Answer:
n=11
Step-by-step explanation:
(n+4)/10 = (n-8)/2
We can solve using cross products
(n+4) * 2 = 10 * ( n-8)
Distribute
2n+8 = 10n -80
Subtract 2n from each side
2n+8-2n = 10n-80-2n
8 = 8n-80
Add 80 to each side
8+80= 8n-80+80
88 = 8n
Divide each side by 8
88/8 = 8n/8
11 = n
The actual distance between Yappy city and Quiet city when it is 23 cm in map is 9.2 miles.
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that :
The distance on the map between Yappy city and Quiet city is 23 cm
and,
5cm = 2 miles
now, for 1 cm on map it is equal to 2/5 miles of actual distance.
Therefore to find the actual distance of 23 cm in map we simply multiply 23 with 2/5 :
actual distance :
2/5 x 23 = 9.2 miles
Therefore, the actual distance between Yappy city and Quiet city is 9.2 miles.

Answer:
Masters = 59,000
Bachelors = 54,000
Step-by-step explanation:
Given that:
individual whose final degree is a masters is $49 thousand less than twice that of an individual whose final degree is a bachelors
Let masters salary = m
Bachelors salary = b
m = 2b - 49000 - - - (1)
m + b = 113,000 - - - (2)
From (2)
m = 113,000 - b
Substitute m = 113,000 - b into (1)
113,000 - b = 2b - 49000
113000 + 49000 = 2b + b
162000 = 3b
b = 162000/3
b = $54000
Hence,
Masters salary :
m = 113,000 - b
m = 113,000 - 54,000
m = 59,000

Answer:
40%
Step-by-step explanation:
If we call by A the members that prefer swimming on weekends and by B the members that are women, we have that:
P(A) = 0.25
P(A and B) = 0.1
The probability of a member being female given that the person prefers swimming on weekends can be expressed as P(B|A) (that is, probability of B given A).
To find this value, we can use this formula:
P(B|A) = P(A and B) / P(A) = 0.25
So we have that:
P(B|A) = 0.1 / 0.25 = 0.4 = 40%
