The figures below are similar.
Dafna1 [17]

Answer:

  a) 2.5

  b) 6.25

Step-by-step explanation:

For similar figures, the ratio of any corresponding linear dimensions is the same. The ratio of areas is the square of that.

<h3>Application</h3>

The ratio of linear dimensions, larger to smaller, is ...

  (30 yd)/(12 yd) = 2.5

<h3>a) Perimeter</h3>

Perimeter is a linear dimension, the sum of side lengths. The ratio of perimeters is 2.5.

<h3>b) Area</h3>

The ratio of areas, larger to smaller, is the square of the scale factor for side lengths:

  (2.5)² = 6.25

The ratio of the areas of the larger to smaller figure is 6.25.

There are 318 teachers at a college. Among a sample of 115 teachers from this college, 67 have doctorates. Based on this sample,
Fofino [41]

Answer: \dfrac{67}{115} or 0.5826

Step-by-step explanation:

Given : The total number of teachers in at a college = 318

In sample of n= 115 teachers from this college, the number of teachers with doctorates  : x=67

Then, the sample proportion of teachers at this college with doctorates

=\hat{p}=\dfrac{x}{n}\\\\=\dfrac{67}{115}=0.582608695652\approx0.5826  

Since the sample proportion is the best estimate of the population proportion.

Therefore , the estimated the population proportion of teachers at this college with doctorates = \hat{p}=\dfrac{67}{115}\  or\ 0.5826
