Answer:

Step-by-step explanation:
Let x represent the number of lawns mowed and y represent the number of cars washed.
1. Since the number of cars that Beth wash is no more than four times the number of lawns Mike has scheduled to mow, you have that
.
2. Beth will wash at least 50 cars, then 
3. Mike charges $25 each time he mows a yard, then he earns $25x for mowing x yards. Beth charges $15 for each car she washes, then she earns $15y for y cars washed. They need at least $1975, so

4. A set of constraints to model the problem is

Answer:
0.06
Step-by-step explanation:
Total number of marbles:
6 + 10 + 5 + 1 = 22 marbles
Probability of picking 1 red marble:
red marbles / total marbles
6/22
Probability of picking a green marble:
green marbles / total marbles
5/22
Now, multiply the probabilities:
6/22 • 5/22 = 15/242 = 0.06
Answer:
87%>0.25>21%>0.2
Step-by-step explanation:
87% converted to decimal form is 0.87 which is greater than 0.25 and 21% converted to decimal form is 0.21 which is also greater than 0.2 which can also be interpreted as 0.20! Hope this helps!
Answer:
Best Player: 30
Second Best: 28
Third Best: 26
Step-by-step explanation:
1) Break the percents down into smaller increments - 5% for example.
2) 5% or 1/20 of 40 (the whole) is 2.
3) Using this knowledge, we know that a player who makes 5% of his throws makes 2 shots.
4) 75% is made up of 15 groups of 5%, so that means if you multiply 15 by 2 (the number of shots made for every group of 5%), then you get 30.
5) 70% is made up of 14 groups of 5%, so that means if you multiply 14 by 2 (the number of shots made for every group of 5%), then you get 28.
6) 65% is made up of 13 groups of 5%, so that means if you multiply 13 by 2 (the number of shots made for every group of 5%), then you get 26.
Answer: Compound probability is equal to the probability of the first event multiplied by the probability of the second event
