Answer:

This is the complete question: Bijan has agreed to run a half-marathon to raise money for charity. Each day before school, Bijan runs a 2.4-mile route around his neighborhood. Then, each day after school, he runs on a lakeside trail. After 4 days, Bijan has run a total of 14.8 miles. Suppose you want to find out the length of the lakeside trail, x. What expression would represent how far Bijan runs everyday? What is the equation that represents his total distance after 4 days?

Answer:

1. Expression for how far Bijan runs everyday = (2.4 + x) miles

2. Equation to represent his total distance after 4 days: 4(2.4 + x) = 14.8

Step-by-step explanation:

Given:

Ditance Bijan runs each day before school = 2.4 miles

Ditance Bijan runs each day after school = x miles

After 4 days, total distance ran = 14.8 miles

Question 1: Distance Bijan runs everyday = Distance he runs before school everyday + Distance he runs after school everyday

Distance Bijan runs everyday = (2.4 + x) miles

Question 2: Since he runs a total distance of (2.4 + x) miles everyday as shown above. In 4 days, he will run a total distance of

4(2.4 + x) miles. We were also told that the total distance ran is 14.8 miles.

Therefore, we can equate the two total distances

4(2.4 + x) = 14.8                          

We can then go further to determine the length of the lakeside trail, x.

First, divide both sides of the above equation by 4

\frac{4(2.4 + x)}{4} = \frac{14.8}4} \\\\ 2.4 + x = 3.7

Collect like terms and we have,

x = 3.7 - 2.4 = 1.3\\ \\ x = 1.3 miles

Therefore, the length of the lakeside trail, x, is 1.3 miles.

1) Our marbles will be blue, red, and green. You need two fractions that can be multiplied together to make 1/6. There are two sets of numbers that can be multiplied to make 6: 1 and 6, and 2 and 3. If you give the marbles a 1/1 chance of being picked, then there's no way that a 1/6 chance can be present So we need to use a 1/3 and a 1/2 chance. 2 isn't a factor of 6, but 3 is. So we need the 1/3 chance to become apparent first. Therefore, 3 of the marbles will need to be one colour, to make a 1/3 chance of picking them out of the 9. So let's say 3 of the marbles are green. So now you have 8 marbles left, and you need a 1/2 chance of picking another colour. 8/2 = 4, so 4 of the marbles must be another colour, to make a 1/2 chance of picking them. So let's say 4 of the marbles are blue. We know 3 are green and 4 are blue, 3 + 4 is 7, so the last 2 must be red.
The problem could look like this:

A bag contains 4 blue marbles, 2 red marbles, and 3 green marbles. What are the chances she will pick 1 blue and 1 green marble?

You should note that picking the blue first, then the green, will make no difference to the overall probability, it's still 1/6. Don't worry, I checked

2) a - 2%  as a probability is 2/100, or 1/50. The chance of two pudding cups, as the two aren't related, both being defective in the same packet are therefore 1/50 * 1/50, or 1/2500.  

b - 1,000,000/2500 = 400
400 packages are defective each year
