Suppose MyBook sent out 2100 surveys. Which of these numbers of surveys being returned would prevent non response bias?

Jay organised a large wedding and 1/3 of them chose beef 5/12 of them chose Chicken and 69 of them chose vegetarian so how many

DerKrebs [107]

Answer:

276 Guests

Step-by-step explanation:

Calculation to determine how many guest were at the wedding

Guests that choose beef =1/3

Guests that choose chicken= 5/12

Guests that choose vegetarian=69

Now let calculate the how many guest were at the wedding

Let x represent the numbers of guest that were present at the wedding

Hence,

x/3 + 5x/12 + 69 = x

9x/12 + 69 = x

12x/12 - 9x/12 = 69

3x/12 = 69

x/4 = 69

x=69*4

x = 276 guests

Therefore the numbers of guests that were at the wedding is 276

Julia works for a company selling light bulbs. She sells fluorescent light bulbs for $5 a piece and incandescent light bulbs for

stellarik [79]

The solution to the amount of light bulbs Julia needs to sell to meet her quota is represented by the shaded area in graph X.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the incandescent light bulbs and y represent the fluorescent light bulbs. Therefore:

x + y > 100 (1)

Also:

2x + 5y ≥ 350 (2)

The solution to the amount of light bulbs Julia needs to sell to meet her quota is represented by the shaded area in graph X.

-1.84 - 2.3m= -2.3(m+.8)

alexira [117]

Answer:

m ∈ R

Step-by-step explanation:

- 1,84 - 2,3m = - 2,3(m + 0,8)

- 1,84 - 2,3m = - 2,3m - 1,84

m ∈ R

Which number would make the sentence true?

AURORKA [14]

Answer:

22% = 0.22

Step-by-step explanation:

Lat'e express all the given numbers in decimal form so we understand how they are located on the number line.

We start with 2/11 , since the number we are looking for has to be larger than this \, and smaller than 1.42:

$\frac{2}{11} = 0.181818181818...$

So we understand that we are looking for a number that can be placed between the lower boundary (0.181818...) and the upper boundary (1.42) on the number line. That is: we are looking for a number greater than 0.18181818... and less than 1.42.

Now let's look at each of the given options (also writing them in decimal form to facilitate the comparison with the lower and upper boundaries we just found):

$1\frac{2}{3} = 1.66666666...$ This number is grater than the upper boundary given to us (1.42), it would be placed to the right of 1.42 on the number line. Therefore we discard it for not being in the requested interval (section) of the number line.

0.153 is already in decimal form, and clearly less than (thus to be placed on the left of) the lower boundary (0.181818...) of the requested interval. Therefore we discard it for not being in the requested interval (section) of the number line.

22% in decimal form is written as: $\frac{22}{100} = 0.22$ . This number is greater than the lower boundary (0.181818...) and also less than the upper boundary (1.42). Therefore it is a choice that would make the sentence true.
