Answer:
Step-by-step explanation:
We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.
i.e. the function will become
.
Now, the given function :
Then , after reflection across y axis the new function will become:
Answer:
The translation statement is given by:
After the translation, the coordinates of vertex A is (-2,6).
Step-by-step explanation:
Given :
Vertices of a triangle ABC are:
A(−3, 4), B(4, −2), C(8, 3)
The triangle is translated 2 units up and 1 unit right.
To find the co-ordinates of point A after translation.
Translation rules.
For shift of units up, the translation is given as:
For shift of units right, the translation is given as:
So, it says the triangles is translated 2 units up and 1 unit right.
The translation statement is given by:
So, co-ordinates of point A after translation is given by :
After the translation, the coordinates of vertex A is (-2,6).
Answer:
And using the z score given by:
Where:
If we find the z score for we got:
So we want to find this probability:
And using the complement rule and the normal standard distribution and excel we got:
Step-by-step explanation:
For this case we have the proportion of interest given . And we have a sample size selected n = 474
The distribution of is given by:
We want to find this probability:
And using the z score given by:
Where:
If we find the z score for we got:
So we want to find this probability:
And using the complement rule and the normal standard distribution and excel we got:
