-5>2-3

-5>-1

-1 is not greater than -5

So false

For

C. (2,3)

3>2-3

3>-1

3 is greater than -1

So True

For

D. (2,-2)

-2>2-3

Answers

Answer: See explanation

Step-by-step explanation:

Cluster sampling, is a form of sampling whereby the population is divided by the researchers into smaller groups that are referred to as clusters and then the sample will be taken from the clusters formed.

Convenience sampling is when a sample is drawn based on the available population.

Systematic sampling is when a sample is gotten when the members are taken at regular intervals e.g 5th person, 12th items etc.

Simple random sampling is when the sample is selected from the larger population and in this case, every member involved can be selected as they all have an equal chance.

Based in the definition above, the answers will be:

a. Cluster sample

b. Convenience sample

c. Systematic sample

d. Simple random sample

What is the image of (-10,-6) after dilation by a scale factor of 1/2 ​centered at the origin?

Answers

The coordinate of resulting image after dilation is (-5, -3)

Dilation and scale factors

Given the coordinate of an image (-10,-6), dilating the coordinate by 1/2 means reducing the image by multiplying each coordinate by the factor of 1/2.

Image = (1/2(-10), 1/2(-6))

Image = (-5, -3)

From the calculation above, you can see that the coordinate of resulting image after dilation is (-5, -3)

Answers

Answer:

Step-by-step explanation:

poop kdfkdkddkejdfjdidjs didneidndzusnxixdn

1 1/2 hours

Time spent by Antonio in driving = 3 1/4 = 13/4

Time spent in gardening = 1 3/4 = 7/4

In order to find how much he spend driving than gardening, we can subtract 13/4 and 7/4.

13/4 - 7/4

Te denominator is same. So, we can directly subtract the numerators.

13-7/4

=6/4

= 3/2 = 1 1/2

Therefore, Antonio spent 1 1/2 hours more in driving than gardening.

The system of equations y =−7x + 8  and y = −7x − 8 ​ have no solution

How many solutions does the system have?

From the question, we have the following parameters that can be used in our computation:

y =−7x + 8

y = −7x − 8 ​

Subtracting the two equations

We have

y - y = -7x + 7x + 8 + 8

When the like terms are evaluated, we have

The above equation is false

This means that the equation has no solution

When x = 0, y = 6.  So, [tex]6 = kb^{0}[/tex] = k(1 ) = k

Since k = 6 we have [tex]y = 6b^{x}[/tex]

When x = 1, y = 12.
