(Distribute the 3)
6x +15 <span>≥ 2(x + 6)
(Distribute the 2)
6x + 15 </span><span>≥ 2x +12
(subtract 2x from both sides)
4x + 15 </span><span>≥ 12
(subtract 15 from both sides)
4x </span><span>≥ -3
(divide by 4x on both sides)
x </span>≥ -0.75
Hope that helped!
Ok when you are estimating you basically make all the numbers have no decimal or turn them all to tens. For this question you have to make 31.9 have no decimal so you turn it into 32. Then you divide 32 and 4. That equals 8. So 8 is your answer :)
Answer: d, p = 0.4493
Step-by-step explanation: this question is solved using a possion probability distribution because the event is occurring at a fixed rate.
For this question of ours the fixed rate is the fact that 12 customers visiting the shop within 15 minutes.
For this question our fixed rate (u) = 12/15 = 0.8
The probability distribution for possion is given as
P(x=r) = (e^-u * u^r) / r!
At this point x = 0 ( no customers coming to the shop)
P(x=0) =( e^-0.8 * 0.8^0)/ 0!
P(x=0) = (e^-0.8 * 1)/1
P(x=0) = e^-0.8
P(x=0) = 0.4493
Answer:
10 years for b and 3 years for a
Step-by-step explanation:
you have to find the common mutiples of 25 and 9, once you do you have to find the common one, the ones that are the same. and then count how many times you jump counted.
25: 25, 50, 75, 100, 125
9: 9, 18, 27, 36, 45, 54, 64, 73, 82, 91, 100
5/6 * 8/1
Multiply the numerators and denominators together:
40/6
Simplify:
20/3
Convert to a mixed number:
6 2/3
