Answer:
Step-by-step explanation:
4) x² - 14x + 48
We would find two numbers such that their sum or difference is -14x and their product is 48x².
The two numbers are - 6x and - 8x. Therefore,
x² - 6x - 8x + 48
x(x - 6) - 8(x - 6)
(x - 8)(x - 6)
5) 2x² + 21x - 11
We would find two numbers such that their sum or difference is 21x and their product is - 22x².
The two numbers are 22x and - x. Therefore,
2x² + 22x - x - 11
2x(x + 11) - 1(x + 11)
(2x - 1)(x + 11)
6) 5a² - 125
5 is a common factor. So we would factorize 5. It becomes
5(a² - 25)
Simplifying further, it becomes
5(a + 5)(a - 5)
To convert a percent to decimal, move the decimal place two places to the left. You get 0.091
The probability that a student uses the Internet, given that he or she is in eighth grade is 8/13 or 0.66
<u>Step-by-step explanation:</u>
<u>From the table shown:</u>
- The students in the eighth grade = 13
- The eighth grade students using internet = 8
P(student uses the Internet in eighth grade) = P(eighth grade students using internet) / P(total students in the eighth grade)
⇒ 8/13
⇒ 0.66

Step-by-step explanation:
What is 15.41 rounded to the nearest hundredth?
Rounding to the Nearest Hundredth. Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.843 to the nearest hundredth would give 0.84.
