X=-1
The axis of symmetry will be directly in the middle of the intercepts.
The first one because it’s (13(31)
Subtract 24 from both sides (-45t=-8) then divide both sides by -45 (t=0.177)
The answer is b cause none of x is the same number
<span>In statistics finding percentiles relates to the standard deviation and something called a z-score. For normally distributed data the z-score represents how many standard deviations above or below the mean that group is a part of. The z-score for normally distributed data for the 90th percentile is 1.28. The standard deviation is then multiplied by the z-score to find, in this case, the shotlrtest height needed to be in the 90th percentile of this population. In this case to be in the 90th percentile your height must be 60.27 inches.</span>
