Answer:
C. the mean increases more
Step-by-step explanation:
the mean is more affected by outliers because it is an average of all the numbers.
Answer: 66 because you are adding 2 then 4 then 6 then 8 then 10 then 12 therefore 17+10= 27, and 27+12= 39 and 39+27 equals 66
Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05
Hope that does something to help, even though this was posted a while ago
I must assume that you meant t=1 (not t=?1). If t=1, here's what we'd do:
1. Find the x and y values corresponding to t=1. They are:
x=(1)^7+1=2 and y=(1)^8+1=2. (Please note: write t^8 instead of t8, and write t^7 instead of t7.)
2. The slope of the tangent line to the graph is
dy/dt 8t^7+1
dy/dx = ---------- = ---------------- with 1 substituted for t
dx/dt 7t^6
Thus, dy/dx (at t=1) = 9/7
3. Now we have both a point (2,2) on the graph and the slope of the tangent line to the curve at that point: 9/7
4. The tangent line to the curve at (2,2) is found by using the point-slope formula:
y-y1 = m(x-x1)
which comes out to y-2 = 9/7(x-2), or 7y-14 = 9(x-2). You could, if you wished, simplify this result further (e. g., by solving for y in terms of x).
