<span>Circle 1 is centered at (5, 8) and has a radius of 8 cm
</span><span>
</span>Circle 2 is centered at (1, −2) and has a radius of 4 cm

To transform circle 1 to circle 2 ⇒⇒ we need to transform (5,8) to (1,-2)
<span>the transformation rule (x-4 , y-10) </span><span>
</span><span>because  5-1 = 4  and   8-(-2) = 10
</span>
<span>while circle 1 has a radius = 8 and the circle 2 has a radius = 4 cm
</span><span>
</span>So, the <span>dilation factor = 4/8 = 0.5
</span><span>
</span>
<span>The correct answer is :
</span>
<span>The circles are similar because you can translate Circle 1 using the transformation rule ( x-4 , y-10) and then dilate it using a scale factor of 0.5</span>

At a university, 12% of students smoke. Calculate the expected number of smokers in a random sample of 140 students from this un
Masteriza [31]

Answer:

a) The expected number of smokers in a random sample of 140 students from this university is 16.8 smokers.

b) No, it is unlikely that smoking habits and waking up early to go to the gym on Saturday are independent.

Step-by-step explanation:

To calculate the expected numbers of smokers in a sample with size n=140 and proportion p=12%, we use the expected value of the binomial distribution:

E(x)=n\cdot p=140\cdot 0.12=16.8

The expected number of smokers in a random sample of 140 students from this university is 16.8 smokers.

If we take a sample at the opening of the gym, the sample is not expected to be representative of the population of the students. Most of the students that go to the gym usually have healthy habits, so the proportions of smokers is expected to be lower than the average of the university population.

Elden [556K]

Answer:

36.4mi

Step-by-step explanation:

The boat sailed two legs of a right-angled triangle.

The distance from the starting point is the hypotenuse of the triangle.

d = √(35² + 10²)

  = √(1225 + 100)

  = √1325

  = 36.4 mi
