Answer:

if 100 came by in 2 hours 50 would come by in one hour

Step-by-step explanation:

split it it's by 2

If 100 came by in 2 hours then 50 would come by in one hour.

There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.

We have been given 100 cars pass by in 2 hours​

We need to find the unit rate.

Total car = 100

Time = 2 hours

Unit rate = 100/2

Unit rate = 50

Therefore, the unit rate of 50 car in one hour.

Answer:

D. x=1

Step-by-step explanation:

Solve  :    x-1 = 0

Add  1  to both sides of the equation :

                     x = 1

x = 1 for equation 5x - ( 4x - 1) = 2.

An equation is a mathematical statement that shows that two mathematical expressions are equal. It may have one variable, two, three and so on.

For given equation,

5x - ( 4x - 1) = 2

This is a equation in one variable which can be solved by transposing the terms.

Firstly, Solving the parenthesis,

5x-4x+1=2

Then, Solving the like terms.

x+1=2

To calculate the value of x, subtract 1 from both the sides.

x+1-1=2-1

x=1

Thus, the value of x is 1. So, option d) is correct.

Answer:

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

There are various types of sampling used by researchers and these are;

1. Random sampling.

2. Systematic sampling.

3. Stratified sampling.

4. Cluster sampling.

5. Opportunity or convenience sampling.

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.

For example, John a psychologist standing on the street requesting that passersby join in his research study.

Answer:

Adele is not correct.

Step-by-step explanation:

The statement in itself wields an incorrect answer. However, when she states "sixty-two hundredths" it is further proven incorrect. This is because the 0.062 part of the total 0.462 would be pronounced as 62 thousandths.

Therefore, Adele is incorrect. The correct answer, however, would be: "Zero and four-hundred sixty-two thousandths."

Answer:

Step-by-step explanation:

volume = πr²h = π·3²h = 63π

h = 7 cm

The height of the given cylinder is 7 cm. Therefore, option D is the correct answer.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, the volume of a cylinder is 63π cm³ and the radius is 3 cm.

We know that, the formula to find the volume of a cylinder is πr²h.

Now, πr²h=63π

π×3²×h=63π

h= 7 cm

Therefore, option D is the correct answer.

Answer:

The gradient of the line segment between the points (1,-1) and (3,-13) is -6

Step-by-step explanation:

The gradient of the line segment between the points (1,-1) and (3,-13) is -6

Step-by-step explanation:

We need to find the gradient of the line segment between the points (1,-1) and (3,-13)

The gradient is basically the slope of line.

The formula used to calculate slope\gradient is: Slope=\frac{y_2-y_1}{x_2-x_1}\\

We have x_1=1, y_1=-1, x_2=3, y_2=-13

Putting values and finding slope

Slope=\frac{y_2-y_1}{x_2-x_1}\\\\Slope=\frac{-13-(-1)}{3-1} \\Slope=\frac{-13+1}{2} \\Slope=\frac{-12}{2}\\Slope=-6

So, gradient of the line segment between the points (1,-1) and (3,-13) is -6
