Y = log (1/3) x
Part 1:
Domain : x ∈ ( 0, + ∞ ).
Range: y ∈ R.
General shape: The graph is decreasing.
Part 2 :
We will choose those points: x = { 1/3, 1, 3, 9 }
Ordered pairs ( for graphing the function ) are :
f ( x ) = { ( 1/3, 1 ), ( 1. 0 ), ( 3, - 1 ), ( 9, - 2 ) }.
There is no y - intercept and x - intercept is 1.
Answer:
no
Step-by-step explanation:

360 is the measure, in degrees of a pizza becasue it is a circle. There are two pizzas, or two circles. Each wedge is 40°, meaning that you need to divide the pizzas by the size of a wedge.
Hope I helped!
Answer:
E(x) = 7.05
Step-by-step explanation:
We are given the following information in the question:
x: 1 2 4 8 16
p(x): 0.05 0.10 0.30 0.40 0.15
Formula:

Hence, the expectation of the given data is 7.05
25 students got 2 chaperones
so 1 will get 2/25
and thus 8 will get 2/25×8 = 0.64 chaperone
but is it possible?? No chaperone can not be in decimal so at least 1 is required !!
