Step-by-step explanation:
Given :
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.
To Find :
How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.
Solution :
Mass of copper in 50 gm alloy =
.
Mass of copper in 78 gm alloy =
.
Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.
Percentage of copper in resulting mixture :

Hence, this is the required solution.
Using it's concept, it is found that there is a 0.64 = 64% probability that neither flight is delayed.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 2 flights, each with a 0.8 probability of being on time. The flights are independent, hence the probability that both are on time is given by:
p = 0.8 x 0.8 = 0.64.

This is the formula for computing the required rate of return in a market: E(R)<span> = Rf + ß( R<span>market </span>- R<span>f </span>). This is called as the Capital Asset Pricing Model (CAPM). The E(R) represents the required rate of return; the Rf is the risk-free rate; the </span>ß is the beta coefficient (which we are looking for); and the Rmarket is the rate of return on the market. Substituting the values to this formula, you can come up with the beta coefficient of 1.4.
