Answer with explanation:
Mean of the data set
= 112
Standard Deviation of the data set
=2.5
Since , 50% of data lies on both side of the mean.
Z at 50% = 0.1915
Margin of error for this data set
Margin of error=0.045(approx)

Step-by-step explanation:
m(−11+m)=0
Step 1: Simplify both sides of the equation.
m2−11m=0
Step 2: Factor left side of equation.
m(m−11)=0
Step 3: Set factors equal to 0.
m=0 or m−11=0
m=0 or m=11
Answer:
m=0 or m=11
Let x = # of original members
Cost per person (originally) = 832/x
Cost per person after 6 more people = 832/(x+6)
Solve 832/x=832/(x+6) +6 (because the cost was reduced by 6
Solve for x.
x = 26 or -32 (but x is number of members, so it can't be negative)
# of original members is 26.
Original cost is 832/26 = $32 per person.
Answer:
Slope = 1/2
y-intercept = 30
Equation : y = 1/2x + 30
D. 150 miles
Step-by-step explanation:
We can use the two visible points you marked on the graph.
They are (0,30) which is also the y-intercept and (20,40).
Calculate change of y over change of x.
10/20 or 1/2
So the slope is 1/2 and the y-intercept is 30.
Therefore, using y = mx + b form, the equation is y = 1/2x + 30
Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.
105 = 1/2x + 30
75 = 1/2x
x = 150
