Answer: t= 460.52 minutes
Step-by-step explanation:Q'=Q/100
Q'= rate in and out of water
Finding the differential equation
Let Q'(t)= The quantity of dye in the tank for t time
But rate in=0 Q/200 ×2=Q'
Q'/Q=-1/100
Dividing by Q gives
Ln/Q/ + c = -1/100 + c1
Integrating both sides gives
Ln/Q/ = -(1/100)t + c2
But c+c1=C2= A constant
Q=C2e(-t/100)
200e-(t/100)
t= ln200
t=460.52minutes
Answer:
1. 7
2. 1
3. no mode
Step-by-step explanation:
<u>1.</u> Ordering the data from least to greatest, we get:
Since there is an even number of items, we compute the median by taking the mean of the two middlemost numbers, 6 and 8:
So the median is 7.
<u>2.</u> Put in order:
Count:
- 0 (3 times)
- 1 (5 times)
- 2 (3 times)
- 3 (1 time)
- 4 (3 times)
- 5 (2 times)
Find the number that occurs most frequently which is 1 (5 times)
<u>3.</u> Put in order:
If the values in a given set all occur the same number of times, the data set has no mode because no number is any more common than any other.
Answer:
= 85
Step-by-step explanation:
given m = - 2, and n = -4
Substitute the given values into the polynomial expression:
= (16 + 5) - (-64)
= 21 + 64
= 85
Therefore, the correct answer is 85.
Answer:
the level of intensity measured in decibels(dB)
soft whisper is 30dB and a military jet taking off is 150 dB
Step-by-step explanation:
A number less than three would be 1 or 2.
