The variance for the data is 17,507. 5.
Given
The weekly salaries of a sample of employees at the local bank are given in the table below.
Employee Weekly Salary Anja $245 Raz $300 Natalie $325 Mic $465 Paul $100.
<h3>Variance</h3>
Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.
The mean value of the salaries of employees is;
![\rm Mean= \dfrac{245+300+325+465+100}{5}\\\\Mean=287](https://tex.z-dn.net/?f=%5Crm%20Mean%3D%20%5Cdfrac%7B245%2B300%2B325%2B465%2B100%7D%7B5%7D%5C%5C%5C%5CMean%3D287)
The variance is given by;
![\rm Variance=\sqrt{\dfrac{(245-287)^2 +(300-287)^2 +(325-287)^2 +(465-287)^2 +(100-287)^2}{5-2}} \\\\Variance = 132.316}\\\\On \ Squaring \ both \ the \ sides\\\\Variance^2=17,507. 5](https://tex.z-dn.net/?f=%5Crm%20%20Variance%3D%5Csqrt%7B%5Cdfrac%7B%28245-287%29%5E2%20%2B%28300-287%29%5E2%20%2B%28325-287%29%5E2%20%2B%28465-287%29%5E2%20%2B%28100-287%29%5E2%7D%7B5-2%7D%7D%20%5C%5C%5C%5CVariance%20%3D%20132.316%7D%5C%5C%5C%5COn%20%5C%20Squaring%20%5C%20both%20%5C%20the%20%5C%20sides%5C%5C%5C%5CVariance%5E2%3D17%2C507.%205)
Hence, the variance for the data is 17,507. 5.

Answer:
whhhhhh
Step-by-step explanation:
it is number 2 because i took the test
The equation you can use to solve the problem is;
50/30 = 300/x
Next Cross Multiply
50x = 9000
x = 9000/50
x = 180
The building's shadow is 180 feet tall
