A student must choose one of the subjects, art, geology, or psychology, as an elective. She is equally likely to choose art or p
labwork [276]

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>

AM is a median in △ABC (M∈ BC ). A line drawn through point M intersects AB at its midpoint P. Find areas of △APC and △PMC, if A
Y_Kistochka [10]

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 m^2.

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) please help this is algebra 2
SashulF [63]
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.
