Step-by-step explanation:
The variance is the total of the squared distances of the given data from the mean.
This can be calculated through the equation,
σ² = summation of X² / N - μ²
where σ² is the variance X's are the data, N is the number of terms, and μ is the mean.
summation of X² = 100² + 100² + 120² + 120² + 180² = 81200
N = 5
μ = (100 + 100 + 120 + 120 + 180) / 5
μ = 124
Substituting these values to the equation for variance,
σ² = (81200/5) - 124² = 864
Thus, the variance is equal to 864.
Answer: 9,364cm
Step-by-step explanation: 1 meter = 100 centimeters so it’s 93.64(100) = 9,364
23 represents the wait time at the time the store opens.
The answer is 212 because you subtract 550-338 equaling 212
