Answer:
Option 2: 1.5 is the correct answer.
Step-by-step explanation:
Given information is:
Mean = μ = $27
SD = σ = $5.50
A z-score simply tells us how far a selected data value from the mean is.
Z-score is denoted by z and is given by the formula:
Let x = $35.25
Putting the values of mean and SD we get,
The value of z-score for a price of $35.25 per barrel is 1.5
Hence,
Option 2: 1.5 is the correct answer.
Answer:
10
Step-by-step explanation:
height = 2(Base) + 4
h = 2b + 4
Area of Triangle
A= bh/2
15 = b (2b) +4) / 2 multiply both sides by 2 and distribute the b
30 = 2 + 4b Divide everything by 2
15 = + 2b Subtract 15 from both sides
+ 2b -15 = 0 Look a quadratic. Factor or use quadratic formula
b = 3 or b = -5 Measurements of length can't be negative. So its 3
h = 2(3) + 4 Substitute 3 in to find height
h = 10
