Answer:
Step-by-step explanation:
Domain is all the x's and range is all the y's. There's no reason why you couldn't pop any x into the given equation and calculate it and get a number out. So literally ANY x can be used and found on this graph. So the domain is all real numbers, one of the first two answers is going to be the right one. Now, the range is all the y's on the graph. The problem says that the parabola opens down, which means it has a highest point. There is no graph above that point. That's the point (-1, 16). So 16 is the highest y-value you can find on the graph. All the rest of the y's are smaller. The range is all the y's such that the y's are 16 and smaller...in math that's written {y | y <= 16} So the second answer is the right one.
If you use the common denominator of .5 for both sides of the ratio, you will arrive at 3:5 as a simplified form.
Answer:
1. option D
2. option A
Step-by-step explanation:
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.
The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
First, find the amount of time is taken to travel 1 mile :
time taken to travel 1 mile = 20/6 = 3 ⅓ mins
hence, time taken to travel 9 miles = 3 ⅓ x 9 = 30 mins
time taken to travel 10 miles = 3 ⅓ x 10 = 33 ⅓ mins
