the LSRL after an exponential transformation is lof y=0.986 + 3.149x. what is the exponential form of the regression
dolphi86 [110]

The exponential form of the regression 9.68(1409)^x .

An exponential function is described as a characteristic with a nice regular other than 1 raised to a variable exponent. A function is evaluated with the aid of solving at a specific input price. An exponential model can be found when the boom fee and preliminary cost are recognized.

As Harvard commercial enterprise review put it, “The incremental mindset makes a speciality of making something higher, at the same time as the exponential mindset makes a speciality of making something distinct. Incremental is glad with just five percent.

The exponential characteristic is a mathematical feature denoted by using f(x)=exp or e^{x}. Until in any other case specific, the term commonly refers to the fine-valued function of a actual variable, despite the fact that it is able to be extended to the complicated numbers or generalized to other mathematical items like matrices or Lie algebras.

A shopper at a local supermarket spent the following amounts in her last eight trips to the store: $32.92 $14.14 $30.80 $28.34 $
alexdok [17]

Answer:

$75.58

The amount spent of $75.58 is most likely an outlier

Step-by-step explanation:

An outliers are unusual values in a dataset, they are data values that are extremely higher or extremely lower when compared to the other values in a data (data points that are far from other data points)

For the case above, give a dataset;

$32.92 $14.14 $30.80 $28.34 $75.58 $36.33 $33.51 $22.94

$75.58 is extremely far from other value. So $75.58 is an outlier in the given dataset.

In the diagram below, GH is parallel to DE . If GH is 3 more than EH FH=10, and DE=12 find the length of EH. Figures are not nec
steposvetlana [31]

Answer: 5

Step-by-step explanation:

Since \overline{GH} \parallel \overline{DE}, by the corresponding angles theorem, \angle FGH \cong \angle FDE, \angle FHG \cong \angle FED. This means \triangle FGH \sim \triangle FDE by AA.

As corresponding sides of similar triangles are proportional,

\frac{10}{x+3}=\frac{10+x}{12}\\(10)(12)=(10+x)(x+3)\\120=x^{2}+13x+30\\x^{2}+13x-90=0\\(x+18)(x-5)=0\\x=-18, 5
However, as distance must be positive, we consider the positive solution, x=5.

Therefore, the answer is <u>5</u>
