Answer:
6 weeks
Step-by-step explanation:
Easier way to solve: If she takes 7 quizzes each week, 7 times something (amount of weeks) equals 42.
7 X <u>6</u> = 42
Solving with algebra: We know that hanna takes six quizzes a week and takes a total of 42 quizzes, therefore the unknown (x) is the amount of weeks she takes the quizzes.
Amount of weeks X amount of tests per weeks = 42 quizzes
<em>x </em>X 7 = 42
42/7 = 6
Using it's concept, it is found that there is a:
- 0.6207 = 62.07% probability of selecting a cow.
- 0.0345 = 3.45% probability of selecting a horse.
- 0.3448 = 34.48% probability of selecting a goat.
- 0% probability of selecting a chicken.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there is a total of 18 + 1 + 10 + 0 = 29 animals, hence:
18/29 = 0.6207.
0.6207 = 62.07% probability of selecting a cow.
1/29 = 0.0345.
0.0345 = 3.45% probability of selecting a horse.
10/29 = 0.3448.
0.3448 = 34.48% probability of selecting a goat.
0/29 = 0.
0% probability of selecting a chicken.

Answer:
42 student tickets and 98 adult tickets
Step-by-step explanation:
Let's call the number of student tickets 's' and the number of adult tickets 'a'.
Then, we can write the two equations below:
5s + 8a = 994
a = 2s + 14
Using the value of 'a' from the second equation in the first one, we have:
5s + 8*(2s + 14) = 994
5s + 16s + 112 = 994
21s = 882
s = 42
Now, finding the value of 'a', we have:
a = 2*42 + 14 = 98
