The least common multiple of 5 and 12 is 60.
Answer:
40m³
Step-by-step explanation:
![\sqrt[3]{5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%7D)
= 1.709975947
1.709975947 × 2 = 3.419951893
3.419951893³ = 40
Answer:
R = 35l-215
Step-by-step explanation:
total amount they earn = 35l
however, to account for the money used to rent the machines, we have to deduct 215 from the total cost.
hence,
<u>R= 35l-215</u>
total amount they raised = 35(26)-215 = <u>$695</u>
they would lose <u>$215</u> if they were unable to aerate due to weather conditions
they could avoid this potential loss by <u>checking the weather report before renting the machines</u>
Answer:
By knowing the standard deviation, one gets the idea of how the value is scattered or dispersed about the mean.
Step-by-step explanation:
Let us first define standard deviation.
As it is known that the standard deviation is a measure of dispersion which express the spread of observation in terms of the average of deviations of observations from some central values.
Measure of dispersion gives us an idea about homogeneity or heterogeneity of the distribution.
Standard deviation is supposed almost an ideal measure of dispersion except the general nature of extracting the square root.
Thus for the given question, if we want to compare the two different groups of students whose mean score is 85. Here the standard deviation for both the groups interprets an idea about how the individual score for each group scattered or varied about the mean score i.e. 85.
