Emi computes the mean and variance for the population data set 87, 46, 90, 78, and 89. She finds the mean is 78. Her steps for finding the variance are shown below. (87–78) +(46–78) + (90-78) +(78–78) +(89-79) 5 (9)2-(32)²+(12)? + (0)+(11)? 5 81-1,024+144+0+121 5 -678 5 =-135.6 What is the first error she made in computing the variance?

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
