More than the twice of the mean is 28.8 and I don't understand the meaning of typical. Seeing this porblem statement said that 3 brands had been contaminated more than twice the average, We would assume it's typical, then again it depends on what you define typical as. I think the mean is like "find the probability that a tested bar has at least twice as many insect fragments as the mean, and see if that number is really really small".
The probability is 0.000463 and this is really small, but I really don't understand what is the meaning of typical in this problem.
Answer:
17 cm
Step-by-step explanation:
1. Depth in fresh water
p(water) = hρg
d(max) = h = p/(ρg)
Convert atmospheres to pascals
0.056 atm × 101 325 Pa/1 atm = 5670 Pa
h = 5670 Pa/(1000 kg·m⁻³ × 9.806 m·s⁻²) × (1 kg·m⁻¹s⁻²/1 N) = 0.579 m
2. Depth in Dead Sea
d(max) = 5670/(1400 × 9.806) = 0.413 m
3. Difference
Difference = 0.579 – 0.413 = 0.17 m = 17 cm
The difference in d(max) is 17 cm.
Cost of skateboard : $60
Cost of each lemonade = $1.50
Total glasses of lemonade to be sold = 60/1.5
= 60/15×10
= 4×10
= 40
Therefore she has to sell 40 glasses of lemonade

Answer:
and
Step-by-step explanation:
We require 2 equations with the repeating numbers placed after the decimal point.
let x = 0.1212...... (1) ← multiply both sides by 10
100x = 12.1212.... (2)
subtract (1) from (2) thus eliminating the repeating numbers
99x = 12 ( divide both sides by 99 )
x = = ← in simplest form
-------------------------------------------------------
let x = 0.037037....... (1) ← multiply both sides by 1000
1000x = 37.037037..... (2)
subtract (1) from (2) to eliminate the repeating numbers
999x = 37 ( divide both sides by 999 )
x = = ← in simplest form
