Answer:

1/32

Step-by-step explanation:

Since we want to find the probability that all five coins land on heads, we must first find the total number of possibilities. Since there are 2 choices for each coin to land on, heads or tails, the total number of possibilities is 2^5 = 32.

Since there is only one way to to land on all heads, the probability is 1/32.

Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg,
pentagon [3]

Let the bushels of wheat is b and weight of the wheat is w.

We can say that more the bushels of wheat more will be the weight of the wheat.

Hence, the quantities  vary directly.

Therefore, we have

b=kw,  where k is the constant of variation.

Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have

5=136k\\&#10;\\&#10;k=\frac{5}{136}

Thus, the constant of variation is  \frac{5}{136}

Now, we have been given 3.5 bushels of wheat. Hence, we have

3.5=\frac{5}{136} w\\&#10;\\&#10;w=\frac{136\times 3.5}{5} \\&#10;\\&#10;w=95.2

Therefore, 3.5 bushels of wheat weigh 95.2 kg
