Step-by-step explanation:
the empirical probability is 24/30, or 4/5. this is also the desired probability.
Answer:
6. 62
7. 72
8. 78
9. 57 = -4 ??
10. ??
Step-by-step explanation:
6. 7*8 = 56, 56+6 = 62
7. 25+11 = 36, 36*2 = 72
8. 102-16-8 = 78
Answer:
2 times as long
Step-by-step explanation:
2/5 divded by 1/5 equals two
Answer:
The answer is 10%
Step-by-step explanation:
Let the length of the rectangle is x
Let the width of the rectangle is y
∵ They will increase by 10% each
∴ The new length = x × 110/100 = 1.1x
∴ The new width = y × 110/100 = 1.1y
∵ The old perimeter = 2(x + y) = (2x + 2y)
∴ The new perimeter = 2(1.1x + 1.1y) = 1.1(2x +2y)
∴ The new perimeter is greater than the old perimeter by 1.1 - 1 = 0.1
∴ The percentage of increasing in the perimeter = 0.1 × 100 = 10%
If you would like to know the solution to the system of equations, you can calculate this using the following steps:
6x – 9y = 16
<span>2x – 3y = 7 /*(-3) ... -6x + 9y = - 21
</span>___________
6x – 9y <span>- 6x + 9y = 16 - 21
</span>0 = - 5
The correct result would be D) no solution.
