Part A - Construct a circle of any radius, and draw a chord on it. The construct the radius of the circle that bisects the chord
Julli [10]

Answer:

It can be concluded that the intersection of a chord and the radius that bisects it is at right angle. The two are perpendicular.

Step-by-step explanation:

i. Construct the required circle of any radius as given in the question, then locate the chord. A chord joins two points on the circumference of a circle, but not passing through its center.

ii. Construct the radius to bisect the chord, dividing it into two equal parts.

Then it would be observed that the intersection of a chord and the radius that bisects it is at right angle. Thus, the chord and radius are are perpendicular to each other.

The construction to the question is herewith attached to this answer for more clarifications.

What is the domain for each function below? Choose the correct inequality symbol from the drop down menu and fill in the blank w
erik [133]

Answer:

x \le 3

x \ge 0

Step-by-step explanation:

The functions, missing from the question are:

f(x) = \sqrt{3 - x

f(x) = \sqrt{3 x

Required

Determine the domain

To get the domain, means we want to get the possible values of x.

(a)

f(x) = \sqrt{3 - x

Equate 3 - x to 0

3 - x = 0

Solve for x

-x = -3

x = 3

From the calculated value of x above;

When x exceeds 3; f(x) = undefined

So: the domain is:

x \le 3

(b)

f(x) = \sqrt{3x

Equate 3x to 0

3x = 0

Solve for x

x = 0

From the calculated value of x above;

When x falls below 0; f(x) = undefined

So: the domain is:

x \ge 0

1. Sam rolls a fair dice and flips a fair
kicyunya [14]

Answer:

Mark brainliest pls

Step-by-step explanation:

People have given you correct answers but not explained why, perhaps because it seems so obvious.

One of Bayes laws of probability says that if two events e1 and e2 are independent (unrelated), then the probability of both happening together is the product of their individual probabilities.

The die and the coin are independent events. Each is a 50% chance (odd number on a die, heads on a coin). Thus the probability of both happening together is 50% * 50% = 25%.
