The cost price of each pair of socks is 3 dollars and 97 cents
The total money paid by Jessica for 4 pair of socks = $20
The money that the cashier returned = $4.12
It is also given that, each pair of sock would cost same price
We need to find, The cost price of each pair of socks
To do that, first let's find
The amount that was paid for 4 pair of socks = 20 - 4.12 = $15.88
Now,
The cost price of one pair of sock = 
= $3.97
= 3 dollars and 97 cents

Answer:
for the triangle on top on side is 8 one side is 4 so if we use the theorem
64+16=80
a=9
so
Side a = 19.8242
Side b = 17.66349
Side c = 9
Angle ∠A = 90° = 1.5708 rad = π/2
Angle ∠B = 63° = 1.09956 rad = 7/20π
Angle ∠C = 27° = 0.47124 rad = 3/20π
Area = 79.48573
Perimeter p = 46.4877
Semiperimeter s = 23.24385
Given that variance of a data set is:
Variance=σ²
the standard deviation is the square root of the variance:
thus
standard deviation= √(variance)
variance,σ²=104.04
thus
std deviation=√σ²=√104.04
thus
σ=10.2
The answer is -1/36
Have a good day.
