Explanation:
The term "variant" means "it changes" or "it moves location".
So "invariant" means it stays fixed in place.
The translation vector 
is the same as writing the rule 
. It says to shift every (x,y) point 1 unit to the right and 3 units up. The key to this is the "every". There isn't a point left out that the translation doesn't touch. No points stay fixed in place. <u>There are no invariant points</u>.
In contrast, if we were to do a dilation, then the invariant point is the center of the dilation. Everything either shrinks or enlarges with respect to this fixed center point. Another example would be a rotation where the center of rotation stays fixed. Unfortunately, translations do not have this property of having an invariant fixed point.
A line is 180° so if you are given 43°on part of line l
180-43=137
So x=137°
Answer:
Option A is right.
Step-by-step explanation:
Given that a new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 50 women over the age of 50 used the new cream for 6 months. Of those 50 women, 44 of them reported skin improvement(as judged by a dermatologist)
(Right tailed test)
Sample size = 50
Std error of proportion =
p difference=
Z statistic = p diff/std error = 6.928
p value <0.00001
Since p is less than alpha, reject null hypothesis.
A. We can reject the null hypothesis that p=0.4 and accept that p>0.4. That is, the cream can improve the skin of more than 40% of women over 50.
9/4 cups of flour is equal to 2 1/4 2/4 cups of flour is equal to 1/2 SO 16/4 cup flour is equal to 4 Which is 7/4 cups more than 2 1/4 7/4 cups is 1 3/4 cups (1/2 a cups less than 2 1/4) Which means he needs 1 3/4 cups of walnuts.
<span>Simplfied- 4 cups is 1/2 a cups short of double, since the flour is done is quarters, take the 1/4 cup away from the walnuts. </span>
<span>(times 1/2 by 1/2 you get 1/4 subtract it)</span>
