Answer:
13.3
Step-by-step explanation:
There is an equation that helps
mean= (All of the numbers in the data added) divided by (the number of numbers in the data)
What that mean is:
1.) Add 20, 5, 7, 17, 16, and 15
2.) divided by 6 (because there is 6 numbers in the data)
3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)
which in this case it should be 13.33333...=13.3
I think it is 989 or 899
*3 digit number*
*26 sum*
Last two digits are the same
Y=-4/2x-3 that should be a correct answer
Answer:
x=-3
Step-by-step explanation:
Since f(x) also means y, we are looking for a point where y=3
When x=-3, we see that y reaches 3
Therefore, the answer is x=-3
For that case the new circumference is:
C = 9 - 2
C = 7 inches
By definition, the circumference is:
C = 2 * pi * r
Where,
r: radio
Substituting values:
7 = 2 * pi * r
Clearing the radio:
r = 7 / (2 * pi)
Then, the diameter is:
d = 2 * r
Substituting:
d = 2 * (7 / (2 * pi))
d = 2.228169203
Round to the hundredth:
d = 2.23 inches
Answer:
The diameter of the roll after the decrease is:
d = 2.23 inches
