Answer:
18/5 = 3.6 so we would round the number to make it 4 times
Step-by-step explanation:
divide 18 by 5.
let's say you had 18 apples and you have to give 3 people the same amount of apples. If we give 5 apples to each of the 3 people, we would have given them a total of 15 out of 18 apples, that would leave 3 apples. You would then give each person 1 of the 3 apples so that all the people have the same amount of apples.
So if you count the total apples each person had, it would be 4. So we know that the answer is 4 because each apple represents how many times the apples to apples each.
Answer: Rahul walks 2.7 km more than Vansh.
Step-by-step explanation:
The options include:
a. Vansh walks 7.2 km more than Rahul.
b. Vansh walks 2 km more than Rahul.
c. Rahul and Vansh both cover the same distance.
d. Rahul walks 2.7 km more than Vansh.
Distance covered by Rahul weekly = 9km
Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km
From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.
Note: 1000 meters = 1 kilometers

Explanation;
-According to this type of tax system, the taxes assessed are based on the taxable amount, and follow an increasing schedule. High-income earners pay more than low-income earners, and the tax rate, along with tax liability, increases as an individual or entity's wealth increases.
-Therefore; higher earners pay a higher percentage of taxes and more money in taxes than do lower-income earners

Answer:
a) Decrease
b) New mean = 78.43
c) Decrease
Step-by-step explanation:
We are given the following in the question:
Total number of students in class = 28
Average of 27 students = 79
Standard Deviation of 27 students = 6.5
New student's score = 63
a) The new student's score will decrease the average.
b) New mean
New mean =
Thus, the new mean is 78.43
c) Since the new mean decreases, standard deviation for new scores will decrease.
This is because the new value is within the usual values i.e. within two standard deviations of the mean. So, this wont cause a lot of variation as this value will be closer to already available data values. Also number of observations (n) in the denominator is increasing. Based on both these points we can conclude that standard deviation will decrease
Formula for Standard Deviation:
where 
are data points, 
is the mean and n is the number of observations.
