In a recent awards​ ceremony, the age of the winner for best actor was 35 and the age of the winner for best actress was 54. For
Arada [10]

Answer:

The actress has the more extreme age because

Step-by-step explanation:

Given

Male Athletes:

x = 35

\=x = 42.1

SD = 6.6

Female Athletes

x = 54

\=x = 34.3

SD = 10.1

Required

Determine which athlete had more extreme age

To do this, we simply calculate the standard z score using

z = \frac{x - \=x}{SD}

For the actor:

z = \frac{35 - 42.1}{6.6}

z = \frac{-7.1}{6.6}

z = 1.0758

For the actress:

z = \frac{54 - 34.3}{10.1}

z = \frac{19.7}{10.1}

z = 1.950

Comparing both z values;

The actress has the more extreme age because

  • <em>It has a positive z value</em>
  • <em>Its z value is greater than that of the actor</em>

<em></em>

Sin 3/5<br> 4/5<br> 3/4<br> 5/4
julsineya [31]

Answer:

\boxed{\frac{3}{5}}

Step-by-step explanation:

The trigonometric functions are described as follows:

sin = \frac{opposite}{hypotenuse}\\\\cos = \frac{adjacent}{hypotenuse}\\\\tan = \frac{opposite}{adjacent}

Using reference angle ∠A, use the sin trigonometric function. This will be the side opposite (cannot be the hypotenuse) of ∠A over the side adjacent (cannot be the hypotenuse).

The side opposite of ∠A is 3. The hypotenuse of the triangle is 5.

\boxed{\frac{3}{5}}  is the final answer!
