Answer: $scale\ factor=2.5$

Step-by-step explanation:

First, it is important to know that the scale factor is defined as a ratio of two corresponding side lengths of similar figures.

Similar figures are defined as those figures in which the ratio of their corresponfing side lengths are equal and their corresponding angles are congruent (which means that they have the same measure).

In this case, you know that the rectangles given in the picture are similar.

Therefore, you can find the scale factor that was applied to the first rectangle to get the resulting image, dividing the lenghts of their corresponding sides.

Then, this is:

$scale\ factor=\frac{7.5}{3}\\\\scale\ factor=2.5$

zheka24 [161]

Answer:

False

Step-by-step explanation:

Confidence intervals provide a range for a population parameter at a given significance level. The parameter can be mean, standard deviation etc.

In this example population is the prices of the rents of all the unfurnished one-bedroom apartments in the Boston area

significance level is 95%. Thus, the chance being the true population parameter in the given interval is 95%.

But, "This interval describes the price of 95% of the rents of all the unfurnished one-bedroom apartments in the Boston area." statement is false because the population parameter is missing. Confidence interval may describe population mean for example but it does not describe the <em>whole</em> population.

Scientific notation uses expression which gives easy access of order. The scientific notation of given number is: Option A: 1.6E-8

<h3>How to convert a number to scientific notation?</h3>

It is usually of the form $a.bc.. \times 10^k$ exponent of 10 starts)

(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)

This notation is used to get some idea of how large or small a number is in terms of power of 10.

<h3>What are some basic properties of exponentiation?</h3>

If we have $a^b$ then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

$a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}$

The given number is converted in scientific notation as:

$0. 000000016 = \dfrac{1.6}{100000000} = \dfrac{1.6}{10^8} = 1.6 \times 10^{-8} = 1.6 E -8$

Thus, the scientific notation of given number is: Option A: 1.6E-8
