Answer:
Total number of quarters=10
Total number of nickels=19
Step-by-step explanation:
The expression for the total value of money you have is;
Quarters have a value of= $0.25
Nickels have a value of= $0.05
Total value=(value of quarters×number of quarters)+(value of nickels×number of nickels)
where;
Total value=$3.45
Value of a quarter=$0.25
number of quarters=x
Value of a nickel=0.05
number of nickels=y, but y=x+9
replacing;
3.45=(0.25×x)+0.05(x+9)
3.45=0.25 x+0.05 x+0.45
3.45=0.3 x+0.45
0.3 x=3.45-0.45
0.3 x=3
x=3/0.3
x=10
y=x+9=10+9=19
Total number of quarters=10
Total number of nickels=19
Answer:
Step-by-step explanation:
Given that a local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistently strings rackets at lower tensions, on average, than requested. To support this claim, the customer asked the pro shop to string 17 new rackets at 59 PSI. Upon receiving the rackets, the customer measured the tension of each and calculated the following summary statistics: sample mean = 56, standard deviation = 2.4 PSI.
Whenever we select alpha as 5% = 0.05 this means that whenever p value got from hypothesis test is less than this we reject null hypothesis. Otherwise we accept null hypothesis
C. The smallest value of p value that you can use and still reject H0 is 0 .05.
