Answer:

x = 19°

Step-by-step explanation:

Refer the attached figure

Given : ∠ACB = 71°

            ∠BAC = x°

Thales' theorem : If A, B, and C are distinct points on a circle where the line AC is a diameter, then the angle ∠ABC is a right angle.

So, by Thale's theorem ∠ABC is a right angle in the given figure

i.e.∠ABC = 90°

In ΔABC ,

To find x we will use angle sum property of triangle

Angle sum property of triangle : Sum of all angles is 180°

⇒∠BAC+∠ABC+∠ACB = 180°

⇒x°+90°+71° = 180°

⇒x°+161° = 180°

⇒x° = 180°-161°

⇒x° =19°

∠BAC = x° =19°

Thus x = 19°

Hence Option 1 is correct .

She would have to miss 1 or 2 because 1/6 of 18 is 3 so less than 3 is 2 or 1

hope that helps!

In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft. For a group of 1013 adults, the mea
Kazeer [188]

Answer:

Mean = 344

Step-by-step explanation:

Given

Population =  1013

Let p represents the proportion of those who worry about identity theft;

p = 66\%

Required

Mean of those who do not worry about identity theft

First, the proportion of those who do not worry, has to be calculated;

Represent this with q

In probability;

p + q = 1

Make q the subject of formula

q = 1 - p

Substitute p = 66\%

q = 1 - 66\%

Convert percentage to fraction

q = 1 - 0.66

q = 0.34

Now, the mean can be calculated using:

Mean = nq

Where n represents the population

Mean = 1013 * 0.34

Mean = 344.42

Mean = 344 (Approximated)
