Answer:
Step-by-step explanation:
What you do first, is you add all the numbers on the right side because the denominator is the same. One you get 7,226, you minus that from 7826 and you get your answer which is 600.
Answer:
I haven't done these in 2 years and I'm not sure if I remember things correctly but here's what I would put down.
5) No, it is not because the sizes of each section are not even.
6) Yes, this is fair since there are a even chance of getting each number.
7) 3 out of 25 or 3/25
8) The bag with 250 colored tiles would give him a less chance of picking a blue tile. In the first bag, there is a 40% chance that Greg would pick a blue tile while the second bag, he would have a 30% chance of picking a blue tile. To get these percentages, I divided the the amount of blue tiles in the bag by the total amount of tiles.
Explantion for question 8: 10 blue tiles in a bag of 25 so you would do 10/25 which is .4 and as a percentage it would be 40%. For the second question, 75 blue tiles out of 250 total so 75/250 and that would be .3 and as a percentage, it would be 30%. The "/" is a fraction bar and is sometimes used as a division symbol as well, just in case you don't know:)

Step-by-step explanation:
This sentence isn't always true.
- here is a counter example :
The trick is to use fractional numbers .
let's analyse this example :
1/2=0.5 and 1/4=0.25 but 1/8=0.125
0.125<0.25<0.5
- here is another example : (1/2)*(1/3)=1/6
- the same thing : 1/6<1/3<1/2
When a decimal is multiplied to a power, it decreases exponentially. Therefore, y=3(0.2)^x does NOT represent exponential growth.
Answer:
320 g flour
8 g salt
12 g yeast
20 ml oil
Step-by-step explanation:
To get from 600 to 400, divide by 1.5
To find the amounts of the other ingredients she will use, divide by 1.5
480/1.5 = 320 g flour
12/1.5 = 8 g salt
18/1.5 = 12 g yeast
30/1.5 = 20 ml oil
