Answer:
32
Step-by-step explanation:
Daisy's mom is 4 times as old as she.
m = 4d
The sum of their ages 6 years ago was 28.
(m - 6) + (d - 6) = 28
Substitute for m = 4d
(4d - 6) + (d - 6) = 28
Combine like terms
5d - 12 = 28
5d = 40
Divide by 5
d = 8
m = 4d
m = 4 * 8
m = 32
Answer:
<em> All college freshman </em>is called <em>Population and Right handed students are excluded is called sample from Population</em>
Step-by-step explanation:
<u>Explanation</u>:-
<em>Population:</em>- The total of the observations which we are concerned
given data <em>all college freshman </em>is called <em>Population</em>
<u><em>Sample</em></u><em> :-</em>
<em>A sample is a subset of a Population</em>
<em>Given data all college freshman </em>is called <em>Population and Right handed students are excluded is called sample from Population</em>
3 x 4 = 12
12/12 - 1/3 ( so 4/12) = 8/12
8/12 - 1/4 ( so 2/12 as you only have 8/12 left) = 6/12
Answer = 6/12 = 1/2 or 50%

Rules for using scientific notation:
1.- The number before the decimal point must be between 1 and 10.
2.- Determine the exponent
3.- It must be in decimal format, ( x 10)
A 3.8*10^12 This number is in correct scientific notation.
B 33.8* 10 This number is incorrect, because before the decimal point the number must be between 1 and 10.
C 3.8 *20^8 This number is incorrect because the power must be 10 not 20.
