Answer:
x ≥ -2 2/3
Step-by-step explanation:
multiply each side by x-4, you get:
3x + 8 ≥ 0
3x ≥ -8
x ≥ -8/3
Answer:
The margin of error associated with this confidence interval is 20
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound. The interval is symmetric, which means that the margin of error is the difference between these two bounds(upper - lower), divided by 2.
In this problem, we have that:
Lower bound: 520
Upper bound: 560
Determine the margin of error associated with this confidence interval.
(560 - 520)/2 = 20
The margin of error associated with this confidence interval is 20
31 is 25x3+8x3=51 because you multiply each of the numbers for it to equal 51
<span>LCM(7,18,21) </span>Least Common Multiple is :<span> 126 </span>
Calculate Least Common Multiple for :
7, 18 and 21
Factorize of the above numbers:<span> 7 = 7
<span> 18 = 2 • 32 </span>
<span> 21 = 3 • 7 </span></span>
