Answer: The value of 'x' is 31.

Step-by-step explanation: As shown in the modified attached figure, AC and BD are two intersecting chords, where ∠CBD = x° and ∠CAD = 31°.

We are to find the value of 'x'.

The measures of the angles on the circumference of a circle subtended by the same chord (arc) are equal.

In the attached figure, ∠CBD and ∠CAD are angles subtended at the circumference of the circle by the same arc CD.

Therefore, we must have

$\angle CBD=\angle CAD\\\\\Rightarrow x^\circ=31^\circ.$

Therefore, the value of 'x' is 31.

Thus, (B) is the correct option.

According to a survey, 15% of city workers take the bus to work. Donatella randomly surveys 10 workers. What is the probability

Andru [333]

Answer:0.001

x=the number of workers taking the bus to work

p= probability of success =(15/100) = 0.15

q= probability of failure =1- p = 0.85

P(X=6) = 10C6(0.15)^6(0.85)^4

= 0.001

A rectangular solid with a square base has a volume of 4096 cubic inches - determine the dimensions that yield the minimum surfa

Bumek [7]

Answer:

side of base, a = 10.1 inches, height, h = 40.1 inches

Step-by-step explanation:

Volume of rectangular solid, V = 4096 cubic inches

Let the side of base is a and the height is h.

$V = a^2h\\\\4096 = a^2 h ..... (1)$

surface area of the solid

$S = 2a^2 + 4 ah \\\\S = 2a^2 + 4 \times a \times \frac{4096}{a^2} from (1)\\\S = 2a^2 + \frac{4096}{a}\\\\\frac{dS}{da}= 4 a - \frac{4096}{a^2}\\\\4 a - \frac{4096}{a^2} = 0 \\\\a^3 = 1024\\\\a =10.1 inches$

So, h = 40.2 inches
