Lilit [14]3 years ago

Answer:

c = - 2

Step-by-step explanation:

Since (z - 3) is a factor of p(z) then z = 3 is a root and p(3) = 0

p(3) = 3³ + 9c - 4(3) + 3 = 0, hence

27 + 9c - 12 + 3 = 0 ⇒ 9c = - 18 ⇒ c = - 2

Ari’s teacher says he may have his report grade based on either the mean or the median of his last six test scores.
stepan [7]
To find the mean you: <span>add up all the numbers, then divide by how many numbers there are.  So the mean for these numbers would be: 84%

To find the median: You put the numbers in order (From least to greatest), and then find the number exactly in the middle. Here it is an even amount of numbers. No problem, just add the two numbers in the middle and then divide by 2. The answer here is: 84%

Find the sum of 18 + (-15).<br><br> A. 3<br><br> B. -3<br><br> C. 33<br><br> D. -33
Delvig [45]

Answer: 3

Step-by-step explanation: To find the sum of these two numbers, remember that adding a negative is exactly the same thing as subtracting a positive. In other words, when we see 18 + (-15), we can change the problem so it's easier to understand and we will change in to 18 - 15.

Now, this is just basic subtraction.

18 - 15 = 3

Therefore, 18 + (-15) = 3
