Answer:
c.Conformity increased rapidly as group size went up, but then leveled off at about 7 people.
Step-by-step explanation:
The conformity increased steadily as the group size went up, but then leveled off at about seven people.
Asch's studies 1956 depicted that group size impact whether subjects conformed or not. The study has revealed that bigger the size of group, more the number of people conformed. But again it was limited to a certain point. Increasing the size of majority beyond three, it was found out that it did not increase the levels of conformity.
Answer:
ft tall
Step-by-step explanation:
We must follow the indications:
Ryan is 4 1/2 ft. tall.
Ryan = ![4\frac{1}{12} ft](https://tex.z-dn.net/?f=4%5Cfrac%7B1%7D%7B12%7D%20ft)
He is 3 in. taller than his sister Lizzie. to find how tall is Lizzie we need to substract 3 inches from the height of Ryan, but we can only substract the quantities if they are in the same units.
Thus we convert the 3 inches to feet, since we 1 feet = 12 inches:
![\frac{1}{4} feet=3inches](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20feet%3D3inches)
so the height of lizzie:
![4\frac{1}{12}ft-\frac{1}{4}ft\\ \\](https://tex.z-dn.net/?f=4%5Cfrac%7B1%7D%7B12%7Dft-%5Cfrac%7B1%7D%7B4%7Dft%5C%5C%20%20%5C%5C)
we convert the first mixed number to fraction by multiplying 4 by 12 and adding the numerator 1:
![4\frac{1}{12}=\frac{4*12+1}{12}=\frac{49}{12}](https://tex.z-dn.net/?f=4%5Cfrac%7B1%7D%7B12%7D%3D%5Cfrac%7B4%2A12%2B1%7D%7B12%7D%3D%5Cfrac%7B49%7D%7B12%7D)
the subtraction becomes:
![\frac{49}{12}ft-\frac{1}{4}ft\\ \\=\frac{49*4-12*1}{12*4}\\ \\=\frac{196-12}{48}\\\\=\frac{184}{48}\\ \\=\frac{46}{12} \\](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B12%7Dft-%5Cfrac%7B1%7D%7B4%7Dft%5C%5C%20%20%5C%5C%3D%5Cfrac%7B49%2A4-12%2A1%7D%7B12%2A4%7D%5C%5C%20%5C%5C%3D%5Cfrac%7B196-12%7D%7B48%7D%5C%5C%5C%5C%3D%5Cfrac%7B184%7D%7B48%7D%5C%5C%20%5C%5C%3D%5Cfrac%7B46%7D%7B12%7D%20%5C%5C)
![=\frac{23}{6}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B23%7D%7B6%7D)
Lizzie is 23/6 ft tall.
She is 3/4 of a foot taller than her sister Emma, thus we must substract 3/4 from the height of Lizzie to find the height of Emma:
![\frac{23}{6}ft-\frac{3}{4}ft\\ \\=\frac{23*4-6*3}{6*4}\\ \\=\frac{92-18}{24}\\ \\=\frac{74}{24}\\ \\=\frac{37}{12}\\ \\=3\frac{1}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B23%7D%7B6%7Dft-%5Cfrac%7B3%7D%7B4%7Dft%5C%5C%20%20%5C%5C%3D%5Cfrac%7B23%2A4-6%2A3%7D%7B6%2A4%7D%5C%5C%20%5C%5C%3D%5Cfrac%7B92-18%7D%7B24%7D%5C%5C%20%5C%5C%3D%5Cfrac%7B74%7D%7B24%7D%5C%5C%20%5C%5C%3D%5Cfrac%7B37%7D%7B12%7D%5C%5C%20%5C%5C%3D3%5Cfrac%7B1%7D%7B12%7D)
Emma is
ft tall.
