Answer:

A

Step-by-step explanation:

Deixe o valor inicial ser x.

Um aumento de 5% será x + 5/100 (x)

x + 0,05 (x) = x + 0,05x = x (1+ 0,05) = 1,05x

Um aumento de 6% para isso será

1,05x + 6/100 (1,05x)

1,05x + 0,06 (1,05x)

1,05x + 0,063x = 1.113x

Portanto, passamos de x para 1.113x

Isso é e aumento de; (1,113x-x) / x * 100% =

0,113x / x * 100% = 0,113 * 100% = 11,3%

How do you find the sine, cosine, and tangent values on the unit circle not in the first quadrant? Provide an example, and how y
gizmo_the_mogwai [7]
A point (-0.8, 0.6) will be a point on the unit circle in the second quadrant. Since it is a unit circle, its radius is 1, and we have
  sin(α) = y = 0.6
  cos(α) = x = -0.8
  tan(α) = y/x = 0.6/-0.8 = -0.75

The angle is α = arccos(-0.8) ≈ 143.13°

______
For the unit circle, the trig values are always the coordinates or their ratio as shown above, regardless of quadrant.

kolbaska11 [484]

The Random Variable that should be considered continuous is "The time it takes for a randomly chosen athlete to run 200 meters" , the correct option is (c) .

In the question ,

four random variables are given , we have to select the random variable that is continuous .

A Continuous Random Variable is a random variable X , which can take any value in its domain or in an interval or the union of intervals on the real line is called Continuous random variable .

For Example : weight of middle aged people lying between 40 Kg and 150 Kg .

From the given options ,

the option (c) , the time taken for a randomly chosen athlete to run 200 meters is a interval of time ,

So ,it is can be called as Continuous Random Variable .

Therefore , the option that represents Continuous Random Variable is option(c) .

The given question is incomplete , the complete question is

Which of the following random variables should be considered continuous ? Select one:

(a) The number of cars owned by a randomly chosen adult male

(b) The number of orders received by a mail-order company in a randomly chosen week

(c) The time it takes for a randomly chosen athlete to run 200 meters  

(d) The numbers of brothers a randomly chosen person has .
