(a) $2000
(b) $94.9
Step-by-step explanation:
The expected $ value of signing 100 deals with probability of 0.1 each is
E(X) = 100*0.1 + 100*0.1 + 100*0.1 + ... + 100*0.1 = 100(100*0.1) = $1000
Along with the fixed amount of $1000, the total next month salary is $2000

Step-by-step explanation:
Given:
The figure of two quadrilaterals.
In
In
To find:
Whether the figures are congruent, similar or neither.
Solution:
Ratio of corresponding sides are:
Similarly,
And,
Clearly, .
All corresponding sides are not proportional.
Therefore, the figures are neither similar nor congruent. Hence, third option is correct.
