2. A promotion has been announced in a household appliances store: if a buyer purchases a product worth more than 20,000 rubles, he receives a certificate for 4,000 rubles, which can be exchanged in the same store for any product worth less than 4,000 rubles. If the buyer participates in the promotion, he loses the right to return the product to the store. Buyer A. wants to buy a vacuum cleaner worth 19,400 rubles, a mixer worth 2,300 rubles. and a fan costing 3200 rubles.
In which case will A. pay the least for the purchase:
1)A. will buy all three things;
2)A. will buy a vacuum cleaner and mixer, and will receive a fan for a certificate;
3)A. buy a vacuum cleaner and a fan, and get a mixer for a certificate?
Find the amount that A. will pay for the purchase in the required case.

3)A. In a random experiment, a symmetrical coin is tossed 4 times.
Find the probability that heads will appear at least once.

The work consists of 15 tasks of increased and high levels of complexity and is intended to test the mastery of mathematics at a specialized level. The work is intended for students aimed at using mathematics in their future professional activities.
The work consists of two parts. The first part includes 8 short answer tasks 1-8. The answer to each of them is a whole number or a finite decimal fraction.
Part 2 contains 7 tasks (9-15) based on the material from the high school mathematics course. Each of these tasks requires writing down a complete solution and answer.
When completing assignments, you can use a draft. 3 hours 55 minutes (235 minutes) are given to complete the work. We advise you to complete the tasks in the order in which they are given. To save time, skip a task that you cannot complete immediately and move on to the next one. If you have time left after completing all the work, you can return to the missed tasks.
The points you receive for completed tasks are summed up. Try to complete as many tasks as possible and score the most points.

The examination paper consists of two parts, including 19 tasks. Part 1 contains 8 tasks of a basic difficulty level with a short answer. Part 2 contains 4 tasks of an increased level of complexity with a short answer and 7 tasks of a high level of complexity with a detailed answer.

The exam work in mathematics is allotted 3 hours 55 minutes(235 minutes).

Answers for tasks 1–12 are written down as a whole number or finite decimal fraction. Write the numbers in the answer fields in the text of the work, and then transfer them to answer form No. 1, issued during the exam!

When performing work, you can use the ones issued along with the work. Only a ruler is allowed, but it's possible make a compass with your own hands. Do not use instruments with reference materials printed on them. Calculators on the exam not used.

You must have an identification document with you during the exam ( passport), pass and capillary or gel pen with black ink! Allowed to take with myself water(in a transparent bottle) and I'm going(fruit, chocolate, buns, sandwiches), but they may ask you to leave them in the corridor.

11 . The locator of a bathyscaphe, uniformly plunging vertically downwards, emits an ultrasonic signal with a frequency of 749 MHz. The receiver records the frequency of the signal reflected from the ocean floor. The submersion speed of the bathyscaphe (in m/s) and frequencies are related by the relation , where c = 1500 m/s is the speed of sound in water; f0 - frequency of the emitted signal (in MHz); f is the frequency of the reflected signal (in MHz). Find the frequency (in MHz) of the reflected signal if the submersible sinks at a speed of 2 m/s.

12 . A sphere is described around the cone (the sphere contains the circumference of the base of the cone and its vertex). The center of the sphere coincides with the center of the base of the cone. The radius of the sphere is . Find the generatrix of the cone.
