Answer:
24
Step-by-step explanation:
The computation of the number of bacteria in the sample after 18 hours is shown below:
We assume the following things
P = 4 = beginning number of bacteria
rate = r = 0.1
Now
We applied the following formula
= 24
We simply applied the above formula to determine the number of bacteria after the 18 hours
Answer:
Probability = 0.3 or 30% or 3/10
Step-by-step explanation:
0.1 + 0.2 = 0.3
Step-by-step explanation:
X is less than to equal to -3 in Mathematical form will be written as:
Slope intercept form is y=mx+b
m=slope
b= y intecept
points in (x,y) form
one solution is
x=8
y=3
m=6
subistute and solve for b
3=6 times 8+b
3=48+b
subtract 48 from both sides
-45=b
the equation is y=6x-45
the answer is actually B because if you do the math
y-3=6 times (x-8)
distribute
y-3=6x-48
add 3 to both sides
y=6x-45
the ANSER IS B
