1. To increase an amount by 45% multiply by

2. To decrease an amount by 30% multiply by

1. 0.55

2. Though a, a 30% increase, that's a multiplier of 1.3, a 30% decrease is a multiplier by, of . 7. And so, we just multiply 100 by each one of those multipliers. So, 100*1.3*.

Step-by-step explanation:

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
