The price of the Xbox One after tax is $265
<h3><u>Solution:</u></h3>The price of a Xbox one is $250
The tax on Xbox one is 6%
Now, the tax of 6% on 250 is calculated as follows:-
So, the tax on Xbox one is $15
The total price of box including tax can be calculated by adding price of box and tax on box
<em>Total price of Xbox after tax = actual price of the Xbox One + Tax on the Xbox One </em>
= $250 + $15
= $265
Hence, the price of the Xbox One after tax is $265
Answer: Growth factor will be 0.15 and percent increase will be 15%.
Step-by-step explanation:
Since we have given that
the exponential growth function
1) We need to find the growth factor :
As we know the formula for "Compound Interest ":
If we compare the formula with our given equation, we get
So, the growth factor is at the rate of 0.15.
2) Percent increase will be
Hence, growth factor will be 0.15 and percent increase will be 15%.
Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.
Answer:
The probability value is almost equal to 0. Implying that the proportion of people dying in that particular interval if deaths occurred randomly throughout the year is unusual.
Step-by-step explanation:
The random variable <em>X</em> can be defined as the number of decedents who died in the three-month period following their birthdays.
A random sample of 747 obituaries published recently in Salt Lake City newspapers revealed that 344 (or 46%) of the decedents died in the three-month period following their birthdays (123).
The probability (p) of anyone dying in any quarter if people die randomly during the year is simply 0.25.
The random variable <em>X</em> follows a Binomial distribution with parameters n = 747 and p = 0.25.
But the sample selected is too large and the probability of success is small.
So a Normal approximation to binomial can be applied to approximate the distribution of <em>p</em> if the following conditions are satisfied:
Check the conditions as follows:
Thus, a Normal approximation to binomial can be applied.
So, .
Compute the probability that 46% or more would die in that particular interval if deaths occurred randomly throughout the year as follows:
*Use a <em>z</em> table for the probability.
The probability value is almost equal to 0. This probability is very low indicating that the proportion of people dying in that particular interval if deaths occurred randomly throughout the year is unusual.
