Answer: A company has 440000 as revenue.
Step-by-step explanation:
Total revenue a company earned = 800000
Variable costs = 60% of revenue
So , variable costs becomes

Now, company lost = 40000
So, remaining revenue becomes

So, a company has 440000 as revenue.
If he saves $ 8 each week...and his mom is giving him 0.25 for each dollar, then he will have (8 + 0.25(8)) = 8 + 2 = $ 10 per week
10w = 100.....with w being the number of weeks
w = 100/10
w = 10...so he will have it in 10 weeks <==
Step-by-step explanation:
In statistics, the quartile is a measurement of the spread of values within a dataset above and below the mean via a division of the distribution into four defined intervals. A quartile partitions the data at three points within the distribution.
- 25% of the data lies below the lower or first quartile, denoted as
.
- 50% of the data lies below the median or second quartile, denoted as
.
- 75% of the data lies below the upper or third quartile, denoted as
.
Thus, logically, we know that the remaining 25% of the data lies above the third quartile.
As shown in the figure below, the score that defines the first quartile of the defined normal distribution is the same as the score that, when evaluated in the cumulative density function,
, gives 25% of the area under the bell curve.
To find this z-score, we can use the help of the NORM.INV function in Microsoft Excel, which obtains the inverse of the normal cumulative distribution and the syntax, type into a cell, is as follows:

which gives you the value 149.77 (2 s.f.).
This means that 25% of the values of cholesterol levels lie below 149.77.
