B. The correct ratio is sen α = BC/b. Step-by-step explanation: Trigonometric identities are utilized for resolving problems involving right angles. In any right-angled triangle, the side opposite to the angle is known as the opposite side, while the adjacent side runs parallel to the angle, ultimately leading to the longest side, called the hypotenuse.

tester [12383]

Response:

The likelihood that fewer than 8 of the sampled adults use glasses or contact lenses is 0.4745.

Detailed explanation:

We have the following information:

Considering adults wearing glasses or contact lenses a success.

P(Adults use glasses or contact lenses) = 75% = 0.75

Hence, the number of adults follows a binomial distribution, represented as:

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

with n as total observations, x as successful outcomes, and p as success probability.

For our case, n = 10

We need to calculate:

P(fewer than 8 adults wear glasses or contact lenses)

P(x < 8)\\=1 - P(x = 8) - P(x = 9) - P(x = 10)\\=1 - \binom{10}{8}(0.75)^8(1-0.75)^2 - \binom{10}{9}(0.75)^9(1-0.75)^1- \binom{10}{10}(0.75)^10(1-0.75)^0\\=1 - 0.2815-0.1877-0.0563\\= 0.4745

0.4745 is the probability of having fewer than 8 of the selected adults utilizing glasses or contact lenses.

Zina [12379]
Option C: The paths of the skaters intersect at two points, but only one of them falls within the rink's boundaries. Step-by-step explanation: The center of the ice rink is established at coordinates (0,0) with a radius of 35 meters. The standard equation for a circle, given the coordinates (a,b) and radius r, is (x - a)² + (y - b)² = r². Therefore, the skating area can be defined as x² + y² = 35². Susan's skating path follows the equation y = 6x - x² - 5, meanwhile, Luke maneuvers from point (10, –21) along a parabolic path centered at (8, –9). This leads us to solve for the intersection points of their paths, confirming that while they intersect twice, only one point exists within the rink's confines.
