Answer:9 nickels and 19 dimes.
Step-by-step explanation:
Let
be the number of nickels Kay has.
Let
be the number of dimes Kay has.
Value of
nickel is $
Value of

Value of
dime is $
Value of
nickels is $
Given that Kay has a total of

So,
...(i)
Given that Kay has a total value of $
So,
...(ii)
Using (i) and (ii),


4g/cm^3
D = M/V
100g/25cm^3 = 4g/cm^3
Answer:
There is enough evidence to reject the manufacturer’s claim and the standardized test statistic z is -3.43
Step-by-step explanation:
A manufacturer of sprinkler systems designed for fire protection claims that the average activating temperature is at least 135°F.
So, Null hypothesis:
Alternate hypothesis :
To test this claim, you randomly select a sample of 32 systems and find the mean activation temperature to be 133°F.
x=133
n = 32
Population Standard deviation =
Formula :

z=-3.43
Refer the z table for p value
p value = 0.0003

p value < α
So, we failed to accept null hypothesis
Hence there is enough evidence to reject the manufacturer’s claim and the standardized test statistic z is -3.43
