What is - 1 2/3 divided by 5/6

1 answer:

5 0

For this question you should know -1 2/3 is equal to -1/3 so now you can say:
-1/3 ÷ 5/6 which is equal to -1/3 * 6/5 = -2/5 :)))
i hope this is helpful
have a nice day

Catherine Chao, Director of Marketing Research, needs a sample of households to participate in the testing of a new toothpaste p

Answer:

Convenience sampling.

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. Quota sampling.

6. Convenience (opportunity) sampling.

Convenience sample can be defined as a sampling technique in which the representatives to be used are easily accessible. For example, a researcher using a social media poll such as Twitter polls.

In this scenario, Catherine Chao, Director of Marketing Research, chooses thirty-six of her closest friends to participate in the testing of a new toothpaste package. Thus, Catherine's sample is a convenience sampling.

Solve using the guess-and-test strategy. Michael and Susan have a combined age of 17 years. Michael is 5 years older than Susan.

nadezda [96]

If you take 17 and minus 5 you get 12 so if you add 5 back it makes 17 and since Michael is 5 years older he is 22, my mistake

1. Find the length of a rectangular lot with a perimeter of 124 feet if the length is two more than twice the width.

sp2606 [1]

ANSWER TO QUESTION 1

Let the width be
$w$
units.

Twice the width will be

$2w$

Two more than twice the width will be

$2w + 2$

We were told that the length is 2 more than twice the width. This means that,

$l = 2w + 2$

This implies that,

$w = \frac{l - 2}{2} - - eqn(1)$

The formula for finding the perimeter of a rectangle is given by:

$perimeter = 2w + 2l - - eqn(2)$

We substitute 124 for the perimeter and equation (1) into equation (2)

$124 = 2( \frac{l - 2}{2} ) + 2l$

This implies that,

$124 = l - 2 + 2l$

$\Rightarrow 124 + 2 = l + 2l$

$\Rightarrow 126 = 3l$

We divide both sides by 3 to obtain,

$l = 42$

Therefore the length is 42 feet.

ANSWER TO QUESTION 2

Let the width be
$w$

units.

Five more than the width will be

$w + 5$

We were told that the length is 5 more than the width. This means that,

$l = w + 5$

We make w the subject to obtain,

$w = l - 5 - - eqn(1)$

The perimeter is given by,

$perimeter = 2w + 2l - - eqn(2)$

We substitute 50 for the perimeter and equation (1) into equation (2)

$50 = 2(l - 5) + 2l$

Dividing through by 2 gives,

$25 = l - 5 + l$

$\Rightarrow 25 + 5 = l + l$

$\Rightarrow 30 = 2l$

We divide both sides by 2 to get,

$l = 15$

Therefore the length is 15 feet.
