A survey of 50 randomly selected students showed that 38 students buy lunch at school and 12 students bring lunch from home each day. Name the sampling Technique AND if that method is biased or unbiased.

Answers

Answer:

We know that our sample is a group of 50 randomly selected students.

First, we want to know the name of the sampling technique.

There are a lot of sampling techniques, but knowing that the students are selected randomly, we can conclude that this is the simple random sampling technique, where each individual is chosen entirely by chance (so all the students have the same probability of being chosen)

Now we want to know if the method is biased or not,

Always that we use the simple random sampling technique, we will have an unbiased sample.

PLEASEEEE HELP ME IM TAKING A TEST
You are trying to find the area of a deck that is surrounding a rectangular pool. The length of the deck is 2x + 1 and the width is 5x + 2. The pool is a square with sides of 2x. Write the Polynomial that represents the area of ONLY the deck.

Answers

For deck,
Length = 2x + 1
Width = 5x + 2

For pool,
Length = 2x

Area of deck including pool = (2x + 1)(5x + 2) = 10x^2 + 4x + 5x + 2 = 10x^2 + 9x + 2

Area of pool = 2x * 2x = 4x^2

Area of only the deck = 10x^2 + 9x + 2 - 4x^2

= 6x^2 + 9x + 2

Step-by-step explanation:

which can be simplified

highest common factor is 5

therefore divide both numbers by 5

5/8

Figuring out ratios is pretty simple. Example: If the ratio of soccer balls to baseballs is 3:1 that means there are 3 soccer balls for every 1 baseball. Notice how it says “soccer balls to baseballs” and “3:1” the first type of ball/object is the subject for the 3 and the second ball/object is the number for the 1. So when it asks the ratio of chocolate cookies to the whole box, you need to put the number of chocolate cookies first (25) and the cookies in the whole box (40). So now the ratio is 25:40. Simplify and make it into fraction form and the answer is 5/8.

Answers

Answer: Correct answer is C -I just took the test

we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.

you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)

now we have:

g(x) = -f(x) = - 4(1/2)x

then the right answer is the third option:

g(x) = -4(1/2)x

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as
whole numbers or as improper fractions in simplest form.

Answers

Given:

The equation is

[tex]-x+y=8[/tex]

To find:

The x- and y-intercepts.

Solution:

We have,

[tex]-x+y=8[/tex]

Put x=0 in the given equation to find the y-intercept.

[tex]-(0)+y=8[/tex]

[tex]y=8[/tex]

Put y=0 in the given equation to find the x-intercept.

[tex]-x+(0)=8[/tex]

[tex]-x=8[/tex]

[tex]x=-8[/tex]

Therefore, the x-intercept is -8 and the y-intercept is 8.

Janie has 2 3/4 yards or yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks

Answers

Answer:

1 3/8 yards

Step-by-step explanation:

Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks

The above question is calculated as:

2 3/4 yards × 1/2 of ribbon

= 2 3/4 × 1/2

= 11/4 × 1/2

= 11/8

= 1 3/8 yards

Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks
