They rented out 5 self-propelled mowers and 20 riding mowers.
Data;
- Total number of tool rented out = 25
- Cost of tools rented = $900
<h3>System of Equations</h3>
To solve this problem, we have to write a system of equations to represent the problem.
since we have
- x = self - propelled mower
- y = riding mowers
Let's write equations with these variables.

From equation (i)

Put equation (iii) into equation (ii)

Let's substitute the value of y into equation(i)

From the calculations above, they rented 5 self-propelled mowers and 20 riding mowers.

Answer:
Step-by-step explanation:
<u>7.5% less than 120 </u>
- 120 - 7.5% of 120 =
- 120(1 - 7.5/100) =
- 120*0.925 =
- 111
Answer:
20 times

40 divided by 2
Answer:
1.D) Procedure results in a binomial distribution.
2. B) Procedure results in a binomial distribution.
Step-by-step explanation:
The binomial distributions has following properties.
- There is always one of the two outcomes success or failure possible.
- The probability of p remains constant for all trials.
- The successive trials are all independent.
- The experiment is repeated for a fixed number of times.
If the experiment has the above properties it has binomial probability distribution.
In the given question both experiments have the above mentioned properties.
Both procedure result in binomial distribution.
