Answer:
Step-by-step explanation:
Set up two equations with the information given-- and things you know from experience: a penny is worth 1 cent and a nickel is worth 5 cents. $ 2.38 is 238 cents (so you can eliminate decimals for now)
Put those values into an equation about the total value:
p + 5n = 238
and you know the total number of coins is 66.
p + n = 66
get a value for p by "solving" (subtract n from both sides)
p = 66-n
Substitute that value for p in the first equation. Then solve.
(66 -n) + 5n = 238
4n = 238-66 Then isolate n by dividing both sides by 4
n = 172/4
n = 43 Substitute that in the second equation, then solve for p
p + 43 = 66 p = 66 - 43
p = 23
So Chuck has 23 pennies and 43 nickels

Answer:
(6, -2)
Step-by-step explanation:
Since <em>x = 4 and y = 3</em>, we can plug that into the second ordered pair: <em>(4 + 2, 3 - 5)</em>
Since 4 + 2 = 6 and 3 - 5 = -2, our new ordered pair is (6, -2)
Answer:
Null Hypothesis: The proportion of clients satisfied at the uptown office is 76%.
Alternative Hypothesis: There is no difference in the satisfaction between the uptown and the downtown clients.
Null Hypothesis: The proportion of clients satisfied at the downtown office is greater than the proportion of clients satisfied at the uptown office.
Alternative Hypothesis: Downtown clients are less satisfied with the dental office staff than uptown clients.
Null Hypothesis: The proportion of clients satisfied at the downtown office is 84%.
Alternative Hypothesis: Uptown clients are more satisfied with the dental office staff than downtown clients.
Null Hypothesis: The proportion of clients satisfied at the downtown office is equal to the proportion of clients satisfied at the uptown office.
Alternative Hypothesis: There is a difference in the satisfaction between the uptown and the downtown clients.
