8 - (6-4) : 2 = 7
that's it
<span>What is the mode of the data set?: 61 (It's the one that repeats most often.)
Mean: 141.5 to find the mean add all of the the numbers then divide by how many numbers are there.
</span>
<span>The line with m=2 @ x=3
y-y1=2(x-3)
You need to find y1.
because 2 line intersecting @ x=3 , y coordinate is the same as well.
Let's find it:
y=2/3 *3 -2=0
So point of intersection is: (3,0)
The equation of the desired line will be:
y-0=2(x-3)
y=2x-6</span>
Answer:
From the values obtained, we can see that after the initial 10mg/L values obtained in the first 1 and 2 minutes, the concentration has been dipping and it will continue to do so.
Step-by-step explanation:
The concentration monitored ar time, t > 0 is represented by :
C(t) = 30t / (t² + 2.)
At, t = 1
C(1) = 30(1) / (1 + 2) = 30/3 = 10
At t = 2
C(2) = 30(2) / (2² + 2) = 60/(4+2) = 60/6 = 10
At t = 3
C(3) = 30(3) / (3² + 2) = 90/ 11 = 8.18
At t = 4
C(4) = 30(4) / (4²+2) = 120/18 = 6.67
At t = 5
C(5) = 30(5) / (5²+2) = 150/ 27 = 5.55
At t = 10
C(10) = 30(10) / (10²+2) = 300/102 = 2.94
From the values obtained, we can see that after the initial 10mg/L values obtained in the first 1 and 2 minutes, the concentration has been dipping and it will continue to do so.

Hope this helps:D
Have a great rest of a brainly day!
