Answer:
the probability that exactly 30 of the 500 calculators IS 0.0495
Explanation:
Given data:
number of calculators n = 500,
percentage of defected calculators p = 0.05
From Normal approximation method;
Therefore probability is
P(X= 30) = P(29.5< X< 30.5) ( from continuous correction)
![ =P[\frac{(29.5-25)}{4.87}] < \frac{(X-mean)}{s} < \frac{(30.5-25)}{4.87} =P(0.92](https://tex.z-dn.net/?f=%0A%3DP%5B%5Cfrac%7B%2829.5-25%29%7D%7B4.87%7D%5D%20%3C%20%5Cfrac%7B%28X-mean%29%7D%7Bs%7D%20%3C%20%5Cfrac%7B%2830.5-25%29%7D%7B4.87%7D%0A%3C%2Fp%3E%3Cp%3E%0A%3DP%280.92%3CZ%3C%201.13%29%0A)
=0.0495 (from standard table of Z )
The non-corrosive material is Copper
copper is made of because of the naturally protective film that is formed on top of its surface which consists of <span>cuprous oxide (Cu </span>2<span>0).
This protective film prevents the corrosive process that started whenever a metal is in touch with oxygen or other aqueous substances.</span>
Increases in government spending are not very effective in offsetting real shocks because they shift the aggregate demand.
<h2>Definition of Aggregate Demand</h2>
Aggregate demand is the value of all requests for all types of goods and services produced in a certain period. The demand value contained in this aggregate will be expressed in terms of the overall value used for these goods and services up to a more specific price level and at a certain time period.
Some things that include aggregate demand are all consumer goods, capital goods used for the production process, import-export activities, and state government spending programs. Each of these variables will be considered the same as long as they are traded at the same market value.
This aggregate demand can also be calculated over a long period of time, which is often referred to as GDP or Gross Domestic demand. If this GDP will describe the total value and also the goods produced, then aggregate demand will represent the desire for goods and services.
