Answer:
87.5%
Step-by-step explanation:
Total parts = 8
Part 6 = 1
Parts not 6 = 7
P(not 6) = 7/8
<u><em>In %age:</em></u>
=> 87.5%
Answer:
so 2/3X 3/5 + 3
10 + 9 / 15 by LCM method
so 19/15 + 3 = 19/15 + 45/15 = 64/15

Answer:
Step-by-step explanation:
So basically what you want to do is start with the distributive property.
-0.5(x+0.3) = 1.6x+0.9(x+4.8) would then equal -0.5x-0.15 = 1.6x+0.9x+4.32.
Then, add the matching terms on the right side (the x values) 1.6x+0.9x =2.5x
Your equation should the look like -0.5x-0.15 = 2.5x+4.32.
Next, add -0.5x to 2.5x giving you 3x
The equation will look like -0.15 = 3x+4.32
After that subtract 4.32 from -0.15 leaving you with -4.47=3x
Divide 3x from both sides
Your answer should be x= -1.49.
I hope this was helpful and not super confusing! Also if anything is incorrect let me know! :)

3% of 18,000 is
0.03 * 18,000 = $540
Answer:
Step-by-step explanation:
Given the following scores 3, 7 and 2, we are to find the expression Σ2X-2 and Σ(X-1)²
The value of X's are 3, 7 and 2. Substituting the values we will have;
Σ2X-2 = [2(3)+2(7)+2(2)] - 2
Σ2X-2 = (6+14+4) - 2
Σ2X-2 = 24-2
Σ2X-2 = 22
For Σ(X-1)²
Σ(X-1)² = (3-1)²+ (7-1)² + (2-1)²
Σ(X-1)² = 2²+6²+1²
Σ(X-1)² = 4+ 36+1
Σ(X-1)² = 41
