7 7/8 - 3 1/4
7 7/8 = 6.125
3 1/4 = 0.75
so 6.125 - 0.75
= 5.375
as a mixed fraction the answer is 5 3/8
ANSWER: B. Associative Property of Multiplication
Answer:
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
Step-by-step explanation:
90% confidence interval
larger sample size = 20
condition : sample mean ( x-bar ) is the same for both samples
<em>This is a reasonable decision because the sample size has no effect on the 90% confidence interva</em>l
<u>from condition 1 :</u>
Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%
<u>for condition 2 :</u>
sample size = 20
mean = 2.25 ( assumed value )
std = 0.15 ( assumed value )
Z = 1.645 ( Z-value )
determine the 90% confidence interval
= mean ± z
= 2.25 ± 1.645
= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )
Answer:
So wavelength range of visible light will be to
Step-by-step explanation:
We have given wavelength range of visible light is 650 nm to 850 nm
We have given that
So for converting nm to cm to we have to multiply with
So 650 nm
And 850 nm
So wavelength range of visible light will be to
