Answer:
5/4
Step-by-step explanation:
, open the bracket
3=28-14u-6u
Collect like terms
3-28=-14u-6u
-25 =-20u
Divide both side by -20
u=-25/-20. Minus sign will cancel each other and reduce to the lowest term
u=5/4

Answer:tickets in Germany cost $8.93
tickets in France cost $8.85
Step-by-step explanation:
Let x represent the cost of a movie ticket in Germany.
Let y represent the cost of a movie ticket in France.
Four movie tickets in Germany plus 3 movie tickets in France cost &62.27. This means that
4x + 3y = 62.27 - - - - - - - - 1
three tickets in Germany plus 4 tickets in France cost $62.19
This means that
3x + 4y = 62.19 - - - - - - - - -2
Multiplying equation 1 by 3 and equation 2 by 4. It becomes
12x + 9y = 186.81
12x + 16y = 248.76
Subtracting,
- 7y = - 61.95
y = - 61.95/7
y = 8.85
Substituting y = 8.85 into equation 1, it becomes
4x + 3×8.85 = 62.27
4x + 26.55 = 62.27
4x = 62.27 - 26.55
4x = 35.72
x = 35.72/4 = 8.93
Answer:
Step-by-step explanation:
ported that 22% of adults in France admitted to texting or e-mailing while driving. A random sample of 110 French adults was randomly selected. What is the probability that 26
Using a binomial distribution with mean = n*p = 110*0.22 = 24.2 and variance = n*p*(1-p) = 24.2*(1-0.22) = 18.876
Approximating it to a normal distribution,
