Answer: It would take 4 hours
Step-by-step explanation:
20/2=10 160/2=80 16/2=8
80/2=40 8/2=4 so 4 hours :)
Answer:
hours worked at job, number of siblings are examples of discrete random variable.
Step-by-step explanation:
Discrete random variable has values that can be counted. It has finite data that does not change continuously.
Hours worked at a job can be counted at the end of the day.
The weight of a child keeps changing continuously therefore it is not a discrete random variable.
Number of siblings can be counted.
The length of a fish can keep changing day by day therefore it is not a discrete random variable.

Answer: a is 7 b is 4
Step-by-step explanation: to get an equation with no solution the equation has to be the same so if a is 7 and b is 4 this will show no solution
Hi there!
We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
It would be a direct variation.
