Answer:
y = 24 /x
The operations used were: Multiplication and Division
Step-by-step explanation:
Let the number of students who shared the basket = x
Amount of oranges = y
Some students equally share 2 baskets of oranges. Each basket has 12 oranges.
The total number of oranges in basket = 2 baskets × 12 oranges
= 24 oranges
Therefore, the algebraic expression to represent this situation is written as:
y = 24 /x
The operations used were: Multiplication and Division

To factor our the following expression we proceed as follows;
p(x)=x^5-4x^3-2x^2-4x
factoring out x we get:
p(x)=x(x^4-4x^2-2x-4)
factoring further we get:
x^4-4x^2-2x-4
=(x+2)(x^3-2x^2-2)
Therefore our expression becomes:
p(x)=x(x+2)(x^3-2x^2-2)
Therefore the factors are x and (x+2) and (x^3-2x^2-2)
Okay so 3x-6(1/2x+4)=-12. 3x-3x-24=-12. x-24=-12.x=-36
Answer:
Yes. The city has a lower proportion of accidents by 16-year-old male drivers than the national proportion (16.7% compared to 21%).
Step-by-step explanation:
a) Data and Calculations:
Number of 16-year-old males involved in driver accident during year 2000 = 210
Sample number of drivers = 1,000
National rate of accidents for 16-year-old males for every 1,000 drivers = 21% (210/1,000 * 100)
Random sample of 16-year-old male drivers in a Midwest city = 150
Number of them involved in driver-accidents = 25
Proportion of 16-year-old males involved in driver-accidents = 25/150 * 100 = 16.7%
The city's 16.7% proportion is lower than the national proportion of 21%.
