Hey there! Let's figure this question out for you!
A math conjugate, is formed by changing the sign between two terms in a binomial.
An example would be:
4+7x would become 4 - 7x.
I hope this helps!
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57

Emily's number was 28
Step-by-step explanation:
the inner top vertex angle seems to be 90°, so x = 90° too. all angles around a single point in one side of a line are in total 180°.
also, remember, all angles inside a triangle always sum up to 180°.
so, the third inner angle of the triangle is
180 - 90 - 40 = 50°.
that makes z = 180 - 50 = 130°
and y = 180 - 40 = 140°.
Answer: $375
Step-by-step explanation:
Given : The probability of winning $100 : P(100)= 0.25
The probability of winning $200 : P(200)= 0.50
The probability of winning $1000 : P(1000)= 0.25
Now, the the expected value of that lottery ticket is given by :-

Hence, the the expected value of that lottery ticket =$375
