Answer:
The prime factorization of the number 24 is 2 × 2 × 2 × 3.
Answer:
False
Step-by-step explanation:
Given that a high school reports that its students' SAT scores were down by 12% in one year. The next year, however, the test scores rose by 20%.
Let score initially be 100
Down by 12
Next year score 88
For succeedingyear
increase is 20% =
Score in the 2nd year = 
Hence overall scores improvement is 5.6% and not 8%
Answer:
It's 65.97
Step-by-step explanation:
Answer:
Step-by-step explanation:
n = sample size = 5
a) Let us determine the sum





Now we can determine 




The estimate b of the slope β is the ratio of
and 


The mean is the sum of all value divide by number of values


The estimate a of the intercept is


General least square equation;

replace alpha by a = 3 and beta by b = 0.67 in general least equation
y = a + bx
195.9 + 0.67x
b)
<em>Scatter plot is shown in the attached file</em>
x is on the horizontal axis
y is n the vertical axis
The degree of freedom of regression is 1
because we use one variable s predictor variable

The degree of freedom of error is the sample size n decrease by 2

Total df is equal to the sum of seperate degree of freedom dfR and dfE
total df = 1 +3 4

Total SS =Syy= 45007.2
SSE + Total SS = SSR
= 45007.2 - 43146.9296
= 1860.2705
