Answer:
Mean = 1.9
Standard deviation = 0.6
Step-by-step explanation:
The Mean is calculate by the formula:
⇒ 
Thus Mean to the nearest tenth is 1.9
Standard Deviation is the square root of sum of square of the distance of observation from the mean.
where, 
is mean of the distribution.
Putting all values in the formula, We get
Standard Deviation = 0.597 ≈ 0.6
Answer: T = 4c + 4t + 3s
Step-by-step explanation:
Stocks contains:
4-legged chairs
4-legged tables
3-legged stools
So, 1 chair has legs = 4
So, c chairs has legs = 4c
1 table has legs = 4
So, t tables has legs = 4t
1 stool has legs = 3
So, s stools has legs = 3s
Let T denotes the total no. of legs
So, the total number of furniture legs in aisle 2 :
T = 4c + 4t + 3s
The base of the triangle is 6 - 2 = 4 units
The height is 6 - 1 = 5 units
Area = 1/2 x 4 x 5 = 10 square units
Answer:
4 1/12 sq. ft
Step-by-step explanation:
To know the amount of area that Pete’s bed have more than Fluffy’s bed, we simply calculate the area of both beds then subtract the smaller from the larger.
The area of Fluff’s bed would be 3 * 21/12 = 63/12 Sq ft
The area of Pete’s bed would be 4 * 28/12 = 112/12 sq ft
The difference in area is thus: 112/12 - 63/12 = 49/12 = 4 1/12 sq. ft
