Not sure what 14 is asking?

15 would be 16.

The square root of width squared plus length squared equals the diagonal.

So if you just change the order of the equation you can find the length.

Double check it by doing it both ways to see if your answer is right.

A certain process for manufacturing integrated circuits has been in use for a period of time, and it is known that 12% of the ci

enyata [817]

Answer:

(a) No the conclusion is not justified.

b. No

c. Two defective circuits in the sample

Step-by-step explanation:

Ans: (a) No the conclusion is not justified. What is important is the percentage population of defectives;

the sample proportion is only an approximation. The population proportion

for the new process may be more than or less than that of the old process. We can decide to pick two hundred samples and discover that the number of defects is greater than the previous process

(b)

.For the defectives, the population proportion for the new process may be 0.12 or more,

although the sample of defectives is just 11 out of 100

(c) Two defective circuits in the sample. This is because the probability of having two defects from the 100n samples is less than having 11 defects

1. Which graph represents a relation that is not a function?

Artemon [7]

The second one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).

In every function, you must have a single "y" value for each "x" in the domain.

__________

In order to see it better, you can trace a vertical line onto that graph.

If that line and the graph intersects in more than one point, then that graph doesn't represent a funcion.

Look into the attached picture and see. That vertical red line and the graph intersects in two distinct points. Therefore, it can't represent a function.

Any doubt? Please, comment below.

I hope it helps. :-)

How to simplify this expression

WITCHER [35]

$\frac{2x+4}{3x-3}( \frac{12x-12}{x+5})$
= $\frac{2(x+2)}{3(x-1)}( \frac{12(x-1)}{x+5})$
= $\frac{2(x+2)4}{x+5}$
= $\frac{8(x+2)}{x+5}$

--------------------------------------
$\frac{x^2-16}{2x-8}$ ÷ $\frac{x-4)^2}{8x-32}$
= $\frac{x^2-16}{2x-8}$ ( $\frac{8x-32}{x-4)^2}$ )
= $\frac{(x-4)^2}{2x-8}$ ( $\frac{8x-32}{x-4)^2}$ )
= $\frac{1}{2x-8}$ ( $\frac{8x-32}{1}$ )
= $\frac{8x-32}{2x-8}$
= $\frac{8(x-4)}{2(x-4)}$
= $\frac{4(x-4)}{1(x-4)}$
=4
