Answers

Answer:

Step-by-step explanation:

Let the number = x

8x - 13 = 4x + 3              Add 13

8x = 4x + 3 + 13             Combine

8x = 4x + 16                   Subtract 4x

8x - 4x = 16                    Combine

4x = 16                           Divide by 4

x = 16/4

x = 4

-3a+2b=-3
solve for a

Answers

-3a=-3-2b
a=1+2/3b

Solution
a=1+2/3b

Answer:

a = (3 + 2b) / 3

Step-by-step explanation:

1) Move 2b to the right.

-3a + 2b = -3

-3a = -3 - 2b

2) Leave only a on the left.

a = (-3 - 2b) / (-3)

a = -(3 + 2b) / (-3)

a = (3 + 2b) / 3

03.01 MC) A surveyor randomly interviewed 65,439 people who live in Virginia to gather information on whether national healthcare is accomplishing its goals. Part A: What are the population and sample in this survey? (4 points) Part B: The survey found that 71% of females and 88% of males visited a family doctor at least once in the past year. Do you think these approximations of the sample are close to approximations of the entire population? Explain. (6 points)

Answers

Answer:

Part A: The population and the sample of the survey are;

The population = The entire population of the country

The sample = 65,439 people in the state of Virginia

Part B: Given that the survey was based on only one state and only one model of health care delivery, the approximations of the sample will not be close to the approximations of the entire population

Step-by-step explanation:

The given information are;

The number of people interviewed in the survey = 65,439 people

The location of the people surveyed = Virginia

The goal of the survey = The effectiveness of the national healthcare

The number of females that visited a family doctor at least once in the past year = 71%

The number of males that visited a family doctor at least once in the past year = 88%

Part A: The population and the sample of the survey are;

The population = The entire population of the country

The sample = 65,439 people in the state of Virginia

Part B: Given that the survey was based on only one state and only one model of health care delivery, the approximations of the sample will not be close to the approximations of the entire population.

Answer:

y + 1 = [tex]\frac{3}{4}[/tex](x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (5, 2)

m = [tex]\frac{2+1}{5-1}[/tex] = [tex]\frac{3}{4}[/tex]

using (a, b) = (1, - 1 ), then

y - (- 1) = [tex]\frac{3}{4}[/tex](x - 1) , that is

y + 1 = [tex]\frac{3}{4}[/tex](x - 1)

add 28 to both sides (-8+28=20)

11x=7x+20

subtract 7x from both sides (11x-7x=4x)

4x=20

divide both sides by 4 to isolate x (20/4=5)

Step-by-step explanation: I just did a quiz with the same question

The factor of the given expression are (5x + 2)(5x+2)

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We will recognize that the first (25x^2) and last (4) terms are perfect squares. The middle term is double the product of the roots of those squares is;

 2(5x)(2) = 20x

Which means the given expression is a perfect square trinomial, and that it is the square of (5x+2).

 25x^2 +20x +4

= (5x +2)^2

= (5x +2)(5x +2)

Here, we have a=5x, b=2.

The length of a rectangle is 5 less than twice it's width. The perimeter is 26 meters. Find the deminsion of rectangle.PLease show me step by step

Answers

Answer:

Width = 6 m and lenght = 7 m

Step-by-step explanation:

Let x be the width of the rectangle.

lenght = 2x - 5

Perimeter means the addition of all sides of the rectangle.

Thus, x + x + 2x - 5 + 2x - 5 = 26

2x + 2x + 2x = 26 + 10

6x = 36, x= 6

Therefore, width is 6 m and lenght is 2 (6) -5 == 7 m
