You can do 20/2=10 This helps because it is just doing the reverse so you know if you get it both ways that it is correct. Medal please?

Always try to use the inverse operation. Inverse operation is the opposite of your current operation. So if that problem is '2 x 10 = 20' Then you're going to use ' 20 (Divided by) 10' If it equals the first number, which is two, than your answer is correct. hope this helped :)

Answer:

See below ~

Step-by-step explanation:

<u>(a) Mean of the data</u>

  • 2.4 + 1.6 + 3.2 + 0.3 + 1.5 / 5
  • 9/5
  • <u>1.8</u>

<u></u>

<u>(b) New mean after each data point increased by 10</u>

  • 12.4 + 11.6 + 13.2 + 10.3 + 11.5 / 5
  • 59/5
  • <u>11.8</u>

<u></u>

<u>(c) New mean after each data point doubled [from (b)]</u>

  • 24.8 + 23.2 + 26.4 + 20.6 + 23 / 5
  • 118/5
  • <u>23.6</u>

Russ is solving an equation where both sides are linear expressions. he sets the expressions equal to y and graphs the system fi
Dafna1 [17]

The correct  option (D).

There are infinitely many intersection points.

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

a two-variable equation that, when plotted on a graph, results in a straight line.

<h3>What does intersection point mean?</h3>

The term "point of intersection" refers to the intersection of two lines.

<h3>According to the given information:</h3>

Russ is attempting to solve an equation whose two sides are both linear expressions.

He graphs the system and finds that they are on the same line after setting the expressions to y.

Since both lines are the same, there are an endless number of junction places.

Russ should therefore consider the outcome to be option (D) There are a limitless number of intersections.

I understand that the question you are looking for is:

Russ is solving an equation where both sides are linear expressions. He sets the expressions equal to y and graphs the system finding that they are the same line. How should Russ interpret this outcome? There are no intersection points. There is exactly one intersection point. There are exactly two intersection points. There are infinitely many intersection points.Russ is solving an equation where both sides are linear expressions.

A. There are no intersection points.

B. There is exactly one intersection point.

C. There are exactly two intersection points.

D. There are infinitely many intersection points

WARRIOR [948]

Answer:

This is an observational study based on a stratified sample.

Step-by-step explanation:

This study aimed to check which clean-up/drying up method after handwashing was more effective; that is, do dryers eliminate more germs than paper towels.

It involved 100 people that took part in the study. The 100 of them contaminated their hands and were instructed to wash their hands with soap and water for 15 seconds before the participants are randomly grouped into two strata; one stratum/group (consisting of 50 participants) that dries their hands with a dryer and another (also consisting of 50 participants) that dry their hands with paper towels.

An observational study is one in which data is collected only by monitoring the events of the study. The conductor of the study in no way tries to intervene or control any of the variables being studied. No control, no tweaking of factors, just observe and record data.

An observational study based on a stratified sample is an observational study that uses the stratified sampling method to carry out its objectives. It randomly puts each of the participants being observed into groups or strata. Each group of randomly assigned participants are then required to run the test for one of the variables being compared.

This is exactly what the study in the question describes. This is why this study is undoubtedly an observational study based on a stratified sample.

Hope this Helps!!!
