Answer:
B) Mode doesn't change.
Step-by-step explanation:
Given:
A set of data with 16 being added to the set.
The mode of a given set of data is the data that is repeated the most number of times.
Here, 19 is repeated 3 times, so the mode is 19.
Now, if a number other than that of 19 being added, doesn't affect the mode of the data set as 19 will still be 3 times and adding 16 will not increase its number in the set.
So, the correct option is B.
The equation 0 = -2x2 5x - 3 was the quadratic formula that Zacharias used. However, he started substituting as:
Quadratic formula as x = ; substitution as x
The errors he made: he mistakenly used the negative (-) and postive (+)
* -5 should have been 5
* 52 should have been -52
* both the numerator and the denominator should have been -2 instead of 2
Answer:
D. 4x-3
Step-by-step explanation:
First you subtract the 7x and 3x to get 4x.
Then you subtract the -5 and the -2 to get -3
Therfore, your answer is D
