In an isosceles triangle, there are two base angles and 2 sides that are congruent. The other congruent side and base have a 75 degree angle.
So base in your given that the function P(-d<z<d)=0.5408, the ask is to find the value of D by standard normal distribution. Base on my calculation and analyzing the equation the possible answer to this question is D=0.2704, i hope you are satisfied with my answer and feel free to ask for more
Answer:
Step-by-step explanation:
We have the following properties:
So, if we have that E[X(X-1)] = 27.5, we can write them using the first property as:
Then, replacing E(X) by 5 and solving for , we get:
Finally, using the second property and replacing by 5 and by 32.5, we get that V(X) is equal to:
Answer:
-2x+y = 4
y = 2x+4
Slope = 2 y-intercept = 4
