Y = 7x + 12.....x = number of tickets and y = total cost
and there are 4 tickets ordered (Frank and 3 friends)...so x = 4
y = 7(4) + 12
y = 28 + 12
y = 40 <=== so he paid 40 bucks for them
Answer:
V=785.4
Step-by-step explanation:
V=pi*r^2*h
V=pi*5^2*10
V=pi*25*10
V=pi250
V=785.39=785.4
Answer:
0.913716
Step-by-step explanation:
Given a normal distribution :
Mean, x = 1050
Standard deviation, σ = 375
The Zscore = (x - mean) / σ
Zscore = (675 - 1050) / 275
Zscore = - 1.364
The probability :
P(Z > - 1.364)
P(Z > - 1.364) = 1 - P(Z < - 1.364) = 1 - 0.086284
P(Z > - 1.364) = 0.913716
D. 25% as there are 8 sections and two wanted outcomes this can be simplified into a 1/4 so 1/4=25%
It can be expressed by 4(3)+4(9) you take the digit outside of the bracket and multiple by each individual digit inside the bracket.
