Answer:
A. Being above 180 centimeters and having black hair are independent of each other.
Step-by-step explanation:
These are instinctively two characteristics that are not related and the table data proves it.
If they were dependent, you would have only people with black hair above 180 cm, and all people with black hair would be above 180 cm.
You can be above 180 cm and have black, brown or blonde hair. The table shows a proportion of people > 180 cm about equal (around 30% of the sampling) for each hair color.
And people above 180 cm only represent 30% of the people with black hair.
It looks like you want to compute the double integral
over the region <em>D</em> with the unit circle <em>x</em> ² + <em>y</em> ² = 1 as its boundary.
Convert to polar coordinates, in which <em>D</em> is given by the set
<em>D</em> = {(<em>r</em>, <em>θ</em>) : 0 ≤ <em>r</em> ≤ 1 and 0 ≤ <em>θ</em> ≤ 2<em>π</em>}
and
<em>x</em> = <em>r</em> cos(<em>θ</em>)
<em>y</em> = <em>r</em> sin(<em>θ</em>)
d<em>x</em> d<em>y</em> = <em>r</em> d<em>r</em> d<em>θ</em>
Then the integral is
Scale factor is simply the ratio of sides of two corresponding figures
<em>The estimated scale factor is 1.5</em>
From the question, we have:
- The actual figure is AB
- The dilation is AC
- The center of dilation is A
So, the scale factor (S) would be:
The actual measurements are not given; so, we will make use of estimates
The estimates to use are:
So, the scale factor is:
Hence, the estimated scale factor is 1.5
