Step-by-step explanation:
Answer:
(A)12-19
Step-by-step explanation:
To construct a frequency distribution, we follow the steps below.
1. Find the largest and smallest values.
91 and 12 respectively
Compute the Range = Maximum - Minimum=91-12=79
2. Determine the number of classes desired.
In this case, we desire 10 classes
3. Next, we find the class width by dividing the range by the number of classes and rounding up.
79÷10 = 7.9
Rounded Up, Class Width=8
4. Pick a suitable starting point less than or equal to the minimum value.
Since our minimum value is 12, we pick a class starting with 12 and give a class width of 8.
Therefore the upper and lower limits of the first class is given as:
12-19.
Answer:
The expression for two times the difference of 4 and a number is

Step-by-step explanation:
To Find:
Write an expression for Eight times the difference of 4 and a number.
Solution:
Let the Unknown number be 'd'
Difference of 4 and d = ( 4 - d )
So One Time Difference of 4 and d = 1× ( 4 - d )
∴ Two Times Difference of 4 and d = 2× ( 4 - d )
∴ Eight Times Difference of 4 and d = 8× ( 4 - d )
The expression for Eight times the difference of 4 and d. will be

The expression for Eight times the difference of 4 and a number is

Answer:
450 cm^3 (Answer D)
Step-by-step explanation:
Volume of a rectangular box of dimensions L, W, H is V = L*W*H. The order in which these measurements are multiplied together is immaterial. Thus,
this particular box has volume V = (5 cm)(9 cm)(10 cm) = 450 cm^3
