Answer:
x=180-(67+52)
Step-by-step explanation:
a linear pair is 180
we are already have two angles add them together
subtract that from 180 and you will get the last angle
Answer:
Option C
Step-by-step explanation:
WE are given a graph of exponential function and asked to find out of four functions which function the graph represents.
We find that any function of the form
passes through (0,1) for all a
Hence we cannot distinguish any thing from the point
Let us consider when x=1
Then first function will have point as (1,2.4)
II funciton (1,0.31)
III function (1,0.45)
IV funciton (1,1.8)
From the graph given we find that the point of y is less than 1. Hence it can be either II or III
Consider x=-1
Then II function has point as (-1,3.225) and III function has point as (-1,2.222)
From the graph we find that the graph satsified only the point (-1,2.2222)
Hence OPtion III is right
We can do this from finding 2/3, and that equals 0.66_7 and 7/12 is 0.5833_ and we divide the whole thing. 41.66 and 4.5833 and we get 11
The expected value of the discrete distribution is of 20.97, hence option C gives the correct answer.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability.</u>
Hence, according to the table, the expected value is given by:
E(X) = 12 x 0.08 + 18 x 0.15 + 20 x 0.31 + 22 x 0.08 + 24 x 0.15 + 25 x 0.23 = 20.97.
