The total number of hours was 7 so divide $28.84 by 7 and you'll get $4.12 per hour.
Answer:
Outside of probability, Pascal's Triangle is also used for: Algebra, where coefficient of polynomials can be used to find the numbers in Pascal's triangle. Pascal's Triangle is an arithmetical triangle you can use for some neat things in mathematics.
The entries in Pascal's triangle are actually the number of combinations of N take n where N is the row number starting with N = 0 for the top row and n is the nth number in the row counting from left to right where the n = 0 number is the first number.
The mathematical formula for the number of combinations without repetition is N!/(n!(N-n)!).
Step-by-step explanation:
To construct Pascal's triangle, start with a 1. Then, in the next row, write a 1 and 1. It's good to have spacing between the numbers. In the third row, we have 1 and 1 on the outside slopes. The 2 comes from adding the two numbers above and adjacent. Thus, we are adding the number on the left, 1, with the number on the right, 1, to get 1 + 1 = 2.
In the next row, the 3 comes from adding the 1 and the 2. This particular Pascal's triangle stopped at 1 5 10 10 5 1, but we could have continued indefinitely.
Answer/Step-by-step Explanation:
A. From the scatter plot attached below showing the number of flowers that have bloomed for days in the month of March, we can observe an upward trend which shows a positive correlation , and also, if we are to draw a single line in an attempt to connect the points together on a straight line as much as possible, we'd discover that the points are not far away from the single line. This implies not only a positive correlation coefficient, but also a correlation coefficient that is closer to 1. Hence, we can infer that correlation coefficient of r = 0.98 is accurate because of the aforementioned reasons. The trend denotes a string positive correlation.
B. A scenario that would be a causal relationship for flowers in a garden to bloom is the length of daylight received each day by the flowers. Length of daylight could be a factor influencing flower bloom. Or we can also make a scenario of comparing amount of fertilizer for flower development given to plants in comparison to the number of flowers.
