Recall the relation:
8 oz =1 cup
so,
1 oz = 18cup
Therefore,
16 oz = 168cup
= 2 cups
Hence, she should measure 2 cups to get 16 oz.
Answer:
critical value = 1.645
The 90% confidence interval = ( -22.62, -17.58)
Step-by-step explanation:
Given that:
the sample size
= 178
the sample size
= 226
the sample mean
= 54.4
the sample mean
= 74.5
population standard deviation
= 18.58
population standard deviation
= 9.52
level of significance ∝ = 1 - 0.90 = 0.10
The critical value for
is 1.645
For the construction of our confidence interval, we use 90% since that is used to find the critical value.
∴
The margin of error = 



2.52
The lower limit = 
= ( 54.4-74.5) - (2.52)
= -20.1 - 2.52
= -22.62
The upper limit = 
= ( 54.4-74.5) + (2.52)
= -20.1 + 2.52
= -17.58
The 90% confidence interval = ( -22.62, -17.58)
Hello!
We solve this algebraically
y + 6 = 3/2(x - 4)
We distribute the 3/2
y + 6 = 3/2x - 6
If you work with decimals easier we can make 3/2 into a decimal
y + 6 = 1.5x - 6
Add 6 to both sides
y + 12 = 1.5x
subtract y from both sides
1.5x + -y = 12
Hope this helps!

It would strike <span>672 times. To figure this out all you would do is look up how many minutes is in a week and the divide that number by 15. Hope this helps!</span>
