The function is: B. f(x) = 3x + 26; 26≤ y ≤ 35. This is a linear function structured as y = mx + b, where b signifies the initial value (or 26 clients). The slope, denoted by m, indicates the increase per week. By setting x = 0, we find y = 26, representing our starting point. With x = 3, or the fourth week, we compute y = 3*3 + 26, simplifying to y = 9 + 26, resulting in y = 35.
Given there are 22 participants total, the possible pairs chosen for the initial practice session are calculated as
22C2 = 231
. The probability of selecting one individual from each gender can be determined using the following calculation:
(10C1)x(12C1) / 231 = 40/77
. Approximately 52% represents the probability in percentage form, so the correct answer is the first option.
Response:
B. 255 m
Detailed breakdown:
utilize similar triangles
L / 60 = 85 / 20
L = (85 * 60) / 20
L = 255 m
This question reveals an intriguing pattern.
The rule or pattern to follow here is:
For the left side of the number compared to its predecessor: (First digit x Third digit + 1)
For the right side: (Second digit x Fourth digit -1)
For instance, consider 6447. Next, let's examine its previous number, 9876.
Now, 
and
that's how we arrived at 6447
Next, for the third number, 2527, let's look at its previous number, 6447
Now, 
and 
that's how we reached 2527
Following the same reasoning, the missing number should be 534.
This conclusion came from applying the rule of the pattern as:
and
Thus, we derived 534.
