The supermarket then realized they missed a brand. when the new brand was cooked, only 74% of its kernels popped. let b be the data set of percentages for all 11 packages, including the package where the least kernels popped. select the statements that are true. including the percentage for the package where the least kernels popped causes the spread of the data to decrease. the standard deviation of b is greater than the standard deviation of a. the interquartile range of a is the same as the interquartile range of b. the median of a is the same as the median of b. including the percentage for the package where the least kernels popped causes the center of the data to increase. the mean of a is the same as the mean of b.

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
