Answer:
it is a quadratic equation
Step-by-step explanation:
3x(3x+7) +2(3x+7)
9x square +21x +6x+14
= 9x square +27x +14
Answer:
H0 : μ = 8.5
H1 : μ > 8.5
1 sample t test ;
Test statistic = 2.53
Pvalue = 0.994
No, we fail to reject the Null ;
There is no significant evidence to support the Claim that the mean running time of light bulb is greater Tha last year.
Step-by-step explanation:
H0 : μ = 8.5
H1 : μ > 8.5
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(8.7 - 8.5) ÷ (0.5 / sqrt40)
Test statistic = 2.53
The Pvalue :
P(Z < 2.53) = 0.9943
Pvalue = 0.994
Decison region :
Reject H0 ; if Pvalue < α
0.9943 > 0.05 ; We fail to reject the Null

9 4 1 0 1 4 9
Answer:
Sample answer: The median of the means for Grade 8 is greater than for Grade 12. However, there is less variation in the data for Grade 12 since the length of the box for Grade 12 is shorter than the one for Grade 8.
