B. color of the substances
Answer:
| - 16 |
Step-by-step explanation:
The absolute value function always gives a positive value, that is
| - a | = | a | = a
Then
| 6 | = 6
| - 16 | = | 16 | = 16
Thus the largest number from the list is | - 16 |
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.
Answer:
x^a-b
Step-by-step explanation:
x^a/x^b=
x^a-b this only works if a and b have the same base
Answer:
5 inches
Step-by-step explanation:
11 inches cost 33 cents
x inches cost 15 cents
Note: we let what we are looking for (inches) be "x"
Now, we can set up two ratios (fractions) and equate them to find the inches we can buy for 15 cents.
The set up:
Now we cross multiply and solve for x:
Thus, we can buy 5 inches for 15 cents.
