Answer:
The weights within this range are:
8.9
9.5
9.8
10.4
Step-by-step explanation:
The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:
9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)
8.5 ≤ x ≤ 10.5
The answer would be 240 since you are only looking for surface area, which means you wouldn’t include the width
Answer:
3.33
Step-by-step explanation:
Answer:
W=5.3, l= 15.6
Step-by-step explanation:
Perimeter of a rectangle p=2(l+w)
P= 42
W= x
L= 5+2x therefore 42=2(5+2x+x)
42=10+6x , 32=6x
Make x subject of formula
X=32/6 x=5.3 there for w=5.3
Where L= 5+2x ; L=5+2(5.3)
L therefore = 15.6
Let's start with option A --> $23 per hour x 40 hours = 23 x 40 = 920 = $920
That means we have to find how many $ x 5% = $920
We'll call our unknown amount: "B", so B x 0.05 = $920
To find B you have to get ride of everything on its side:
(B x 0.05) / 0.05 = 920 / 0.05 ----> we have to do the same operations on each side.
Now we have B = 920 / 0.05 ----> B = $18,400
The salesperson must sell $18,400 in order to earn the same amount as the first option.
