Explanation:
1/3 of 600 is 200. That represents the boys.
Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).
Answer:
Domain = All real numbers
Range = y ≥ 0
Step-by-step explanation:
As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers
Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it <em>can</em> still be 0) Since y can only be positive... we define the Range as y ≥ 0
Answer:
25 males and 8 females.
Step-by-step explanation:
If x is the number of males and y = number of females we have the system:
x + y = 33
x - y = 17 Adding:
2x = 50
x = 25
so y = 33 - 25 = 8.
Answer:
8/37
Step-by-step explanation:
First subtract 450 - 370.
450 - 370 = 80
Then put it into fraction form where the increase is the numerator and the cost from last year is the denominator.
80/370
Then, simply the fraction (if possible).
8/37
Divide 1515 by 3. That's the number of points per one text. Take 18001800 and divide it by 505 (the number of points per one text) and that is your answer. 35647 texts.
