To get the probability of two individual events both occurring,
you have to multiply the probabilities of their individual events occurring. Therefore
in this problem, the probability that a student selected at random will pass
both French 101 and French 102 is 0.683 (.75 x .91). The answer is already
rounded to three decimal places.
Answer:
Need a picture of the problem.
Step-by-step explanation:
The Principal is the amount you deposit at the start, so P= $500
The rate is 7%, as you will be earning 7% extra yearly in simple interest.
As a decimal, the rate is 0.07 - 7 PER CENT literally means per 100, so 7/100 is 0.07. However, when actually figuring out the simple interest, you have to add 1 to 0.07 because you are earning 7% ON TOP OF your original amount.
The time is 10, as you are leaving the money in the account for 10 years, and time is measured in the given unit
Now, let's plug in this information into the general formulas:
I=Prt
where I is the just the interest earned
I=500×0.07×10
I=$350
A=P(1+r/100×t)
where A is the total amount (original sum of money plus interest)
A=500(1+0.07×10)
A=$850
An equation is formed of two equal expressions. It will take for the radioactive element to decay from 960 grams to 295 grams in 25.54 minutes.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The radioactive decay of an element is given by the formula,
Given the half-life of the element is 15 minutes, therefore, we can write,
Now, the time it will take for 960 grams to decay to 295 grams is,
Hence, it will take for the radioactive element to decay from 960 grams to 295 grams in 25.54 minutes.
