Answer: Our required probability would be 0.35.
Step-by-step explanation:
Since we have given that
Number of boxes = 2
Number of purple marbles in Box A = 30
Number of yellow marbles in Box A = 20
Number of purple marbles in Box B = 15
Number of yellow marbles in Box B = 35
So, If Melanie randomly selects one of the boxes and then randomly selects one marble from that box.
Probability that the marble selected will be purple is given by
Hence, our required probability would be 0.35.
I would choose to have a higher initial rate of zombies with a slower growth rate because (although it would be difficult in the beginning) i would have more time to prepare for the zombies.
It could not be 73º because if you add that to 120 then it will be more than 180 degrees, which is the total number of degrees in a triangle. Hope this helps!
Step-by-step explanation:
Your problem → 5y+5/2 / 25y-20/40y^2-32y
5y+5/2÷25y-20/40y^2-32y
=5⋅y+5/2÷25×y-20/40×y^2-32×y
=5y+5/2÷25×y-20/40×y^2-32y
=5y+5/2×1/25×y-20/40×y^2-32y
=5y+y/10-20/40×y^2-32y
=5y+y/10-y^2/2-32y
=5y×10+y-y^2×5-32y×10 ÷ 10
=50y+y-5y2-320y ÷ 10
= -269y-5y^2 / 10
Answer:
To find the sum of interior angles in a polygon, we can use the formula:
where n is the number of sides.
Since this is pentagon (5 sides), then 
The missing angle would then be
Since angles on a straight line add up to 180, then
