7 0

Answer:

The average defective rate = .057

Step-by-step explanation:

Given -

Sample size n = 100

Day - 1 2 3 4 5 6 7 8 9 10

Defectives - 7 6 6 9 5 6 0 8 9 1

The average defective rate is the no of defective in each day for past ten days

The average defective rate = $\frac{\sum no\; of \; effective \; in\; each\; day}{no\; of \; day \times n}$

= $\frac{7 + 6 + 6 + 9 + 5 + 6 + 0 + 8 + 9 + 1}{10\times 100}$

= $\frac{57}{1000}$

= .057

I really am confused on how to write a proof.

kvasek [131]

Since ABCD is a parallelogram, the opposite sides will be parallel and equal,

$\begin{gathered} AB=CD \\ BC=AD \end{gathered}$

Consider that AC acts as a transversal to the parallel lines AB and CD, so we can write,

$\begin{gathered} \angle CAD=\angle ACB\text{ (Alternate Interior Angles)} \\ BC=AD\text{ (Opposite sides of parallelogram)} \\ \angle ADB=\angle CBD\text{ (Alternate Interior Angles)} \end{gathered}$

So by the ASA criteria, the triangle AED is congruent to the triangle CEB,

Then the corresponding parts of the triangles will be equal,

$\begin{gathered} AE=CE \\ BE=DE \end{gathered}$

Hence Proved.

The segments shown below could form a triangle ac=9. cb=8. ba=17

krek1111 [17]

The lengths of sides of a triangle have to satisfy the triangle inequality, which states that the sum of the two shorter sides must exceed the length of the third side.

Here 9+8=17 (not greater), so these segments do not form a triangle.
