Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given as:
Given that μ = $72,641 and σ = $30,000.
a) x > $100000
P(x > 100000) = P(z > 0.91) = 1 - 0.8186 = 0.1814
b) n = 5
x > $100000
P(x > 100000) = P(z > 2.04) = 1 - 0.9793 = 0.0207
c) n = 10
x > $100000
P(x > 100000) = P(z > 2.88) = 1 - 0.9980 = 0.002

Answer:
d>67
Step-by-step explanation:
Let's solve your inequality step-by-step.
−50−(−9d+7)>−d+10+9d
Step 1: Simplify both sides of the inequality.
9d−57>8d+10
Step 2: Subtract 8d from both sides.
9d−57−8d>8d+10−8d
d−57>10
Step 3: Add 57 to both sides.
d−57+57>10+57
d>67
