Answer: 19 days
Step-by-step explanation:
305-115=190
190 divided by 10= 19
I think the answer isssss 2795
One cubic yard is equal to 27 cubic feet because one yard is equal to 3 feet
<em><u>Solution:</u></em>
Given that, there 27 cubic feet in one cubic yard
Yard and feet are units of distance
1 Yard (yd) is equal to 3 feet (ft). To convert yards to feet, multiply the yard value by 3.
<em><u>The conversion factor for 1 yard to 1 feet is given as:</u></em>
Now find for 1 cubic yard . Cubic yard means yard raised to power 3
Therefore,
Thus one cubic yard is equal to 27 cubic feet
Therefore, there are 27 cubic feet in one cubic feet
Answer: 1.013
Step-by-step explanation:
Given the following data :
X_______f___fx___fx²
1_______15__15___15
2______30__60__120
3______28__84__252
4______10__40___160
______ 83__199__547
Number that is 1.5 standard deviations below the mean :
Mean(m) :
Σfx /Σf
(15 + 30 + 28 + 10) / 83
= 199 / 83
= 2.3976
Standard deviation(s) :
Sqrt[(Σfx² - (Σfx)²/Σf) /Σf-1]
sqrt[(547 - (199)²/83) / 83 - 1]
sqrt[(547 - (39601/83) / 82]
sqrt[(547 - 477.12) / 82]
sqrt(0.8522)
Standard deviation = 0.9231
1.5 standard deviations below the mean:
Mean - 1.5(standard deviation)
2.3976 - 1.5(0.9231)
2.3976 -1.38465
= 1.01295
= 1.013
