Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
Answer:
19
Step-by-step explanation:
When you have a straight line with a transversal, the two angles are equal to 180 degrees
180=123+3x ---> subtract 123 to the other side
57=3x ---> divide by 3
x=57/3
x=19

Answer: 512m³
Step-by-step explanation:
v = whl
The volume for left building:
v = w x h x l
v = 4 x 10 x 8
v = 320 m³
The volume for right and lower building:
v = w x h x l
v = 8 x 4 x 6
v = 192 m³
The total volume for the entire Charter School is: 320m³ + 192m³ = 512m³
