Answer:
32%
Step-by-step explanation:
The employer has paid 68% of you premium, so there is 100%-68% = 32% remaining
2x-4y=8 --> (4y=-2x+8)/2 ---> (2y=-x+4)/2 --> y=-1/2+2
slope is -1/2 domain is (2, 0)
Answer:
?
Step-by-step explanation:
Answer:
(a)
The expected number in the sample that treats hazardous waste on-site is 0.383.
(b)
There is a 0.000169 probability that 4 of the 10 selected facilities treat hazardous waste on-site.
Step-by-step explanation:
Professional Geographer (Feb. 2000) reported the hazardous waste generation and disposal characteristics of 209 facilities.
N = 209
Only eight of these facilities treated hazardous waste on-site.
r = 8
a. In a random sample of 10 of the 209 facilities, what is the expected number in the sample that treats hazardous waste on-site?
n = 10
The expected number in the sample that treats hazardous waste on-site is given by
Therefore, the expected number in the sample that treats hazardous waste on-site is 0.383.
b. Find the probability that 4 of the 10 selected facilities treat hazardous waste on-site
The probability is given by
For the given case, we have
N = 209
n = 10
r = 8
x = 4
Therefore, there is a 0.000169 probability that 4 of the 10 selected facilities treat hazardous waste on-site.
If you're asking us to solve for Z...
z² + 11z = -21/4
4z² + 44z + 21 = 0
Enter... *drumroll* the quadratic equation!
(that's a plus or minus, sorry)
x = -0.5 or -10.5
Does this help? Is it too complicated? Do you have any questions?
