Answer:
i think that it is 3.125
Step-by-step explanation:
because 1.75 + 1.375 =3.125
That answer is exponential!
We know that
density=mass/volume--------> volume=mass/density
step 1
find the volume of water
mass=700 kg
density of water=1000 kg/m³
volume of water=mass/density-----> 700/1000----> 0.70 m³
step 2
find the volume of ice
mass=450 kg
density of ice=916 kg/m³
volume of ice=mass/density-----> 450/916----> 0.49 m³
volume of water is 0.70³
volume of ice is 0.49 m³
<span>volume of the mixture is (0.70+0.49)-----> 1.19 m</span>³
the answer is
the volume of water is 0.70 m³
Answer:
2
Step-by-step explanation:
step 1
<span>compute the average: add the values and divide by 6
Average =(44+ 46+40+34+29+41)/6=39
step 2
</span><span>Compute the deviations from the average
dev: (44-39)=5,
</span>dev: (46-39)=7
dev: (40-39)=1
dev: (34-39)=-5
dev: (29-39)=-10
dev: (41-39)=2
step 3
<span>Square the deviations and add
sum (dev^2): 5^2+7^2+1</span>^2+-5^2+-10^2+2^2
sum (dev^2): 25+49+1+25+100+4-----> 204
step 4
<span>Divide step #3 by the sample size=6
(typically you divide by sample size-1 to get the sample standard deviation,
but you are assuming the 6 values are the population,
so
no need to subtract 1, from the sample size.
This result is the variance
Variance =204/6=34
step 5
</span><span>Standard deviation = sqrt(variance)
standard deviation= </span>√<span>(34)------> 5.83
the answer is
5.83</span>
