Let's look at an example:
2.24 x 21.6
![2.24\\ 21.6\\ ______](https://tex.z-dn.net/?f=2.24%5C%5C%2021.6%5C%5C%20______)
Do normal multiplication and get
48384 This is not correct, until we put the decimals in. To know how to do this, count the number of decimal spaces from the factors. In 2.24, there are 2, because .24. In 21.6 there are 1 because of .6. This mean three places, so 48384 becomes
48.384

Answer:
![g(15)=93.8\%](https://tex.z-dn.net/?f=g%2815%29%3D93.8%5C%25)
see the explanation
Step-by-step explanation:
Let
x ----> the number of years since 2008,
g(x) ----> the percent of people 25 years and older who have completed at least high school
we know that
![g(x)=0.008x^2+0.42x+87.5](https://tex.z-dn.net/?f=g%28x%29%3D0.008x%5E2%2B0.42x%2B87.5)
so
For x=15 years since 2008
substitute
![g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%](https://tex.z-dn.net/?f=g%2815%29%3D0.008%2815%29%5E2%2B0.42%2815%29%2B87.5%3D93.8%5C%25)
That means
In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%
Answer:
Step-by-step explanation:
94
Mean = add all the numbers up and divide by how many numbers you added
So add (x +120 + 112 + 130 + 128 + 124 ) divided by 6 =118
x is the score you are looking for and 118 is the average he wants
so (x + 614 ) divided by 6 =118
now multiply both sides by 6
x + 614 = 118 times 6
x + 614 = 708
subtract 614 from both sides
x = 94
