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:
9 days
Step-by-step explanation:
Given isabella saves a nickel a day.From this day onwards she kept on incresing the savings by doubling them.
Here it form's a geometric progression with first term(a) = 1 and common ratio (r) = 2
S(n) =
Given condition is S(n) >500
n ≥ 9
So it will take 9 days for her savings to be more than 500
