0.75r+0.75(3.20)=0.75(r+3.20)

So the answer is A. The product of 0.75 with the sum of r and 3.20

Use the given information and a calculator to find to the nearest tenth of a degree

Schach [20]

Answer:

111.4 degrees

Step-by-step explanation:

Let's write cos x = -0.3646. Or, look up the symbols chart at the bottom of your page and click on Ф to obtain this character: cos Ф = -0.3646.

If Ф is in Quadrant III, then the adjacent side is negative and the hypotenuse is positive.

-1

Type this into your calculator: cos -0.3646. Result: 1.934 (radians)

This converts to degrees as follows:

1.934 rad 180 degr

--------------- * --------------- = 111.4 degrees. Note that this angle is in QIII.

1 π rad

Given two events A and B of a sample set where P[A] = .20 P[not B] = .40 P[B|A] = .25 What is P[A or B]?

kobusy [5.1K]

Answer:

Given two events A and B of a sample set :-

P[A] = 0.20

P[not B]=0.40

$P[B/A]=0.25$

To find P[A or B]:

$P[A or B] = P[A] + P[B] - P[A \cap B]$ ......[1]

Calculate for $P[B]$ and $P[A \cap B]$

P[B] = 1- P[not B]

Substitute the value P[not B] we get;

P[B] = 1-0.40 = 0.60

$P[A \cap B] = P[B/A] \cdot P[A]$

Substitute the given values we get;

$P[A \cap B] = 0.25 \cdot 0.20 = 0.05$

Then;

$P[A or B] = 0.20+0.60-0.05 = 0.80-0.05 =0.75$

Therefore, the value of P[A or B] is, 0.75.
