Describe how the shape moves from:
1 answer:
Answer:
1. Frame 1 to Frame 2 - Vertical downward translation
2. Frame 2 to Frame 3 - counterclockwise rotation
3. Frame 3 to Frame 4 - Vertical upward translation
Step-by-step explanation:
The movement of the shapes from one frame to the other can be described by solid transformations. These are procedures required to change the orientation or size of a given shape. They include: rotation, translation, dilation and reflection.
1. When the shape in frame 1 is translated vertically downwards, it would produce the shape in frame 2.
2. Rotating the shape in frame 2 by counterclockwise would move it to the shape in frame 3.
3. Vertical upward dilation would move the shape in frame 3 to that in frame 4.

The correct option is B
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
The sample size is
The sample mean is
Generally
The null hypothesis is
The alternative hypothesis is
Given that the null hypothesis is true then the distribution of sample means , from a sample size of 36 is mathematically represented as
=>
According to the Central Limit Theorem the test stated in the question is approximately normally distributed if the sample size is sufficiently large so given that the sample size is large n = 36
Then the test is normally distributed and hence the standard deviation is 15
Generally the standard error of mean is mathematically represented as
=>
=>
Generally the approximate probability of observing a sample mean of 105.1 or more is mathematically represented as
=>
