Answer:
<em>The percentage of nights does it take employees less than 3 hours to clean the largest building </em>
<em> P( x < 3) = 2.28 hours</em>
<em>Step-by-step explanation:</em>
<u><em>Step(i):-</em></u>
<em>Given mean of the Population = 3.8 hours</em>
<em>Given Standard deviation of the Population = 0.4 hours</em>
Let 'X' be the random variable in Normal distribution
Let 'X' = 3 hours
<u><em>Step(ii):-</em></u>
<em>The probability that nights does it take employees less than 3 hours to clean the largest building</em>
P( x < 3) = P(Z < -2)
= 0.5 -A(-2)
= 0.5 - A(2)
= 0.5 - 0.4772
= 0.0228
<em>The probability that nights does it take employees less than 3 hours to clean the largest building</em>
<em>P( x < 3) = 0.0228</em>
<em><u>Conclusion:-</u></em>
<em>The percentage of nights does it take employees less than 3 hours to clean the largest building </em>
<em> P( x < 3) = 2.28 hours </em>
Answer:
$1.30
Step-by-step explanation:
divide the cost by 6 and you get 1.3 so 1 battery=1.30
Answer:
132
Step-by-step explanation:
Alternate angles are equal. Therefore, A = B.
<u>Find x</u>
5x - 18 = 3x +42
2x = 60
x = 30
<u>Substitute x in angle A</u>
5(30) - 18 = 132

Answer:
Step-by-step explanation:
Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."
So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.
w = 112 +8t
176 = 112 + 8t
64 = 8t . . . . . . . subtract 112
8 = t . . . . . . . . . divide by 8
The input for an output of 176 is 8.
__
Ordered pairs are always written as ...
(input, output)
So, (4, 144) means the output is 144 for an input of 4.
X=12/11 for the first one
