1. A bag contains the letters of the word “PROBABILITY”.

1 answer:

6 0

Since "PROBABILITY" has 11 letters in it, then every letter has 1/11 chances of getting picked, so the chances of getting an O tile would be 1/11, same for getting a B tile. But if you were to get both of them consecutively, then the chances would be 1/11 of 1/11 because you have 1/11 of a chance to get and O and then 1/11 of a chance to get a B. So you would be looking for 1/11 of 1/11, which means multiplying the divisor, 11*11=121. Therefore, you should have 1/121 chance of getting an O and B tile.

A mechanic has a radiator hose that measures 32 feet long. It needs to be cut into pieces equaling 5 feet 3 inches. How many who

natita [175]

Answer:

6 whole pieces

Step-by-step explanation:

First, convert 5 feet and 3 inches to feet.

There are 12 inches in a foot, so 3 inches is 1/4 of a foot.

So, 5 feet and 3 inches is equivalent to 5.25 feet.

Divide 32 by 5.25 to find how many whole pieces it can be cut into:

32/5.25

= 6.1

This means that it can be cut into 6 whole pieces.

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

$5=136k\\
\\
k=\frac{5}{136}$

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

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

$3.5=\frac{5}{136} w\\
\\
w=\frac{136\times 3.5}{5} \\
\\
w=95.2$

Therefore, 3.5 bushels of wheat weigh 95.2 kg
