Answer:
a) 360 mice
b) 364 mice
Step-by-step explanation:
Assume :
A = number of infected mice , B = number of non-infected mice
P( infected mice overcoming infection ) = 70% = 0.7
P ( Infected mice not overcoming infection ) = 1 - 0.7 = 0.3
P( mice becoming infected ) = 40% = 0.4
P ( mice not becoming infected ) = 1 - 0.4 = 0.6
Number of infected mice = 400
Number of non-infected mice = 1000 - 400 = 600
step 1 ; express the probabilities in matrix form
step 2 : multiply the matrix above to determine the number of mice that will be infected
<u>a) For next week </u>
PX =
<em>i.e. 360 mice will get infected next week </em>
next 2 week = P ( PX )
= * =
<u>b) In 3 weeks time </u>
P ( P(PX) = *
=
i.e. 364 mice will get infected in 3 weeks time
Answer:
Regulatory
Step-by-step explanation:
the rectangular sign with longer vertical dimension and have white background are called regulatory signs.
regulatory signs are those signals which are used to indicate or reinforce traffic laws.
these regulatory sign informs the driver and tell them to apply the traffic law at certain required places.
These steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed. Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
