SAT scores are adjusted so that the mean score is about 500 and the standard deviation is about 100. Draw the bell curve and fill in the numbers across the bottom.
<h2>
The total number of observations in the frequency distribution = 20</h2>
Step-by-step explanation:
The given table from the given data:
Class: 12 - 15 15 - 18 18 - 21 21 - 24 24 - 27
Frequency: 3 6 3 4 4
To find, the total number of observations in the frequency distribution is __________ .
Class: 12 - 15 15 - 18 18 - 21 21 - 24 24 - 27
Frequency: 3 6 3 4 4
Cumuative
frequency (CF): 3 9 12 16 16
The total number of observations in the frequency distribution = 20
Answers:
<h2>use x = 0 for y-intercept</h2><h2>use y = 0 for x-intercept</h2>
Step-by-step explanation:
There is not really a way to explain, that is just the formula, memorize it.
<h3>Finding the y-intercept</h3>
3x = 2y + 8
find y-intercept
x is 0
2y + 8 = 0
2y = -8
Y-INTERCEPT y = -4
<h3>
Finding the x-intercept</h3>
3x = 2y + 8
3x = 8
X- INTERCEPT x = 2 2/3

number = 51
let the number be n then one third is and decreased by 6 gives
- 6 = 11 ( multiply all terms by 3 )
n - 18 = 33 ( add 18 to both sides )
n = 33 + 18 = 51
