In​ randomized, double-blind clinical trials of a new​ vaccine, rats were randomly divided into two groups. Subjects in group 1

received the new vaccine while subjects in group 2 received a control vaccine. After the second​ dose, 104 of 669 subjects in the experimental group​ (group 1) experienced drowsiness as a side effect. After the second​ dose, 61 of 550 of the subjects in the control group​ (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the α=0.10 level of​ significance?

A map of a park says its scale is 1 to 100. What does that mean?
Alex777 [14]

A scale is a term that refers to the <em>representative fraction</em> for comparing the <u>original</u> length and <u>image</u> length of a given <u>object</u>. It means implies that every 1 unit on the <u>drawing</u> is equal to <u>100</u> units on the <u>park</u>.

A <em>scale</em> is a term that can be referred to as the <em>representative fraction</em> that compares the <u>original</u> length and <u>image</u> length of a given <em>object</em>. Types of <u>scale</u> include enlarged scale, reduced scale, and real scale.

  • Enlarged scale is a <u>scale</u> that is used when the <u>size</u> of a given <em>object</em> is to be <em>increased</em>.
  • <em>Reduced scale</em> is used when the <u>size</u> of a given <u>object</u> is to be <em>decreased</em>.
  • <u>Real scale</u> implies the <em>exact size</em> of a given <u>object</u>.

<u>Scale</u> can be expressed as;

Scale = \frac{length on drawing}{original length}

Thus a <em>scale</em> has no unit.

Therefore, the given question <em>implies</em> that every 1 unit on the <u>drawing</u> is equal to 100 units on the <u>original</u> park. Thus it is a <em>reduced scale</em>.

Find the solution of this system of equations. <br> -2x-6y=-16<br> 4x-6y=-58
Yanka [14]
-(-2x-6y=-16)

2x+6y=16
4x-6y=-58

Y's cancel out, then add the rest

6x=-42

divide both sides by six

x=-7

plug x into any previous equation

2(-7)+6y=16

-14+6y=16

6y=30

y=5

1. If you bought a book for $12 and a CD for $9 how much money would you get back if you gave the clerk $40?
Alex

I would get $19 back if I gave the clerk $40

An equation is an expression used to show the relationship between two or more variables and numbers.

Total money spent on book and CD = $12 + $9 = $21

The money gotten back = $40 - $21 = $19

I would get $19 back if I gave the clerk $40
