Answer:
A, D and E
Step-by-step explanation:
A.
Subtract 3 from both sides
B.
Add 1 to both sides
C.
Multiply through by z
Divide through by 20
D.
Divide through by 12
E
Subtract 12 from both sides
Hence:
A, D and E answers the question
9514 1404 393
Answer:
π square inches
Step-by-step explanation:
The area of the whole circle is ...
A = πr²
A = π(2 in)² = 4π in²
A 90° sector is 1/4 of the circle, so its area is ...
(1/4)(4π in²) = π in²
Given:
μ = 2 min, population mean
σ = 0.5 min, population standard deviation
We want to find P(x>3).
Calculate the z-score
z= (x-μ)/σ = (3-2)/0.5 = 2
From standard tables, obtain
P(x ≤ 3) = P(z ≤ 2) = 0.9772
Therefore
P(x > 3) = P(z > 2) = 1 - 0.9772 = 0.0228
Answer: 0.02275
y<-5/3x+25 Is your answer. To get it you subtract the 5x to both sides and then you divide the 3 on both sides
answer : y < -5/3x +25
