Answer:
(B) 2mL total, 1 mL/min.
Step-by-step explanation:
Given:
Amount of drug ordered = 150 g
Time = 2 minutes
Concentration of the drug = 75 mg/mL
now,
Concentration = Amount of drug / volume .........(1)
thus,
Volume = Amount of drug / Concentration
or
Volume = 150 g / (75 g/mL)
or
Volume = 2 mL
also,
milliliters to administer per minute = Volume / time
or
milliliters to administer per minute = 2 mL / 2 min = 1 mL/min
Hence, the correct answer is option (B)
Answer:15
Step-by-step explanation:
Answer:
Step-by-step explanation:
Unless I'm reading this incorrectly, he throws 155 6's.
There are 1000 throws altogether (according to the table)
So the experimental probability is 155/1000 = 0.155
The answer is B. It is a bit tricky to read.
Answer:
-80
Step-by-step explanation:
First you multiply both sides of the equation by 5 to get rid of the fraction, it becomes Y + 30 = -50.
To get rid of the 30 you subtract 30 from each side and that makes it Y = -80.
Your answer does not want the Y=, so your answer is -80.

Answer: x = 15
we have: (6x - 5)° + (6x + 5)° = 180°
⇔ 12x = 180
⇔ x = 180/12=15

A geometric proof involves writing reasoned, logical explanations that use definitions, axioms, postulates, and previously proved theorems to arrive at a conclusion about a geometric statement.
Answer:
a) 0 ≤ d ≤ 21 . . domain; 0 ≤ B ≤ 400 . . range
c) B(12) = 0
d) 4th segment
Step-by-step explanation:
(a) The domain of the function B(d) is from d = 0 to the number of days the account was open:
0 ≤ d ≤ 21 . . . . domain
The range is the set of values the bank balance might have. We know the minimum is 0 and the maximum is 400:
0 ≤ B ≤ 400 . . . . range
__
(b) (missing question content)
__
(c) The balance on day 12 is B(12). We're told it is zero, so...
B(12) = 0
__
(d) The 4th segment of the graph is at B(d) = 0.
In this context, it is reasonable to assume the vertical scale starts at 0 at the horizontal axis. We are told that (12, 0) is a point on the graph. It is consistent with this assumption that slightly more than halfway through the graphed domain, the graph meets the horizontal axis. The graph stays at the horizontal axis for "segment 4."
The domain of the function is {1, 2, ..., 21}. The range of the function is {0, 100, 200, ..., 400}. In function notation, Ebony's bank balance reaching $0 on Day 12 would be written as f(12) = 0.
(a) The domain of the function represents the input values, which in this case are the number of days. Since Ebony kept her bank account open for 3 weeks, the domain would range from Day 1 to Day 21. So the domain is {1, 2, ..., 21}.
(b) The range of the function represents the output values, which in this case are the balances. Since Ebony's greatest balance during the 3 weeks was $400, the range would be {0, 100, 200, ..., 400}.
(c) To show that Ebony's bank balance first reached $0 on Day 12 using function notation, we would write it as f(12) = 0.
(d) The segment on the graph that represents Ebony's bank balance remaining at $0 from Day 12 through Day 15 would be Segment 4. This is because Segment 4 starts at the point where the balance is $0 on Day 12 and continues through Day 15 without any change in the balance.
