With this asap
during the summer my father and i both work for my brother at lakeland golf course. most mornings my dad mows greens starting at 5: 45 a. m. the greens are mowed a little differently each day, as explained below.
1) the middle of each green is mowed at either 10: 00, 12: 00, 2: 00, or 3: 00
2) then one pass is mowed around the edge of the green. that pass is mowed:
a. either all the way out to the edge or in about 6 inches, and
b. with either the left reel out (clockwise) or the right reel out (counterclockwise)
my first question for you is this; how many different ways are there to mow a green? write down your answer and write a couple of sentences explaining how you came up with your answer.
next, find the probability that one randomly selected day the greens are mowed:
i) at 10: 00?
ii) with the left reel out (clockwise)?
iii) at 12: 00 and about 6 inches in from the edge?

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
