Answer: 51
Step-by-step explanation:
You divide both numbers
683.40 / 13.40
Answer:
Step-by-step explanation:
Answer with explanation:
Sample Size (n)=72
→P=% of people who listen to radio while they are at work =16 %
→B=1 - P= 100% - 16% =84%
→Standard Deviation when Probability and Sample Size is given
So, standard deviation of the sampling distribution of the proportion for the sample of size 72= 0.0432=0.043 (Approx)
Answer:
x=11
AB=45
BC=73
Step-by-step explanation:
AB+BC=AC, so...
4x+1+7x-4=118
Combine like terms
11x-3=118
Solve for x
11x=118+3
11x=121
x=11
Now put x in each equation
AB=4x+1=4(11)+1=44+1=45
BC=7x-4+7(11)-4=77-4=73
AC=45+73=118 (which was given!)
