Figure I and Figure II are similar figures,
ELEN [110]

The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,

\frac{ST}{EF}=\frac{WR}{CD}

Thus the option H is the correct option.

To find the correct proportion we need to know about the properties of slimier polygon.

<h3>What are the properties of similar polygon?</h3>

Two polygons are said to be similar or congruent pentagon-

The corresponding angle of two pentagons are congruent.

The ratio of corresponding sides is same for all the sides.

The figure given in the problem of similar two polygons with six sides.

Rearrange the second figure as shown in figure.

As for the similar polygons, the ratio of corresponding sides is same for all the sides.

Thus the sides shown in the two rearranged figure must be same. Therefore,

\frac{ST}{EF}=\frac{WR}{CD}

Hence the correct proportion is,

\frac{ST}{EF}=\frac{WR}{CD}

Thus the option H is the correct option.

first number

5

then the rest

7

equal

5.7

There's <u>three</u> zeros <u>behind</u> the number 5 which mean it will be -3

\times  {10}^{ - 3}

final answer

5.7 \times {10}^{ - 3}

another example and it will be clear

0.0000403

first number

4

then the rest

03

equal

4.03

Paulo catches a 7.45 am tram to school. During a period of 79 days, he arrives at school on time 53 occasions. Estimate the prob
lawyer [7]

Answer:

<em>On time: 0.67</em>

<em>Late: 0.33</em>

Step-by-step explanation:

<u>Probabilities</u>

One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).

The probability can be estimated with the formula:

\displaystyle P=\frac{e}{n}

And the probability that the event doesn't occur is

Q = 1 - P

Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:

\displaystyle P=\frac{53}{79}

P = 0.67

And the probability he arrives late is:

Q = 1 - 0.67 = 0.33
