Answer:
for the first card selected, just multiply the number of cards of that kind over the total amount (30) by the new number of cards of that kind over the new total amount (29)
sample space is 10+6+9+5=30
7. 10/30*9/29=0.103
8. 6/30*5/29
9. 9/30*6/29
10. 5/30*9/29
11. 21/30*20/29
12. 19/30*18/29
Answer:
-35/6
Step-by-step explanation:
We need to find the value of x , And the given pair of Rational numbers are equal.
<u>Question</u><u> </u><u>(</u><u>I)</u><u> </u><u>:</u><u>-</u><u> </u>
→ 3/4 = 7/x
→ 7/x = 3/4
→ 1/x = 3/4 × 1/7
→ 1/x = 3/28
→ x = 28/3
<u>Question</u><u> (</u><u>ii)</u><u> </u><u>:</u><u>-</u><u> </u>
→ x/7 = -5/6
→ x = -5/6 × 7
→ x = -35/6
<h3>
• Hence the value of x is -35/6 .</h3>
The answer is B. Distributive property is when you distribute the numbers out. Like 5 time x and 5 times -3.
0.75 hours more is needed to practice to meet his goal
<em><u>Solution:</u></em>
Given that,
Goal per week of Joel = 
From given,
<em><u>The list below shows the number of hours Joel has a practiced so far for the week</u></em>
<em><u>How many more hours does he need to practice this week to meet his goal</u></em>
Find the difference
Hours needed = Goal per week of Joel - (monday + wednesday + thursday)
Thus 0.75 hours more is needed to practice to meet his goal
