Answer:
15%
Step-by-step explanation:
37.5% of the 40% of students who walk have been late, so ...
0.375 · 0.40 = 0.1500 = 15%
of the students in the school both walk and have been late.
The probability that the student selected walks and has been late is 15%.
Replace w with 10 and solve for a:
10 = (a-7000/2000 + 2)
Subtract 2 from both sides:
8 = a-7000 /2000
Multiply both sides by 2000:
16,000 = a-7000
Add 7000 to both sides:
a = 23,000
You can climb 23,000 feet
The explanation is replacing w with the number of weeks ( 10) and solving for a. You can then check by replacing a with the solution and solving for w.

<h3>What is unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Jessica takes a horse 3.31 kilometers
Through a motorcycle she travel 1 kilometer.
So, the total distance travelled
=3.31 + 1
=4.31 Km
Hence, the total distance they travelled is 4.31 Km.
