Answer:
Dimensions = 21 centimeters by 4.2 centimeters.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 50cm
Translating the word problem into an algebraic expression, we have;
L = 5W
To find the dimensions of the rectangle;
Perimeter of rectangle = 2L + 2W
50 = 2L + 2W
50 = 2(5W) + 2W
50 = 10W + 2W
50 = 12W
W = 50/12
W = 4.2 cm.
To find the length;
L = 5W
L = 5*4.2
L = 21 cm.
The answer is: [C]: " 3.200 * 10⁷ h " .

Explanation:
________________________________
19.2 * 10⁸ min * (1 hr / 60 min) ;
= (19.2 * 10⁸)
_______________ ;
60
_____________________________
Divide EACH SIDE of the fraction by "10" ; to get:
___________
(19.2 * 10⁷)
_______________ ;
6
<span>______________________________
</span>⇒ (19.2) ÷ (6) = 3.2 ; so rewrite as:

3.2 * 10⁷ ; which corresponds with:
Answer choice: [C]: " 3.200 * 10⁷ h " .

Answer:
The Correct option is - d. all of the above.
Step-by-step explanation:
To find - In assessing the validity of any test of hypotheses, it is good practice to
a. examine the probability model that serves as a basis for the test by using exploratory data analysis on the data.
b. determine exactly how the study was conducted.
c. determine what assumptions the researchers made.
d. all of the above.
Proof -
All the Given options are correct to study the validity of a hypothesis test.
So,
The Correct option is - d. all of the above.
Answer:
218
Step-by-step explanation:
this is ratio.
5+4=9. which is the ratio you add it.
5/9×360=200
therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.
therefore the number of boys in school from january to february is 218.
