Mathematics

Answer:

x = 6

Step-by-step explanation:

The segment from O to the chord is a perpendicular bisector.

The triangle formed is right with legs x and 8 and hypotenuse 10

Using Pythagoras' identity in the right triangle, then

x² + 8² = 10²

x² + 64 = 100 ( subtract 64 from both sides )

x² = 36 ( take the square root of both sides )

x = \sqrt{36} = 6

Answer:

Step-by-step explanation:

diameter = 20

radius  = 10 units

Length of Chord = 16 units

The perpendicular from the center to a chord, bisect the chord.

So, base = 16/2 = 8units

Use Pythagorean theorem.

x² + 8² = 10²

x² + 64 = 100

x² = 100 -64

x² = 36

x = √36 = √6*6

x = 6 units

In a sample of 32 city residence, 24 reported that they take vitamin C supplement daily. There are 46,480 residence in the city.
Andreyy89

Answer:

34,860

Step-by-step explanation:

In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75

0.75 in  percentage is 75%. This means 75% of the residents in sample take Vitamin C.

We can expect the same percentage of people in entire population to take Vitamin C.

Total population of city = 46480

Expected number of residents who take vitamin C in the city = 75% of 46480

= 0.75 x 46480

= 34860

This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.

Answer:

c) x = 20, angle COD = 70 °

Step-by-step explanation:

(x+50)° + 90° +20° = 180°

x + 160° = 180°

x = 180°- 160°

x = 20

Angle COD = (x+50)° = (20 +50)° = 70°
