The  determined value of mean µ is 1.3 and variance σ² is 0.81.

What is mean and variance?

  • A measurement of central dispersion is the mean and variance. The average of a group of numbers is known as the mean.
  • The variance is calculated as the square root of the variance.
  • We can determine how the data we are collecting for observation are dispersed and distributed by looking at central dispersion.

The table is attached as an image for reference.

Mean µ = ∑X P(X)

         µ = 1.3

Variance (σ² ) = ∑ X² P(X)- (µ)²

                       = 2.5-(1.3)²

                (σ² ) = 0.81

The  determined value of mean µ is 1.3 and variance σ² is 0.81.

Ivenika [448]

Complete question :

designs a board game in which a card is drawn on each turn. • A blue card means move forward 4 squares. • A red card means move back 6 squares. Liam suggests adding some other cards to Sia's game Part A Liam explains that drawing a yellow card is equivalent to drawing a blue card followed by a red card. How many spaces forward or backward does a player move after drawing a yellow card? Justify your answer.

Answer:

2 squares backward

Step-by-step explanation:

Given the rule :

Blue card = 4 squares forward

Red card = 6 squares backward

Yellow card = drawing a blue followed by a red

Spaces moved after drawing a yellow card:

Yellow equals :

Blue = + 4 squares ; then

Red = - 6 squares

Net total movement :

Blue + red

+4 + (-6)

4 - 6

- 2

2 squares backward

Given that F( x ) = x 2 + 2, evaluate F(1) + F(5).
stealth61 [152]

Hi there! :)

Answer:

\huge\boxed{f(1) + f(5) = 30}

Given:

f(x) = x^{2} + 2

Evaluate f(1) + f(5)

Solve for each:

f(1) = (1)^{2} +  2 = 3

f(5) = (5)^{2} + 2 = 27

27 + 3 = 30
