Answer:

  A = 4, B = 3

Step-by-step explanation:

You require that ...

  0.30 × A = 0.40 × B

Then ...

  B = (3/4)A . . . . . divide by 0.40

Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).

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)

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.

Answer:

x = 8

y = -6

Step-by-step explanation:

Vertical lines have a undefined slope and horizontal lines have a slope of 0. You'll write the equations for these types of lines like this.

Since we don't have two points, we are going to have to graph the points and draw a line to find the intercepts. The graphs will be shown below. From finding out what the intercepts are, we can substitute the according values into the formula shown above.

x = 8

y = -6

Answer:

12.6

Step-by-step explanation:

The square root on 159 is 12.6095202129. Rounding to the nearest tenth should be 12.6.

Problems like this require a calculator for most people.

The approximate value of [tex]\sqrt{159}[/tex] to the nearest tenth is 12.61

Here,

We have to find the approximate value of [tex]\sqrt{159}[/tex] to the nearest tenth.

What is Rounding number?

Rounding is a method of approximating a number to its nearest place value.

Now,

The value of [tex]\sqrt{159}[/tex] = [tex]12.6095202129.[/tex]

To find Rounding number of 12.6095202129 nearest tenth look at the hundredth number. The number is 9 which is greater than 5, then add 1 in tenth place and remove all the number after tenth place.

Hence,

Rounding number of 12.6095202129 nearest tenth is 12.61

Step-by-step explanation:

I think these is your correct answer .

Answer:

if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash

so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap

the entire car needs 3/4 of a bottle of soap

Q) [35 - (8 + 2) × 3] = ?

→ 35 - {(8 + 2) × 3}

→ 35 - {10 × 3}

→ 35 - 30

→ 5 is the correct answer.

Hey there!

36 - 8 = 1 + 3

SOLVING FOR THE LEFT SIDE….

36 - 8

= 28

SOLVING FOR THE RIGHT SIDE….

1 + 3

= 3 + 1

= 4

So, this make your statement [false] because 28 ≠ 4 (Option B.)

The left side is bigger than the right side.

Good luck on your assignment and enjoy your day!

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

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).

Answer:

6×10-6 have greater value than 2×10-8

Step-by-step explanation:

6×10-6

60-6

=54

And

2×10-8

20-8

=12

Thus, 6×10-6 had the greatest value by 42 more than 2×10-8

6×10-6 have greater value than 2×10-8

The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Compare the numbers 6 x 10⁻⁶ and 2 x 10⁻⁸.

Then the numbers can be written as,

⇒ 6 x 10⁻⁶ and 2 x 10⁻⁸

⇒ 600 x 10⁻⁸ and 2 x 10⁻⁸

The number  600 x 10⁻⁸ times greater than the number 2 x 10⁻⁸ will be

⇒ 600 x 10⁻⁸ / 2 x 10⁻⁸

⇒ 300

The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.

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

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.
