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
Answer:
What
Step-by-step explanation:
Answer:
Square pizza
Step-by-step explanation:
To obtain which pizza is the best buy:
Cost of square pizza :
AED 80
side length, s = 26cm
Area of square, A = s²
A = 26² = 676 cm²
1 AED of square pizza gives : 676 / 80 = 8.45 cm²
Cost of circular pizza :
AED 80
Radius, r = 28cm
Area of circle, A = πr²
A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²
1 AED of circular pizza gives : 616 / 80 = 7.7cm²
Hence, square pizza is the better buy ;
8.45cm² > 7.70 cm²
