Step-by-step explanation:
QU (2,3( (1,-2)
3--2/2-1 = 5/1
Slope of qu = 5
(-1,4)(-3,0)
0-4/-3--1= -4/-2 = 2
rs = 2
Answer:
D
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here (h, k ) = (3, - 2 ) , then
y = a(x - 3)² - 2
to find a substitute the point (4, 3 ) into the equation
3 = a(4 - 3)² - 2 ( add 2 to both sides )
5 = a × 1² = a
the coefficient of the squared expression is 5

Answer:
The answer is D: The inequality symbol in the alternative hypothesis points away from the critical region.
Step-by-step explanation:
We usually have a one-tailed and two-tailed tests. Examples of a one-tailed test are the left-tailed and the right tailed test. These tests are referred to as one-tailed tests because the critical region or rejection region is located in only one tail. The critical region of a left or right tailed test is that region that correlate with the rejection region and is usually located in extreme left or right tail. Furthermore, tails in a distribution are usually the extreme critical regions also known as the rejection regions which are bound by critical values. However there is nothing that suggests the statement in Option D when talking about tails in a distribution.
