If a spinner for a game is spun once, there is a 25% chance it will land on
bonufazy [111]

Answer:

Pr = 0.6

Step-by-step explanation:

Given

Let

O \to Orange

So:

P(O) = 25\% --- probability of O

n=2 --- Number of spin

Using the complement rule, the probability that a spin will not land on orange is:

P(O') = 1 - P(O)

P(O') = 1 - 25\%

Express as decimal

P(O') = 1 - 0.25

P(O') = 0.75

On two spins, the probability that it will not land on orange is:

Pr = P(O') * P(O')

So, we have:

Pr = 0.75* 0.75

Pr = 0.5625

<em></em>Pr = 0.6<em> --- approximated</em>

Find the distance between xequals[Start 2 By 1 Matrix 1st Row 1st Column 8 2nd Row 1st Column negative 5 EndMatrix ]and yequals[
kherson [118]

Answer:

Distance =√(x₁ - y₁)²+ (x₂ - y₂)² = √97 = 9.85

Step-by-step explanation:

The Matrix X and Y could also be referred to as vectors in Rⁿ dimensions.

if Vector X = ( x₁ , x₂)   and  Vector  Y = (y₁ , y₂)

then, Distance (X-Y) = ||X-Y|| = √(x₁ - y₁)²+ (x₂ - y₂)²

where, x₁ = 8, x₂ = -5   and  y₁ = -1 , y₂ = -9

Distance = √(8 - (-1))²+ (-5 - (-9))² = √9² + 4² =√97 = 9.85

If 588 digits were used to number the pages of a book how many pages are in this book.
iVinArrow [24]

Answer: 232 pages

Step-by-step explanation:

Total digits = 588

1 digit page number:

1 to 9 = 1 × 9 = 9

Number of pages = 9/1 = 9

2 - digit page number :

10 - 99 = 2 × 90 = 180

Number of pages = 180/2 = 90

3 - digit page number :

588 - (9 + 180) = 588 - 189 = 399

Number of pages with 3 - digits = 399/3 = 133

Therefore, the total number of pages the book has is :

(9 + 90 + 133) = 232 pages

so, the area is

A = a²

A = 24²

A = 24 × 24

A = 576 m²
