Answer:
The true statement about the results of the survey is:
- <u>48% of students preferred the seacoast</u>.
Step-by-step explanation:
To identify if the D option is right, you only must use a simple rule of three, where you use the total of the members surveyed in the club (150), and the number of members that preferred the seacoast (72), by the last the operation must confirm that this value (72) is equal to the 48% (how says in the D option). First, you must establish the rule of three:
- 150 = 100 (100% of surveyed really, but is easier to understand in this form)
- 72 = X
And operate:
- X= (72 * 100) / 150
- X = 48 (this means the 48%)
How you can see, <em>the value obtained in the simple rule of three is exactly </em><em>the percentage of the D option, for this reason, this is the true statement</em>.
Answer:
So I did this in the beginning of my seventh grade year.
Step-by-step explanation
center is natural numbers
then whole numbers
then integers
then rational numbers on the outside
does this help?
Start by taking out a common factor.
x^10
x^10(x^6 - 2x^5 - x^4 + 4x^3 - x^2 - 2x + 1) = 0
So far we know that D won't work.
x - 1 is a factor because putting 1 in for the xs in the expression inside the brackets gives 0 Now you need to do a division. I'm going to assume you can do that.
Using division, I get
x^5 - x^4 - 2x^3 + 2x^2 + x - 1 Now divide x - 1 into this mess again. You get
x^4 - 2x^2 + 1 which factors into
(x^2 - 1)(x^2 - 1) which factors into
(x - 1)(x + 1)(x - 1)(x + 1) = 0
The first two divisions add (x -1)(x - 1)
========================
So we have (x - 1) with a multiplicity of 4 and (x + 1) with a multiplicity of 2
or x = 1 with a multiplicity of 4 and x = -1 with a multiplicity of 2 and x = 0
with a multiplicity of 10
That's the answer.

Since there would be 20 people in total, I think the snacks would last 5 days.
