Answer:
Population: All undergraduates who attend a university and live in the United States
Step-by-step explanation:
We are given the following situation in the question:
"A polling organization contacts 1835 undergraduates who attend a university and live in the United States and asks whether or not they had spent more than nbsp $200 on food nbsp in the last month."
For the given situation, we have
Sample size, n = 1835
Sample: 1835 undergraduates who attend a university and live in the United States
Variable: whether or not they had spent more than $200 on food in the last month
Thus, the population for this scenario will be
Population: All undergraduates who attend a university and live in the United States
49x^2 - 9 = 0
As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:
49 = 7^2
9 = 3^2
x^2 = (x)^2
so...
(7x - 3)(7x + 3) = 0
7x - 3 = 0 7x + 3 = 0
x = 3/7 x = -3/7
