes, we can just plug in x = 7.5:

y = 40(7.5) = 300 words.

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
