Answer:
its 17degree as it is supplement to 163
Z = (X - mean)/sd
-1 = (28 - mean)/sd
mean - sd = 28 . . . (1)
-0.5 = (34 - mean)/sd
mean - 0.5sd = 34 . . . (2)
(1) - (2) => -0.5sd = -6
sd = -6/-0.5 = 12
From (1), mean = sd + 28 = 12 + 28 = 40
mean = 40
standard deviation = 12
1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.
Step-by-step explanation:
Given,
Total cost for session = $43.25
Entrance fee = $7
Charges per minute = $1.25
Let,
t be the number of minutes raymond was on Trampoline
Total cost for session = entrance fee + Charges per minute * No. of minutes

1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.
