Answer:
A = 16 cm²
Step-by-step explanation:
the shape is made up of 2 rectangles.
One on top with dimensions 4 cm by 2 cm
The one below with dimensions 2 cm by 4 cm
then total area (A) is the sum of the areas of the 2 rectangles
A = (4 × 2 ) + (2 × 4) = 8 + 8 = 16 cm²
Answer:
a) P [ x ≤ 7000] is 0.55
b) P [ x > 5000 ] = 0.95
c) P [ 5000 < x ≤ 7000 ] = 0,5
Step-by-step explanation:
a) P [ x > 7000 ] = 0.45 straightforward P [ x ≤ 7000] is 0.55
The whole spectrum of probabilities is 1 which in this particular case is divided in two parts having 7000 as a limit, then we subtact 1 - 0.45
b) P [ x ≤ 5000] = 0.05 again we get P [ x > 5000] taking 1-0.05 to get
P [ x > 5000 ] = 0.95
c) P [ 5000 < x ≤ 7000 ]
Under Normal curve distribution the probability of x ≤ 7000 includes values smallers ( to the left of 5000) so we subtract from 0.55 - 0.05 = 0.50
c) P [ 5000 < x ≤ 7000 ] = 0,5
Answer:
find below
Step-by-step explanation:
5(x-7)=20
5x-35=20
5x=55
x=11
I would need to see a picture of the shape to get a idea on how to solve this
Answer:
2.1 , 2.103 , 2.13 , 2.1312
Step-by-step explanation:
Look at the first place, and see if it's the same, if it is, then you move to the next place. If the place is empty, fill it with a 0 and go from there.
