So what is given is:
length = 1.9 * w, you want to convert this to w = ...
This is done by dividing left and right by 1.9, so you get:
length/1.9 = 1.9*w/1.9, which simplifies to w = length/1.9
Another approach is to replace the multiplication with a simpler one in your head. So in stead of reading "length = 1.9 * width, what is width?", you read "6 = 2*3, what is 3?". You'll immediately realize 3 = 6/2, and that shows you how to change the real equation, ie., width = length/1.9.
Answer:
If you have written the sides of both triangles in the same order , The congruent side will be ED . Else it could be anything . It would be more better if you could put a figure
Answer:
u+v=7-7i
u-v=3+3i
Step-by-step explanation:
u+v
(5-2i)+(2-5i)
Put like terms together:
(5+2)+(-2i-5i)
Simplify:
7+-7i
7-7i
u-v
(5-2i)-(2-5i)
Distribute:
(5-2i)+(-2+5i)
Put like terms together:
(5-2)+(-2i+5i)
3+3i
In Binomial distribution, the expected value or mean is given by,
E(X) = np
where, p = probability of success and n=number of sample size.
E(X) = 100×0.4 = 40
