x = length of one side.

1,232in^2 = x^2

Take the sqrt of both sides.

35.1 in = x

The length of one side = 35.1 in

Step-by-step explanation:

We know that,

area of square = a²

→ 1,232 = a²

→ a = √1232

→ a = 35.0 in

Nearest 10th = 35.1 in

Write as a product of two polynomials.<br> a(b–c)+d(c–b)
Naya [18.7K]

Answer:

(b - c)(a - d)

Step-by-step explanation:

Given

a(b - c) + d(c - b) ← factor out - 1

= a(b - c) - d(b - c) ← factor out (b - c) from each term

= (b - c)(a - d)

Write the standard equation of a circle with a center (2,-8) and radius 9
Anna11 [10]

The standard equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have:

(2, -8) → h = 2, k = -8

r = 9

Substitute:

(x-2)^2+(y-(-8))^2=9^2\\\\(x-2)^2+(y+8)^2=81

Thirty-two percent of workers in Troberca City are college graduates. You randomly select 50 workers and ask them is he or she i
Gnoma [55]

The correct option is B) 67.4%

<h3>What is the z- score table?</h3>

A standard normal table (also called the unit normal table or z-score table) is a mathematical table for the values of ϕ, indicating the values of the cumulative distribution function of the normal distribution. Z-Score, also known as the standard score, indicates how many standard deviations an entity is, from the mean.

Given here, P(probability that a worker is a college graduate) = 32%

                                                                                                      = 0.32

q (probability that a worker is not a college graduate) is 1-0.32 = 0.68  

now μ(mean) = n×p

                      = 50×0.32

                      = 16

Again standard deviation σ = \sqrt{npq\\}

                                           σ = \sqrt{50\cdot 0.32\cdot 0.68}

                                           σ = 3.2985

now P(x<17.5) = P((x-μ)/σ <(17.5-16)/3.2985)

                      = P(z<0.45)  

                      = 0.674 [using z table]

                      = 67.4%

Hence option 2 is the correct answer
