Can you type what it says I can't see it that well.
Okay, so there are nickels and pennies in this jar.
So, let's call the number of pennies X
Since there are 161 coins altogether, the number of nickels is (161 - X)
So now we solve the equation:
.01X + .05(161 - X) = 3.09
.01X + 8.05 - .05X = 3. 09
4.96 = .04X
124 = X
So, there are 124 pennies
Therefore, there are 161 - 124 = 37 nickels
Let's check our answer:
124 x .01 + 37x .05 = 1.24 + 1.85 = 3.09
It works!
Answer:
Step-by-step explanation:
1. Exchange rate = 1 U.S. dollar per 0.9009 foreign currency
i. U.S. Currency (in dollars) = 73.00
Foreign currency = 81.03
ii. U.S. Currency (in dollars) = 20.00
Foreign currency = 22.20
2. Exchange rate = 1 U.S. dollar per 1.3699 foreign currency
i. U.S. Currency (in dollars) = 30.00
Foreign currency = 21.90
ii. U.S. Currency (in dollars) = 50.00
Foreign currency = 36.50
3. Exchange rate = 1 U.S. dollar per 1.5873 foreign currency
i. U.S. Currency (in dollars) = 25.00
Foreign currency = 15.75
4. Exchange rate = 1 U.S. dollar per 1.11 Australian dollar
i. U.S. Currency (in dollars) = 72.00
Equivalent Australian dollar = 72.00 x 1.11 = 79.92

Solution
The z-score, also referred to as standard score, z-value, and normal score, among other things, is a dimensionless quantity that is used to indicate the signed, fractional, number of standard deviations by which an event is above the mean value being measured. Values above the mean have positive z-scores, while values below the mean have negative z-scores.
Mean is $650
Standard deviation = $50
