Find the length of ST

Mathematics
1 answer:
Andru [333]3 years ago
3 0

Answer:

ST = 12

Step-by-step explanation:

By AA Similarity, triangles ASR and EST are similar.

The ratio of the lengths of the sides of triangle ASR to those of EST is 6/8 or 3/4.

\dfrac{SR}{ST} = \dfrac{3}{4}

Also,

SR + ST = 21

By a rule of proportions, you get

\dfrac{SR + ST}{ST} = \dfrac{3 + 4}{4}

\dfrac{21}{ST} = \dfrac{7}{4}

7ST = 4 \times 21

7ST = 84

ST = 12

Raquel and Van live in two different cities. As part of a project, they each record the lowest prices for a gallon of gas at gas
mylen [45]

Based on the information given, the true statement true about their gas-price data is A. Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

<h3>Solution to the gas-price data.</h3>

It should be noted that a standard deviation simply measures how dispersed the data will be in relation to the mean.

From the complete question, the mean of Raquel's data is given as 3.42 while the standard deviation is given as 0.07. On the other hand, the mean of Van's data is given as 3.78 while the standard deviation is given as 0.23.

Therefore, it can be deduced that Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
