Answer:
Step-by-step explanation:
A) every 50 students is 1 representative, so:
r = (a+b+c+d+e)/50
b) (1587 + 985 + 2052 + 824 + 752)/50 = 6200/50 = 124 representatives.
Our answer makes sense since for every representative, there are 50 students. And 50*124 = 6200 total students.
Answer:
Seventy-five percent of the data values lie between 20 and 50.
Hope this helps
Sorry if I am wrong but I saw the answer in the internet
If correct can I get brainliest please
Step-by-step explanation:
Create a system of equations that includes one linear equation and one quadratic equation.
Part 1. Show all work to solving your system of equations algebraically.
Part 2. Graph your system of equations, and show the solution graphically to verify your solution.
y = x^2 + 3x + 5
y = x + 13
solution:
x^2 + 3x + 5 = x + 13
x^2 + 2x -8 = 0
(x+4)(x-2) = 0
x = -4 or x = 2
if x = -4, y = 9
if x = 2 , y = 15
hope this helps
