Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6
Step-by-step explanation:
Given
Total fabric = 27 yards
Dresses to be made = 5
In order to find the measurement of fabric for one dress, the total fabric will be divided by number of dresses to be made.
So,
![Fabric\ for\ one\ dress = \frac{Total\ fabric}{No.\ of\ dresses}](https://tex.z-dn.net/?f=Fabric%5C%20for%5C%20one%5C%20dress%20%3D%20%5Cfrac%7BTotal%5C%20fabric%7D%7BNo.%5C%20of%5C%20dresses%7D)
![Fabric\ for\ one\ dress = \frac{27}{5}\\=5.4\ yards](https://tex.z-dn.net/?f=Fabric%5C%20for%5C%20one%5C%20dress%20%3D%20%5Cfrac%7B27%7D%7B5%7D%5C%5C%3D5.4%5C%20yards)
The answer lies between the whole numbers 5 and 6
Hence,
Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6

Answer:
2.25
Step-by-step explanation:
The total frequency is:
20 + 12 + 6 + 2 = 40
Calculate the probability of each score:
P(X=3) = 20/40 = 0.50
P(X=2) = 12/40 = 0.30
P(X=1) = 6/40 = 0.15
P(X=0) = 2/40 = 0.05
So the expected value is:
E = (3)(0.50) + (2)(0.30) + (1)(0.15) + (0)(0.05)
E = 2.25
