Answer: it is invalid
Step-by-step explanation: it is invalid because the data table has 30 out of 100 people stating that they prefer to view movies in theater. This does not have the same ratio as 300 out of 400, and would only work had he said 300 out of 1000. Thus, he is incorrect in his inference.
Answer:
1.64
Step-by-step explanation:
To find whether or not the ratios are proportional, simplify. The first ratio is already simplified, so simplify the second one. to do this, find what factors 24 and 35 have in common.
Factors of 24: 1, 2, 3 ,4, 6, 8, 12, 24
Factors of 35: 1, 5, 7, 35
It looks like there are now common factors between 24 and 35. For the ratios to be proportional, they have to have the same value. If 24/35 can't be simplified to 4/7, the factors are not proportional.
So, to answer the question: No, the ratios are NOT proportions. I hope this helps and have a great rest of your day!
Answer:
5 units squared
Step-by-step explanation:
To find the area of a triangle, the formula is base * height/2
the base of this triangle is 2 while the height is 5
area = (2*5)/2
area = 5 units squared
