Answer:

1 cm : 2m

1 cm = 2m

118m

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

18 / 9 = 2 : 1

59 x 2 = 118

Write the general equation for the circle that passes through the points: (1, 7) (8, 6) (7, -1)
Naddika [18.5K]

Answer:

x^{2} +y^{2} +(-8)\times x+ (-6)\times y = 0  

Step-by-step explanation:

General equation of circle is x^{2} +y^{2} +2\times g \times x+2\times f\times y+c = 0   ---------------------(1)

This circle passes through the given three points, (1,7) , (8,6) and (7,-1).

Substitute (1,7) in (1),

1 + 7^{2} +2\times g\times 1 + 2\times f\times 7 +c =0

2g + 14f + c = -50     -------------(2)

Substitute (8,6) in (1),

8^{2} + 6^{2} +2\times g \times 8+2\times f\times 6 +c=0

16g + 12f + c = -100    -----------(3)

Substitute (7,-1) in (1),

7^{2} + (-1)^{2} +2\times g \times 7+2\times f\times (-1) +c=0

14g - 2f + c = -50    ---------------(4)

Solving (2),(3) amd (4) simultaneously,

g = -4

f = -3

c = 0

Equation of circle is

x^{2} +y^{2} +(-8)\times x+ (-6)\times y = 0

The advertising department of a nationally circulated magazine wishes to estimate the mean age of its subscribers within 0.5 yea
zhenek [66]

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Margin of error = 0.5 years

Standard deviation = 5

At 90% confidence, z = 1.645

We need to find the minimum size of the sample they must take.

So,

n=(\dfrac{z\sigma}{E})^2\\\\n=(\dfrac{1.645\times 5}{0.5})^2\\\\n=270.6\\\\n\approx 271

Hence, Option 'd' is correct.
