Answer: The range of the tree heights at yard work is greater than the range of the tree heights at the grow station
Step-by-step explanation:
yard works: 7,9,7,12,15
The grow station:9,11,6,12,7
mean of yard works = 7+9+7+12+15/5
=50/5=10
mean of grow station=
9+11+6+12+7 /5
=45/5 =9
The mean of tree heights at yard work is greater than that of grow station.
median(tree at yard work):7,7,9,12,15
median=9
median(tree at grow station)=6,7,9,11,12
median=9
The median of the tree height at yard work is equal to the median of that of tree station.
Range(yard work) = 15 - 7 =8
Range (tree station) =12-6=6
The range of the tree heights at yard work is greater to the tree heights at that of tree station
<h3>Given :</h3>
- Distance = 175
- Time 1 = 4 hours
<h3>To find:</h3>
- Different between two speeds when distance is same.
<h3>Solution:</h3>
<u>Part</u><u> </u><u>1</u><u> </u><u>:</u>
In first part we will find speed 1 in which time is 4 hours
we know:-
So:-
<u>Part 2</u>
In first part we will find speed 2 in which time is 3 hours
Again:
<u>Part 3</u>
In this part we will find different between speed 1 and speed 2
So :
Answer:
Step-by-step explanation:
Total pencils = 48
Total erasers = 72
If we put 1 pencil and 1.5 eraser in each pouch then total pouches = 48 pouches
A) 122 in^2, this is because 3 x 7 x 2= 42, 4 x 7 x 2= 56, 3 x 4 x 2= 24, once you add up all the sums it equals 122
Step-by-step explanation:
▪ diameter of yellow = 9+2.5×2 = 9+5 = 14cm
▪ circumference of yellow = piie × diameter = 14piie cm
