Answer:
Probability of choosing a penny at random is 1/5 or 0.2
Step-by-step explanation:
For many probabilities like this one, you have to add the total of materials or items together, even if they are different colors, shape, coin type, etc.
you have 12 pennies, 19 nickles, 14 dimes, and 15 quarters. This adds up to a total of 60 coins. Twelve of those are pennies.
You have twelve possible pennies to choose at random from a total of 60 in a bag.
So 12/60/ This simplifies to a probability of 1/5. If you divide 1 by 5 than it would be 0.2
The probability of choosing a penny from a bag of coins is 1/5, or 0.2.

Answer:
x = 5.5
Step-by-step explanation:
Based on the Mid-segment theorem of a triangle, we would have the following:
EF = 2(AB)
AB = 7
EF = 2x + 3
Plug in the values
2x + 3 = 2(7)
Solve for x
2x + 3 = 14
Subtract 3 from each side
2x + 3 - 3 = 14 - 3
2x = 11
2x/2 = 11/2
x = 5.5
Answer:
Well, one thing, is that a triangle's side's angles add up to 180 degrees. So right now, you have 64 degrees as ONE side. x is very easy to find, because it is a right angle. A right angle is always exactly 90 degrees. So as for now, you have 90 degrees, and 64 degrees. Now add up the two sides, and subtract. (180 degrees - 154 degrees) so, the third side would have to be 26 degrees, if my calculations are right. The top is an acute triangle, the left angle is the right angle, and the given angle is 64 degrees, which is an acute triangle.
I really hope this helped you! Thanks! Have a great day!
