you have:
1.) -8x-16 --->>>
Factor out a -8 -->>
-8(x+2)
2.)9d+15db --->
Factor out 3d -->
3d(3+5b)
3.) 2a-9ax-->>
Factor out -a -->
-1a(9x-2)
Thus, your answer.
Answer:
Step-by-step explanation:
Use the intercept method of graphing a straight line:
Let x = 0. We get y = 1. This is the y-intercept (0, 1).
Let y = 0. We get x = 6/11. This is the x-intercept (6/11, 0).
Plot both points and then draw a straight line through them.
100% - 11
X% - 3
-------------
X= (100*3)/11 %
X= 27,272727...%
Solution -
A student who was skeptical about this value decided to conduct a survey by randomly sampling 36 students. On average, the sampled students slept 6.6 hours per night.
The sample mean is the average of the 36 sampled students, which is 6.6 hours. So 6.6 represents the <u><em>sample mean.</em></u>
College newspaper stated that college students get an average of 7 hrs of sleep each night.
The claimed population mean is the stated average from the newspaper article, which is 7 hrs. So 7 represents the <u><em>claimed population mean.</em></u>
