608
Step-by-step explanation:
12.8 × 1.5 is 19.2 so 19.2 × 5 is 96 dollars in overtime and then 12.8 × 40 is 512 so 512 + 96 is 608
Answer: The sample mean and sample standard deviation is 74.004 millimeters and 0.005 millimeters respectively.
Step-by-step explanation:
The given values : 74.001, 74.003, 74.015, 74.000, 74.005, 74.002, 74.007, and 74.000.
![\text{Mean =}\dfrac{\text{Sum of all values}}{\text{Number of values}}\\\\\Rightarrow\overline{x}=\dfrac{ 592.033}{8}=74.004125\approx74.004](https://tex.z-dn.net/?f=%5Ctext%7BMean%20%3D%7D%5Cdfrac%7B%5Ctext%7BSum%20of%20all%20values%7D%7D%7B%5Ctext%7BNumber%20of%20values%7D%7D%5C%5C%5C%5C%5CRightarrow%5Coverline%7Bx%7D%3D%5Cdfrac%7B%09592.033%7D%7B8%7D%3D74.004125%5Capprox74.004)
The sample standard deviation is given by :-
![\sigma=\sum\sqrt{\dfrac{(x-\overline{x})^2}{n}}\\\\\Rightarrow\ \sigma=\sqrt{\dfrac{0.000177}{8}}=0.00470372193056\approx0.005](https://tex.z-dn.net/?f=%5Csigma%3D%5Csum%5Csqrt%7B%5Cdfrac%7B%28x-%5Coverline%7Bx%7D%29%5E2%7D%7Bn%7D%7D%5C%5C%5C%5C%5CRightarrow%5C%20%5Csigma%3D%5Csqrt%7B%5Cdfrac%7B0.000177%7D%7B8%7D%7D%3D0.00470372193056%5Capprox0.005)
Hence, the sample mean and sample standard deviation is 74.004 millimeters and 0.005 millimeters respectively.
Answer: x =4
Mary is 8 and John is 4
Explanation:
John = x
Mary = 5x - 12 or 2x
Solve for x
5x - 12 = 2x
-12 = -3x
X=4
