Answer:
An estimate
Step-by-step explanation:
------------------------------------------
Define adult and student tickets
------------------------------------------
Let the number of adult tickets be x
Adult tickets = x
Student tickets = x + 69
------------------------------------------
Form equation and solve for x
------------------------------------------
x + x + 69 = 569
2x + 69 = 569 ← Combine like terms
2x = 569 - 69 ← Subtract 69 from both sides
2x = 500
x = 250 ← Divide by 2 to find x
------------------------------------------------------------------------------------
Find the number of adult tickets and student tickets
------------------------------------------------------------------------------------
Adult tickets = x = 250
Student tickets = x + 69 = 319
------------------------------------------------------------------------------------
Answer: Adult tickets = 250 ; Student tickets = 319
------------------------------------------------------------------------------------
The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.
Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r
Total spend, s(r): 30 + 2r
Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5 ----- this is the function notation
Standard form: s(r) is the dependent variable = s
s = 30 + 2r => s - 2r = 30 =>
s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form
Answer:
(A) the specific number of siblings for each randomly selected student
Step-by-step explanation:
First Timothy wants to estimate the mean number of siblings for each student in his school
So he selected a random sample of 75 students, then recorded the number of siblings they have
He later find the mean.
You can see the mean was obtained from the selected group not all students in the school hence option D and E are not correct.
Option A clearly indicates a mean was obtained for the siblings that were from the randomly selected students.
