Answer:
9 inches each side
Step-by-step explanation:
Answer:
D: As the x-values go to negative infinity, the function's values go to positive infinity.
Step-by-step explanation:
Since we are dealing with end behavior, we look at the graph infinitely:
When x-values go to negative infinity, we see that f(x) values go to positive infinity.
When x-values go to positive infinity, we see that f(x) values also go to positive infinity.
Therefore. our only correct answer is D.
Answer:
d
Step-by-step explanation:
Answer:
Null hypothesis is rejected. Standard deviation is > 8 miles per hour
Step-by-step explanation:
σ [Population standard deviation] = 8 , s [sample standard deviation] = s
n [no of items] = 8
H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8
χ2 = (n - 1) . s^2 / σ^2
= 49 x (10.5)^2 / 82 = 5402.25 / 64
χ2 = 84.410
df [degree of freedom] = n -1 = 50 - 1 = 49
P value (χ^2 49 > 84.410) = 0.00125
p = 0.0013
p < α ie 0.05
So, H0 is rejected
Hence we state that standard deviation is > 8 miles per hpur
I think it should be 25 since you are moving each point by 5 so yeah I hope you understand what I’m saying and best of wishes and really sorry if the answer was wrong but I tried my best!!
