4 0

Answer:

Step-by-step explanation:

The null and alternative hypothesis that would seek to challenge this belief would be

Null hypothesis: u = 0.75

Alternative hypothesis: u =/ 0.75

The type of test to be used would be a one sample z test where one sample is drawn from the population and the mean engagement of students who become knowledgeable in the material is measured and tested in an experiment against the null hypothesis.

DIA [1.3K]

Answer:

1 : 30

Step-by-step explanation:

300mm:9m​

We need to change the meters to mm

1 meter is 1000 mm

so 9 m is 9000 mm

300mm:9000mm

Divide both sides by 300

​300mm/300 : 9000/300

Graph y = x2 + 2. Identify the vertex of the graph. Tell whether it is a minimum or maximum. (0, 2); maximum (0, 2); minimum (2,
miskamm [114]

Answer:

(0,2); minimum

Step-by-step explanation:

Given:

The function is, y=x^{2}+2

The given function represent a parabola and can be expressed in vertex form as:

y=(x-0)^{2}+2

The vertex form of a parabola is y=(x-h)^{2}+k, where, (h,k) is the vertex.

So, the vertex is (0,2).

In order to graph the given parabola, we find some points on it.

Let x=-2,y=(-2)^{2}+2=4+2=6

x=-1,y=(-1)^{2}+2=1+2=3

x=0,y=(0)^{2}+2=0+2=2

x=2,y=(2)^{2}+2=4+2=6

x=1,y=(1)^{2}+2=1+2=3

So, the points are (-2,6),(-1,3),(0,2),(1,3),(2,6).

Mark these points on the graph and join them using a smooth curve.

The graph is shown below.

From the graph, we conclude that at the vertex (0,2), it is minimum.
