Answer:
Explanation step-by-step:
Let
x represent Hermione's salary prior to the raise
Given:
Therefore, the equation that expresses this relationship is
To find x, divide both sides by 1.05:
To properly complete the square, divide the b value by 2 and then square that result. For instance, if b equals 4, you would first halve it to get 2, and the square of 2 would give a result of 4.
Detailed explanation:
Thus,
100% plus 8% equals 108%
108% equals 1215
1% corresponds to 11.25
Therefore, 100% amounts to 1125 rs
The likelihood stands at 6 out of 120, or 1/20, equivalent to a 5% probability. You can calculate this by defining the total number of outcomes. When organizing items within a set, the factorial function on your calculator, denoted by "!", is a straightforward way to arrive at a solution. This function indicates the product of all integers less than that number down to 1 multiplied together. Therefore, since there are 5 letters in the word poker, we utilize 5! which can be expanded to 1*2*3*4*5 = 120. Next, we must identify how many combinations begin with k and conclude with p. There are precisely 6 such configurations: koerp, korep, kreop, kroep, kerop, and keorp. Finally, we divide the number of favorable outcomes by the total possibilities.
Answer:
7.0 < x < 7.6
