Example 1 – Constructing a frequency distribution table
Divide the results (x) into intervals, and then count the number of results in each interval. ...
Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.
Answer:
C
Step-by-step explanation:
3 1/2 times -(4/5)
First multiply 3 1/2 and -(4/5)=2 4/5
Answer:
Expression that represents the length of one side of the square is x - 5.
Step-by-step explanation:
Given,
Area of the Square = ( x² - 10x + 25 ) m²
We have to find: Length of the side of the square.
Let s be the side of square.
We find length of side of the by using factorization.
According to the question,
s² = x² - 10x + 25
s² = x² - 5x - 5x + 25
s² = x( x - 5 ) - 5( x - 5 )
s² = ( x - 5 )( x - 5 )
s² = ( x - 5 )²
Taking square root on both sides we get,
s = x - 5
Therefore, Expression that represents the length of one side of the square is x - 5.
Answer:
324 square inches
Step-by-step explanation:
In this case;
we are given a trapezoidal heart;
Height is 12 inches
Bases are 24 inches and 30 inches
We are required to determine the space the trapezoidal heart will take;
We are going to determine its area;
Area of a trapezoid is given by;
Area = 0.5 h (a +b)
where a and b are the bases
Therefore;
Area = 0.5 × 12 (24 + 30)
= 324 square inches
Therefore, the trapezoidal heart will take up an area of 324 square inches
