What evidence do Gerstel and Sarkisian give that social class is even more important than ethnicity in understanding differences among families? Why is this a critical distinction to the authors?

As per Gerstel and Sarkisian, the social class is more significant than ethnicity to understand the dissimilarities between family ties as well as the behavior of ethnic groups. To substantiate their claim, they have compared the distinct ethnic groups and developed a database that helped in examining the distinctions in the practical, financial, and emotional relationships of each group and this also supported their claim. It contains critical distinction to the authors because their assumptions lack a universal approach and apply to certain conditions.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
