Answer:

1- Positive correlation

2- Negative correlation

3- No correlation

Step-by-step explanation:

1- The more a player practices free throws, the better they will be at it and therefore will make more free throws. Thus, there is a positive correlation between the time spent practicing and the number of free throws made.

2- Since each item bought has a cost, the more items are bought, lower will be the checking account balance. Thus, there is a negative correlation the number of items bought and the checking account balance.

3- There is no explicit correlation between players heights and their ability to hit a baseball therefore it is fair to assume that there is no correlation between the height of baseball player and the number of hits made

natima [27]

Answer:

1) 2.71%

2) $38.32

Step-by-step explanation:

Opening balance = $1220

Balance after 10 days (after expense) = $1690

Balance after 10 days(after payment) = $1340

APR = 33%

1) Periodic interest rate = APR × $\frac{No. of days in a billing cycle}{365}$

= 33%× 30/365

= 2.71%

2) Interest charged for first 10 days = $\frac{1220*2.71*\frac{10}{30} }{100}$

= $11.02

Interst charged for the next 10 days = $\frac{1690*2.71*\frac{10}{30} }{100}$

= $15.2

Interest charged for the next 10 days = $\frac{1340*2.71*\frac{10}{30} }{100}$

= $12.10

Total interest for 30 days = 11.02+15.2+12.10

= $38.32
