Answer:
-$1.8
or loss of $1.8
Step-by-step explanation:
Given the following parameters, we have
The probability of winning $4 is 3/16
The probability of winning $7 is 2/16
The probability of losing $5 is 11/16
E(X) = (4 * 3/16) + (7 * 2/16) + (-5 * 11/16)
= 12/16 + 14/16 - 55/16
= -29/16
= -1.8
Hence, your expected net "winnings" would be -$1.8. That's an expected loss of $1.8.
The answer I believe it will be 2/7 I think
a salesperson earns $175 per week plus a commission equal to 4% of her sales. This week her goal is to earn no less than $525.
Let x be the amount of sales in dollars
Commission = 4% of her sales x = 4% of x = 0.04 * x= 0.04 x
a salesperson earns $175 per week + 0.04 x
so Amount of earning in a week = 0.04 x + 175
This week her goal is to earn no less than $525.
So amount of earning is greater than 525
0.04 x + 175 >= 525
The required expression is 0.04 x + 175 ≥ 525
h=(a)(sinC)=19(sin37)
That means h ≈11.43
Since c<h, There is no triangle
