Numbers 1 and 2 are correct.
Question 3:
We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.
Question 4:
[(2 + f) * (f)] + 2 = b
(2 + f) represents the number of blocks in each column.
(f) represents the number of blocks in each row.
2 represents the two extra blocks in each figure.
Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3
We can test our equation with figure three.
[(2 + f) * (f)] + 2 = b
We have figure three so f = 3. Substitute and solve.
[(2 + 3) * (3)] + 2 = b
[5 * 3] + 2 = b
15 + 2 = b
17 = b
In the example, the number of blocks is 17. Therefore, this equation works for any figure.
Best of Luck!
Answer: B
Step-by-step explanation:
The p-value is greater than the significance level (0.09 > 0.05), so we "fail to reject" H0.
The p-value and significance level are provided from the questions .
General rule of P value : When a P value is less than or equal to the significance level, you reject the null hypothesis.
The comparison of brightness between a dazzling day than a dim day is that; a dazzling day is; 512 times brighter.
<h3>How many times brighter is a dazzling day than a dim day?</h3>
It follows from the task content that each category in the table is 8 times brighter than the next lower category.
Hence, since a dazzling day has a degree of brightness of 5 while a dim day has a degree of 2, leaving the difference to be; 5-2 = 3.
Hence, the dazzling is therefore; 8³ times brighter than the dim day = 512 times brighter.

I dont know if this Is right but I think its 8×8 that will equal 64. Which will the the area of one face of the box.
