How do I solve this question?
nirvana33 [79]
First subtract 11b from both sides and then 11b would cancel out and the 14 would be 3b and then you subtract 3 from both sides and so it would be 3 so you divide 3b by 3 so it would be 3 greater than or equal to b.

distribution below?

Grade(X)_____ 1_____2_____3_____4_____5

Frequency____3 _____5____ 9 ____ 5 ____ 3

P(X) : _______ 0.1 ___0.2 ___0.4 ___ 0.2 __0.1

Answer:

3

Step-by-step explanation:

Given the probability distribution :

Grade(X)_____ 1_____2_____3_____4_____5

Frequency____3 _____5____ 9 ____ 5 ____ 3

P(X) : _______ 0.1 ___0.2 ___0.4 ___ 0.2 __0.1

The mean of the distribution :

Σ(X * P(X)) :

(1*0. 1) + (2 * 0.2) + (3 * 0.4) + (4 * 0.2) + (5 * 0.1)

0.1 + 0.4 + 1.2 + 0.8 + 0.5

Given two sets of polar coordinates that could be used to play the given point
topjm [15]

Answer:  a.  (2.5, 300°)  and  (-2.5, 120°)

               b.  (4, 270°)    and   (-4, 90°)

<u>Step-by-step explanation:</u>

Polar coordinates are written as (r, θ)    where

  • r is the radius
  • θ is the angle

In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)

You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)

                                                                           ↓

                                                                    (300 - 180)

In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)

You can also list the radius as -4 at angle 90° --> (-4, 90°)

                                                                      ↓

                                                                (270 - 180)
