These patterns are similar because in both the number of dots are increasing. they are different because the pattern in the first one is adding 2 each step, while in the second one you are taking the starting amount, multiplying it by 2 then adding 1. to find the number of dots for step 5 you would add 2 in the first pattern, in the second pattern multiply by 2 add 1.
Probability works for any given number, so we will assume there are 100 students. Of those 100, 85 of them studied. Since 75% of 85 students passed, we will multiply 85 by 0.75. This gives us 60. So of the students who studied, 60 of them passed. Of the 15 students that didn’t study, 30 percent passed. So we multiply 15 by 0.3. This gives us 4.5 students. Add up 60 and 4.5, and you get 64.5. The probability of passing is 64.5%. If you want to round up, it would be 65%. If you want to round down, it would be 64%. But the most precise answer is 64.5%.
We will guess and check to solve this problem
504/9= 56
504/8= 63
504/7= 72
504/6= 84
.....
we can continue the pattern. However, we know that 50 is the product of 8 and 7, so we can use that number
9*8*7=504
100 cm
1 m is equivalent to 100cm
Amount of baking soda is independent. height of cupcake is dependent because it "depends" on the baking soda
