Tell whether the ratios form a proportion. 6. 8/50, 4/10

A $0.18-\mu \mathrm{m}$ fabrication process is specified to have $t_{o x}=4 \mathrm{nm}, \mu_{n}=450 \mathrm{cm}^{2} / \mathrm{V} \cdot \mathrm{s},$ and $V_{t}=0.5 \mathrm{V}.$ Find the value of the process transconductance parameter $k_{n}^{\prime}.$ For a MOSFET with minimum length fabricated in this process, find the required value of W so that the device exhibits a channel resistance $r_{D S}$ of $1 \mathrm{k} \Omega$ at $v_{G S}=1 \mathrm{V}.$

Here are three situations in which consumers might need some protection. A motorist asks for a tow rope 'strong enough for my trailer'. It breaks the first time he tries to use it. Do you think the consumer needs some legal protection in these cases? For each example. identify which part of UK consumer protection laws have broken by the business selling the goods.

Write and solve a proportion to answer the question. 12. 14 is what percent of 56?

Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a lighthouse beacon. Pulsar PSR 1937 + 21 is an example; it rotates once every 1.557 806 448 872 75 + 3 ms, where the trailing $\pm3$ indicates the uncertainty in the last decimal place (it does not mean $\pm3$ ms).

How many rotations does PSR 1937 + 21 make in 7.00 days?

The table below shows the cost to send an overnight package using United Parcel Service.

Does the table define a function?

Let ƒ(x) be the function that gives the cost, in cents, to mail a first-class package that weighs x ounces. In August of 2009, the cost was $1.22 for a package that weighed up to 1 ounce, plus 17 cents for each additional ounce or portion thereof (up to 13 ounces). (Source: United States Postal Service.) Sketch a graph of ƒ(x).

Write and solve a proportion to answer the question. 16. 110% of 90 is what number?

Tell whether the ratios form a proportion. 10. 18/27, 33/44

Describe the test statistic for the runs test when the sample sizes $n_1$ and $n_2$ are less than or equal to 20 and when either $n_1$ or $n_2$ is greater than 20.

Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a lighthouse beacon. Pulsar PSR $1937+21$ is an example; it rotates once every $1.55780644887275 \pm 3$ $\mathrm{ms}$, where the trailing $\pm 3$ indicates the uncertainty in the last decimal place (it does not mean $\pm 3 \mathrm{~ms}$ ). what is the associated uncertainty?

B. The branches and dead leaves crackled under her feet.

C. She imagined being an explorer in the 1600s, before there were trails and markers to guide the way.
