Answer:
Step-by-step explanation:
We can find out by using synthetic division and the fact that x - 9 Might be a 0. If x = 9 is a 0 of that polynomial, then we will get no remainder when we divide the polynomial by 9:
9 | 1 -5 7
____________
First thing to do is bring down the 1 and multiply it by the 9 and put that product up under the -5:
9 | 1 -5 7
______<u>9</u>____
1
Now add down the column to get:
9 | 1 -5 7
_____<u>9</u>____
1 4
Now multiply 4 by 9 and put that product up under the 7:
9 | 1 -5 7
______9__36
1 4
Now add to see what the remainder is:
9 | 1 -5 7
_______9_36
1 4 R43
we have a remainder of 43. Since it is not a 0, then the polynomial is not evenly divisible by x - 9.
So the answer is No.
" the quotient " means divide
9 more then the quotient of -36 and -4...
(-36/-4) + 9 =
9 + 9 =
18
Answer:
I am going with B
Step-by-step explanation:
Okay so there are 3 columns so I'm 100% you'll do the equation times 3. The equation will be addition because there is no multiplication sign there. its 54+5*3 the only thing that matches that is B

Answer:
<h2>69.5</h2>
Step-by-step explanation:
Given the confidence interval of the heights of american heights given as (65.3,73.7);
Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7
Sample mean will be the average of both confidence interval . This is expressed mathematically as 

Hence, the sample mean is 69.5
