Answer:
3 + 3 + 1
Step-by-step explanation:
The doubles is 3+3 which is 6 plus 1 is 7
Answer:
H0 : σ²= 7.2²
H1 : σ² < 7.2
We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
Step-by-step explanation:
H0 : σ²= 7.2²
H1 : σ² < 7.2²
The test statistic :
X² = [(n - 1)*s² ÷ σ²]
s² = 3.5
n = sample size = 25. ; s²
X² = [(25 -1)*3.5² ÷ 7.2²
X² = (24 * 3.5^2) / 7.2^2
X² = 5.67
Pvalue from Chisquare statistic :
P(X² < 5.67) = 0.000042
Pvalue < α ; we reject the Null.
Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
X=-4 x=0 x=5
5-4-12=-4-7 5+0-12=0-7 5+5-12=5-7
-11=-11 -7=-7 -2=-2
Answer:
It's linear!
Step-by-step explanation:
Just rewrite the equation as
y = x + 3
It has a slope and y-intercept, the most crucial parts that satisfy a linear equation. Since the slope is constant, it has to be linear.
tadah!
