y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts
---
4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90
Answer:
(9-x)

Answer:
<h2>69.5</h2>
Step-by-step explanation:
Given the confidence interval of the heights of american heights given as (65.3,73.7);
Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7
Sample mean will be the average of both confidence interval . This is expressed mathematically as 
Hence, the sample mean is 69.5
