First, we need to standardize the value 1440 and 1465 to be able to work out the z-score
![z= \frac{1440-1450}{8.5}](https://tex.z-dn.net/?f=z%3D%20%5Cfrac%7B1440-1450%7D%7B8.5%7D%20)
![z=-1.77](https://tex.z-dn.net/?f=z%3D-1.77)
![z= \frac{1465-1450}{8.5}](https://tex.z-dn.net/?f=z%3D%20%5Cfrac%7B1465-1450%7D%7B8.5%7D%20)
![z=1.77](https://tex.z-dn.net/?f=z%3D1.77)
The z-scores are shown in the diagram below
To work out the probability of
![-1.77\ \textless \ z\ \textless \ 177](https://tex.z-dn.net/?f=-1.77%5C%20%5Ctextless%20%5C%20z%5C%20%5Ctextless%20%5C%20177)
we can first read on the table, the probability when
![P(z\ \textless \ 1.77)=0.9616](https://tex.z-dn.net/?f=P%28z%5C%20%5Ctextless%20%5C%201.77%29%3D0.9616)
, then we subtract this value from 1, as we are interested in the area to the right of 1.77.
![1-0.9616=0.0384](https://tex.z-dn.net/?f=1-0.9616%3D0.0384)
Then the area between
![z=-1.77](https://tex.z-dn.net/?f=z%3D-1.77)
and
![z=1.77](https://tex.z-dn.net/?f=z%3D1.77)
is
![1-2(0.0384)=0.9232](https://tex.z-dn.net/?f=1-2%280.0384%29%3D0.9232)
which is also the probability of lifespan between 1440 and 1465
Answer:
408in²
Step-by-step explanation:
Hello!
We can see that there are two sides with the side lengths 4in and 0.5ft(6 in), two sides with side lengths 4in and 1.5ft(18in), and two sides with side lengths 0.5ft(6in) and 1.5ft(18in). Multiply and add to find the Surface area (Area of all six faces)
Find the Surface Area:
- SA = 2(l * w) + 2(l * h) + 2(w * h)
- SA = 2(6in * 18n) + 2(6in * 4in) + 2(18in * 4in)
- SA = 216in² + 48in² + 144in²
- SA = 408in²
The surface area is 408in²

Answer:
the answer Is D.2
Step-by-step explanation:
9 is greater than 7 by 2
Answer:
1/3
Step-by-step explanation:
6 of 18 = 6/18
Divide by 6, the GCF of the two numbers 6 and 18, to get 1/3.
6 is 1/3 of 18.
