Answer:

la alianza: 225

la alternativa: 180

blanco: 405

Step-by-step explanation:

El número total de personas en la ciudad es 810

La fracción de personas que eligieron la alianza es \dfrac{5}{18}

La cantidad de personas que eligieron la alianza es \dfrac{5}{18}\times 810=225

La fracción de personas que eligieron la alternativa es \dfrac{2}{9}

La cantidad de personas que eligieron la alternativa es \dfrac{2}{9}\times 810=180

El número de personas que eligieron el espacio en blanco fue 810-(225+180)=405.

A cylinder has height of 7 inches and a base with a diameter of 9 inches.
bekas [8.4K]

Answer:

527.6 cubic inches

Step-by-step explanation:

The volume of a cylinder is represented by the formula V = \pi r^{2} h, where r represents the radius of the base and h represents the height.

In this question, the diameter is given as 9 inches. Since the radius is half the diameter, the radius will be 4.5 inches.

Substituting in the values and solving, we get:

V =9 \pi (4.5)^{2}\\V = 9\pi(20.25)\\V = 182.25\pi\\V = 572.6

The Volume will be 527.6 cubic inches

2x-y<-3
timama [110]

Answer:

y > 2x + 3

Step-by-step explanation:

Okay, first let's simplify the equation by understanding the form.

y = mx + b is the form.

Currently we have 2x - y < -3, So we can subtract 2x on both sides to get

-y < -2x - 3

Let's multiply each term by -1 to get

y < 2x + 3, but wait! We have to flip the sign!

The answer is :

y > 2x + 3

Combining probabilities is a function of _____.
Romashka-Z-Leto [24]
I think the correct answer from the choices listed above is the second option. Combining probabilities is a function of mutually exclusive events. Joint probability<span> is a measure of two events happening at the same time, and can only be applied to situations where more than one observation can be occurred at the same time.</span>
