Marc saved $2,533 in January than in December.
Step by Step calculation.
Given the details below :
Salary In December =$3,650
In January, Increased by 12%
Marc saves 30% of $3,650 in December
New salary can then be calculated as :
= Initial salary * % increase / 100 + Initial salary
= 3,650 * 12 / 100 + 3,650
= 3,650 * 0.12 + 3,650
= 4,088
The difference will now be
= 4,088 - 3650
= $438
Since Marc saves in December 30% of $3,650
= 30% of $3,650
= $1,095
Saves in January
= 1,095 + 438
= $2,533

Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
If you’re looking for the cost it would be, it would be $1,575
Using sampling concepts, one sample of 5 high schools in the city of Chicago is given by:
Englewood Stem, Hyde Park, Lake View, Marshall, Noble - UIC.
<h3>What is the missing information?</h3>
The problem is incomplete, but researching it on a search engine, it gives us a list of 15 high schools in Chicago, and asks us to take a sample of 5.
<h3>What is population and sample?</h3>
- Population: Collection or set of individuals or objects or events whose properties will be studied.
- Sample: The sample is a subset of the population, and a well chosen sample, that is, a representative sample will contain most of the information about the population parameter. A representative sample means that all groups of the population are inserted into the sample.
Hence, from the concepts of sample and populations, the sample of 5 means that we have to select 5 schools from the 15 listed, hence they are:
Englewood Stem, Hyde Park, Lake View, Marshall, Noble - UIC.
