Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15
The ratios are not equivalent because when they are reduced, they do not equal the same thing.

Consider the quadratic function y = 0.3 (x-4)2 - 2.5 <br> Determine the axis of symmetry, x =
fomenos

Answer:

x=4

Step-by-step explanation:

We have the quadratic function:

\displaystyle y=0.3(x-4)^2-2.5

And we want to determine its axis of symmetry.

Notice that this is in vertex form:

y=a(x-h)^2+k

Where (<em>h, k</em>) is the vertex of the parabola.

From our function, we can see that <em>h</em> = 4 and <em>k</em> = -2.5. Hence, our vertex is the point (4, -2.5).

The axis of symmetry is equivalent to the <em>x-</em>coordinate of the vertex.

The <em>x-</em>coordinate of the vertex is 4.

Therefore, the axis of symmetry is <em>x</em> = 4.

A mechanical engineer wishes to compare strength properties of steel beams with similar beams made with a particular alloy. The
Annette [7]

Answer:

50

Step-by-step explanation:

Level of significance, a = 0.01

Type II error probability, b =0.05

From the z-table:

the critical value at 1% level of significance, Zα = Z0.01 = 2.33

the critical value at 5% probability, Zβ = Z0.05 = 1.645

The critical value of z can be obtained from the standard normal table using the desired level of significance and the tail of test.  

The critical value tells the number of standards deviations away is the result from the mean.

Probability of type I error denoted by  a

Probability of type II error denoted by b.

Type I error is to falsely infer the existence of something that is not there, while a type II error is to falsely infer the absence of something that is.

From the given information,

a=0.01, b=0.05, o1 = o2 =0.05, Dο = 0, D' = 0.04

The sample size is calculated as,

n = ( o^2 + o2^2) * (Za +Zb)^2 /( (D' - D0)^2)

= (0.05^2 +0.05^2)*(2.33 + 1.645)^2 / (0.04 - 0)^2

= 49.38

which is 50 [Rounded to next integer]
