Cole is an urban planner. He wants to create a small scale drawing of a city block. The block is a square with sides of length 1
Mashcka [7]
So if 11 units on the map is 5m in real life, the scale is 11 units= 5m
But we need 100m.
We would need 20 groups of 5m to get 100m.
So we would need 20 groups of 11 units, which is 220 units.
So, on the scale drawing, the square would need to be 220 units by 220 units.

1. The mean annual US household income is $72,641. Suppose that the standard deviation is $30,000. a. Find the probability that
valina [46]

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:

z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score,\mu=mean\ and\ \sigma=standard\ deviation \\\\For\ a\ sample\ size\ n: \\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }

Given that μ = $72,641 and σ = $30,000.

a) x > $100000

z=\frac{100000-72641}{30000}=0.91

P(x > 100000) = P(z > 0.91) = 1 - 0.8186 = 0.1814

b) n = 5

x > $100000

z=\frac{100000-72641}{30000/\sqrt{5} }=2.04

P(x > 100000) = P(z > 2.04) = 1 - 0.9793 = 0.0207

c) n = 10

x > $100000

z=\frac{100000-72641}{30000/\sqrt{10} }=2.88

P(x > 100000) = P(z > 2.88) = 1 - 0.9980 = 0.002
