kherson [118]

Answer:

A. Continuous, B. Discrete, C. Continuous, D. Continuous, E. Continuous.

Step-by-step explanation:

A. Area is a continuous unit. Then, the floor area of a kitchen is a continuous random variable.

B. Quantity is a discrete unit. Then, the number of bacteria in a particular cubic centimeter of drinking water is a discrete random variable.

C. The money amount is a continuous unit. Then, the dollar amount of the change in my pocket is a continuous random variable.

D. The pressure is a continuous unit. Then, the barometric pressure at a given location is a continuous random variable.

E. Time is a continuous unit. Then, the difference in reaction time to the same stimulus before and after training is a continuous random variable.

An isosceles triangle ABC has legs of length 24 and a vertex angle that measures 36º . Determine the length of its base, BC , to

iris [78.8K]

Answer: $BC=14.8$

Step-by-step explanation:

By definition, an Isosceles triangle has two equal sides and its opposite angles are congruent.

Observe the figure attached, where the isosceles triangle is divided into two equal right triangles.

So, in this case you need to use the following Trigonometric Identity:

$sin\alpha =\frac{opposite}{hypotenuse}$

In this case, you can identify that:

$\alpha =\angle BAD=\angle CAD=18\°\\\\opposite=BD=CD=x\\\\hypotenuse=AB=AC=24$

Substituting values, and solving for "x", you get:

$sin(18\°)=\frac{x}{24}\\\\24*sin(18\°)=x\\\\x=7.416$

Therefore, the length of BC rounded to nearest tenth, is:

$BC=2(7.416)=14.8$

Use the equation below to find y, if m= 8 and x=6.<br> y=mx <br> y=?

Lunna [17]

Answer:

The value of y is 48.

Step-by-step explanation:

You have to substitute the values into the equation :

$y = mx$

$let \: m = 8,x = 6$

$y = 8 \times 6$

$y = 48$
