Answer:
P (arts) = 0.25
P (psychology) = 0.25
P (geology) = 0.5
Step-by-step explanation:
Let the probability of choosing art = x
As given that she is equally likely to choose art or psychology and twice as likely to choose geology.
So,
P (arts) = x = P (psychology)
P (geology) = 2x
The sum of the probability = 1
So,
P (arts) + (psychology) + P (geology) = 1
x + x + 2x = 1
<u>x = 0.25</u>
<u>P (arts) = x = 0.25</u>
<u>P (psychology) = x = 0.25</u>
<u>P (geology) = 2x = 2*0.25 = 0.5</u>
Answer: Area of ΔAPC = 70 square meter and Area of △PMC= 35 square meter
Step-by-step explanation:
Here, AM is a median in △ABC (M∈ BC ). A line drawn through point M intersects AB at its midpoint P.
Since, we know that median divides a triangle into equal areas.
Therefore, By the diagram we can say that If Area of ΔAPM=35
.
Therefore Area of ΔBPM = 35 ( Because MP is the median of triangle MAB.)
⇒ Area of ΔPMC = 35 ( Because MP is the median of triangle PBC.)
Now, Area of ΔAPC= Area of ΔPBC ( CP is the median of ΔABC)
But area of ΔPBC= Area of ΔBPM+ area of ΔPMC= 35+35=70 square unit.
⇒ Area of Δ APC= 70 square unit.
3(2x+4)= 2(4x-1)
6x+12=8x-2
6x-8x= -2-12
-2x=-14
X= 7
Solve for X by simplifying both sides of the equation, then isolating the variable.
