B, 33%
Step-by-step explanation:
Let us find the original price of four chairs without the special deal, and <u>compare</u> it with the deal to find the percent savings.
Step 1:
A customer must buy 4 chairs costing $75 each to recieve the deal. Let us <u>multiply</u> 4 by 75 to find the total cost without the deal:
Step 2:
We now know the original cost of the 4 chairs, and the price of 4 chairs with a deal. Let us <u>subtract the difference of costs</u> and convert it into a <u>percentage</u> to find percent savings:
%
<u>Therefore, B, the percent savings is 33%.</u>

Remember, negative numbers are lower than positive numbers, and the greater a negative number's distance from zero, the lower it is.
Answer: 20ways
Step-by-step explanation:
Number of candies = 7
Number of kids = 4
Since each kid must receive at least one candy ;
Therefore number of candies left to ration is
7 - 4 = 3 candies ; among 4 kids.
To share 'n' identical object among 'r' number of individuals can be expressed in the form :
[n+(r-1)Cr-1]
n = 3 ; r = 4
[3+(4-1)C4-1] = 6C3
Recall: nCr = n! / (n-r)!r!
6C3 = 6!/(6-3)!3!
6C3 = 6!/3!3!
= (6 * 5 * 4) / (3 * 2 * 1)
= 120 / 6
= 20ways
The mean is the unit of center that may be used to predict how many strokes will be needed to complete the ninth hole.
The data is almost symmetrical, making the mean the best option.
What is symmetrical data?
- Asymmetric communications refers to any system where, when averaged over time, the data speed or amount is different in one direction from the other.
- Asymmetry is defined as the lack of precise similarity between two pieces.
- A fiddler crab's body is asymmetrical, as evidenced by the fact that one of its claws is larger than the other.
- Absence of a standard unit of measurement between two things or amounts; incomprehensibility.
So the more about symmetrical visit.
