Answer:
The correct is the little (B) 0.76
We are given coordinates of the triangle: A(2,2), B(7,1) and C(8,-4).
We need to rotated 90° counterclockwise about the origin.
In order to find the new coordinates of rotatation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
A(2,2) --> A'(-2,2)
B(7,1) --> B'(-1,7)
C(8,-4) --> C'(4,8)
It is B. the differences are added together
Answer:
The mean amount of cereal in a box must be 23.42 ounces.
Step-by-step explanation:
Let <em>X</em> = amount of cereal in a box.
It is provided that <em>X</em> follows a normal distribution with mean <em>μ</em> and standard deviation <em>σ</em> = 0.25.
If 99% of the boxes contain 24 ounces or more of cereals then the probability statement is:
Use the <em>z</em> table to determine the <em>z-</em>value.
The value of <em>z</em> is -2.33.
Determine the value of <em>μ</em> as follows:
Thus, the mean amount of cereal in a box must be 23.42 ounces.
