A mean is just another word for average. We get the average by adding up all the data number and dividing this sum by the number of data numbers there are.
So that list all added up is 40, and since there are 10 numbers, we divide 40 by 10, which gives us a mean of 4 people per household.
First you would do 1.95 * 3 which would equal to 5.85, then you would do 10.00-5.85 which equals to 4.15
Answer: She would receive $4.15 as change if she payed with a $10 bill.
Answer:
3√2
Step-by-step explanation:
Given the following;
DB = 3
CD = 6,
Required
find AD.
using the similarity property of a triangle
DB/AD = AD/CD
3/AD = AD/6
3*6 = AD²
18 = AD²
AD = √18
AD= √9*√2
AD = 3√2
Hence the measure of AD is 3√2
Step-by-step explanation:
In trapezoid ABCF, AB || CF.
Therefore, parallelograms ABEF & ABCD have same height and lie on the same base AB.
From equations (1), (2) & (3), we find:
Thus, the two triangular pieces of land are equal in area.
Hence proved.
Answer:
English statement 'two more than a number equivalent to Y' can be algebraically represented as:
Step-by-step explanation:
Two more than a number means we need to add 2 to a number.
- Let suppose the number be = x
- Two more than the number 'x' = x+2
- As it is stated that two more than a number equivalent to Y.
Equivalent means something is equal to the given expression.
- Mathematically, the 'equivalent' is represented by the symbol '='.
Thus, the English statement 'two more than a number equivalent to Y' can be algebraically represented as:
