Answer:
Null hypothesis: The favorite sport of 53% of adults in the country is professional football ( with revenue of about $13 billion per year)
Alternate hypothesis: The adults in the country whose favorite sport is not professional football (with revenue of about $13 billion per year) is less than 53%
Step-by-step explanation:
The given claim is that the favorite sport of 53% of adults in the country is professional football (with revenue of about $13 per year) which is the null hypothesis. This means that the favorite sport of the remaining 47%(less than 53%) of adults in the country is not professional football (with revenue of about $13 billion per year) which is the alternate hypothesis
400 = 45x + 30x
400 = 75x
5.333 = x
Lets test
45mph for 5.333 hours = 240 miles
30mph for 5.333 hours = 160 miles
240 + 160 = 400 miles apart.
Answer:
Length = 20 inches
Area = 300 inches
Step-by-step explanation:
<em><u>TO FIND THE LENGTH</u></em>
Pythagorean Theorem: 15 squared + x squared = 25 squared
= 225 + x squared = 625
- 225 - 225
= x squared = 400
find square root
= x = 20 inches
x = 20 inches
Length = 20 inches
<u><em>TO FIND THE AREA</em></u>
length x width
length = 20 inches
width = 15 inches
20 x 15 = 300
Area = 300 inches
Answer:
The domain is the input.
Step-by-step explanation:
The domain is the input, the independent value—it's what goes into a function. The range or y-value is the output and the dependent value is the outcome.
