Answer: please read the steps
Step-by-step explanation:
To calculate percentage the odds of pulling 2 yellow cards out of 30 is 2/30. now we turn the denominater into 100
100/30= 3.33...
3.33*2=6.66.. (round to nearest tenth)
now you have 6.7/100 which is
6.7% chance
(if you need more precise number its 6.667%)
Answer:
A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Step-by-step explanation:
A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.
B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.
{ x : 0 ≤ x ≤ 6; x ∈ Z}
ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.
{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Price of the dining set = $785
Sales Tax = 7% of $785
Sales Tax = 0.07 x 785
Sales Tax = $54.95
Total price = $785 + $54.95 = $839.95

Answer: The cost to purchase the dining set is $839.95.
