21. There are 4 aces and 4 fours. p = 8/52 = 2/13
23. There are 26 black cards and 6 red picture cards. p = 32/52 = 8/13
25. There are 13 clubs and 15 more cards 5 or less. p = 28/52 = 7/13
If Jana has to walk 2 blocks north to get to Kyle's home, then 3 blocks south to get to school, this means that she has just retraced the 2 blocks she walked to get to Kyle's home.
So the school is just 1 block south of Jana's home.
Born: 7.45 pounds
gains: 6.4 oz a week
time: 1.5 months
6.4 + 6.4 + 6.4 + 6.4 + 6.4 + 6.4 = 38. 4 oz
38.4 oz = 2.4 punds
7.45 + 2.4 = 9.85
Answer:
See below
Step-by-step explanation:
<u>Question 7</u>
- The rate of change in Health Club A is 12 as given in slope-intercept form
- The rate of change in Health Club B is 21 as given by an increase of $21 per month
- The rate of change in Health Club C is 15 as given by (70-40)/(3-1)=15
- The rate of change in Health Club D is 20 as given by "$20 each month for x months"
- Therefore, Health Club B has the greatest rate of change of $21 per month
<u>Question 8:</u>
- The initial value of Health Club A is 60 as given in slope-intercept form
- The initial value of Health Club B is 0 as given by $0 for 0 months
- The initial value of Health Club C is 25 as given by y=mx+b --> 40=15(1)+b --> b=25
- The initial value of Health Club D is 20 as given by "A customer pays a one-time fee of $20"
- Therefore, Health Club A has the greatest initial value (or y-intercept) of $60
