Answer:
a. 3.5
Step-by-step explanation:
Since ∆ABG is similar to ∆CDG, therefore, their corresponding side lengths are proportional to each other.
Therefore:
DG/BG = GI/GH
10/5 = 7/GH (substitution)
Cross multiply
GH*10 = 7*5
GH*10 = 35
Divide both sides by 10
GH = 35/10
GH = 3.5

Answer:
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
Step-by-step explanation:
H0 : μ = 3.8
H1 : μ < 3.8
Test statistic :
(x - μ) ÷ s/sqrt(n)
(3.7 - 3.8) ÷ 0.6/sqrt(60)
Test statistic = - 1.29
The Pvalue from test statistic :
P(z < -1.29) = 0.0985
Reject Null if
Pvalue < α
0.0986 > 0.01 ; Hence, we fail to reject the null ;
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
60v = $15
60v/60 = $15/60
v = 0.25
The original value of the baseball card is $0.25
