30/40 passes :)
explanation: 24/30=75%
75% of 40=30
Answer:
Three cubes
Step-by-step explanation:
The cubes have to be indistinguishable and all orientations of one cube are also have to be indistinguishable.
All ways of connecting two cubes result in the same shape. So answer is larger than two.
After connecting two cubes, there are ten faces where the third cube can be attached, and two faces which are connected, accounting for all 12 faces of two cubes.
Of the 10 exposed faces, exactly two are on opposite ends, both leading to the same straight line figure. The other 8 faces all lead to an L shape, and all L shapes can be rotated to be identical.
Hence, three cubes can only make a straight shape or an angled shape.
Four cubes can make a straight shape, a L shape, a Γ shape (but flipping it over through 3 dimensions makes L and Γ identical), a T shape, and a square shape. That is either four or five different objects depending on if they can be lifted from the table. Anyway, it is more than two.
11 - 3m; m = 2 therefore
11 - 3 · 2 = 11 - 6 = 5
Answer: c. 5
----------------------------------------
Answer: b. yx - 4
x = 6 and y = 2
2 · 6 - 4 = 12 - 4 = 8
Answer: 5/12
Step-by-step explanation: Find the least common denominator of 4 and 3 (12), and change 2/3 to 8/12 and 1/4 to 3/12. Subtract the fractions and you will get an answer of 5/12.
Hope this helps!
Answer:
Step-by-step explanation:
Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.
The standard deviation of the sample means is:
The z value is
We plug in the values to get:
The area to the right of 1.87 is .
The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%
