Well you see if you calculate 3.2 times 2 that will equal 6.4 but then if you divide that by 2 that will give you 3.2 so basically your answer is 6.4
The volume of the bucket will be given by:
v=πr²h
Thus the volume of our bucket will be:
v=3.14×(3.5)²×8
v=46.465 in³
thus the cost of the bucket will be:
cost=(cost per cubic volume)×(volume of bucket)
cost=46.465(0.05)=$2.32325~$2.30
Answer:
$360.
Step-by-step explanation:
Given that 5 liters of a solvent cost $ 72 per liter, to determine the value of 5 liters of solvent the following mathematical calculation must be carried out, consisting of multiplying the value per liter by the number of liters to be purchased:
72 x 5 = X
360 = X
Therefore, the 5 liters of solvent will have a cost of $ 360, that is, five times the value of the liter, which is $ 72.
Answer:
the required number of samples to contain the population mean = 136
Step-by-step explanation:
From the Empirical rule, If a data is normally distributed, then about 68% of the population lies within one standard deviation from mean.
Now, if we suppose that the mean of a normally distributed population is 300, and 200 simple random samples are drawn from the population. i.e. μ = 300
And;
Number of simple random samples: n = 200
Thus, by implication, we would expect about 68% of 200 samples confidence intervals to contain the population mean .
Hence,
Required number of samples = 68% of 200
This gives ;
0.68 x 200 = 136
Thus , the required number of samples = 136
(-5,-3)! the third quadrant is the lower left of the coordinate plane. hope that helps!
