Answer:
y 》 2
y > -x + 3
Step-by-step explanation:
Equation of the bold line:
m = (-3/3) = -1
y = -x + 3
Shaded region is below y=2 (dotted)
So, it's defined by y < 2
Also, it's below the bold line
y 《 - x + 3
Everything outside these is not shaded:
y 》2
and y > -x + 3
Answer:
B. 
Step-by-step explanation:
The given quadratic trinomial is;
Comparing this to 
, we have a=5,b=17,c=6.
Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;
We factor by grouping;
Factor further
The correct answer is B.
Answer:
4/10
Step-by-step explanation:
Answer:
t distribution behaves like standard normal distribution as the number of freedom increases.
Step-by-step explanation:
The question is missing. I will give a general information on t distribution.
t-distribution is used instead of normal distribution when the <em>sample size is small (usually smaller than 30) </em>or <em>population standard deviation is unknown</em>.
Degrees of freedom is the number of values in a sample that are free to vary. As the number of degrees of freedom for a t-distribution increases, the distribution looks more like normal distribution and follows the same characteristics.
