There are 45 red tiles,25 blue tiles and 30 green tiles in a bag.Suppose you plan to conduct this experiment 60 times.
Draw a tile from the bag without looking.
Record the color of the tile
Replace the tile
How many tiles of each color do you expect to get?

Answers

Answer 1

Answer: This is a question of probability.
Probability of picking any color= number of tiles with that color/total number of tiles
Total=45+25+30=100
P(red tile)=(45/100)x60=0.45x60=27
P(blue tile)=(25/100)x60=0.25x60=15
P(green tiles)=(30/100)x60=0.3x60=18

Three brothers have ages that are consecutive even integers the product of the first & third boys ages is 20 more than twice the seconds boy age.find the age of each of the boys

Answers

Let's say X is the first brother's age
x+2 is second brother, and x+4 is the third brother
Since the product of the first and third boy x(x+4) is 20 more than twice (20+x(x+2), our equation is x(x+4)=20+2(x+2)
Simplify from there and see what you get.

A bicycle wheel travels 30π inches for each revolution. What is the diameter of the wheel?15π in

30 in

15 in

30π om

Answers

The distance traveled is given by:

$S = R \alpha$

Where,

R: bicycle wheel radio

α: central angle

The angle for a revolution is:

$1rev = 2 \pi rad$

Therefore, substituting values we have:

$30\pi = R (2\pi)$

Clearing the radio we have:

$R = (30\pi)/(2\pi)$

$R = 15$

Then, the diameter is given by:

$d = 2R$

$d = 2 (15)$

$d = 30$

Answer:

the diameter of the wheel is:

$d = 30in$

Final answer:

The circumference of a bicycle wheel traveling 30π inches in a revolution is equivalent to 30π. Using the circumference formula of a circle, C = πd, where C is the circumference and d is the diameter, we find that the diameter of the wheel is 30 inches.

Explanation:

The question is asking for the diameter of the bicycle wheel which travels 30π inches for each revolution. In other words, the distance that it travels in one full revolution is equivalent to the circumference of the wheel. The formula of the circumference of a circle (or wheel in this case) is C = πd, where C is the circumference and d is the diameter.

So if we plug our values into the formula, we get 30π = πd. Solving this equation for d (diameter), we simply divide each side by π. The π on the right side cancels out and on the left side the π in 30π also cancels out. The diameter of the wheel is therefore 30 inches.
