BRAINLIEST INCLUDED!!!

Identify the following data set: ... a survey from Gwinnett County Public Schools, required that all of the teachers fill out th

kozerog [31]

The following data set is A population ⇒ answer A

Step-by-step explanation:

Lets revise the definition of each choice

1. A population, is a discrete group of people, animals or things that

can be identified by at least one common characteristic for the

purposes of data collection

2. A sample is just a part of a population

3. The parameter is a fixed measure which describes the target population

Parameter is a fixed and unknown numerical value

4. A statistic is a characteristic of a small part of the population

The statistic is a variable and known number which depend on the

sample of the population

∵ All of the teachers in Gwinnett County Public Schools fill out the

survey

∴ The data set is population

The following data set is A population

Which graph is an example of a function whose parent graph is of the form y = √x?

Maksim231197 [3]

Answer:

The correct option is 1.

Step-by-step explanation:

The given parent function is

$y=\sqrt{x}$

1. Domain of the function is all positive real number including 0.

2. Range of the function is all positive real number including 0.

3. It is an increasing function. It increases at decreasing rate.

First graph increase at decreasing rate and it starts from (-4,-1), therefore the required function is

$y=\sqrt{x+4}-1$

Therefore graph 1 is an example of a function whose parent graph is of the form y = √x.

Second graph is a parabola, so it is the graph of a quadratic function.

Third graph is a rectangular hyperbola, so it is the graph of a rational functions.

Fourth graph is increasing at increasing rate, so it is the graph of an exponential function.

Therefore options 2, 3 and 4 are incorrect.

Find the slope to Y = 5/2x-3

son4ous [18]

Answer:

slope = 5/2

Step-by-step explanation:

A candle maker adds lemon oil to wax to make the lemon-scented candle shown. How many ounces of oil will he need for the candle

liraira [26]

Answer:

The ounces of oil needed is 5 ounces of oil

Step-by-step explanation:

The first thing to do here is to calculate the volume of the lemon-scented candle given.

Looking at shape the volume can be calculated using the formula L * B * H

where L(length) = 10cm , B(breadth) = 8cm and Height(h) = 25cm

The volume V is thus = 10 * 8 * 25 = 2,000 cm^3

The ounces of oil needed for the candle to have 0.0025 ounces of oil per cm^3 of wax will be = The volume of the lemon-scented candle * 0.0025 ounces of oil per cm^3 of wax

That will be = 0.0025 * 2,000 = 5 ounces

A bag has 4 red 3 white 2 blue and 1 green marble in it. Use this information to answer question 9-11.

love history [14]

#'s 9-14

Base info: 40% are red, 30% are white, 20% are blue, and 10% are green

9) 40% chance to get red, 10% chance to get green. 50% chance to get one of either.

10) getting red: 40%

Getting blue: 20%

11) 80% (100% - 20% = 80%)

1/8 = 12.5%

12) 12.5% chance

13) 25% chance

14) 12.5 x 5 = 62.5

62.5% chance
