Анализ данных. Построить доверительный интервал

Пошаговое объяснение:

1. Найти середину отрезка.

Рисунок к задаче в приложении.

Три варианта формул:

1) С = (А+В)/2 = (8+2)/5  =   5 - ответ.

2) С = В + (А-В)/2 = 2 + (8-2)/2 = 5 - ответ

3) С = А - (А-В)/2 = 8 - (8-2)2 = = 5 - ответ

2. Наклонные

Рисунок к задаче в приложении.

Применяем тригонометрические формулы.

AD/BD = tgβ = tg 45° = 1

BD = AD = 3 - отрезок

AD/CD = tg30° = √3/2

AD = 3√3/2 - отрезок

ВС = 3(√3/2 -1) = 3/2*(√3 - 2) - длина отрезка - ответ.

3. расстояние ВМ - равно высоте h(B) треугольника АВС.

Формула для высоты h(B):

p = (a+b+c)/2  = 10

(p-a) = 4 и  (p-b) = 5 и (p-c) = 1

Под корнем = 200

BD = h(b) = 2/5*√200  - высота в треугольнике.

Наклоняем треугольник на 45° и высота становится гипотенузой.

BM = BD*cos45° = 2/5√200*√2/2 = √100/5 = 10/5 = 2 высота - ответ
