Let's see

$\\ \rm\dashrightarrow \dfrac{9}{x}=\dfrac{24}{12}$

$\\ \rm\dashrightarrow \dfrac{9}{x}=2$

$\\ \rm\dashrightarrow x=\dfrac{9}{2}$

$\\ \rm\dashrightarrow x=4.5$

Let X denote the number of bars of service on your cell phone whenever you are at an intersection with the following probabiliti

ZanzabumX [31]

Answer:

a. $P(2 \leq X \leq 3) = 0.5$

b. $P(X \geq 1) = 0.9$

c. $P(X < 2) = 0.25$

d. $P(X > 3) = 0.25$

Step-by-step explanation:

We are given the following distribution:

$P(X = 0) = 0.1$

$P(X = 1) = 0.15$

$P(X = 2) = 0.25$

$P(X = 3) = 0.25$

$P(X = 4) = 0.15$

$P(X = 5) = 0.1$

a. Two or three bars

$P(2 \leq X \leq 3) = P(X = 2) + P(X = 3) = 0.25 + 0.25 = 0.5$

Thus:

$P(2 \leq X \leq 3) = 0.5$

b. At least one bar

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1 = 0.9$

Thus:

$P(X \geq 1) = 0.9$

c. Fewer than two bars

$P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.15 = 0.25$

Thus:

$P(X < 2) = 0.25$

d. More than three bars

$P(X > 3) = P(X = 4) + P(X = 5) = 0.15 + 0.1 = 0.25$

Thus:

$P(X > 3) = 0.25$

A right triangle in which one acute angle is a reference angle for a 115 degree angle in standard position intersects the unit c

Ratling [72]

Answer:

$\cos (115\degree)=-0.423$

Step-by-step explanation:

The parametric equations of a circle is

$x=r\cos \theta$ and $y=r\sin \theta$

The radius of the unit circle is 1 unit.

This implies that any point on the unit circle is represented by:

$x=\cos \theta$ and $y=\sin \theta$

where $\theta$ is the angle in standard position,

From the question, the given angle in standard position is $115\degree$ .

This angle intersects the unit circle at $x=-0.423$

But $x=\cos \theta$

We substitute $\theta=115\degree$ and $x=-0.423$

This implies that: $\cos (115\degree)=-0.423$
