Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~
Generally what I like to do, to solve questions like this is to substitute the given answers into the equation to solve this faster...
Equation: x^2 + 10x + 12 = 36
A.) (-12)^2 + 10(-12) + 12 = 36
144 - 120 + 12 = 36
24 + 12 = 36
36 = 36
(2)^2 + 10(2) + 12 = 36
4 + 20 + 12 = 36
24 + 12 = 36
36 = 36
Since we found the answer with the first try, we already know the correct answer is A.
So...
The Correct answer is: A.) x=-12 or x=2
Answer: A. y=5/6x-3
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
I'm almost 100% sure this is right.
Answer:
No
Step-by-step explanation:
Two samples are matched pairs if the samples are dependent sample. All the attributes or characteristics of these samples are the same except the one thing which we need to study or experiment.
The given samples are independent samples. So, these these two sample are not matched pair samples. Such samples cannot be used to perform the paired sample t test. For this test the samples must always be dependent.
Example of dependent or matched pairs samples under given scenario would be like:
The instructor teaches a section in one semester using the computer homework system and in the next semester he teaches the same section using the paper and pencil homework system.
Usually the pairs in matched pairs are the same people just at different time, as stated in the previous example.
First lets take away the negative sign for now
Now lets separate the number into its two components which are 11 and 0.16
Now lets rewrite it to 16/100
Next we want to find the greatest common factor between 16 and 100 which is 4 since 4 * 4 equals 16 and 4 * 25 equals 100 so its 4.
Now lets divide 16 and 100 by the greatest common factor so its sixteen divided by 4 over 100 divided by 4
Next we simplify all together which is 4/25
You remember that number 11 we had earlier, well we are going to go grab him back and add him to the fraction and make it 11 4/25 but... remember that negative sign, I said for now, right, so lets put him back on the spotlight.
Answer: -11 4/25
Answer:
Top right answer
Step-by-step explanation:
He added the -x to 4x when he should have subtracted.
