Answer:

A square root of a number 'x' is a number y such that y2 = x, in other words, a number y whose square is y. For example, 3 is the square root of 9 because 32 = 3•3 = 9, -3 is square root of 9 because (-3)2 = (-3)•(-3) = 9. When writing math, people often use sqrt(x) to mean the square root of x

Step-by-step explanation:

The square root of 9.6 is 3.0983866769659336

Or, √9.6 = 3.0983866769659336

Indicate whether the study is an observational study or a controlled experiment. A group of boys is randomly divided into two gr

MariettaO [177]

Answer:

Controlled Experiment

Step-by-step explanation:

The controlled experiment involves the experiment in which all factors are considered as constants whereas one factor is not fixed and that one is independent variable whose effect is to be tested. In short, in controlled experiment one group of data contains control group and one or more other groups are examined by considering all other factors constant except for one factor. The control group is the group that doesn't receive any treatment whereas treatment is applied to experimental group and then effect of treatment is measured through comparing both groups.

Here group of boys is divided in to two groups

The group watched violent cartoon= Experimental group

The group watched cartoons without violence= Control group

The researchers want to know whether the violent actions of boys are linked to violent cartoon and for this purpose these boys are divided into experimental group and control group and after 1 hour of cartoons watching the researcher will observed boys for next two hours.

Hence the study is Controlled experiment.

The vector ~v represents the displacement vector from Portland, Oregon to Houston, Texas. The vector w~ represents the displacem

Art [367]

Answer:

the displacement of the plane is $- \= w$

The displacement of plane from Portland to Akron with layover at Houston is

$\= v + \= w$

the vector which defines this displacement is $\= v + \= w =- 2500 \ km$

Step-by-step explanation:

From the question we are the

The displacement from Portland, Oregon to Houston, Texas. is $\= v$

The displacement from Houston, Texas to Akron, Ohio. is $\= w$ a

The motion of the plane in question a is in the opposite direction to vector $\= w$

So the displacement of the plane is $- \= w$

The motion of Portland to Houston to Akron is in the direction of both vector $\= v$ and $\= w$ so

The displacement of plane from Portland to Akron with layover at Houston is

$d = \= v + \= w$

From the question we are told that the plane flies over Portland to get to Anchorage, Alaska which implies that it is moving in opposite direction to the vector $\= v$

Give that distance from Portland to Houston is $\= v = 3000 km$

and the distance from Portland to Anchorage is $\= w = - 5500$ km

Then the vector which defines this displacement is mathematically represented as

$\= v + \= w = 3000 -5500$

$\= v + \= w =- 2500 \ km$

Find the two angles and show work!!!

USPshnik [31]

Answer:

x=23.5

Step-by-step explanation:

90=25-x/2+18

combine like terms

90=43-x/2

subtract 43 from both sides

47= -×/2

47/2= 23.5

x=23.5

90-25= 65

65-18=47

47/2=23.5

Why are box and whisker plots called box and whisker plots? links, paragraphs please.

alina1380 [7]

Answer:

there is a box in the middle and lines( which can be called whiskers) on the side

Step-by-step explanation:

lower quartile, upper quartile, and median make the box. Least and greates value make the whiskers

Wikipedia:

In addition to the box on a box plot, there can be lines (which are called whiskers) extending from the box indicating variability outside the upper and lower quartiles, thus, the plot is also termed as the box-and-whisker plot and the box-and-whisker diagram.
