Sry that I can’t answer but I hope u have a great day
3n+5-6
Just simplify it, so now you have 3n-1
Let's go through each answer.
A) 3n+11 is incorrect because it does NOT equal 3n-1
B) 8n-6 is also incorrect because it does NOT equal 3n-1
C) 3n-1 IS correct because it DOES equal 3n-1
D) 3n+1 is incorrect because it does NOT equal 3n-1
So, your answer is C) 3n-1
~Hope I helped!~
160 - Percentage decrease =
160 - (2% × 160) =
160 - 2% × 160 =
(1 - 2%) × 160 =
(100% - 2%) × 160 =
98% × 160 =
98 ÷ 100 × 160 =
98 × 160 ÷ 100 =
15,680 ÷ 100 =
156.8
Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575
Z = (X - x_bar)/sigma
Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18
From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714
P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316
The correct answer is C.
