2980 round everything to the nearest tens and add with your head to get it
You can use (-25,-5) it fits the equation and it’s in the solution set
Answer:
18.84
Step-by-step explanation:
Circumference = 2πd
where d = diameter
the shape given has a diameter of 6
to find the circumference we simply plug in the value of the diameter as well as π into the formula
formula : C = πd
π = 3.14 and d = 6
C = 3.14(6) = 18.84cm
9-1a/2 = 5+4a
-5 -5
4-1a/2 = 4a
+1a/2 +1a/2
4 = 9a/2
*2 *2
8 = 9a
/9 /9
8/9 = a

Answer:
1 quantitative
2 32 responded yes, 18 responded no
3 margin error 32%{n}
4 error of students on their phone / not
5 18/-/50
6 16%
7 2%
Step-by-step explanation:
a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time.
The margin of error tells you the range of values above and below a confidence interval.
