4*x+7=12
4*x=5
x=5/4
The number is 5/4
Answer:
v= 1150.35 or v=143.79
Step-by-step explanation
if 6.5 is the radius then v= 1150.35 or if 3.25 is the radius then v=143.79
Range means highest value minus lowest value in a data collection
highest value = 18
lowest value = 2
Range = 18-2 = 16
First collect like terms for x^2:
x^2 + 3x^2 = 5x^2
Then collect like terms for x:
-2x + 5x = 3x
Collect like terms for normal numbers:
7 + - 3 = 4
Put them altogether:
5x^2 + 3x + 4
Answer:
As a statistical tool, a frequency distribution provides a visual representation for the distribution of observations within a particular test. Analysts often use frequency distribution to visualize or illustrate the data collected in a sample.
