Answer:
Ok so first you would have to turn them into improper fractions which is
3 
= 
and 4 
= 
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take and mutiply both numbers by 2 and get 
. Then mutiply both numbers in by 5 to get a common denominator.
=35 - 44 = -9 so your answer is 
Step-by-step explanation:
c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.
Answer:
a=-7.275*967
Step-by-step explanation:
Answer: It is 60 miles per hour
Step-by-step explanation: average speed = total distance / total time
Now you know the answer as well as the formula. Hope this helps, have a BLESSED AND WONDERFUL DAY!
