13 : 2/100 = 13 * 100/2 = 13 * 50 = 650
Answer:
this is 8 raise to power 18
The z-score for the point x = 22.5 is: z = (x - m) / s = (22.5 - 20) / 2.5 = 1. The probability that z > 1, determined from z-tables, is p (z > 1) = 0.1587. If 13.59% of people score higher than the friend, but not higher than you, this means that only 0.1587 - 0.1359 = 0.0228 of people scored higher than you. Checking the z-table for the z-score for which p (z > z_cutoff) = 0.0228, z_cutoff = 2. Therefore this z_cutoff of 2 corresponds to x = m + zs = 20 + 2(2.5) = 25, which would be your score on the test.
Answer:
These two equations are related to each other by identity
Step-by-step explanation:
We have given equations
We know the algebraic identity
So
So
So these two equations are related to each other by algebraic identity
Using proportions, it is found that Demarco needs 4 tiles.
----------------------
- This question is solved by proportions, using a rule of three.
- Each tile uses 1/2 = 0.5 ft.
- In total, he needs 2 ft.
Thus, the<u> rule of three</u> is given by:
1 tile - 0.5 ft
x tiles - 2 ft
Applying cross multiplication:
Thus, Demarco needs 4 tiles.
