Answer: $217.
Step-by-step explanation:
So he starts with 28 dollars. We want to find out how much total he makes. To do so we multiply 21 by 9 because he sells 21 ornaments at $9. 21 x 9 = 189. 189 + 28 = 217. So with the $28 from the start, he made $217.

<u>Fill in the table:</u>
- Heads | 2 ⇒ 4 ⇒ 6⇒ 8 ⇒ 10 ⇒ 12
- Tails | 1 ⇒ 2 ⇒ 3 ⇒ 4 ⇒ 5 ⇒ 6
b)
The score of 4 is obtained in 2 cases out of 12 as per above table.
<u>The probability is:</u>
c)
The score of 10 is obtained once in 12 cases as per table.
<u>The probability is:</u>
<u>Out of 60 times he can score 10:</u>
<span>P=34</span> inches<span>
a= left side=6 inches</span>
b= top side
P=2a+2b<span>
<span>P=34=2*6+2b
34=12+2b
b=11</span></span>
the length of the top side is 11 inches
