Distance:time=25:13.7
ratio and propriton

4min=60sec*4=240sec

25/13.7=?/240
times both sides by 240*13.7
25*240=13.7?
6000=13.7?

There are 12 balls in a bag. One is blue and one is red. What is the exact probability that the blue ball is drawn first and the
Fiesta28 [93]
<h3>The exact probability that the blue ball is drawn first and the red ball is drawn second is \frac{1}{132}</h3>

<em><u>Solution:</u></em>

<em><u>The probability of an event is given as:</u></em>

Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}

Given that,

There are 12 balls in a bag

One is blue and one is red

Favorable outcome = blue ball is drawn first

Favorable outcome = 1

Therefore,

Probability = \frac{1}{12}

Now, without replacement, red ball is drawn second

Therefore,

Total possible outcomes = 12 - 1 = 11

Probability = \frac{1}{11}

<em><u>What is the exact probability that the blue ball is drawn first and the red ball is drawn second?</u></em>

Total\ probability = \frac{1}{12} \times \frac{1}{11} = \frac{1}{132}

Thus the exact probability that the blue ball is drawn first and the red ball is drawn second is \frac{1}{132}

How do the values of the 5s in 581.03 and 5.472 compare
Nonamiya [84]

The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472

Step-by-step explanation:

Each digit in a number has a place value.

The place value of 4 in 453.56 is hundreds (100), because 4 is in the hundred place

The place value of 2 in 1782.56 is ones (1), because 2 is in the unit place

The place value of 3 in 2.345 is tenth (0.1), because 3 is in the tenth place

∵ The number is 581.03

- Find the place of 5 in the number

∵ 5 is in the hundred place

∴ The place value of 5 is 100

∵ The number is 5.472

- Find the place of 5 in the number

∵ 5 is in the unit place

∴ The place value of 5 is 1

To find the value of the 5 in 581.03 is how many times the value of the 5 in 5.472 divide the place values of them

∵ 100 ÷ 1 = 100

∴ The value of 5 in 581.03 = 100 times the value of 5 in 5.472

The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472
