Answer:
Step-by-step explanation:
All but the x- and y-intercepts are the same.
Answer:
Table 3
Step-by-step explanation:
Data shows no correlation when it has no trend in relation to the x-values. The data of table 3 both increases and decreases as x gets larger, so shows less correlation than the other tables.
This is verified by the computation done using a spreadsheet.
Table 3 shows no correlation
Because 115 is on a line and a line equals 180, subtract 115 from 180 and you get x=65
Answer: 10
Step-by-step explanation:
Since integral from 1 to 4 of f(x) =10
To evaluate integral from 2 to 8 of 2 times f(2x), using substitution method
Let U = 2x, dU = 2dx, dx = dU/2
Evaluate the limit, upper limit gives dU = 2*4 = 8, lower limit gives dU = 2*1 = 2.
Since this limit are the same as the limit for the question,
Therefore, F(4) - F(1) = F(8) - F(2) = 10
Substituting dx=dU/2
Gives,
Integral from 2 to 8 of 2 times f(2x)= (1/2)(2)(F(8)-F(2)) = 10
Answer:x+y+z=180
Since y+z=5x, x+5x=180, so x=30
So,
30+y+z=180
y+z=150
Since z=y+24, y+y+24=150
2y=126
y=63
30+63+z=180
z=87
So x=30, y=63, z=87
