The thickness of a part is to have an upper specification of 0.925 and a lower specification of 0.870 mm. The average of the process is currently 0.917 with a standard deviation of 0.005. Determine the percentage of product above 0.90 mm.

Solution

Given u = 0.917 and s = 0.005

P(X > 0.9) = P(Z > (0.9 – u) / s)

= P(Z > (0.9 &#██████████; ██████) █ ████████████)

Assume cos(x) +5sin(x)= 23/5

and

6cos(x)+sin(x)=22/5

Find the exact numeric value of sec(x) and find the exact numeric value of tan(x).

Solution

cos(x) +5sin(x) = 23/5 ———— (1)

6cos(x)+sin(x) = 22/5 ————– (2)

6 * (1) – (2)==> 6cos(x) +30sin(x) – {6cos(x)+sin(x)} = 138/5 – 22/5

==> 29sinx = 116/5

1. Show the difference between Demand Pull Inflation and Cost push inflation.. give a specific example for each.

2.Explain why value of saving must equal to the total value of investment. S = I

Solution

The difference between these two types of inflation is found in their causes. Both have the same effects (increasing price level), but they are caused by different things.

Demand-pull inflation is caused by excess demand. When the people as a whole get more money they are able to pay more for goods and services (unless more goods and services are produced). Economists talk about more money \”chasing\” the same amount of goods and services. This causes shortages and prices rise.

Cost-push inflation is caused by disruptions in supply. These disruptions cause increases in the price of production. That leads to inflation. For example, a rise in the price of oil causes practically all production to become more expensive.

There is no technical way to determine for sure which kind of inflation is going on. Analysts must simply look around to try to see if the money supply is increasing or if there are supply shocks. Then they have to make informed guesses about why the inflation is happening.

Why Savings equals Investment:

Using the GDP equation to explain saving and investing:

Begin with our GDP equation for an open economy:

Y = C + I + G + NX

To simplify this idea, let’s look at a closed economy, where there are no imports or exports. This means that NX will equal 0 and will therefore drop out. This leaves us with:

Y = C + I + G

We can rearrange this equation to solve for investment (I) as a function of the other variables in the economy:

I = Y – C – G

This equation tells us that investment in the economy will be equal to the total amount produced (GDP = Y) minus consumption spending, and government purchases.

Now we can create a savings for the economy equation. The total amount of private savings (savings by the private sector meaning households and firms) is going to be equal to the amount produced (Y) plus transfer payments from the government (we will call this TR, and include things like unemploymen█, ██████████████ █████████████████ ████████ █████████████████) ███████████ ████████ █████████ ███████████ ████ ██████████████████████████ (███) ████ ██████████ (█)█
