Answer:
0.34134
Step-by-step explanation:
In other to solve for this question, we would be using the z score formula
z = (x - μ) / σ
x = raw score
μ = mean
σ = Standard deviation
We are told in the question to find the probability that a worker selected at random makes between $350 and $400
let x1 = 350 and x2= 400 with the mean μ = 400 and standard deviation σ = $50.
z1 = (x1 - μ) / σ = (350-400) / 50 = -1
z2 = (x2 - μ) / σ = (400 - 400) / 50 = (0/50) = 0
From tables, P(z <= -1) = 0.15866
P(z <= 0) = 0.5
Then, the probability would give us, P(-1 ≤ z ≤ 0) =0.5 - 0.15866 =
0.34134
Hence, The probability that a worker selected at random makes between $350 and $400 = 0.34134
B. Love miss you have you too she got your
Answer:
x>-10
Step-by-step explanation:
(-9x-3) + 6 < 93
-9x-3+6 < 93
-9x + 3 < 93
-9x < 93-3 (subtracting 3 both sides)
Dividing by -9 both sides
x > 90/-9 ( switch the sign because dividing by a negative number)
x> -10 Answer
Hope this helps!
