To find the mean you add all the #'s and divide by how many there are. 4+5+6+7 +8= 30 /5 is 6. Tara is right.
Answer:
41.86 miles each hour
Step-by-step explanation:
Kelli and her family went to the beach for a vacation. They drove 293 miles in 7 hours to get there. ABOUT how many miles did they drive each hour?
This Question is calculated as:
7 hours = 293 miles
1 hour = x miles
Cross Multiply
7 hours × x = 1 × 293 miles
x = 293 miles/7 hours
x = 41.857142857 miles per hour
x ≈ 41.86 miles per hour
Hence, they drove 41.86 miles each hour
Find out how much you need for one person then multiply by 18 is one way you could do this..
4 divided by 24 = 0.166666666666667 x 18 = 3 litres of lemon-lime soda.
2 divided by 24 = 0.083333333333333 x 18 = 1.5 pints of servet
6 divided by 24 = 0.25 x 18 = 4.5 cups of ice.
Hope this helps!
Your teacher may have wanted you to (some how) use your 6x tables to work this out?!
Answer:
(2) (100, 300)
Step-by-step explanation:
One wave can be divided on 4 parts, as show on the picture.
Since a length of one whole wave equals 400, a length of each part is 
nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
