Answer:
C. A'(3,4) B'(-1,3) C'(-1,-1)
Step-by-step explanation:
180° rotations in coordinate planes are fairly simple.(You have to do this with each point)The formula would be (x,y) --> (-x,-y). If the value is negative, it becomes positive, and vise versa.
The 4C matrix is obtained when all elements of matrix C are multiplied by 4. It <span>has all the same elements as C, only multiplied by 4.
Let's analyze all matrices
A. Not all elements of A can be divided by 4 (3 can not be divided by 4, the solution is not a whole number).
B. All elements of matrix B can be divided by 4, which means that B is a $C matrix (there is a matrix C which multiplied by 4 gives the matrix B).
C. Not all elements of C can be divided by 4.
D. Not all elements of D can be divided by 4.
Solution: B

Step-by-step explanation:
<u>The distance is the difference in top and bottom positions:</u>
- 4 - (-9) = 4 + 9 = 13 inches
Answer:
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
The confidence interval for the mean is given by the following formula:
(1)
Since the Confidence is 0.95 or 95%, the value of
and
, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.025,0,1)".And we see that
Now we have everything in order to replace into formula (1):
Answer:
Starts at 13122, and divides by 3
Step-by-step explanation:
4374 x 3 = 13122
