Answer:
175$
Step-by-step explanation:
Given that Pam is an employee at a jewelry kiosk in a mall. If Pam works hard, there is a 75% probability that jewelry profits will equal $400 a day and a 25% probability that jewelry profits will equal $200 a day. If Pam shirks, there is a 25% probability that jewelry profits will equal $400 a day and a 75% probability that jewelry profits will equal $200 a day.
Since Pam works hard
expected value of profit for the kiosk = ![400(0.75)+200(0.25)\\=350](https://tex.z-dn.net/?f=400%280.75%29%2B200%280.25%29%5C%5C%3D350)
From this value, 50% would be given to Pam
Hence expected gain for Pam for working hard
= ![0.5(350)\\=175](https://tex.z-dn.net/?f=0.5%28350%29%5C%5C%3D175)
175 $
Step-by-step explanation:
17. 21⁰ + 31⁰ + ?⁰ = 180⁰
= ?⁰ = 128⁰
18. ?² = 12² + 5²
? = √169
? = 13 TYPO
We can only assume that the order amounts are uncorrelated.
.. normalcdf(104, 150, 102, 8/√(5)) = .288075061
The probability is about 28.8%.

Step-by-step explanation:
elevation of 3,234 feet above sea level Positive This is above ground
losing $32.50 Negative it is less than you had
depositing $230 in an account Positive putting money in
withdrawing $2,432 from an account Negative taking money out
2°C below 0°C less than 0
