Answer:
Total number of trees planted = 
trees
Step-by-step explanation:
Trees planted by each student = 
Total number of students = 
Using unitary method to find total number of trees planted by all the students in school.
1 student plants = trees
student would plant = 
We apply the product rule of exponents to multiply ![[a^xa^y=a^{x+y}]](https://tex.z-dn.net/?f=%5Ba%5Exa%5Ey%3Da%5E%7Bx%2By%7D%5D)
⇒ 
⇒ 
⇒ trees
Total number of trees planted = trees
Answer:
(5,-6)
Step-by-step explanation:
Answer:
Option D
Step-by-step explanation:
A reporter collects a random sample of 50 runners from all the runners who finished the Cherry Blossom Ten Mile Run in 2009 and constructs a 99% confidence interval for the true mean finish time to be (86.05, 99.38) minutes.
Assuming the reporter performed the calculations correctly, which of the following statements are appropriate interpretations of this confidence interval?
We can expect that 99% of confidence intervals created using the same method the reporter used will contain the true mean run time for runners of this race.
Sure I will give two examples
Application of tangents
1. If we are traveling in a car around a corner and we drive over something slippery on the round ( like water , ice or oil ) , our car starts to skid
It continue in a direction tangent to the curve
Application of tangents
2. Have you ever sat on a merry- go around
If yes , then you would understand
From your experience when I tell you that the force your experience is towards the centre of merry- go around but your velocity ( the tendency of motion) is in the way toward which your body pointing
Another way saying the same thing would be to let you know that your velocity at any point is tangent while force .
At any point is normal to the circle along which you are moving
Can you draw connection between both the ways of saying the same thing?
Have this two example help you
Good luck :D
