Answer:
6n + 7 = 7n
Step-by-step explanation:
Number of students involved in sports = 5n + 7
Number of students involved in student council = n
Number of students involved in sports and student council = (5n + 7) + n = 5n + 7 + n = 6n + 7
Number of students involved in band = 3n - 2
Number of students involved in drama club = 2(2n + 1)
Number of students involved in band and drama club = (3n - 2) + 2(2n + 1) = 3n - 2 + 4n + 2 = 7n
Equation to model number of students involved in sports and student council which equal number of students involved in band and drama club:
6n + 7 = 7n
The best and most correct answer among the choices provided by your question is the second choice or letter B "20".
The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000
14000=(120+x)(80+x)
14000=9600+200x+x^2
x^2+200x-4400=0
x^2-20x+220x-4400=0
x(x-20)+220(x-20)=0
(x+220)(x-20)=0, since x is an increase it must be greater than zero so
x=20ft
(120+20)(80+20)=14000ft^2

Answer:
$12.18
Step-by-step explanation:
Given:
Cost of 0.8 liter bottle of Mexican wine = 101 pesos
or
cost of 1 liter bottle of Mexican wine = 
pesos
Now,
1 Mexican pesos = 0.051 dollars
thus,
cost of 1 liter bottle of Mexican wine = 
dollars
also,
1 gallon = 3.78541 Liter
Thus,
half gallon = 
= 1.892705 Liters
therefore,
cost of half gallon jug = 
dollars
or
cost of half gallon jug of wine = $12.18
Answer:
0.003
Step-by-step explanation:
Since each of the policy have the same chance of success, then it follows a binomial distribution (only two outcome; success or failure).
α = √(p(1-p)/n) = √ (0.1 ( 1-0.1)/ 10000) = √ 0.000009 = 0.003
where p = 0.1, α = standard deviation.
