All of the numbers in the set must either be less than 6 or greater than 10. They can't be between 6 and 10. The only set that works is {-3, 4.5, 13.6, 19}
Answer:
Option (d)
Step-by-step explanation:
From the given table,
Number of members in 1980 (t = 0) were 5400.
With the period of time number of members increased.
Let the number of years after 1980 = x
Therefore, line of best fit will be in the form of y = mx + b
Where b = Initial number of members = 5400
m = Increase in members in every 5 years duration
So the equation will be,
y = mx + 5400
From the given options,
Equation which matches to our equation is,
y = 310.58x + 5400
For the number of members in year 2022,
x = 2022 - 1980 = 42 years
y = 310.58(42) + 5400
y = 18445
Option (d) will be the answer.
The cost of company 1: 10x+50
The cost of company 2: 8x+60
The cost will be the same at:

Answer:
18 and 27
Step-by-step explanation:
Let x = first (smaller) number
Let y = second (larger) number
Sum of two numbers is 45:
⇒ x + y = 45
The greater number is 9 more than the other number:
⇒ y = x + 9
Substitute y = x + 9 into x + y = 45 and solve for x:
⇒ x + (x + 9) = 45
⇒ 2x + 9 = 45
⇒ 2x = 36
⇒ x = 18
Substitute found value for x into y = x + 9 and solve for y:
⇒ y = 18 + 9
⇒ y = 27
Therefore, the two numbers are 18 and 27
