Answer:
a 2.68
b 2.01
Step-by-step explanation:
1.34/2 =( 0.67 (F) )
(F)*4 = A
(F)*3 = B
F(1)=4(1+1+7)-2(1)+8-4
f(1)=36+2
f(1)=38
f(2)=4(2+2+7)-2(2)+8-4
f(2)=44
C. The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.
The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. Since classes have different numbers of students, one may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample because it doesn't represent the students correctly.

Answer: x+y =12
0.40x+0.50y =5.70
Step-by-step explanation:
Let x = Number of ears of yellow corn
y - Number of ears of peaches and cream variety.
AS per given,
x+y = 1 dozen
⇒ x+y =12 [1 dozen =12]
Cost per ear of yellow corn = 40 cents = $0.40 [1 dollar = 100 cents, 1 cent = 0.01 dollar]
Cost per ear of peaches and cream variety = 50 cents = $ 0.50
Total cost ( in$): 0.40x+0.50y =5.70
Required system of equations represents the number of ears of corn of each type that Larji purchased:
x+y =12
0.40x+0.50y =5.70
