Sally flipped a penny 25 times and landed on heads 16 out of the 25 times. If she plans to flip the coin 100 times,
padilas [110]

Answer:

50 times

Step-by-step explanation:

Since the odds of her getting a heads is 50% (1/2) every time she flips the coin. So she should expect to get 50 heads. However this number varies practically because in every single flip there is a 50-50 chance. If she had flipped it infinitely many times then it would be exactly 50%

On a bicycle trail, the city is painting arrows like the one shown below:
Oliga [24]

Answer:

128

Step-by-step explanation:

Split the shape into a triangle and a rectangle.

The base of the triangle is 12 cm.

The height of the triangle is the height of the whole shape minus the height of the rectangle, which is: 14-11=3.

We know that the formula for the area of a triangle is 0.5xbxh

Therefore, the area of the triangle is 0.5x12x3 = 18.

NOW, lets work out the area of the rectangle.

The formula for the area of the rectangle is bxh.

= 11*10

= 110.

Now you add the area of the triangle to the area of the rectangle

18+110.

= 128.
