N•2>8
then dive both sides 2n>8
and get n>4
Answer:
See below
Step-by-step explanation:
If a function is bijective and 1-to-1, then it will have an inverse function. Consequentially, they will be symmetrical about the line
, which is a diagonal line passing through the origin at a 45 degree angle.
None of the graphs look correct though, but it also seems that some options are cut out, so make sure to choose the correct graph given the characteristics I've previously described.
The sample mean is the sum of the sample values divided by the number of them:
(7 +7 +10 +6 +9 +6 +8 +7.5 +8.5 +8)/10 = 77/10 = 7.7
The sample mean is 7.7.
Answer:
x ≈ 12.9
Step-by-step explanation:
In relation to the angle in this right triangle, the sides marked are the adjacent side and the hypotenuse. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(72°) = 4/x
Multiplying by x/cos(72°), we have ...
x = 4/cos(72°)
x ≈ 12.9
