A normal distribution has a mean of 22 and a standard deviation of 3. a. The mean of this distribution is ?
b. The mode of this distribution is ?
c. If the standard deviation is increased to 4 , will the curve become wider or taller ?

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

step-by-step explanation:

just plug in each number for x and see which ones work and don't

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.
