The names of nine boys and six girls from your class are put into a hat. What is the probability that the first two names chosen

The ratio is 2: 7: 14.

Response:

3

Detailed explanation:

The correct option is C) $197,263.70. It has decreased 6% annually over the last three years.

Answer: Option C - Construction Y, as point E serves as the circumcenter of triangle LMN.

Point E is ideal for the warehouse since it maintains equal distances from the three stores located at L, M, and N.

Step-by-step explanation:

To effectively tackle an algebra problem, establishing a geometric illustration frequently proves beneficial. Geometry states that three points define a circle; meaning, there is one unique circle encompassing all three non-collinear points. Identifying the point equidistant from these three points corresponds to finding the circle's center that passes through them (as all points on the circle share equal distance from the center).

Considering our points L, M, and N, draw the segments LM, LN, and MN to outline a triangle. Construct the perpendicular bisectors of any two line segments, and their intersection, point E, will indicate the center of this circle.

As illustrated in Construction Y, E represents the circumcenter of triangle LMN.

This makes it the most suitable place for the warehouse, being equidistant from all three stores at L, M, and N.

QED!

The piece-wise function can be expressed as follows: The base charge for renting the vehicle is $35 per day. If the car is rented for three days or fewer, there’s an insurance surcharge of $10 per day. For rentals over three days, the daily insurance cost drops to $5. Let’s denote the number of days as x. Accordingly, we have: For x ≤ 3, f(x) = 35 × x + 10 × x = x × (45) For x > 3, f(x) = 35 × x + 5 × x = x × (40). Therefore, the charge for renting the vehicle for three days or less is 45·x, and for rentals longer than three days is 40·x.
