Sixty dash fivesixty-five percent of households say they would feel secure if they had? $50,000 in savings. you randomly select
Effectus [21]

 To solve the following problems, we use the binomial probability equation:

P (r) = [n!/(n-r)! r!] p^r q^(n-r)

where,

n = total number of households = 8

r = number of sample

p = probability of success = 65% = 0.65

q = probability of failure = 0.35

 

A. r = 5

P (r=5) = [8! / 3! 5!] 0.65^5 0.35^3

P (r=5) = 0.28

 

B. r >5

P (r=6) = [8! / 2! 6!] 0.65^6 0.35^2

P (r=6) = 0.26

P (r=7) = [8! / 1! 7!] 0.65^7 0.35^1

P (r=7) = 0.14

P (r=8) = [8! / 0! 8!] 0.65^8 0.35^0

P (r=8) = 0.03

Therefore total is:

P (r>5) = 0.26 + 0.14 + 0.03 = 0.43

 

C. r ≤ 5

P (r ≤ 5) = 1 - P (r>5)

P (r ≤ 5) = 1 – 0.43

P (r ≤ 5) = 0.57

How to get 75 using the numbers 7,5,6,and 3 only once
Arte-miy333 [17]
To get 75 using 7, 5, 6, and 3 only once:

= (7+5) * 6 + 3
parentheses first

= 12 * 6 + 3
multiplication before addition

= 72 + 3
= 75

Without being given any constraints, I'm assuming multiplication and addition were allowed.

Hope this helps! :)

4=2/4u one step equation
docker41 [41]
4 = 2/4u

Multiply both sides by 4u

16u = 2

Divide both sides by 16, and simplify.

u = 1/8
