Answer:

D=√13(Decimal: 3.605551)

3.6

Step-by-step explanation:

Let's find the distance between your two points.

(−5,5);(−2,3)

(x1,y1)=(−5,5)

(x2,y2)=(−2,3)

Use the distance formula:

D=√(x2−x1[tex])^{2}[/tex]+(y2−y1[tex])^{2}[/tex]

=√(−2−−5[tex])^{2}[/tex]+(3−5[tex])^{2}[/tex]

=√(3[tex])^{2}[/tex]+(−2[tex])^{2}[/tex]

=√9+4

=√13

D=√13(Decimal: 3.605551)

The correct option is (a) i.e. Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more accurate predicted values will be.

What is Regression analysis?

A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It can be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.

Although there are non-linear regression techniques for more complex data and analysis, simple linear regression and multiple linear regression are the two fundamental types of regression. While multiple linear regression employs two or more independent factors to predict the outcome, simple linear regression just uses one independent variable to explain or predict the outcome of the dependent variable Y. (while holding all others constant).

Professionals in other industries, including banking and investment, might benefit from regression. Regression can also aid in predicting sales for a business based on external factors like the weather, past sales, GDP growth, and other variables. A popular regression model in finance for valuing assets and calculating capital expenses is the capital asset pricing model (CAPM).

An 11 digit number which is a solution to the problem Giveb is 32,561,100,000

All we have to do is write out an 11 digit number such that the value in the 1 million place is 10 times the value in the 100,000 place.

32,561,100,000

Writing the value given in expanded form :

3 in 10 billion place = 30,000,000,000

2 in one billion place = 2,000,000,000

5 in 100 million place = 500,000,000

6 in 10 million place = 60,000,000

1 in 1 million place = 1,000,000

1 in 100 thousand place = 100,000

Comparing the value in the 1 million place and that in the 100 thousand place :

1,000,000 / 100,000 = 10

This means that the value in the 1 million place is 10 times the value in the 100,000 place.

We will need 85cc of 20% saline solution for the mixture

Let the amount of 20% saline solution be "a"

If a nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution, then the finished product will be 40 + a cc which containing 36% saline solution.

The saline content will therefore be expressed as:

(70% of 40)+20% of a = 36% of (40 + a)

0.7*40 + 0.2a = 0.36(40 +a)

28 + 0.2a = 14.4+0.36a

28 - 14.4 = 0.36a - 0.2a

13.6= 0.16a

a = 13.6/0.16

a = 85

This means that we will need 85cc of 20% saline solution for the mixture

Answer:

The mean is 70.8.

Step-by-step explanation:

Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.

So, we have :: 60, 67, 71, 76, 80.

These numbers added together = 354.

There are 5 numbers listed.

354 / 5 = 70.8.

Q) [35 - (8 + 2) × 3] = ?

→ 35 - {(8 + 2) × 3}

→ 35 - {10 × 3}

→ 35 - 30

→ 5 is the correct answer.

Step-by-step explanation:

Hi there!

Given;

f(x) = 5x-1

Now; Simply keep the value of x in the given function.

f(1) = 5*1-11

= -6

Again;

f(3) = 5*3-11

= 15-11

= 4

Therefore, f(1) = -6 and f(3) = 4.

Answer:

They are similar.

Step-by-step explanation:

123 + 36 + x = 180

159 + x = 180

(159 - 159) + x = 180 - 159

x = 21

36 + 21 + x = 180

57 + x = 180

(57 - 57) + x = 180 - 57

x = 123

CDE = 123 + 36 + 21

ABC = 123 + 36 + 21
