Answer:
45 feet
Step-by-step explanation:
Use ratios:
x = 540 inches
divide by 12 to get 45 feet
Answer:
Type I error
Step-by-step explanation:
Here, we are interested in knowing the type of error that stems from the hypotheses set up
in the question.
From the suggestion of the sample, we know that the food is actually safe but was wrongly labeled as being unsafe.
So in this case, the type of error committed is the type 1 error since the food is actually safe but there was a wrong suggestion of being generally unsafe by the sample
Using proportions, it is found that the two cities are 27.5 miles apart.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
From the given scale, we have that <u>each inch of distance represents 10 miles</u>. Hence the distance in miles for a distance of 2 and 3/4 miles = 2.75 miles is given by:
D = 10 x 2.75 = 27.5 miles.
Hence, the two cities are 27.5 miles apart.
